the CCU updates all other controllers with the same monitor
selected to reflect the camera change.
For example:
JPD-100 Controller #1 has camera #1 and monitor #4 selected
on the top line of the LCD display:
CNTL - CAM 1 MON 4
JPD-100 Controller #3 has camera #1 and monitor #4 on the
display:
CNTL - CAM 1 MON 4
The operator on JPD-100 Controller #1 calls up camera #3:
CNTL - CAM 3 MON 4
The CCU sends the control camera change to all the
controllers with control monitor 4.
CNTL - CAM 3 MON 4
If a MultiCall is activated from anywhere in the system that calls
a control camera displayed on one of the JPD-100s in the
system; the JPD-100(s) loses control of the camera. To regain
control of the camera displayed on the JPD-100, press CNTL
on the JPD-100 keypad.
