4.6 Connecting Up the Base Station This section provides information relevant to the task of connecting up the various inputs and outputs of the base station. 4.6.1 Connection Overview The connections at the rear of a dual 50W base station are identified in Figure 4.9. External connections are all located at the rear of the subrack. Figure 4.
4.6.2 Connecting AC Power The PMU is designed to accept a mains input of 88 to 264VAC at 45 to 65Hz. A standard 3-wire grounded socket outlet must be used to supply the AC power. The socket outlet must be installed near the equipment and must be easily accessible. This outlet should be connected to an AC power supply capable of providing at least 600W. The requirements of two typical AC supplies are given in the following table.
4.6.3 Connecting DC Power The PMU is designed to accept a nominal 12VDC, 24VDC or 48VDC input (depending on the model) with negative or positive ground. There is a minimum DC startup threshold to prevent damaging a battery which has little capacity left. You must connect the DC supply from the battery to the PMU via a fuse or DC-rated circuit breaker with the appropriate rating, as shown in the table below.
.6.4 Connecting the Auxiliary DC Power Output The PMU can provide an auxiliary DC output from the auxiliary power supply board. This board is available with an output of 13.65VDC, 27.3VDC, or 54.6VDC (depending on the model), and is current limited to 3A, 1.5A or 750mA respectively. This power supply is permanently on as soon as the base station has finished powering up, and is available on the auxiliary output connector on the rear panel.
4.6.5 Connecting RF Notice Do not remove the load from the PA while it is transmitting as this may damage the PA output stage. Before disconnecting any RF cables, put the base station into Offline mode to prevent any transmissions. The RF input to the base station is via the marked BNC connector on the rear panel of the reciter. The RF output is via the N-type connector on the rear panel of the PA (refer to Figure 4.9 on page 70). Cables and antennas should be of high quality construction.
4.6.6 Connecting an External Frequency Reference An external reference frequency is not normally required for B band. However, an external reference can be used when you need to maximize the range of the base station. For K4 band, the internal frequency reference accuracy is inadequate, and an external reference must be used. The external reference frequency can be 10MHz or 12.8MHz, with an input level of 300mVpp to 5V pp. The stability of this reference should be better than 100 parts per billion.
4.6.7 Ethernet Connection The RJ-45 socket on the reciter’s rear panel provides the 1-BASE-T or 100BASE-T Ethernet connection to the other devices in the network. Use a Cat-5 cable to connect this socket to the Tait Network via a router or switch. The Web UI allows you to set the Ethernet port speed auto-negotiation to 10/100 Mbit/s or to negotiate a maximum 10 Mbit/s. Tait recommends that you keep the port speed at the factory default setting of 10 Mbit/s.
4.6.8 Connecting General Purpose Inputs and Outputs The base station has a number of general purpose inputs and outputs. These are connected via the 25-way D-range on the rear panel. The pin allocations for the D-range connector are given in the following table. Not all pins are used in this release of the base station.
5 Working with Base Stations from Your PC The normal web browser on your PC provides a window into the TB9300 base station. Use it to connect to the base station so that you can monitor, configure, diagnose, and calibrate it (if required). This section describes the following: ■ Connecting to the base station, including initially setting things up. ■ Working with base station web pages. ■ Carrying out basic tasks. This section provides an overview of some aspects of the web interface.
