Connecting the Mounting Brackets
If you have a mounting rack you can use the mounting brackets to mount the matrix switch.
There is a left side bracket and a right side bracket. Please do the following to assemble:
1. Unscrew the two side screws on each side of the Matrix Switch.
2. Unpack the screws from the bag, and identify the smaller screws.
3. Place the mounting brackets on the side of the Matrix Switch so that the two larger holes
on the brackets are aligned with the front of the Matrix Switch, and screw the smaller
screws that were included in the pack on the side of the switch.
4. Using the larger screws that are included in the pack, mount the brackets on your
mounting rack.
RS-232 Control
The Matrix Switch can be controlled by sending command from PC or other equipment. PC and
other equipment can also get the status of the Matrix Switch from the RS-232. Connection
between the Matrix Switch and a PC should be done using a null modem DB9 cable no longer
than 15 meters (50 ft.)
