TWISTED PAIR CONNECTION USING MODULAR JACKS
The modular version of the Model 2017A has an RJ-11 or RJ-45
jack mounted in the case. These jacks are prewired for a standard
TELCO wiring environment. To be sure you have the right wiring, use
the table below as a guide.

4.2. COMPLETING THE INSTALLATION
Once you have configured the unit for DTE or DCE and connected
the twisted pair wires correctly, simply plug the Model 2017A into the
RS-232 data port. Remember to insert and tighten the two captive
connector screws.
The Model 2017A requires 9 volts of DC power (with a trans-
former, it will work with either 110V or 220V). To order the power sup-
ply, call Patton Electronics Customer Service at (301) 975-1000.
