Making a Test Tape
The easiest way to verify multiplexer system operation is to
make a test recording and play it back. This process effec-
tively tests every piece of equipment in the system.
Before proceeding with the test tape, it is recommended that
you complete both the monitor calibration and camera check
procedures. Make certain that the multiplexer monitor and
all system cameras are correctly adjusted. Doing so will help
to ensure the best results during the tape test.
The tape test procedure is as follows:
1. Place the VCR in the record mode at the 24-hour speed
(this is the multiplexer default VCR record speed and can
be changed). The VCR begins recording multiplexed
camera video. You may select any viewing mode or
display format while recording. Doing so will not affect
the tape since camera recording and display are completely
independent multiplexer functions.
2. After several minutes, stop the VCR and rewind the tape.
3. Place the VCR in the play mode.
4. Press the tape button on the multiplexer.
When the multiplexer detects the encoded VCR signal, it
configures itself for tape playback and displays all recorded
cameras in the multicamera format. To view one camera full
screen, press the corresponding camera (1–16) button. To
view multiple cameras, press the desired display format (PIP,
2x2, 3x3 or 4x4) button. If the camera or cameras do not
appear, check VCR operation and review all video connections.
This completes the tape test. If it is not successful, repeat the
steps outlined above. If you continue to have difficulties, turn
to Appendix C — In Case of Trouble for assistance.
