OVERVIEW
The LPM/MCM-7312 (LPM/MCM-7314) is a STD Bus and CMOS STD Bus compatible, two channel, RS-232-C input/output board, designed to be a multiprotocol asynchronous or synchronous serial communications board based upon the Z85C30 CMOS SCC. Each serial channel is independent from the other and capable of data rates of up to 19.2K baud asynchronous or 307.2K baud synchronous.
The MCM prefix on the card designates a standard STD Bus board. The LPM prefix designates a CMOS STD Bus board. A MCM/LPM prefix indicates the card has the same features and functionality and is available in both CMOS and regular NMOS/TTL logic. The differences between these two are the power requirements and operational temperature range.
