5.4.2 HIGH SIDE DRIVER OUTPUT

The high side driver output is connected to pin 14 (OUT 2) of J5. The high side driver will pull
the signal to VBAT when active. The high side driver output can source up to 200 mA of current.

5.4.3 RSSI OUTPUT

The RSSI output is connected to pin 13 (RSSI) of J5. The RSSI output reflects the received signal
strength of the satellite signal. The RSSI output will range from 0 volts to 2.7 volts. A higher
RSSI voltage indicates a stronger received signal. The current RSSI value is available with the
‘

rssi

’ command.

The RSSI is also available on the test port connector as shown in Appendix C.

5.4.4 PWM OUTPUT

The PWM output is connected to pin 16 (PWM) of J5. The PWM signal can generate a
modulated signal with a range of 0 to 3.3 volts with a current of < 100 uA.

This output is currently not implemented in the firmware.

5.5 RTU

Port

The RTU Port is a full RS232 port configured as DTE with the following signals:

Receive is an output connected to pin 16 (RX) on J3.
Transmit is an input connected to pin 17 (TX) on J3.
RS232 Signal ground is connected to pin 18 (GND) on J3.
Request to send is an input connected to pin 19 (RTS) on J3.
Clear to send is an output connected to pin 20 (CTS) on J3.
Data terminal ready is an input connected to pin 21 (DTR) on J3.
Data set ready is an output connected to pin 22 (DSR) on J3.
Carrier detect is an output connected to pin 23 (CD) on J3.
Ring indicator is an output connected to pin 24 (RI) on J3.
