VM600 CPU M | 200-595-045-114 VIBRO METER CPU card

The CPUM is a modular CPU (central processing unit) card that acts as “rack controller” in a networked VM600 system. Depending on system requirements, the CPUM can be used either alone in the rack (installed in the front card cage) or in conjunction with the associated IOCN input/output card (installed in slot 0 of the rear card cage, directly behind the CPUM).The CPUM card consists of a carrier board with two PC/104 type slots that can accept different PC/104 modules: a CPU module and an optional serial communications module.All CPUM cards are fitted with a CPU module that supports two Ethernet connections (primary and secondary) and two serial connections (primary and secondary). That is, both the Ethernet redundant and serial redundant versions of the card.Optionally, a CPUM card can be fitted with a serial communications module (in addition to the CPU module) in order to support additional serial connections. This is the serial redundant version of the card.The CPUM card with the optional serial communications module provides:• RS-485 (115.2 kbps) communications as either half-duplex (2-wire) or full-duplex (4-wire) via the ‘A’ and ‘B’ connectors (6P6C (RJ11/RJ25)) on the IOCN card’s panel.
