attach a remote keyboard to your system. The American Dynamics MegaPower LT

See the MegaPower LT Installation and Operation Handbook for more details.

MENU ITEM DESCRIPTION
RS-485 Unit
Address
Allows you to change the RS-485 ID address of the DigiMux unit.
The ID is in the range of 1
to 254. The default ID is 9.
NOTE: In general, no two devices on the same RS-485 bus
should have the same ID address. Make sure device ID
assignments are unique.
If you are daisy-chaining DigiMux units, each unit must have a
unique RS-485 ID address. For example, if you daisy-chain five
units, the RS-485 ID address assignments can be 9, 10, 11, 12,
and
13.
