RUNNING PROGRAM 

(cont...)

SERIAL CABLE

MATRIX ROUTING is accomplished by first entering the output bank required. The command line
will ask for a selection of an input for that output. Enter the input you require and the next line will
ask for  an enable Y/N. Enter your choice and the route is executed. At the same time the CON-
NECTED OUTPUT register will show the connection. Repeat this operation for all four outputs.

At the command line, you can also enter MUTE mode. This will mute only the output selected. You
may also QUIT the program from any of the prompt lines. Exiting the program leaves the switcher in
the last controlled mode. Pressing the front panel switches or enabling the RS232 port again will
change the settings.

PORT ASSIGNMENTS: The software is configured to boot on COM1. However, it can be assigned
to andy COM PORT 1-4. To change a port assignment: At C:\4x4232 type AV [-p] where p is the
new port number. Example: AV [-2] will boot the program on COM2.

To connect your PC to the OMX-4X4, a straight 9-Pin Female to 9-Pin Female cable can be used. The
pinout is direct pin-to-pin. The cable can be up to 100’ long. Ribbon cables can be used for cable
lengths up to 30 feet. It is recommended that shielded cable is used for longer length runs.
