independently through a monitor.
5. Ensure that video devices are plugged into correct inputs of VS4X1.
Test by programming for 1 sec interval and 4 inputs (switches 6, 7, 8 ON).
Check switch 7 and 8 programming for correct number of inputs.
6. Reconnect devices to desired input number.
Recommended Action
1. Disconnect and reconnect power supply. At least one Input and one
Output LED should be on or flashing. Make sure all other connections are
secure.
2. Arrange devices to the correct input and Output connections.
3. Check Output LED, if it is flashing then it is disabled. Press the Output
