TROUBLESHOOTING
If you have difficulty operating your system, run through the following checklist to see if you
can solve the problem.
1. Are the keyboard switches set properly?
2. Is the equipment wired properly?
3. Are the menu options in the multiplexer(s) and server set properly?
4. Has the multiplexer been set to the correct mode using the DISPLAY/RECORD button?
5. The main monitor will display multiple screen images. The spot monitor displays full
screen views only.
6. SPOT MONITOR must be selected to operate presets, patterns, and auxiliaries.
7. Tape playback can be done only on the main monitor while in the VCR mode.
8. Moveable cameras must be Coaxitron® compatible and the proper Coaxitron® format
selected in the Camera menu of the multiplexer. If the proper format is not selected,
the camera will either not move or have sluggish control.
9. Moveable cameras can be operated with the joystick only if the spot monitor is pro-
grammed to track the main monitor or SPOT MONITOR is chosen. The camera will
move on the main monitor if the same camera is being shown on both the main and
spot monitors.
10. The position of switch 7 on the keyboard determines how you call cameras.
If the switch is ON, all cameras are addressed consecutively. Do not count just the
cameras installed. Count 16 camera inputs per multiplexer, even if a multiplexer has only
9 inputs. The first input of multiplexer 1 is always camera 1, the first input of multi-
plexer 2 is always camera 17, the second input of multiplexer 3 is always camera 34.
If the switch is OFF, cameras are addressed in groups of 9 or 16 according to the
address of the multiplexer. Select a multiplexer (for example, number 3), then choose
a camera (1-9 or 1-16).
11. If you have one multiplexer, it must be the master. If you have more than one
multiplexer, one of them (any one) must be the master and all the others slaves
(Advanced System Setup menu of multiplexer).
12. If you have more than one multiplexer, they must have different addresses (Advanced
System Setup menu of multiplexer).
13. If you have a server, the address of the multiplexer must correspond to the input it is
connected to on the server. For example, if the multiplexer goes to input 4 on the
server, the multiplexer must be address 4.
14. If you have a server, each keyboard must have its own address.
15. If you have a server, each keyboard controls its corresponding monitor(s). In the
SINGLE mode, keyboard 1 controls monitor 1, keyboard 2 controls monitor 2, etc. In
the PAIRED mode, keyboard 1 controls monitor 1 (main) and monitor 2 (spot), and
keyboard 3 controls monitor 3 (main) and monitor 4 (spot). In the paired mode,
keyboards 2 and 4 are not used.
16. If you have a server and cannot change between full screen and multiple screen views
on the main monitor, check the MAIN MONITOR CONTROL setting in the Monitor
menu of the server.
17. Adjust head tracking control on the VCR until the picture stabilizes if:
a. the picture appears jittery when multiplexer is in VCR playback mode, or
b. one camera view sequences out of order when the multiplexer is in multi-screen
VCR playback mode.
