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 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 the cable installation
process.
3.2 CONNECTION TO THE RS-232 INTERFACE
The Model 1009 is configured as a DCE, and is designed to
connect to the DB-9 serial port of an RS-232 DTE (PC, laptop, host).
If you must use a cable to connect the Model 1009 to the DTE device,
make sure that it is a
straight through cable of the shortest possible
length—we recommend 6 ft or less (See Appendix C).
Should you wish to connect a DTE to a DCE using short range
modems (ex. a PC/AT connecting to a multiplexer several hundred feet
away), we recommend using a Model 1009 for the DB-9 DTE
connection and a Patton Model 1000 for the DB-25 DCE connection.
These two short hauls
are compatible. If you need to use a Model 1009
on both ends, connection to the DCE device will require a
cross over
RS-232 cable. Call Patton Technical Support at (301) 975-1007 for
more details.
3.3 OPERATING THE MODEL 1009
Once the Model 1009 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 from the RS-232 interface, including
X-ON/X-OFF flow control information, is passed straight through. Any
hardware flow control signals are looped back at the interface and are
not passed between the short hauls.
