Rev 2.1 ~ Aug 2014 Page 3 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Introduction to the Galaxy RS485 Door Module Feature
This is an addendum to the 635/600 Hardware Install Guide. This manual only covers the installing and configuring the NEW Galaxy RS‐485 Door Module Feature in the related hardware and software settings. General hardware and software installation instructions are covered in the main hardware and software guides.
System Galaxy 10.4 introduces the Galaxy 485 Door Module Feature, which allows dropping multiple 635‐DRMs (Reader Boards) onto the RS‐485 Channel of the 635‐DSI Board running Hardware Flash v10.0. FEATURE ADVANTAGES: 
Supports remotely locating DRMs (Dual Reader Modules) when using RS‐485 2‐wire communication. 
Allows for increasing reader line distance; up to 4,000 total line distance. Potential to decrease the amount of wiring needed for a more cost effective solution. 
Ability to retrofit existing access control systems that utilize remotely located reader connections. 
Supports single‐door or dual‐door multi‐drop configurations based on DRM dipswitch setting. Rev 2.1 ~ Aug 2014 Page 4 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration RS485 Door Module Topologies Explained:
This section provides visual diagrams for the installation topology. The installation steps are described in later sections of this guide. Reader/Lock Numbering for Single-Door Installation ( up to 16 DRMs & 16 DOOR/LOCKS) :
The figure below shows the RS485 Door Module Topology for Section‐1 of the DSI (Dual Serial Board). 
You must use all 635‐series hardware (CPU, DSI, DRMs). The 635‐CPU has a max. device load of 64 devices. 
The 635‐DSI is installed in the main control panel (up to 16 doors per Section; 32 doors per board). 
The 635‐DRMs are installed in a small panel at or near the door; up to 4,000 feet line distance from the DSI board on the RS485 2‐wire run. Readers can be installed up to 500 feet from the DRM board. 
In this configuration, the Reader Number and the DRM board address will be the same value (i.e. Door‐1 is on Board‐1, Door‐2 is on Board‐2, and so on. 
Also the DRM Section‐2 must be disabled (Dipswitch Option B = OFF). Figure 1: SINGLE‐DOOR TOPOLOGY 635‐DRMs are located at or near the door. When installing a Single‐Door Topology, the DRM board address also serves as the Reader number. See figure‐2 for Two‐Door Topology. Rev 2.1 ~ Aug 2014 Page 5 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Reader/Lock Numbering for Dual-Door Installation (up to 8 DRMs & 16 DOOR/LOCKS):
The figure below shows the RS485 Door Module Topology for Dual‐Door Module installation. It is very important to get the board addresses correct. System Galaxy will assign the reader numbers based on the DRM board address. In this configuration you will only need 8 DRMs to support the 16 doors. Each DRM will be given an odd number of 1, 3, 5, 7, 9, 11, 13, and 15. 
You must use all 635‐series hardware (CPU, DSI, DRMs). The 635‐CPU has a max. device load of 64 devices. 
The 635‐DSI is installed in the main control panel (up to 16 doors per Section; 32 doors per board). 
The 635‐DRMs are installed in a small panel at or near the door; up to 4,000 feet line distance from the DSI board on the RS485 2‐wire run. Readers can be installed up to 500 feet from the DRM board. 
In this configuration, the DRM Board Address and Reader Number on Section‐1 will always match (i.e. Door 1 is on Section‐1 of Board 1, Door 3 is on Section‐1 of Board 3 and so on). 
