SIM100 NMEA 2000 ® Periodic Data Transmitted PGNs
PGN 127501 – Binary Switch Bank Status
The SIM100 uses this PGN to transmit the state of each of the connected switch inputs
Field 1: Indicator Bank Instance – This field identifies the particular switch bank to which this
PGN applies. Please refer to Section 2.5.1 for instructions on how to program the
value of this field.
2: Indicator #1 – This field indicates the state of the switch connected to the SW1A and
SW1B inputs of the SIM100. The state will be one of the following values:
• “Closed” – The monitored switch is closed.
• “Open” – The monitored switch is open.
• “Error” – There is an open connection between the SIM100 and the monitored
switch. This state can occur only when the indicator is configured to use an
End of Line Resistor.
• “Data Not Available” – The indicator is configured as “Disabled”
3: Indicator #2 – This field indicates the state of the switch connected to the SW2A and
SW2B inputs of the SIM100.
4: Indicator #3 – This field indicates the state of the switch connected to the SW3A and
SW3B inputs of the SIM100.
5: Indicator #4 – This field indicates the state of the switch connected to the SW4A and
SW4B inputs of the SIM100.
6: Indicator #5 – This field indicates the state of the switch connected to the SW5A and
SW5B inputs of the SIM100.
7: Indicator #6 – This field indicates the state of the switch connected to the SW6A and
SW6B inputs of the SIM100.
