7.5 Normal Record Mode
Normal Recording mode lets you set the recording speed of the QM. The QM al-
lows you to set the recording speed in three different ways
.
•
Set by External Trigger (usually from the VCR)
•
Set Speed Hour (the recording hour of the timelapse VCR)
•
Set By Field Interval (integral number of pictures between cameras)
This section will discuss the setting of above mentioned speed selection method. To
access the Normal Record mode place the cursor infront of Normal Record Mode in the
main menu and press the “SET” button. The Normal Record mode menu will appears
on the monitor screen.

Set Recording Speed by External or Internal Trigger
Trigger In
The camera switcher or CS pulse output of a VCR triggers when the VCR is record-
ing an image. Some VCRs record the image while their VCR tape is stopped, therefore
the tape moves directly after the pulse is issued. Some VCR record while the tape is
moving. This pulse when supplied to the QM will initiate the unit to go to the next cam-
era in the multiplexer sequence and output to the VCR until the next CS pulse comes in.
If the CS pulse goes away during the process then the QM will continue to play the
image until it receives the pulse. Some VCRs output a CS pulse while in the Time lapse
record mode but when in the real time 2 hour mode this pulse is not available. If the CS
pulse is not recieved by the QM within 30 secs the QM will assume a 2 hour record
speed and switch accordingly.
The following figure show the relationship between the CS Pulse In to video output
of the QM. Figure 12 shows the pin out information from remote control port to the
VCR.