Also the DRM Section‐2 must be enabled (dipswitch option B = ON). Figure 2: TWO‐DOOR TOPOLOGY When installing a Two‐Door Topology, the Reader Number on Section‐1 will match the DRM Board Address. All DRMs must be given an odd‐numbered address (1, 3, 5, 7…15) to make room for even numbers on Section‐2. The same numbers must be correctly matched when assigning the readers in the System Galaxy software. Only Section‐1 is shown, but Section‐2 can also be configured for the same RS485 Door Module support or for a different type of device such as relays, wireless readers, LCD displays, etc. Rev 2.1 ~ Aug 2014 Page 6 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Reader/Lock Numbering for Mixed Single-Door & Dual-Door Installation (up to 16 DOOR/LOCKS):
The figure below shows the RS485 Door Module Topology for a mixture of Single‐door and Dual‐Door modules. It is very important to get the board addresses correct. System Galaxy will assign the reader numbers based on the DRM board address. In order to support 16 doors in this type of configuration, you will need between 9 and 15 DRMs – the exact number depends on how many dual door setups you use. DRMs can be given an even or odd address, but the Board address will still match the reader on section‐1. 
You must use all 635‐series hardware (CPU, DSI, DRMs). The 635‐CPU has a max. device load of 64 devices. 
The 635‐DSI is installed in the main control panel (up to 16 door/locks per Section; 32 doors per board). 
The 635‐DRMs are installed in a small panel at or near the door; up to 4,000 feet line distance from the DSI board on the RS485 2‐wire run. Readers can be installed up to 500 feet from the DRM board. 
In this configuration, the DRM Board Address will match the Reader Number on Section‐1 (i.e. Door 1 is on Board 1, Door 3 is on Board 3 and so on). 
On each DRM Section‐2 must be enabled or disabled as appropriate (enable section‐2 by placing dipswitch Option B = ON; disable section‐2 of the DRM by placing Option B = OFF). Figure 3: MIXED TOPOLOGY – Single‐Door and Two‐Door Mixed Numbering DRM Board Addresses match the Reader Number on Section‐1 of the DRM. In this configuration, the Board Address could be an odd or even number depending on the number of readers on the preceding DRMs. Only Section‐1 is shown, but Section‐2 can also be configured for the same RS485 Door Module support or for a different type of device such as relays, wireless readers, LCD displays, etc. Rev 2.1 ~ Aug 2014 Page 7 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration 635-DSI BOARD CAPABILITIES:

Rev 2.1 ~ Aug 2014 Page 9 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration 635-DSI Board Installation Requirements:
These requirements below are specific to installing, configuring and operating the 635 Hardware to support the new Galaxy RS485 Door Module Feature. IMPORTANT: Hardware & Software requirements that are outside the scope of this feature may not be mentioned herein. Consult the main Hardware and Software Guides. 1. The Galaxy RS485 Door Module is supported in System Galaxy 10.4 (or later) running S28 Flash v10.0 (or later).  All Galaxy hardware boards (i.e. CPU, DSI, DRMs) must be the 635 model number when supporting the Galaxy RS485 Door Module installation.  All boards must be loaded with the correct flash that comes with the SG software. 2. The 635‐DSI Board is only compatible with a 635‐CPU Board:  The 635‐DSI is not compatible with the older 600‐CPU under any circumstance.  The 600‐DSI/CPU/DPI does not support the Galaxy RS485 Door Module feature.  System Galaxy 10.4 Software supports the S28 Flash version 10.0.  IMPORTANT: Installer must FLASH each CPU with the v10.0 Flash before the loading data.  The daughter boards no longer auto‐flash after a 10‐minute delay as in prior versions. You must click the [Send Board Flash Updates] button in the Loader or the 635 Web Config Tool to initiate flashing. 3. SG 10.4 continues to support 600‐series controllers and 635‐series controllers on the same loop/cluster. 4. Expanding/Upgrading an Existing System: you must replace the 600‐CPU with a 635‐CPU only in the control panel(s) that provide RS485 communication to remote RS485 Door Modules. You do not need convert other 600 panels that do not support the remote door modules. 5. When installing the RS‐485 Door Module Feature: you must use 635‐DRM Reader Boards in the remote door module and you must use a 635 DSI in the main Galaxy control panel for RS485 communication. 6. RS‐485 2‐wire Comm Cable: Cat‐5 or 22AWG twisted pair is recommended; overall shield offers best noise protection. If using shielded cable, the drain‐wire must be grounded at one end only of every wire‐run segment when installing the boards in a multi‐drop fashion. 7. DSI 485 Board supports* up to 16 Readers/Locks per RS‐485 Section (*within 4,000 ft RS485 line distance). Rev 2.1 ~ Aug 2014 Page 10 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration 8. DSI Board 8‐position Dipswitch Settings: a. OPTION‐A (the 8th position) unused. b. OPTION‐B (the 7th position) unused. c. OPTION‐C (the 6th position) Baud Rate for Galaxy 485 Multi‐drop Feature: OFF = Default. IMPORTANT: This switch position must match the attached DRM Boards Baud Rate setting. d. You must press the RESET (SW‐1) on the board any time you change a dipswitch setting. e. The first 5 positions are binary settings, used to address the Board ID. [ IDs must be unique within the panel; ID’s 1 thru 16 are valid ] – see the install instructions for details.

