TB8100 Installation and Operation Manual Connection 55

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.

6.2 Power Supply Connections AC 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.
PAGE 5
Reciter 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.

.3 RF Connections The 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.

The standard system interface PCB is fitted to reciters bearing the product code TBA4xxx-0A0x or TBA5xxx-0A0x. If purchased separately, it has the product code TBA10A0. It provides: Standard ■ non-isolated 600Ω balanced audio I/O ■ high impedance unbalanced audio I/O ■ Tx key ■ Rx gate ■ RSSI ■ Tx relay ■ digital I/O. It is fitted with a 25-way female D-range connector and an auxiliary DC input connector. The pin allocations are listed in the table below.

Isolated This system interface PCB is fitted to reciters bearing the product code TBA4xxx-0B0x or TBA5xxx-0B0x. If purchased separately, it has the product code TBA10B0. It is the same as the standard model, except that the balanced audio interfaces are galvanically isolated. Isolated E&M This system interface PCB is fitted to reciters bearing the product code TBA4xxx-0C0x or TBA5xxx-0C0x. If purchased separately, it has the product code TBA10C0.

6.6 Microphone Connection You can connect a microphone to the TB8100 BSS via the standard RJ45 socket on the control panel. If a standard TB8100 microphone has not been supplied with your BSS, you should use an electret microphone. The pin allocations for the microphone socket are given in the following table.
