Making a Test Tape
The easiest way to verify multiplexer system operation is to make
a test recording and play it back. This process effectively 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 proce-
dures. 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 (116) 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.
