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.
Signal transceiver interface Charging port LED Indicators: Yellow light will flash when transmitting NMEA0183 signals. Red light will flash when receiving NMEA0183 signals. Menu Navigation Buttons: Flashing cursor key to change the location of flashing cursor Increase/decrease key to increase/decrease parameter value...
Operation In the operation manual, take NLT 10’’ inch navigation sounder DS2008 as examples to describe the operation of NMEA0183 tester SIM183. Practically, SIM183 can as well transmit and receive the NMEA0183 signals with other devices. Charge Please charge when the battery is too low for extend the battery's life.
If NMEA0183 output 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;...
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 kind of NMEA0183 sentences are bellow.

Operation 1. INITIAL Press to enter INITIAL type and then press to move the cursor and select the initial of the sentence. Press to enter the window of all sentences with the selected initial. 2. COMMON DEVICE Press to enter COMMON DEVICE type and then press to select the device type simulated output by the tester SIM183.
Operation Especially, users can set the data parameters in DPT sentence for echo sounder, and VBW and VLW sentence for speedlog as needed. For example, the test is sending the VLW sentence to external speedlog repeater IR861. Select ‘c. SPEED LOG’ and press to enter the window of speedlog sentences.

According to the identity on SIM183, one end of the wire connects to the RX or TX interface of SIM183 and the other end connects to NMEA0183 signal output or input interface of an external device (NMEA A to SIG - A, NMEA B to SIG – B).
