Drawing 3-5: IPnXGii Rear View
The Console (RS232 –Tx/Rx) on the rear of the unit is used for:
AT Command Interface
RS232 serial data (TX, RX)
The RS422/485 Port is a standalone port that can be used in addition to the RS232 Data Port.
Programmable I/O– The IPnXGii has 8 programmable Analog/Digital Inputs or 8x Digital Outputs.
Maximum recommended load for the output pin is 150mA @ 30 Vdc (Vin).
Vin+/Vin– is used to power the unit. The input Voltage range is 9-30 Vdc.
PoE– The IPnXGii can also be powered using Passive PoE on the Ethernet
Port (WAN), via a PoE injector.
