3. Operation
3.1 Keyboard Lock/Unlock
When the user leaves the control desk, he may wish to lock the keyboard controller to prevent unauthorized use.
Pressing 777 + ENTR will lock the keyboard controller. Pressing 777 + ENTR while the keyboard is locked will open the password screen. If the correct
password is entered, the keyboard controller will return to normal operation.
If the power is turned off and on while the keyboard is locked, it will ask for the password. Entering the correct password will cause the keyboard controller
to return to normal operation.
NOTE: If you forget your own passwords, turn off the keyboard controller, contact your distributor to get a 4-digit back door password.
This will change the passwords to the factory default. Contact your distributor to get the 4-digit back door password.
3.2 Selecting Camera & Mux Control
3.2.1 Duplex/Simplex 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.)
Press the MENU key of the multiplexer to enter the Unit Options using and SET key of mux.

Multiplexer alarm inputs will function normally, but the KBD 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 the Dome Camera.
