EMERSON PMC-HS Serial Module

EMERSON PMC-HS Serial Module

Application Information

The PMC-HS Serial provides four channels of high-speed serial data communications channels on a singlewide PMC module. It can be used in many data communications, LAN/WAN networking and telecommunications applications. A maximum data rate of 10 Mbit/sec is supported for synchronous protocols utilizing an external. clock. Up to 2 Mbit/sec is supported for asynchronous protocols, with popular baud rates of up to 921.6K baud available using the standard 14.7456MHz oscillator in RS-422 interface mode. Each of the four channels is fully programmable to support many high performance serial communications protocols, such as asynchronous, monosync, bisync, HDLC, SDLC, LAPB, LAPD, ISDN, and PPP.

The PMC-HS Serial supports a wide selection of physical interfaces, configurable by software alone. Channels can be individually selected as RS-232, RS-422, EIA-449, EIA-530, or V.35. No hardware re-configuration is required. Seven signal pairs for each channel are available at the rear-panel P4 connector and the front panel I/O connector. An optional transition cable is available to interface the 68-pin front panel I/O connector to four DB25s.
