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.

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.
Nominal Supply
Current Requirement
115VAC
8A
10A
230VAC
4A
6A
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.

Rating

phase
rear view
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.

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. Refer to “System Connections” on page 60 for the
pin allocations for +AUX_V on each system interface PCB.

Links
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.

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.
6.4
System Connections
The 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.

Service Kit Connections
The TB8100 service kit is connected to the BSS via the RS-232 serial port
on the control panel. This port is a 9-way female D-range connector. Use
a straight through cable, as supplied with the service kit, to connect your
programming computer to the BSS. The pin allocations for the serial port
are given in the following table. Note that pins 1, 4 & 6 and pins 7 & 8 are
linked. This port is also used for remote connection to the Service Kit or
Alarm Center software via a modem or radio modem.