DSI Termination Jumpers (JP4/JP5) must be installed correctly for each section. Leave jumper in the OPEN position if the board is not at end of line. Place jumper in the TERM position only if the DSI Board is installed at the end of line (applies to first and last board); 10. DSI Auxiliary Power Jumpers (JP1/JP2) must be set to the correct position (unset = factory default). a. If using onboard internal power output, set to +12Vdc (max 150 milliamps allowed). b. If using external low‐current power applied to J2 pin‐3, set to +24V (250 milliamps max. allowed). CAUTION: When applying power to J2 Pin‐3, do not exceed 250 milliamps of current draw. CAUTION: When using +12V internal board power, do not exceed 150 milliamps of current draw. WARNING: Exceeding current draw will damage board and cause equipment/system failure. Rev 2.1 ~ Aug 2014 Page 11 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration 635‐DRM Reader Board Installation Requirements: The requirements below are specific to installing the DRM Boards on the DSI RS‐485 ports (sections). 1. The 635‐DRMs S28‐flash version must match the S28‐flash installed on the 635‐DSI and 635‐CPU Boards (which must be 10.0 or higher). 2. Reader/Lock wiring: 22AWG twisted pair is recommended; overall shield for best noise protection. When using shielded cable, ground the drain‐wire at one end only on the COM contact of the DRM. 3. 635‐DRMs supports up to 2 readers/locks per board for the Galaxy 485 Multi‐drop Feature: The 635‐DRM can be configured to control (a) one reader/lock (on Section‐1); or (b) two Readers/Locks (using Section‐1 & ‐2). The on‐board dipswitch Option‐B is used to enable or disable section‐2. c. If installing one reader per DRM Board, up to 16 DRMs can be added to a DSI 485 section. With this configuration the reader/lock must be installed on section‐1 of the DRM. The DRM Board ID will be the same as the Reader/Lock number on section‐1. d. If installing two readers per DRM Board, up to 8 DRMs can be added to a DSI 485 section. In this configuration the readers/locks are be installed on both sections of the DRM. In this case the DRM Board ID will be the same number as the Reader/Lock number on section‐1. e. You can install a mix of configurations (i.e. some DRMs having only one reader (Section‐1) and some DRMs having two readers installed (using both Section‐1 and 2). In this case the DRM Board ID will be the same number as the Reader/Lock number on section‐1. SEE THE INSTRUCTIONS FOR DETAILS AND DIAGRAMS. 4. DRM DIPSWITCH SETTINGS for the Galaxy 485 Multi‐drop Feature : a. OPTION‐A (the 8th position) is unused. b. “Enable Section‐2” OPTION‐B (the 7th position): this option is for the Galaxy 485 Multi‐drop Feature. OFF = Section‐2 disabled; only Section‐1 is operational (i.e. Reader/Lock must be installed on section‐1); ON = Section‐2 enabled; both sections are in use (i.e. Readers/Locks are installed on both sections). c. “Baud Rate setting” OPTION‐C (the 6th position) is the: only for the Galaxy 485 Multi‐drop Feature. OFF = 19200 BPS; ON = 57600 BPS. This must match the DSI Baud Rate setting. d. DRM Board ID: The first 5 positions are used to set the ( ID’s 1 thru 16 are valid on the RS‐485 multi‐drop ). IMPORTANT: when installing DRMs on a DSI RS‐485 wire‐run (section), you must consider whether you are adding one or two readers on each DRM in order to know how to address the DRM Board IDs. Since you cannot duplicate a reader address on a RS‐485 port/section, the DRM Board ID must match the reader address on Section‐1 of the DRM. – see the instructions for details. e. You must RESET (SW‐1) on the board any time you change a dipswitch setting. Rev 2.1 ~ Aug 2014 Page 12 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration System Galaxy Software Requirements:
The requirements below are specific to configuring the system to support the new RS485 Door Module Feature. To see the full
scope requirements, refer to the SG 10.3 System Specification Guide and SG 10.3 Software User Guide.
