Equinox SST-4I/RJ Hardware Reference Guide 6
The following modular cables are available from Equinox (use with
modular adaptors from table 2 above):
P/N Description
690168 10' 6-wire reversing modular cable
690204 25' 6-wire reversing modular cable
690205 75' 6-wire reversing modular cable
Modular adaptors are available to convert modular jacks to DB-25 or
DB-9 connectors. Table 2 below describes the modular adaptors
available from Equinox. Use a standard reversing 4-wire (data only)
or 6-wire RJ-11 modular cable with these adaptors.
P/N Connector Connects To
210081 DB-25 DCE male terminal or printer (female)
210082 DB-25 DCE female terminal or printer (male)
210083 DB-25 DTE male modem or multiplexer (female)
210084 DB-25 DTE female DCE devices (male)
210085 DB-9 female DB-9 PC (male)
Table 2. Modular Adaptors
The adapters listed in table 2 above, with modular cables as shown
below in table 3 may be used to attach devices to the SST-4I/RJ. The
outer two wires which support control signals are omitted when using
4-wire cables. Standard modular cables used for telephones are
always reversing (e.g., pin 1 is connected to pin 4, etc.) and are
typically 4-wire. If a user supplied modular cable is used, make sure
the cable is reversing (as shown in figure 6 below).
