Wire COMM ports

Wire the XFC G5 or XRC
communication depends on the type of serial interface required by the device. Wiring for power is
required if there is no external supply powering the external device.
Install the required communication modules in the correct slot on the XFC
IMPORTANT NOTE: Refer to the XFC
detailed wiring for specific external devices.
External devices can be powered from the (VBAT) or (SW VBAT) pins on the XFC
ports.
The output voltage at these pins is dependent upon the external power supply connected to the CHRG
connector (J5 on XFC G5
(The XFC G5 and XRC G5
NOTICE – Equipment damage or loss of data. Before connecting an external device to
VBAT or SW BAT, ensure that the device is compatible with the voltage range. Connecting an
incompatible device may result in damage to the device.
COMM 1 and COMM 2 connect XSeries
