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 gives 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 406983155).
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.
