Admonishments
Important safety admonishments are used throughout this publication to warn of possible
hazards to persons or equipment. An admonishment identifies a possible hazard and then
explains what may happen if the hazard is not avoided. The admonishments — in the form of
Dangers, Warnings, and Cautions — must be followed at all times. These warnings are
flagged by use of the triangular alert icon (seen below), and are listed in descending order of
severity of injury or damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.

1 DESCRIPTION
This section describes the DRU, the various DRU antennas, and the AC/DC power converter
(optional accessory item).
1.1 Digital Remote Unit
The DRU, shown in Figure 1, serves as the cellular user servicing unit for the Digivance ICS.
The DRU consists of an electronic circuit board assembly that is mounted within a powdercoated sheet metal enclosure. The electronic circuit board assembly is not user replaceable.
The DRU is designed for use within a non-condensing indoor environment such as inside a
building. All controls, indicators, and connectors (except the antenna connector) are mounted
on the DRU front panel for convenient access.

Figure 1. Digital Remote Unit
The DRU is equipped with four integral mounting feet that allow it to be mounted on any flat
horizontal or vertical surface. A typical location for mounting the DRU would be above
ceiling tiles where the optical fiber and power cables can be concealed or on a wall. Slots are
provided in the mounting feet for securing the DRU to the mounting surface.
The RF signal interface between the DRU and the cellular users is provided through an
external antenna connected to a female SMA connector. The antenna may be ordered
separately from ADC. Several types of antennas with various patterns are available. Non-ADC
antennas may also be used with the DRU to meet various application requirements.
The DRU is equipped with a small form factor LC type optical transceiver that provides a
point for connecting the optical link cables. Depending on the application requirements, the
optical transceiver may be connected to either a DHU or a DEU.

ADCP-75-112 • Issue 2A • June 2001
The DRU is equipped with a female RJ-45 jack that provides a point for connecting a DC
power cable. The DRU is powered by 34–48 Vdc power which is supplied through the RJ-45
connector. Power to the DRU may be supplied by the DHU, DEU, or by a 120 Vac to 48 Vdc
power converter (available separately as an accessory item) plugged into a properly grounded
120 Vac outlet. The AC/DC converter is a UL Listed stand alone Limited Power Supply (LPS)
unit with a rated output of 48 Vdc at 1.2 A. When powered by the DHU or DEU, a category 3
or 5 twisted-pair cable terminated with RJ-45 connectors is required. The recommended
maximum length of the power cable is 500 meters (1,641 feet). Any distance beyond 500
meters requires powering by the AC/DC converter.
The DRU user interface consists of the connectors and the LED that are provided on the DRU
front and rear panels. The DRU user interface points are indicated in Figure 2 and described in
Table 1.

1.2 Antenna Options
Various antennas, shown in Figures 3 and 4, are available from ADC for use with the DRU.
All antennas include a 6 foot (1.8 m) long 50-ohm coaxial cable (equipped with SMA male
connector) for connection to the DRU. The DRU is equipped with an SMA female connector
for connecting the antenna cable.
Note: To comply with Maximum Permissible Exposure (MPE) requirements, antennas must
be installed to provide at least 20 centimeters (8 inches) of separation from all persons per
FCC 47 CFR Part 2.1091.

1.3 AC/DC Power Converter
The DRU may be powered locally by the AC/DC converter, shown in Figure 6, which is available
as an accessory item. The converter is a UL Listed stand alone Limited Power Supply (LPS) unit
with a rated output of 48 Vdc at 1.2 A. The converter is equipped with a 6-foot (1.8 m) DC power
cable which is terminated with an RJ-45 male connector. The converter is powered by 120–240 Vac
(50–60 Hz) power which is supplied though a standard three-conductor AC power cord. The 120
Vac power cord is 6 feet (1.8 m) long and is provided with the converter.
