Switching the Power Supply On and Off

The power supply on/off switch is located on the front panel. When

plugged in and switched on, a red front panel LED will glow. Since the
Model 1000R16 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.

NOTE:

Please refer to the Model 1000RP Series User Manual

and DC Rack Mount Power Supplies for fuse and power card
replacement information.

4.2 INSTALLING THE MODEL 1060RC INTO THE CHASSIS

The Model 1060RC is comprised of a front "brains" card and a rear

"connections" 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 1060RC
into the Model 1000R16 rack chassis:

1. Slide the rear "connections" 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 "brains" 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.

Secure the front card using the thumb screws.

NOTE:

Since the Model 1000R16 chassis allows "hot swapping"

of cards, it is

not necessary to power down the rack when you

install or remove a Model 1060RC.

4.3 RS-232 CONNECTION

The Model 1060RC offers two port options for connecting the

RS-232 interface to your computing hardware: DB-25 female and
10-pin RJ-45 female (the RS-232 port is always the

lower port on the

interface card). The DB-25 is pinned according to the RS-232C/V.24
interface standard. The 10-pin RJ-45 is pinned according to the
EIA/TIA-561 interface standard. For specific interface pin-outs, please
refer to the diagrams in Appendix D of this manual.

The Model 1060RC is wired to connect to a DTE. If your RS-232

output device is a DTE, use a

straight though cable to connect to the

Model 1060RC. If your RS-232 output device is DCE, call Patton
Technical Support at (301) 975-1007 for specific installation
instructions.

4.4 TWISTED PAIR CONNECTION

The Model 1060RC operates over two twisted pair. In

all

applications, the twisted pair wire must be 26 AWG or thicker,
unconditioned, dry, metallic wire. Both shielded and unshielded wire
yield favorable results.

Note:

The Model 1060RC can only

communicate in a closed data circuit with another Model 1060RC. Dial-
up analog circuits, such as those used with a standard Hayes-type
modem, are

not acceptable. For further information about acceptable

wire grades, please refer to the diagrams in Appendix B.

4.4.1 Point-to-Point Twisted Pair Connection

The 6-position RJ-11 and 8-position RJ-45 jack options for the

Model 1060RC (always the

upper jack on the rear interface card) are

prewired for a standard TELCO wiring environment. Connection of a
4-wire twisted pair circuit between two or more Model 1060RCs
requires a

crossover cable as shown in the figures below and on the

following page.
