RS-232/422/485 COM Port Pinouts
The COM 1 Passthrough Port is used to pass control information between VBrick appliances
over the network. The COM 1 port presents a standard DTE interface on an RJ-45
connector. The serial port operates at a default rate of 9.6 Kbps, Async, 8-Bit, No Parity,
Controls = None. On some appliances, the pins on the passthrough port can be set for RS-
232 or RS-422-485 (see below) using the
COM Interface Type parameter on the Passthrough
page in IWS. This option is available on only devices where the Part Number on the Main
Board ends in 3. To determine part number, open IWS and go to
