Page 9 Welcome to the TB8100 Service Kit User’s Manual. This manual provides you with information about the Tait TB8100 Service Kit in PDF format. You can view it online or print it if you want a paper copy. It describes how to use Version 1.00 of the Service Kit.
Page 10 Technical notes are published from time to time to describe applications for Tait products, to provide technical details not included in manuals, and to offer solutions for any problems that arise. Look for them on Tait’s technical support website. The following have been published or are in development: TN-742 Remotely Monitoring and Configuring the Tait TB8100.
Page 11: Introduction
Part A Introduction The Service Kit is a Windows-based software program that makes it easy to monitor and configure a Tait TB8100 base station. You can also use it to carry out diagnostic tests and update the base station’s firmware.
Page 13: From T800 To Tb8100
From T800 to TB8100 The TB8100 is a software-based radio. This means that its programming software has far more scope. For those who are familiar with the Tait PGM800Win programming software, here are some key differences. The Service Kit does more than configure channels. It can monitor operational details, receive alarms, log a user-defined set of parameters, and carry out diagnostic tests.
Page 14: Operation Modes
Operation Modes base station can operate in three different modes. Some functions are disabled until you shift the base station into the required mode. Run mode is used for normal operation. Standby mode is required if you want to program the base station or carry out diagnostic tests on it.
Page 15: Channels
Channels A TB8100 base station consists of the equipment needed to operate on just one channel. However, using the Service Kit you can program up to 255 channels into a single base station. This is confusing, until you realize that ‘channel’ has different meanings.
Page 16: Profiles
Profiles Profiles are groups of configuration settings. They simplify the task of configuring channels. The base station has a large number of configuration settings, but most of these will be the same for all channels. Instead of configuring all options many times over for each channel, you configure them once in a profile.
Page 17: Subaudible Signalling
Subaudible Signalling The TB8100 base station can transmit and receive using subaudible signalling. Both CTCSS tones and codes are supported. CTCSS attaches a subaudible tone to the carrier signal. DCS attaches a digital code. A receiver programmed with a particular tone or code will not unmute unless that tone or code is presented with the RF signal.
Page 18: Power Saving
Power Saving The TB8100 base station can save power by switching off parts of its circuitry. The standard base station has a limited ability to reduce the current that the base station uses, but the Power Saving Modes license lets you configure three different power saving modes.
Page 19: Task Manager
This customizes the way the base station operates without modifying its firmware. Task Manager can perform many functions that previously required expensive external equipment. TB8100 Service Kit User’s Manual Task Manager 9...
Page 20: Tasks And Comments
In a standard base station, Task Manager can process up to 40 tasks. In a base station with an Advanced Profiles and Task Manager license, Task Manager can process up to 200 tasks. Tasks and Comments Task Manager acts only on the basis of the tasks in its task list. A task is rather like computer code and takes the form: IF <...
Page 21: Custom Inputs And Actions
Similarly, a custom action can combine up to eight actions. When a task with a custom action is processed, all its constituent actions are carried out. You can also use counters, timers, and your own flags when defining tasks. TB8100 Service Kit User’s Manual Task Manager 11...
Page 22: Remote Connections
The remote link can consist of a telephone line with modems at each end, a pair of radio modems, or a pair of Tait radios that support the CCDI2 protocol. For each remotely linked base station, you need to create a ‘connection,’ which is a named configuration that tells the Service Kit how to communicate with the base station.
Page 23: Alarms
Alarm notification methods need to be set up and configured. Choose carefully which ones to implement, based on the available resources and your policy for remote monitoring. See TN-742, Remotely Monitoring and Configuring the Tait TB8100, for details. To set up an alarm notification method, you may need a physical link (for example, modems and a telephone line).
Page 24: System Interface
System Interface The base station reciter can be fitted with a system interface board. Several different boards make a variety of inputs and outputs available for different applications. Select Monitor > Module Details > Reciter to see which system interface is fitted.

Page 30: Monitoring Alarms
Monitoring Alarms When you are logged on to a base station, the Service Kit regularly polls the base station for alarms. If an alarm is detected, a flashing Alarms icon appears in the status bar. If the Alarms icon disappears, the Service Kit has detected that the alarm was cleared.

Page 34: Configuration Tutorial
Configuration Tutorial The following tutorial shows you how to make some basic changes to the standard configuration that turn the TB8100 into a basic repeater. You modify the signal path, change from carrier gating to noise gating, optionally configure subaudible signalling, and set the receive and transmit frequencies. The aim is to get you started and to introduce you to some of the many configuration settings that are covered in the online Help and the manual.

Page 52: Working With Base Station Configurations
Working With Base Station Configurations Base stations are programmed with many configuration settings. Using the Service Kit, you can view these settings, change them, and then program them into the base station. You can also create a new configuration from a template and save a configuration to a file.
Page 53: Creating A New Configuration
1. Select File > New. The Select Template File dialog box appears. 2. Select an appropriate template (*.t8t file) from the templates in the Template folder. This template will provide a set of default settings. Templates can be provided by Tait or created for your system or organization. 3. Click Open.
Page 54: Saving A Configuration
When you read a configuration and the base station Important: cannot detect its PA or PMU, it is unable to provide the configuration settings that are stored in the module. The Service Kit fills in the gaps by providing default settings. If this occurs, you might subsequently overwrite the module’s settings with defaults that are unsuitable for your system.

RF Configuration In the Add or Edit Channel Profile dialog, General tab, the RF configuration area lets you specify the nominal channel spacing for the receiver and the transmitter.
Page 107 When signal levels are high, however, the minimum sensitivity may be degraded. AGC is normally enabled, but Tait recommends disabling it when: The anticipated receive signal strength is < -107 dBm (1 microvolt) and strong interfering signals (> -30 dBm (7000 microvolts)) are anticipated at the receiver input.
Page 108 Receiver Gating In the Add or Edit Channel Profile dialog, General tab, the Receiver Gating area configures receiver gating (also known as receiver squelch). You can have gating based on RSSI or SINAD. If you select both options, gating is enabled once both values reach the required level. RSSI gating operates more quickly and is suitable for repeater links.
