Drawing 3-5:
IPn4G Rear View
The
DATA (RS232 Port (COM0))
on the rear
of the circuit board is used for:
RS232 serial data (300-921kbps)
The
RS422/485 Port
is used to interface the IPn4G to a DTE
with the same interface type. Either the RS232 or RS422/485
interface can be used for data traffic, not both.
Vin+/Vin
–
is used to power the unit. The input Voltage range is
9-30 Vdc.
Digital I/O
–
The IPn4G has 1 input / 1 output. Inputs have a small wetting
current (Vin) used to detect a contact closure, and prevent false readings by
any noise or intermittent signals, it has a threshold sensitivity of 1.8V.
Maximum recommended load for the output pin is 150mA @ 30 Vdc (Vin).
PoE
–
The IPn4G can also be powered using Passive PoE on the Ethernet
Port, via a PoE injector.
3.1.2 Connectors and Indicators
3.1.2.2 Rear
On the back of the IPn4G is the Data (COM0) port, RS485/422 interface, as well as the power connections.
The unit also has the SMA(F) connectors for the Main (TX/RX), the Diversity (RX) antenna’s, and a RP-
SMA Female connector for the optional WiFi antenna.
