2. Operation
2.1 Record/Play Modes
• If the “PLAY” light is OFF, the multiplexer is in RECORD mode. This mode is used for
recording the camera images onto tape. Make sure that the VCR is also in “RECORD” mode.
• If the “PLAY” light is ON, the multiplexer is in PLAY mode. This mode is used to replay
images from tape. Make sure that the VCR is also in “PLAY” mode.
Press the PLAY key to change mode. To enter PLAY mode, the PLAY key must be pressed for at
least 1 second.
2.2 VCR View Mode
If the “VCR VIEW” light is ON, the multiplexer is in “VCR VIEW” mode.
The “VCR VIEW” mode allows the output of the VCR to be directly viewed. If the VCR and
Multiplexer are both in “RECORD” mode, “VCR VIEW” mode allows the rapidly multiplexed
images to be seen on the Monitor “A”. This provides a confidence check that multiplexing is taking
place and that all cables are correctly connected. It also allows the clock/calendar of the VCR to be
viewed and/or set.
Press the “VCR VIEW” key to change mode.
