4.2  INSTALLING THE MODEL 1080ARC INTO THE CHASSIS

The Model 1080ARC is comprised of a front card and a rear card.  The 
two cards meet inside the rack chassis and plug into each other by way 
of mating 50 pin card edge connectors.  Use the following steps as a 
guideline for installing each Model 1080ARC into the rack chassis:

   1. Slide the rear card into the back of the chassis along the metal rails 

provided.

   2. Secure the rear card using the metal screws provided.

   3. Slide the card into the front of the chassis.  It should meet the rear 

card when it’s almost all the way into the chassis.

   4. Push the front card gently into the card-edge receptacle of the rear 

card.  It should “click” into place.

   5. Secure the front card using the thumb screws. 

Since the Model 1000R16P chassis allows “hot swapping” of 

cards, it is not necessary to power down the rack when you 
install or remove a Model 1080ARC.

4.3  WIRING THE MODEL 1080ARC

Each of the rear interface cards compatible with the Model 1080ARC has 
one RS-232 port and one 4-wire (twisted pair) port.  These cards provide 
a female DB-25 for RS-232 connection.

The Model 1080ARC uses a DB-25 female to connect the RS-232 inter-
face to your computing hardware.  It  is pinned according to the RS-
232C/V.24 interface standard.  For specific interface pin-outs, please 
refer to the diagrams in Appendix D on page 37 of this manual.

The Model 1080ARC is wired to connect to a DTE.  If your RS-232 out-
put device is a DTE, use a straight though cable to connect to the Model 
1080ARC.  If your RS-232 output device is DCE, call Technical Support 
at (301) 975-1007 for specific installation instructions.

The Model 1080ARC operates over one or two twisted pair.  In all appli-
cations, the twisted pair wire must be 26 AWG or thicker, unconditioned, 
dry, metallic wire.  Both shielded and unshielded wire yield favorable 
results.