1. System Galaxy 10.3 Software is required to support the 635‐DSI Board. 2. System Galaxy 10.3 Software is required to support the Galaxy RS485 Door Module Feature. 3. No feature‐specific registration or workstation‐specific settings are required to use this functionality. 4. After adding the controller(s) into the SG Controller Properties screen, you must import the 635‐DSI board(s) with the [Get Board Info] button. 5. CAUTION ‐ for systems that are upgrading existing controllers: You must flash all controllers up to the v10.0 S28 flash or later* ( *or the Flash version that is current with the software in later versions of SG). The Controller properties screen provides separate options to Bypass Flash Loading and Bypass Data Loading. a. The Bypass Data Loading feature is provided to help installers protect boards from be data loading before they have been flashed. Loading data before panel is properly flashed can cause corruption to memory sectors on the DSI/DRM boards. Be aware that when checked, this option will cause the Event Server to block all forms of data loading (i.e. from the GCS Loader program and from the DataLoader service, as well as a user changes made by clicking the APPLY button in a programming screen). Unchecking the Bypass Data Loading will allow loading from all methods of loading. b. The Bypass Flash Loading allows installer to control how many panels get flashed at a time on the same loop. Large systems will benefit from flashing the panels in groups or subsets. Checking the option will block Loading from the SG Software and GCS Loader utility program. Unchecking the Bypass Flash Loading will allow loading from all methods of loading. 6. The DSI Serial Channel must be configured in the SG software to properly support the “RS‐485 Door Module” features. 7. The Reader Properties must also be configured correctly according to the correct reader technology used at the Door Module. 8. Once configuration is completed, the panels must be loaded with the programming data.

4. Set the dipswitches on the DRM boards before they are installed at the remote locations.
JUMPER AND DIPSWITCH SETTINGS WILL BE INITIALIZED WHEN THE BOARD IS POWERED UP. AFTER THAT, IF YOU CHANGE THE SETTINGS YOU MUST PRESS THE SW‐1 RESET SWITCH TO CAUSE SETTINGS TO BE READ. a. OPTION-B ENABLING DRM SECTION-2 (Reader/Lock): Place switch 7 in the desired
position.
ON/UP Enables section-2 of the DRM (use this setting if installing 2 readers on the DRM)
OFF/DOWN disables section-2 of the DRM (use this setting if only installing 1 reader)
b. OPTION-C - SETTING THE BAUD RATE: Place switch 6 in the desired position.
ON/UP is 57600 BPS (faster communication speed)
OFF/DOWN is 19200 BPS (cleaner packet transfer; factory default)
THIS SETTING VALUE APPLIES TO BOTH RS485 Sections/ports. All DRM Reader boards
must be set to the same value. The DSI option-C must match.
c. SETTING THE BOARD ID: Place switch positions 1 thru 5 in the desired positions to be a
valid/unique number. Ensure that the Board ID number is unique on the 485-channel.
The DRM board ID must match the reader number on it’s section-11thru 16 is valid).



When installing 1 reader per DRM, the DRM ID matches the reader # on section-1.
When installing 2 readers per DRM, the DRM ID will match the reader # on section-1.
When installing a mix of single-reader and dual-reader boards, always make the DRM ID
match the reader on section-1.

