Installation and Operator Handbook 3 3.1 Installation Instructions INSTALLATION INSTRUCTIONS GENERAL This chapter provides a detailed description of the installation procedure for the DRB-25 Dual Channel Radio System and should be read before starting the installation. Use the Installation Instructions in conjunction with the configuration checklist for the specific system being installed. 3.

Installation and Operator Handbook 3.3 Installation Instructions SITE REQUIREMENTS Before installing the DRB-25 at the operating site, the following details regarding antenna installation and safe operating distances, desk or floor space, rack clearance and lightning protection should be considered. 3.3.1 Antenna Installation and Safe Operating Distances Use only manufacturer or dealer supplied antenna. Antenna Minimum Safe Distance: 70 cm, 50% Duty Cycle. Antenna Gain: zero dBd referenced to a dipole.
PAGE 4
Installation and Operator Handbook 3.3.3 Installation Instructions Lightning Protection To minimize damage to equipment, or injury to maintainers, a complete system of lightning protection and grounding connections should be installed. The following points should be considered: 3.4 • All down conductors, bonding interconnections, ground rings and radial tapes should be un-insulated solid copper tape at least 25 x 3 mm in cross section.
PAGE 5
Installation and Operator Handbook Installation Instructions Unpack the DRB-25 as follows: 3.5 • Carefully remove the DRB-25 cabinet from its packaging and relocate to a convenient level work surface. • Remove all protective wrapping and inspect the cabinet for signs of damage or loose parts. Notify the supplier or its agent immediately if any is noted. • Remove each of the modules in turn from their packages, unwrap and inspect as for the cabinet.

Installation and Operator Handbook Installation Instructions Figure 3-1 DRB-25 Rack Mounting Arrangement 3.5.3 Configuring DRB-25 Identity (Box ID) An 8-way DIP switch on the backplane adjacent to Transceiver 2 enables a Box ID to be set for each DRB-25. The switch is accessed from the front of the unit with the modules removed. A total of 256 identities are available. The Box ID is used by each Transceiver to determine its default settings on power-up.

Installation and Operator Handbook 3.5.4 Installation Instructions 2. Using a screwdriver or pen, set the eight sections of the DIP switch to the desired Box ID, according to and the intended DRB-25 Box numbering plan. 3. The Switch 1 (LSB) is the top switch; Switch 8 (MSB) is the lower switch. OFF is to the left, ON is to the right. Installing the Modules Refer to the following figures (Figure 3-2, Figure 3-3 and Figure 3-4) to identify the correct position for each module within the DRB-25 cabinet.
