Switching the Power Supply On and Off
The power switch is located on the front panel. When plugged in
and switched on, a red front panel LED will glow. Since the Model
1000R16P is a "hot swappable" rack,
it is not necessary for any cards
to be installed before switching on the power supply. The power supply
may be switched off at any time without harming the installed cards.
4.2 INSTALLING THE MODEL 2065/66RC INTO THE CHASSIS
The Model 2065/66RC is comprised of a front Function card and a
rear Interface card. The two cards connect in the rack chassis via
mating 50 pin card edge connectors. Use the following steps as a
guideline for installing each Model 2065/66RC into the Model
1000R16P rack chassis:
1.
Slide the rear Interface card into the back of the chassis along the
metal rails.
2.
Secure the rear card using the metal screws provided.
3.
Slide the Function 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 spring loaded thumb screws.
Note: 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 2065/66RC.

4.3 DCE/DTE CONNECTION
The Model 2065/66RC rear card has two UD-26 connectors,
labeled “A1” and “B1” (see figure 7, below). Port A1 connects to the
RS-232 device (Model 2065RC) or the V.35 device (Model 2066RC).
Port B1 connects to the X.21 device in all cases. Port A1 may be
configured as either a DCE or DTE. Port B1 is always configured
as a DTE.
To connect computing devices to ports A1 and B1 on the Model
2065/2066RC, follow these instructions:
1. Configure the Model 2065/2066RC for your specific application
according to the instructions in Section 3.0 of this manual.
2. Connect computing devices to the Model 2065/2066RC using
multipair adapter cables (see Appendix B for a list of custom
adapter cables available from Patton Electronics). In all cases, the
X.21 DCE must supply the system timing, and the RS-232/V.35
device must accept external clock. The wiring of your adapter
cables should support this requirement.

Notice!
Any terminal cable connected to the Model
2065/66RC must be shielded cable, and the outer shield
must be 360 degree bonded–at both ends–to a metal or
metalized backshell.
