TB8100 Installation and Operation Manual Connection 55© Tait Electronics Ltd June 20036 ConnectionOnce 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 OutputsThis 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.Figure 6.1 Dual 5 or 50W Base Station Inputs and Outputs - Front Viewb28VDC high current output for PA f28VDC high current input cable from PMUc28VDC low current output for reciter gRF output to PAdsystem control bus h28VDC low current input from PMUeRF input from reciter iDC output (for optional reciter fan only)bcd e ghfghddidiefdPA 1 PA 2 reciter 2PMU reciter 1

58 Connection TB8100 Installation and Operation Manual© Tait Electronics Ltd June 20036.2 Power Supply ConnectionsAC Power The TB8100 PMU is designed to accept a mains input of 88 to 264VAC at 45 to 65Hz. 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.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.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.Nominal Supply Current Requirement Circuit Breaker/Fuse Rating115VAC 8A 10A230VAC 4A 6Aphaseneutralgroundrear viewFigure 6.5 Recommended DC Power ConnectionBatteryPMUCircuit Breakeror Fuse
TB8100 Installation and Operation Manual Connection 59© Tait Electronics Ltd June 2003Reciter Auxiliary DC Input 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. 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.PMU Auxiliary DC 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.Pin Description Links1+V input2 ground3+V input4 ground1234rear viewPin Description Links1 +V output2 +V output3 +V output4 +V output5 ground6 ground7 ground8 ground15263748rear view
60 Connection TB8100 Installation and Operation Manual© Tait Electronics Ltd June 20036.3 RF ConnectionsThe RF input to the TB8100 BSS is via the lower 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 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 ConnectionsThe reciter can be fitted with an optional system interface PCB which provides the links between the reciter’s internal circuitry and external equipment. This PCB is securely mounted to the reciter’s 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 PCBsystem interface PCB*control PCB*standard system interface PCB shown
