5.2. Connection with Control System
With the RS232 port, the switchers can be control by several kinds of control systems.
This RS232 communication port is a female 9-pin D connector. The definition of its
pins is as the table below. No. Pin Function

5.3. Connection with Computer
Please connect reference to the following contents.
1) Use a RS232 control line to connect the COM1 or COM2 port of the computer to
the RS232 interface of WVG8A.
2) Install the serial driver.
3) Run the COM software and check the connecting state.
4) If it’s OK, then we can control WVG8A by sending RS232 command codes. If not,
probably the control line is bad contact.

Note:
1) [x1], [x2], [x3] and [x4] are the symbols of input or output channels ranged according
to the model of the matrix switcher. If the symbols exceed the effective range, it
would be taken as a wrong command.
2) In above commands, “[”and “]” are symbols for easy reading and do not need to be
typed in actual operation.
3) Please remember to end the commands with the ending symbols “.” and “;”.
8. Troubleshooting & Maintenance
1) When there is no output images/sounds:
Check if there is any signal at the input.
Check if there is any signal at the output.
We can check these by using an oscilloscope or a multimeter. If there is no signal
input/output, maybe the input/output cables broken or the connectors loosen, please
change for another cable.
Make sure the destination device is exactly on the controlled output channel.
If not the problem mentioned above, probably there is something broken inside the
