Model VSM-404

3.7 Control from Serial Devices (RS-232 Command Protocol)

To control the Video Matrix Switch through an attached PC or other serial

device, the serial device has to be able to communicate with the Switch.

(You’ll need to set the device to 1200 bps, 8 data bits, and no parity; the

number of stop bits is irrelevant.).

To tie the unit to a PC, use a DB9 F/F cross-over cable (Null Modem:

2<>3, 4<>6, 7<>8, 5=5).

The serial device will have to mimic the Switch’s keypad commands.

When you press a button on the keypad, a “make” code is sent to the

Switch; when you release a button, a “break” code is sent to the Switch.

Here are the values you need to send to the Switch to get it to change

channels, listed as both ASCII characters and hexadecimal values:

Make Code Break Code Keypad
