RS232 port
All UltraMatrix switches are equipped with an RS232 serial port on each installed CPU slot. These ports on all UltraMatrix models are RJ12, 6-conductor connectors. They provide a serial interface to the UltraMatrix from a computer terminal, a standalone computer or a Notebook computer that is not connected to a CPU port on the Unit. The RS232 serial port enables you to:
Upgrade the system firmware
Restore a Unit to its factory default settings
Configure an expansion switch
Switch a KVM station to a CPU port
An adapter and serial cable are provided for serial interface. Firmware cannot be updated from a computer terminal.
