  • The C422, or Communication Converter is an RS232-to-RS422 interface converter. C422 conforms to RS422 standard and configures for four wire full duplex operation. The C422 is typically used to interface to "INTELLIGENCE" NetMaster or a host computer, such as an IBM PC, IBM PS/2 or compatible to "INTELLIGENCE" field control modules via an IntellNet Bus which is configured for RS422 operation.
    C422 contains four RS422 ports. Each port can be networked IntellNet field controllers up to 32 units.
