4.1.7 Fault Output
The radio modem has a sourcing (PNP) 50 mA output that is used as a fault indicator.
This output is activated when the received signal strength drops below a critical level. To
use this function, the RSSI indicator must be set to continuously update. This is
accomplished by setting the RP-RSSI PWM Timer to FF in the diagnostics section of the
advanced modem settings tab. See figures 4-7 and 4-8. Figure 4-9 shows the wiring
connections.
