AT-OME-ST31

Advanced Operation

In control mode, RS-232 commands are sent from a computer or control system (DTE) to the AT-OME-ST31 (DCE).

This method allows direct control of the matrix for routing, IP configuration, powering-on / powering-off and other

functions.

AT-OME-ST31

Connect the RS-232 cable between the control system and the AT-OME-ST31. Refer to

Cable Assembly (page

51)

for instructions on preparing the cable.

Set the baud rate of the computer/control system to 115200. If the control system is not set to this baud rate,

then the AT-OME-ST31 will not respond to RS-232 commands.

3. Refer to the

Applications Programming Interface

for a listing of available commands.

NOTE:

The

RS-232

port on the AT-OME-ST31 runs at a baud rate of 115200. The control unit must

be set to the same baud rate, in order to communicate with the AT-OME-ST31.
