1.3 Receiving Data
The EDH4 transponder can receive analog power supply data through its PWR SUPPLY port and battery
data through its two battery ports (BAT A/B and BAT C/D). It can receive HMS power supply data through
its HMS interface port (rear panel) and can simultaneously directly measure and report battery voltages
through its two battery ports (BAT A/B and BAT C/D). The transponder uses the direct battery connection
when configured to receive battery data through both the HMS interface port and a direct battery
connection.
