RS232 Connections in a Multi-Matrix System
Keyboard and Port Expander Connection
Keyboards can be connected to any RS232 port in a multi-matrix system. Therefore, in a Mode 3 configuration with six
secondary matrices, up to 56 keyboards can be connected (without using port expanders). Any of these keyboards can
be used to control any component in the system—keyboards connected to a secondary matrix are NOT limited to
control of components connected to the same secondary matrix.
