Instruction Manual 4 Introduction This manual covers the Odyssey 2000 8RPT Repeater Radio for Digital Channel/Multicarrier Architecture, DCMA, with LTR trunking. This unit is a full duplex radio transceiver featuring digital technology developed by ComSpace Corporation, that greatly increases the traffic carrying capabilities of the radio network while at the same time improving the quality of communications. The principal features are: 1. 2. 3. Digital Modulation with DC/MA technology.
Instruction Manual 5 Warning One or more of the following statements may be applicable. FCC Warning This equipment generates or uses radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the Operator’s Manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made.
Instruction Manual 6 Safety: It is important that the operator is aware of, and understands, hazards common to the operation of any transceiver. WARNING: • FCC RF Exposure Compliance: FCC RF exposure compliance must be addressed at the time of licensing, as required by the responsible FCC Bureau(s), including antenna co-location requirements of §1.1307(b)(3). The applicable exposure limits, to demonstrate compliance, are specified in FCC Part 1.1310.
Instruction Manual 7 Precautions Please observe the following precautions to prevent fire, personal injury, and transceiver damage. • • • • Do not modify the transceiver for any reason. Do not expose the transceiver to long periods of direct sunlight, nor place it near heating appliances. Do not place the transceiver in excessively dusty, humid or wet areas, or on unstable surfaces. If an abnormal odor or smoke is detected coming from the transceiver, turn OFF the power immediately.

Instruction Manual 10 Repeater Controller Command Set Communication with the repeater controller is accessible through the RS232 port located on the front panel of this board. This connection requires a pin to pin compatible RS232 cable. A HyperTerminal must be started to communicate with the repeater controller. With a WINDOWS® operating system, the HyperTerminal can be found at: Start/Programs/Accessories/ HyperTerminal/HyperTerminal The HyperTerminal should be set up as follows.

Instruction Manual 12 Unpacking and Checking Equipment Note: The following unpacking instructions are for use by your ComSpace dealer, an authorized ComSpace service facility, or the factory. Carefully unpack the transceiver. ComSpace recommends that the items listed in the following table be identified prior to discarding the packing material. If any items are missing or have been damaged during shipment, file a claim with the carrier immediately.

The installations for the LAN Interface and MODEM are described in the Repeater Data Communications Instruction Manual.
Instruction Manual 14 Assembly The repeater should be assembled as indicated in the following diagram. The repeater, excluding elements like trunk controllers, LAN interface, and modem that are not shown in the diagram, consists of: 1) 2) 3) 4) 5) AC Power Distribution (not shown – mounted in rear of rack-based system), Power Supply Subsystem, Power Amplifier Subsystem, Low-Level RF Subsystem, and Digital Subsystem.
Instruction Manual 15
Instruction Manual 16 The assembly steps are as follows: 1) The two AC Power Distribution units (Tripp-Lite, IBAR 12/20 Ultra) should be mounted first. In a rack-based system, they will be mounted in the rear of the rack and in relay rack-based system, they will be mounted at the top of the front of the rack. In either case, they must be mounted in close proximity to the Power Supply Subsystem as the interconnect cabling between the units is on the order of one foot.
Instruction Manual i) 17 LAN Adapter Cable (060-00054-0001) 13) The rack should be grounded to a properly installed building ground. 14) Two AC lines of a minimum 20Amp service at 115V must be available for the repeater. These lines should be connected to the AC Power Distribution units. 15) Connect the Rx and Tx connection from the repeater to a duplexer or multicoupler/splitter system.
Instruction Manual 18 Basic Operation After all the cables have been properly connected, the repeater is ready for service. The transceiver frequency has already been pre-programmed at the factory and is confirmed on the shipping papers. To begin basic operation, simply follow these steps. 1) Turn on the power switches for the two AC Power Distribution units (Tripp-Lite, IBAR 12/20 Ultra) 2) Turn on the power breakers on the four RF power amplifiers (MAF860-25S).
Instruction Manual 19 Setting the Receiver Noise Floor Based on the ambient noise level at the repeater site, it is desirable to determine the noise floor of the site and to set the receiver appropriately. Setting the noise floor allows for the maximum dynamic range of the receiver to be used in decoding the radio signals.
