Patton electronic 1020 Connection to the RS-232 Interface, Operating the Model, Specifications

10.BEND the top half of the case as necessary to place it over the strain relief assembly. Do not snap the case together yet.

11.Insert one captive screw through a saddle washer and then insert the entire piece through the hole in the DB-25 end of the case. Snap that side of the case closed. Repeat the process for the other side. This completes cable installation.

4.2CONNECTION TO THE RS-232 INTERFACE

Once you have connected the twisted pair wires correctly, simply plug the Model 1020 directly into the DB-25 port of the RS-232 device. After doing so, remember to insert and tighten the two captive connector screws.

(Note: If you must use a cable to connect the Model 1020 to the RS-232 device, make sure it is a straight through cable of the shortest possible length—we recommend 6 feet or less).

4.3 OPERATING THE MODEL 1020

Once the Model 1020 is properly configured and installed, it should operate transparently—as if it were a standard cable connection. Operating power is derived from the RS-232 data and control signals; there is no “ON/OFF” switch. All data signals from the RS-232 interface are passed straight through. All control signals from the RS-232 interface are looped back.

NOTE: If your system requires hardware flow control, you will need the Patton Model 1030 or Model 1070 Short Range Modem. Call Patton Customer Service at 301-975-1007 for more information.
