2.For proper recording, the switching rate of the multiplexer between cameras must match that of the VCR. There are two ways to do this:

a.One way is with a head switching pulse from the VCR. This is the most reliable way to synchronize the multiplexer and VCR. The pulse from the VCR tells the multiplexer how fast to switch between cameras. To use this method, connect the head switching pulse output from the VCR to the HS (head switching) connection on the multiplexer. Refer to Figure 6. The six-pin plug-in terminal block may be pulled out of the connector on the back of the multiplexer to facilitate ease of wiring.

b.If a head switching pulse from the VCR is not available, you can synchronize the VCR and multiplexer by programming the multiplexer switching rate to match the recording speed of the VCR. This will be done in the Programming section, after you have finished installing your multiplexer. No wiring is required if you use this method.
