2.4.1.2 Auxiliary RS-232 Control Port
The matrix switches without IP control have a secondary serial port that can work
independently of the primary port. The user can control the matrix from either or
both ports.
The auxiliary RS-232 connector is an RJ45. Make sure to not connect this to any
LAN devices. The pinout for the auxiliary RS-232 follows the basic EIA-561 for
TX RX and Ground. Optional current limited 12v DC may also be provided (max
rated output current of 50 maDC) that can be used to power external keypads or
control devices, please contact Hall Research if you need to draw power from this
connector.
Caution High-Voltage

Opening the unit also voids the warranty on the unit.
The pinout is shown below.