Rev 2.1 ~ Aug 2014 Page 18 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Wiring the DSI RS-485 Two-Wire Connectors:
5. Wire the 4-pin orange connectors for the DSI RS485 ports/sections to the DRM 485 Boards.
a. Section 1 and 2 operate independently. You do not have to use both sections of the DSI board. You can
use either section for the 485 multi-drop. Optionally, you can use one section of the DSI for the DRM 485
Multi-drop and the other section for the same or different technology. However you cannot mix technologies
within the same channel/section.
b. You can support up to 16 Readers/Locks per DSI 485 port/section within the 4,000 foot line distance,
using the appropriate number of DRMs to facilitate the readers.
c. Each DRM can optionally support 1 reader (Option-B OFF) or 2 readers (Option-B ON). You can
configure all the DRMs to support 1 reader, or all DRMs to support 2 readers, or you can have a
mixture.
IMPORTANT: The DRM’s Board ID must match the Reader/Lock Number on Section-1 of the
DRM. See chart on next page.
Figure 11: Wiring diagram for DRM RS‐485 Door Module Rev 2.1 ~ Aug 2014 Page 19 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Wiring the DRMs and Readers:
6. Wire the -pin orange connectors for the DRMs RS485 port/section to the DSI 485 CHANNEL.
a. When wiring DRM reader boards onto the RS45 multi-drop, they will be arranged in a daisy-chain
configuration.
7. Wire the reader, locks, REX and door contact to section-1 of the DRM as you normally would
when installing a standard controller setup.
8. IF using section-2, wire the reader, locks, REX and door contact to section-2 of the DRM as you
normally would when installing a standard controller setup. Option-B must be ON.
Reader distance from the DRM is 500 feet. Use 22 AWG shielded, twisted pair to connect reader. Figure 12: Wiring diagram for DRM RS‐485 Door Module Rev 2.1 ~ Aug 2014 Page 20 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration SOFTWARE PROGRAMMING:
Software Programming:
1. Once the hardware installation is completed, you must install and program the software.
Follow the instructions in the Installation Guide/ Install DVD Help and the Software User Guide.
2. Register your System and Workstations properly.
IMPORTANT: the max number of readers must include the reader count that will be installed on
the RS485 Door Modules when installed on the DSI 485 channels.
a. After registering the software, you can begin programming the hardware into the System Galaxy
software.
Create the Loops:
1. Create the loop(s) for the hardware panels you installed. See the software Guide for instructions on
features outside the scope of this addendum.
2. From the menu, click Configure > Hardware > Loops.
3. Enter a descriptive Loop Name.
4. Enter the Loop IP Connection parameters
5. Enter the ID of the Communication Server (click [This Machine] if you are working from the Comm Server
(recommended). Note: on rare occasions a machine name cannot be resolved; therefore it may be
necessary to enter the raw TCP/IP Address of the Comm Server.
Rev 2.1 ~ Aug 2014 Page 21 of 31 Galaxy RS‐485 Door Module Addendum Installation & Configuration Program the Controller(s):
1. Create the controllers. From the menu, click Configure > Hardware > 635 Controllers.

4. Check or uncheck the Bypass Flash Loading or Bypass Data Loading options as needed.
NOTE: The Bypass Flash Loading and Bypass Data Loading are now separate options. This is
useful for systems that are upgrading, especially very large systems that must update the control
panels in sections. These Event Service blocks the control panel from loading flash or data when the
GCS Loader is executed for a selected loop. Also data loads that are issued by the DataLoader or by
clicking the APPLY button in a programming screen will now be blocked when Bypass Data Loading
option is checked.
CAUTION: When upgrading a controller panel, DO NOT ALLOW A DATA LOAD BEFORE THE
PANEL HAS HAD FLASH BEEN LOADED AND BURNED. Premature data loading can permanently
damage the board memory resulting in undesired hardware operation. Panels must be flashed to
the S28 Flash v 10.0 or later*. (* for versions later than 10.0, panels must be flashed to the s28 version
released with SG.)
