2.3 RS-232 Communications
V2125 keyboard can establish bi-directional RS-232
communications with Infinova series matrix switching systems
(V2011, V2015, V2020, V2040, V2060, V2070, and V2080). Here
is just an example to show RS-232 communications with V2011
matrix switch systems.

2.5 Using Port Expanders
In some applications, V2405A-4 series Port Expanders might be
required to expand the original RS-232 ports of the matrix switching
system.
A single port expander can expand one original port into a
maximum of four ports. Different matrix switching systems identify
the expanded ports with different approaches.
For details on how your matrix switching system will recognize the
expanded ports, please refer to manuals provided with the matrix
switching system and the port expander.
