Only qualified personnel are allowed to change ACUs of an antenna. 2. RFS ACU devices are only compatible with RFS antennas. 3. The appearance of the ACU and the antenna depicted in the figures are only for reference and may differ from the actual ones. 1. SCOPE This document describes the operations to follow for:  Replacing on-site, an ACU device on an antenna, by a new one, or  Maintaining on-site, an ACU device that its firmware must be upgraded. This procedure is applicable for the RFS products that are listed herein after:  ACU-A20-S, ACU-A20-SR  ACU-I20-H12A, ACU-I20-H12B, ACU-I20-H12C  ACU-I20-B1, ACU-I20-B2, ACU-I20-B3, ACU-I20-B4, ACU-I20-B5, ACU-I20-B6, ACU-I20-B7, ACU-I20-B8  ACU-X20, ACU-X20H  ACU-X20-B5, ACU-X20-B6, ACU-X20-B7, ACU-X20-B8 2. REQUIREMENTS The required equipment for maintaining or configuring an ACU device on-site is given in Table 1. TABLE 1: EQUIPMENT LIST Item Equipment / Installation Tools 1 Case 1: Replacing a defective non-site-sharing ACU device A new ACU device, with its factory presets (i.e. default factory settings) Case 2: Upgrading the firmware of an ACU For an ACU-20 model, to plan:  1 device per band  1 AISG cable – ref. CA003-7 (Length is 30 cm) for daisy-chaining the ACU devices. It typically means:  2 ACU for a DualBand antenna + 1 AISG cable for chaining both the devices  3 ACU for a TriBand antenna + 2 AISG cables for chaining the devices  4 ACU for a QuadBand antenna + 3 AISG cables for chaining the devices For the other ACU families, there is no specific recommendation Case 3: Replacing a defective site-sharing ACU device A new ACU and CFG file of the antenna with the desired sharing mode Case 4: Changing the configuration of a static site-sharing ACU device A new STATIC configuration SHA file defined for the specific antenna model MAINTENANCE GUIDE www.rfsworld.com Antenna Control Unit Maintenance Guide 10000025991 | Revision 2 | November 2021 | © Radio Frequency Systems 2021 4 2 Antenna Line Configurator (PC /NEM /Adaptor) PC: Ensure that the USB drive and CP210X device drive are installed on the computer. The NEM-ALD -W application software is installed. 3 Adaptor: PA-USB/485-1 Used for COMPUTER USB port and ACU communication protocol adapter. 4 Full link: Use the USB port of the adapter to connect to the USB port of the computer. Use the AISG port of the adapter to connect to the AISG port of the ACU. Connect the power supply using the power cable port of the adapter. 5 AISG cable This is used for connecting the adaptor to the AISG port “IN A” (or “IN 1”) of an ACU device. NOTE: Never connect the AISG cable to the AISG port “IN B” (or “IN 2”) of an ACU device to maintain or to configure 6 Wrenches A pair of screws allows the ACU device to be fixed on the antenna. Two types of screws exist: it depends on the ACU type. Please, refer to the Table 2 for getting the screw type for the ACU to dismantle and to replace. NOTE: For the ACU-A20 family, a 5 mm Allen wrench is required in addition to the Cruciform/Torx wrenches Crucifor m head Torx T20 head TABLE 2: WRENCH TYPE PER ACU MODELS Family Overview of the Device ACU Model Wrench Type A20 ACU-A20-S ACU-A20-SR I20-H ACU-I20-H12A ACU-I20-H12B ACU-I20-H12C X20 and X20H ACU-X20 ACU-X20H I20-B ACU-I20-B1 ACU-I20-B2 up to ACU-I20-B8 X20-B ACU-X20-B5 up to ACU-X20-B8
