Blank Panels Power Amplifiers Channel Cards RX Slaves RX Master TX Master 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. 2) The Power Supply Subsystem (075-00028-0001) should be mounted in the rack next. Space should be left for later installation of a 1U blank panel (300-00056-0001) which is installed above the Power Supply Subsystem. As previously noted, the Power Supply Subsystem must be in close proximity to the AC Power Distribution units. 3) The interconnecting cables (060-00053-0001) between the AC Power Distribution and the Power Supply Subsystem enclosure should be installed next. 4) The Power Amplifier Subsystem enclosure (MR860-41S) should be mounted in the rack next. 5) With the Power Amplifier Subsystem enclosure in place, the four RF power amplifiers (MAF860-25S) should be inserted in the enclosure and retained in place with the captive hardware. 6) The Low-Level RF enclosure (075-00027-0001) should be installed next. 7) The Digital Enclosure with backplane (075-00026-0001) should be installed next. 8) The Fan Tray (Comair Rotron 31038) should be installed next. 9) The two 1U blank panels (300-00056-0001) should be installed at the top and bottom of the installed units. 10) With the subsystem enclosures in place, install the following cables:
a) PA Power Cable (060-00016-0001) b) LLRF Power Cable - +/- 15 VDC(060-00025-0001) c) Digital Power Cable (060-00024-0001) d) Digital Power Cable - +/- 12 VDC (060-00026-0001) e) Digital Power Sense Cable (060-00023-0001) f) Trunking Controller Power Cable (060-00032-0001) 11) With the Digital Enclosure installed, the digital cards must be inserted in the following order:
Note: Proper grounding practice should be followed while inserting all of the digital cards. a) The Repeater Controller (050-00003-0200) must be inserted into slot one. b) The Tx master (050-00004-0203) must be inserted into slot two. c) The Rx master (050-00004-0201) must be inserted into slot three. d) The two Rx Slaves (050-00004-0202) must be inserted into slots four and five. e) The four Channel Cards (050-00023-0200) must be inserted into slots eight through eleven. 12) Install the following interconnect cables:
a) Exciter Signal Cable (060-00040-0001) b) RF/Digital DB-25 Communications Cable (060-00051-0001) c) RF/Digital DB-9 Communications Cable to PA (060-00055-0001) d) RF/Digital DB-9 Communications Cable to LLRF (060-00042-0001) e) RF/Digital Coaxial 13MHz Reference Cable (060-00034-0001) f) Two Trunking Controller DB-15 cables (short length) (060-00049-0001) g) Three Trunking Controller DB-15 cables (medium length) (060-00049-0002) h) Three Trunking Controller DB-15 cables (long length) (060-00049-0003) Instruction Manual 17 i) 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). 3) Turn on the main power switch on the Power Supply Subsystem (075-00028-0001). After an approximately five minute timeout period, the 13MHz ovenized crystal oscillator will be sufficiently stabilized, and the repeater will begin modulating and transmitting a pseudo-random DC/MA signal. The frequency and other repeater parameters can be checked by connection a computer running a HyperTerminal and typing in the syspar command. 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. The steps for setting the receiver noise floor are:
1) Using the data logging capability of the repeater, establish the value for the noise floor based on the receive antenna configuration. Using the noise floor value and the table of noise floor values versus receive amplifier voltage settings, select the proper receive amplifier voltage setting and adjust the receiver amplifier voltage to the proper voltage value.
