Is the KBD300A compatible with the GENEX Multiplexer?
By design the Genex Multiplexer require the KBD4000 or KBD4002 keyboard for direct connection.
The KBD300/KBD300A is not directly compatible with the Genex Multiplexer. The KBD300A will control the Genex Multiplexer when interfaced through either the CM6800 or CM6700 series matrix systems. The Genex Multiplexer requires either the KBD4000 or KBD4002 for keyboard operation.
