11. Insert one captive screw through a saddle washer, then insert
the captive screw with the washer on it 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.
4.2 CONNECTION TO THE RS-232 INTERFACE
Once you have configured the Model 1010B for DTE or DCE and
connected the twisted pair wires correctly, all that remains is to plug the
1010B 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 1010B 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 1010B
Once the Model 1010B is properly 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 1012 Modem or Model 1060 Short Range
Modem. Call Patton Technical Services at: (301) 975-1007;
