TB8100 Service Kit User's Manual
A Tait TB8100 base station consists of the equipment necessary
to receive and transmit on one channel. Generally, this means a
reciter, a PA, and a PMU. Often abbreviated to TB8100 or base
station.
A TB8100 is a talk through repeater when its audio path is
configured to pass the audio it receives on to the transmitter.
Task Manager is a part of the TB8100 base station firmware that
carries out tasks in response to inputs. These tasks are formulated
using the Service Kit.
A template file contains configuration information that can be
used to create a new base station configuration. Template files
have the extension *.t8t.
The transmit lockout feature prevents the base station from
transmitting for a time once the transmit timer has expired. It is
designed to prevent users from monopolizing the base station.
An unbalanced line has one wire earthed. It is typically used for
short connections, for example, between a base station and a
repeater on the same site. The system interface identifies the
wires of unbalanced lines with Rx audio, Tx audio, and Audio
Ground. Audio Ground is common to line in and line out.
A valid signal is a signal that the receiver responds to by opening
the receiver gate. A signal is valid for example when it is stronger
than a minimum level and when it has the specified subtone.
Voltage Standing Wave Ratio (VSWR) is the ratio of the
maximum peak voltage anywhere on the line to the minimum
value anywhere on the line. A perfectly matched line has a
VSWR of 1:1. A high ratio indicates that the antenna subsystem
is poorly matched.
