Appendix B — Connector Pinouts
Connections from the Equinox card on the MAP to the hospitality adjuncts ( PMS
or call accounting) can often cause problems. The following list g ives you the
pinouts and EIA leads provided when using a D6AP modular cord from the
Equinox card to the Equinox 10/10 adapter (P/N:210068, comcode 406983 155).
These pinouts are on the 25-pin end of the adapter.
■Pin 2 - TD (transmit data)
■Pin 3 - RD (receive data)
■Pin 7 - GND (ground)
■Pin 8 - DCD (data carrier detect)
■Pin 20 - DTR (data terminal ready).
This arrangement of EIA is standard in the industry, but these pinouts may
become valuable if the adjunct vendor needs to provide a special adapter to
interface to this arrangement.
