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
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.)
