CPM-6400 Any-to-Any RS-232 Data Matrix Switch

CPM-6400 Any-to-Any RS-232 Data Matrix Switch


The CPM-6400 matrix switch and data PBX is designed for any RS-232 application where multiple ports need connection to a variety of other RS-232 devices. The unit is ideal for control of multiple RS-232 control or console ports of network control hardware at remote locations for cost-effective out-band management in WAN environments. The unit can also be used in simple RS-232 port contention applications.

CPM-6400 Application Diagram

The CPM-6400 offers individual port parameters and distinct baud rates for each port. Devices connected to the CPM-6400 can communicate regardless of dissimilarities between baud rate, parity, etc. Any port on the CPM-6400 can be connected to any other port for complete matrix connectivity by issuing simple ASCII commands.

The CPM-6400 offers password protection on ports 1 and 2 for remote connection via modem. The unit also shows status display of all connected ports, allows administrators to name each port and even establish hunt-groups. All parameters are stored in battery-backed memory, and the configuration of the switch can also be saved to disk for routine reconfiguration or one-time/event reconfiguration.

The CPM-6400 unit consists of a base unit containing the rack assembly, power supply and control card. 8-Port serial modules are then added to create a data PBX of up to 64 ports. Multiple CPM-6400 units can also be interconnected by dedicating link ports to create a larger switching environment.
