Introduction
NMEA0183 tester SIM183 is a handheld portable tester for testing transmit-received
NMEA0183 signals, with lithium battery for 9-hour continuous working. SIM183 can
receive and display NMEA0183 signal from an external device, and test baud rate and
peak value of the received signal. It also can send the selected NMEA0183 sentence
(optional 142 kind of NMEA0183 sentences) and the baud rate of the transmitted
signal can be set. In practical operation, NMEA0183 tester SIM183 can be applied for
the installation, debugging and trouble removal.
Features
 Built-in rechargeable battery, with portable and well-adapted
 Real-time read and display NMEA0183 sentences
 Test the peak value of received signals
 Auto test baud rate of received signals
 Send optional 142 kind of standard NMEA0183 sentences
 Customizable parameters in common NMEA0183 sentences for sounder and
speedlog
 Big screen green with black words on LCD display
Functions
NMEA0183Receiver：Read and test the received NMEA0183 signals. Real-time
display the received NMEA0183 sentence and test the peak value and baud rate.
NMEA0183 Sender：Send the standard NMEA0183 sentences (optional 142 kinds) to
an external device. According to INITIAL or COMMON DEVICE, select the relevant
sentences. In addition, users can set the information of DPT sentence used in echo
sounder, and VBW and VLW sentences used in speedlog.
Send Baud Set：Set baud rate of NMEA0183 signal sending to an external device.

Operation
NMEA RECEIVER
Properly connect the RX interface of the tester SIM183 to the NMEA0183output port
of an external device. If NMEA0183output port of an external device works normally,
the red light will flash; If the NMEA0183 output wires of an external device are
inversely connected, the red light will be normally on and users should connect the
wires inversely; If no matter normally or inversely connect the NMEA0183 output
wires of an external device, the red light will not work, which means the NMEA output
ports of an external device are abnormal. There is no NMEA0183 signal output or
output voltage is too low. Users can select SIGNAL TEST item of SIM183 to further
test the received NMEA0183 signal.
1. SHOW MESSAGES
Show the NMEA0183 output sentences from the external device.
In the main menu, press
and then press
to move the cursor and select ‘1. NMEA RECEIVER’,
to enter the secondary menu. Select ‘1. SHOW MESSAGES’ to
start show the received signal. And press
to pause receiving signals for a complete

In the main menu, press
and then press
to move the cursor and select ‘1. NMEA RECEIVER’,
to enter the secondary menu. Select ‘2. SIGNAL TEST’ to
measure and display the baud rate and peak value of the received signal. The range
of testing Baud rate is 2400, 4800, 9600, 19200 and 38400 bps and the range of peak
value is 0~15V. In additionally, the tester SIM183 provides the normal range of peak
value for user reference. And press
to return to the previous menu.
NMEA SENDER
Transmit the NMEA0183 signals to an external device (the yellow will be flashing).
Users can select the NMEA0183 sentences to send to an external device. The data in
the sentence can be set as 123456789, such as 12.3kn, 123.4m. The optional 142
