6 Connection Once the TB8100 BSS hardware is installed, you need to connect the individual modules to each other, and to any ancillary equipment required in your system. This chapter provides information on all the inputs and outputs available on the TB8100 BSS. 6.1 Overview of Inputs and Outputs This section identifies the main input and output connections for the TB8100 BSS. Figure 6.1 below identifies the connections at the front of a dual base station, and Figure 6.3 on page 57 identifies those at the rear. Figure 6.2 on page 56 identifies the connections at the front of a single 100W base station. Figure 6.4 on page 57 identifies the connections on the control panel. Refer to the following sections in this chapter for more details on these connections.

We recommend that a standard 3-wire grounded outlet is 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 a maximum of 600W. The requirements of two typical AC supplies are given in the following table. Nominal Supply Current Requirement Circuit Breaker/Fuse Rating 115VAC 230VAC 8A 4A Your TB8100 BSS should come supplied with a power supply cord to connect the male IEC connector on the PMU to the local AC supply. The pins of the IEC connector on the PMU are identified at right. 10A 6A rear view neutral ground phase DC Power The TB8100 PMU is designed to accept a DC input of 10.3 to 15.5VDC with negative or positive ground. There is a minimum DC start-up 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 a rating of 60A. The DC input leads should be of a suitable gauge to ensure less than 0.2V drop at maximum load over the required length of lead. Terminate and insulate the DC input leads so they are protected from accidentally shorting to the subrack if the PMU is removed before the leads are disconnected. Figure 6.5 Recommended DC Power Connection Circuit Breaker or Fuse PMU Battery 58 Connection TB8100 Installation and Operation Manual Tait Electronics Ltd June 2003 Reciter Auxiliary DC Input PMU Auxiliary DC Output The system interface PCB in the reciter has an auxiliary DC input connector. DC from the auxiliary DC output on the PMU (see PMU Auxiliary DC Output below) can be supplied to the +AUX_V pin on the system interface connector via this input. The pin allocations for the auxiliary DC input on the system interface PCB are given in the following table. Note that pins 1 & 3 and pins 2 & 4 on this connector are linked. Refer to System Connections on page 60 for the pin allocations for +AUX_V on each system interface PCB. Pin Description Links 3 4 1 2 rear view 1 2 3 4
+V input ground
+V input ground The DC output from the PMU is 12VDC. Although this power output is isolated, the negative side of the supply is grounded on the system interface PCB to give a +V output. The PMU can provide an auxiliary DC output when it is fitted with the optional 40W auxiliary power supply PCB. This power supply is current limited to 3A and is available on the auxiliary DC output connector on the rear panel. DC from this output can be supplied to the +AUX_V pin on the system interface connector on the reciter via the auxiliary DC input connector on the system interface PCB (see Reciter Auxiliary DC Input above). The pin allocations for the auxiliary DC output on the PMU are given in the following table. Note that pins 1 to 4 and pins 5 to 8 on this connector are linked.

The RF output is via the N-type connector on the rear panel of the PA (refer to Figure 6.3 on page 57). We recommend that you use dual-screened coaxial cable such as RG223 for the BNC connections, and RG214 for the N-type connections. 6.4 System Connections The reciter can be fitted with an optional system interface PCB which provides the links between the reciters internal circuitry and external equipment. This PCB is securely mounted to the reciters chassis and is connected to the control PCB with a flexible connector. The system interface PCB is fitted with industry-standard connectors and several standard types are available for different applications. The circuitry on the system interface PCB provides additional signal processing so that the outputs meet standard system requirements. It also enables the PCB to identify itself to the reciter control circuitry. The system interface PCB is removable, which makes it possible to change the application of a reciter by removing one type of PCB and fitting another. Only one system interface PCB can be fitted to a reciter at any one time. This section provides details on the system interface PCBs available at the time of publication. Other types may be developed for future applications. Figure 6.6 System Interface PCB system interface PCB*
