- Page 2 Power/Ground Connection. The power (PWR) and ground (GND) connections are located at one end of the terminal strip. The power source can be anywhere in the 8-30 Vdc range. There is no ON/OFF switch on the AM43 due to its low power consumption.
- Page 3 PC for this interface. NMEA 0183 Inputs. The four AM43 input connections are labeled IN1, IN2, IN3, and INh. IN1 – IN3 are set for 4800 baud, but IN1 can be reprogrammed to 9600 baud, if required (see Appendix A). INh is a hi-speed input, which is set to 38,400 baud.
- Page 4 TLK Output. This output is specifically for data from the PC (via USB). This would normally be data such as waypoints, routes, or steering commands. The data rate is fixed at 4800 baud. A special feature of the AM43 is its ability to redirect OUT data to the TLK terminal when data from the PC is lost.
- Page 5 USB connection and a simple terminal program (see Appendix A). Status LED. A multicolor LED sits in a recess on top of the AM43. The colors and their meaning are summarized in Table 2. The LED will only show one color at a time as determined by its priority. Yellow has highest priority to show an error has occurred.

4. TROUBLESHOOTING A useful feature of the AM43 is the detection and reporting of errors. There are five types of errors, which can be detected, in any of the five internal channels (4 inputs + talker). An error message identifies both the channels and types of errors that have occurred. - Page 7 As an example, the sentence $PNOLE,4,7 indicates that IN3 had sync, char, and dolr errors. We know this because 7 is the sum of 1(sync) + 2(char) + 4(dolr). Each of the five types of errors is assigned a binary power (1, 2, 4, 8, F). The sum of any of these binary powers equals a unique number, which can be decomposed into the simple error types.
- Page 8 Testing with Status LED The LED provides a convenient means to test the AM43 in place. This is because the AM43 will always produce an output whenever any of the five input channels (4 + talker) is stimulated. If valid data is detected, the LED will flash red, yellow, or green as appropriate and data will be sent to the proper output.
- Page 9 (e.g., Hyperterminal) is used for programming. Commands typed into the terminal window are sent to the AM43, which will check their validity and take appropriate action. All commands begin with an “@” character followed by another character which defines the action to take. Some actions will need additional characters (options) to more specifically define the action.
