Model 2604 T1/E1 DACS Getting Started Guide
28
Completing the hardware installation
1. Refer to figure 12 for the T1/E1 RJ-48C pinout diagram.
Figure 12. T1/E1 RJ-48C pinout diagram
2. Attach the network cable from the telephone network demarc to the Primary T1/E1 port (RJ-48C) on the
DACS.
Note
For 75-ohm twin-coax E1 connections, use the Patton Model 460 E1
120-ohm/75-ohm balun to convert from a 75-ohm dual-coax (from
the telco) to the 120-ohm twisted-pair interface the DACS uses.
Completing the hardware installation
This section verifies that the DACS hardware is operational to the point where you can begin configuring the
software settings. If you have an AC unit, go to step 1 in the following procedure. Otherwise, for DC units, go
to step 4.
1. Verify that the AC power cord included with your DACS is compatible with local standards. If it is not,
refer to Chapter 6, “Contacting PATTON for assistance” to find out how to replace it with a compatible
power cord.
2. Connect the male end of the power cord to an appropriate power outlet.
3. Verify that the green POWER LED is lit. If the POWER LED is flashing
green
, refer to Chapter 5, “Trou-
bleshooting and maintenance”. Otherwise, hardware installation is complete. Refer to Chapter 3, “Config-
uring the DACS for operation”.
4. Connect the equipment to a 40–72 VDC, 1A supply source that is electrically isolated from the AC source
as stated below.
The DACS power supply automatically adjusts to accept an input
voltage from 100 to 240 VAC (50/60 Hz, 2A).
Verify that the proper voltage is present before plugging the
power cord into the receptacle. Failure to do so could result in
equipment damage.
An approved external SELV power supply that incorporates a
disconnect device must be used and positioned within easy
reach of the operator’s position.
