Product Overview P RODUCT O VERVIEW InterReach Spectrum supports up to eight frequency bands in a single system. Each antenna location supports those bands in modular, group pairings. Each location includes a Main Remote Access Unit (MRAU), which can power up to three additional Secondary Remote Access Units (SRAUs). An MRAU supports two frequency bands, and each SRAU can support up to two frequency bands, for a total of up to eight frequency bands.
Product Overview Main Remote Access Units The Main Remote Access Unit (MRAU) receives FWD IF signals from an IF Expansion Unit (IFEU), which is part of the Spectrum Expansion Module Group, using 75 CATV cable. The MRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The MRAU also receives configuration information and power from and sends its status information to the IFEU. The MRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

Product Overview Secondary Remote Access Units A Secondary Remote Access Unit (SRAU) receives FWD IF signals from the MRAU, using 75 CATV cable. The SRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The SRAU, through the MRAU, also receives configuration information and power from and sends its status information to the IFEU. The SRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.
Product Overview SRAU LEDs SECONDARY SECONDARY REV Ref # LED 1 2 3 STATUS 1 2 3 LED Color Description • Green • SRAU receiving communications from the IFEU. • Red • SRAU has not received communications from the IFEU for more than 90 seconds. • Off • During initial power up, SRAU is powering up and waiting for IFEU communications. • Green • Unit has no alarms or a Minor alarm is active. • Blinking Green • Unit or band is set out-of-service. • Red • Major alarm detected.
Product Overview RAU N Connectors Each RAU also has one or two 50- N-type connectors that connect to a passive antenna. Table 3 lists the number of N-type connectors available on each RAU model. Table 3.
Install the RAUs and Antennas I NSTALL THE RAU S AND A NTENNAS Follow the steps in the order provided to install the RAUs and antennas. Mount the RAUs and Antennas General Safety Precautions CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm.
Install the RAUs and Antennas Do the following, in the order presented, to mount the RAUs and antennas: 1 Mount all MRAU and SRAUs in the locations marked on the floor plans. 2 Install the passive antennas according to the manufacturer’s installation instructions. NOTE: It is common practice to install passive antennas below the ceiling. If you install a passive antenna above the ceiling, when estimating the antenna coverage area, account for additional loss due to the ceiling material.
Install the RAUs and Antennas 6 Connect F connector CATV cables on the IFEU and MRAU, in the order given below. If the LEDs do not perform as described in this procedure, refer to “MRAU LEDs” on page 6. a Connect a CATV cable from one of the IFEU FWD Module IF OUT connectors (1 - 8) to the MRAU FWD IF IN connector. b Confirm that the MRAU FWD IF IN LED is yellow, which indicates a correct physical connection.
Install the RAUs and Antennas Connect the MRAU to SRAUs CAUTION! To prevent interference, do not install an 850/1900 MRAU antenna near an 800/900 SRAU. The 850 MHz band must be 20 feet away from the 800/1900 SRAU’s passive antenna. 7 Use one of the following 6’ and 20’ CATV RG6 jumpers, available for purchase from ADC, to connect an MRAU to SRAUs. ADC Part Number Description Note 300469-0 6’ RG-6 Cable; F Male to F Male CATV cable that connects the MRAU to SRAUs. Two cables required per SRAU.
Install the RAUs and Antennas 10 Repeat Step 9 to install up to two more SRAUs, as per system design.
