RS-232 Configuration

Setting Dip Switch

Serial RS232 Selection:

• Normal (Default) - This is the standard operating mode and allows for

RS232 pass through.

• Program - This is only for firmware updating the units. For questions on

updating the firmware please contact AVProConnect.

To use RS232 for control signal transmission, connect supplied RS232 cables to

each end of the extenders RS232 ports. This Serial connection will work bi-

directionally as a full featured RS232 extension cable.

NOTE - The "Male" DB9 cable is typically for the display or used with the Rx &

the "Female" is typically from a PC or Control System and used on the Tx.

RS232 Pin-out

For custom RS232 cables the pin-out on the 3.5mm jack for the HDBaseT Tx

and Rx is as follows:

• TIP = RS232 Tx (RS232 OUT/SEND)

• RING = RS232 Rx (RS232 IN/RECEIVE)

• SLEEVE = Ground

Typical RS232 routing requires Rx --> Tx and Tx--> Rx in straight configurations,

meaning you always connect a RS232 Tx to a RS232 Rx (and a Rx to Tx).

UNLESS the configuration is "NULL" or "Crossover" the a Tx will connect to Tx

and Rx to Rx (This is rare.)
