2.3 Multiplexer Control

Duplex setup:

NOTE: Multiplexers require a new ROM version to be controlled by the keyboard controller. The new multiplexer ROM accepts control instructions from the keyboard controller. If your multiplexer’s serial number is M104xxxx or higher, then it is ready to accept control instructions. Alternately, you can check the status of your multiplexer by pressing the Menu key of the multiplexer and then selecting item 9. If you see the “** Protocol” option line in the Communication Setup menu, your multiplexer has the new ROM, and you do not need to replace the ROM. If your multiplexer has the old ROM version, contact your distributor on how to get new a ROM.

CAUTION: Before opening the multiplexer, make certain you are working on an antistatic work surface and that you are wearing a grounding wrist strap. Also, be very careful to orient the ROM chip correctly and not bend any of the pins.

NOTE: Replace the multiplexer firmware with the new multiplexer ROM (U45) as follows;

Remove the top cover of the multiplexer, and locate the ROM (U45). Before removing the ROM, note the orientation of the ROM. After removing the old ROM from the socket, insert the new ROM.

Be careful to orient the new ROM the same as the old ROM. (Refer to the Multiplexer instruction manual.)

Set the multiplexer functions as follows:

(Press the Menu key of the multiplexer to enter the Unit Options menu.)

** The old ROM version does not show Protocol selection option.

Multiplexer alarm inputs will function normally, but the Dome controller has no way of knowing about alarms wired to the Multiplexer. If a Dome preset is required for such an alarm, you must connect the same alarm input to both the multiplexer and Dome.
