Multiple Keyboards on an RS485 Network
A maximum of 16 devices may be connected when working in RS485 mode. A maximum of eight keyboards can be assigned to the system.
For correct connection of multiple keyboards to an MegaPower LT, please see the MegaPower LT Installation and Operation Handbook.
Terminating/Biasing the RS485 Network
The keyboard has built in RS485 network termination and/or biasing. For most small to medium sized installations, it should not be necessary to change the switches from their default settings. Only for large installations should your network require biasing and/or terminating. The switches are shown below for your reference. The default setting for switches 1, 2 and 3 is OFF (UP). Switch 4 is not used.
