3.5 RS232/RS485/RS422 plus IRIG-B via RJ45

Each port is individually selectable via software to be RS232, RS485 or RS422. IRIG-B

signal and ground are available on pins 2 and 3, respectively, for every mode. The RJ45

port and pin-out is shown below.

NOTES:

1. No internal termination is provided.

2. Pins 7 and 8 are connected internally. In RS232 mode, these pins enter a high impedance state. A DTE

that asserts RTS will see CTS asserted, although the RuggedServer will not perform hardware flow

control.

3. In RS232 mode, the RJ45 ports conform mostly to EIA-561 DTE, which transmit on TXD and receive on

RXD.

The IRIG-B output on each port is configurable via software to provide IRIG-B pulse-

width modulated output (IRIG-B006 or IRIG-B007) or PPS output, a single pulse per

second on the second.
