ADCP-75-112 • Issue 2A • June 2001 INTRODUCTION This publication provides instructions for installing the Digivance Indoor Coverage Solution (ICS) Digital Remote Unit (DRU). A more complete description of the DRU along with the operating and maintenance procedures is provided in the Digivance ICS Installation and Operation Manual (ADCP-75-110). The DRU is installed in conjunction with the Digital Host Unit (DHU) and the Digital Expansion Unit (DEU).
ADCP-75-112 • Issue 2A • June 2001 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.
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.
ADCP-75-112 • Issue 2A • June 2001 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.

AC/DC Power Converter 2 INSTALLATION PROCEDURE This section provides the installation procedures for the DRU, the antennas, and the AC/DC power converter (if used). Installation of the DRU may proceed separately from the installation of the DHU and the DEU. When the installation of the DRU is completed, refer to the Digivance ICS Installation and Operation Manual (ADCP-75-110) for the system turn-up and test procedures. 2.
ADCP-75-112 • Issue 2A • June 2001 2.2 Unpacking and Inspection This subsection provides instructions for opening the shipping boxes, verifying that all parts have been received, and verifying that no shipping damage has occurred. Use the following procedure to unpack and inspect the DRU: 1. Open the shipping carton and carefully unpack the DRU from the protective packing material. 2. Check the DRU for broken or missing parts.
ADCP-75-112 • Issue 2A • June 2001 2.4 DRU Mounting Procedure The DRU may be mounted on any flat vertical or horizontal surface. A slot is provided in each of the four mounting feet for inserting a fastener. The fasteners must be provided by the installer. Use the following procedure to mount the DRU: Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically-powered equipment.
