CHECK THESE THINGS

2A

MULTIPLEXER

Below are the minimum things to check.

1. If you have more than one multiplexer, each one must have its own address (UNIT ID
in the Advanced System Setup menu). If you have a server, the multiplexer address
must match the input on the server to which it is connected. For example, if the
multiplexer is connected to input 3 on the server, set the multiplexer address to 3.

2. Set the master/slave designation to let the keyboard communicate with multiplexers.

• In polled mode (switch 4 OFF), you must designate one multiplexer (any one) as

the master and all the others as slaves. If you have just one multiplexer, it must
be the master.

• In non-polled communication mode (switch 4 ON), all multiplexers must be

slaves (the keyboard is the master).

Set the address and master/slave designation from the front panel of the
multiplexer, not from the keyboard. For instructions, refer to

Multiplexer with the Keyboard

2B

MULTIPLEXER SERVER

Below is the minimum you should check.

If you intend to control two monitors from one keyboard (paired mode), you must change
the settings for the monitors (Monitor menu). Programming the server can only be done
from the keyboard. Refer to the server manual for instructions.

Duplex Color Multiplexer

This section applies only to programming the multiplexer. The multiplexer can be
programmed from the keyboard or from the multiplexer’s front panel. To program the
multiplexer from the front panel, refer to the multiplexer manual. To program the
multiplexer server, refer to the server manual.

Programming lets you configure the multiplexer (from the KBD4000) for the way you want your
system to operate. The multiplexer automatically selects the most common operating param­eters. However, some minimal programming may be required to make your system work.

Programming of system, camera, and VCR setup; camera sequencing; and alarm and
activity detection is done through on-screen menus displayed on the main monitor. You can
enable a password to prevent unauthorized access to the menus.

Programming of the picture-in-picture, and 4-, 9-, and 16-camera displays can be done
