1.1 Introduction

The T803 is an AC tone remote with alarm monitoring, voting tone generation and sim-

ple highsite control and is designed to fit into a Tait T800 Series II rack frame. It inter-

faces either a 2-wire or 4-wire line circuit to any standard T800 Series II receiver/

transmitter/exciter/power amplifier combination. It plugs into a backplane PCB

(which may be purchased separately or as part of a T800 Series II rack frame) which

eliminates wiring between the T803 and T800 Series II radios. The T803 is configured

using Tait PGM800Win programming software (V3.0 and later) which runs on a PC.

The T803 AC tone remote function enables a user to:

• remotely key a T800 Series II transmitter/exciter;

• defeat a receiver's CTCSS mute (to monitor a channel);

• change their set channel (up to 128 channels);

• change between base station and repeater modes (repeater knockdown);

• cancel alarms;

• turn repeater site equipment on or off (highsite control);

• loop back line audio (4-wire line interface only).

This is achieved using three industry-standard tone signalling plans for ease of integra-

tion into existing control systems and choice of vendor for office/control room equip-

ment. These plans are:

• EIA tone remote using a single function tone. In this system, when the control

room user presses the transmit key, the line control equipment sends a 120mS

burst of high level guard tone (HLGT - usually 2175Hz at +10dBM to line).

This is followed by a single 40mS function tone at 0dBm to line. This function

tone can change channel (1850Hz or 1950Hz) or monitor the radio channel

(defeat receiver CTCSS - 2050Hz). Other tones (1050Hz to 1750Hz in 100Hz

steps) can be used for various functions. Following these initial tone bursts, a

low level guard tone (LLGT - usually 2175Hz at -20dBm) is sent to line and

speech is gated onto line (at approx. 0dBm peak level). This continues until the

user releases the transmit key, whereupon speech is removed from the line and

LLGT tone ceases.

• EIA enhanced tone remote using two function tones. In this variant of the

above system two function tones are sent one after the other in the period

between HLGT and LLGT. The tone set is also expanded (650Hz to 2050Hz in

100Hz steps) to give 225 possible combinations which can be allocated to vari-

ous actions. Often the duration of both HLGT and function tones can be var-

ied.

• Simple Tx keying using LLGT. This is used where complex functionality is not

required. One application is to key a link transmitter where HLGT, the func-

tion tones and speech + LLGT are transparently carried to an end base station.

Note in this application the notch filters (which ordinarily remove the key tone

from the audio path) must be turned off using PGM800Win so that the keying

signal is propagated to the end transmitter.

The T803 can also generate voting tones where a 4-wire line interface is used. Voting

systems are used where several base station receivers are tuned to the same radio chan-

nel and located at different sites, sending audio back to a central control where the best

quality audio must be selected or "voted upon". Tone-on-idle or sliding voting tones

can be generated to interface a T800 Series II rack frame to a wide variety of industry

standard radio voting systems. In tone-on-idle applications, a tone (normally the same

frequency as LLGT) is transmitted to line when the T800 Series II receiver is muted.

When the tone disappears, control room equipment can perform signal-to-noise meas-

urements on incoming audio lines and select the best for feeding to the control room

user. In sliding voting tone systems a tone is transmitted to line whose frequency is pro-

portional to the T800 Series II receiver's RSSI. Control room equipment determines

which receiver has the highest RSSI and thus selects which line carries the highest qual-

ity incoming audio.

The T803 monitors three T800 Series II rack alarms (transmitter/PA forward & reverse

power and low battery/power supply), one line alarm (line fail indication) and four

external closure alarms. If alarms are triggered, the T803 will generate tone sequences

to alert system users of a problem.

The T803 has a width of 60mm and occupies a single space in a Tait rack frame, which

has the ability to accommodate up to seven standard modules.

2.1 Introduction

Figure 2.1 High Level Block Diagram

The T803 is connected to a leased line from control room equipment by means of an

RJ45 connector. 600R transformers are used to couple the audio into and out of the

T803. On the secondary of these line matching transformers are analogue transmission

switches which configure the line interface as either 2-wire or 4-wire compatible. Audio

from line is passed through an automatic level control (ALC) circuit before entering a

CODEC where it is digitised. The ALC ensures a good signal-to-noise ratio and effec-

tive radio channel utilisation for a wide range of line input levels. Audio to line is out-

put from the same line CODEC.

The line CODEC is connected to a digital signal processor (DSP) which is also connected

to a similar radio CODEC (the CTCSS CODEC is not used in this application). The

radio CODEC receives audio from the T800 Series II receiver and sends audio to the

T800 Series II transmitter/exciter to which it is connected via the special backplane PCB.

Receiver audio is low frequency filtered to extend the radio CODEC’s effective fre-

quency range.

The DSP processes the digitised audio streams from the CODECs in accord with instruc-

tions sent to it by the T803's microcontroller. The DSP can:

• detect HLGT, LLGT and function tones coming from line, notch filter line in

and receiver audio (used to eliminate LLGT from line out and transmitter

audio);

3.2.1 Torx Recess Head Screws

Torx recess head screws are becoming the standard screw head type in all T800 Series II

equipment, with Pozidriv and Philips recess head screws being used in fewer applica-

tions.

The Torx recess head has the advantage of improved screwdriver tip location, reducing

the chances of screw head damage caused by the driver tip rotating within the recess. In

addition, using a ball-tip Torx screwdriver allows you to drive a Torx head screw with

the driver on a slight angle, which can be useful in situations where access is restricted.

It is important that you use the correct Torx screwdriver tip:

M3 screws - T10

M4 screws - T20.

Figure 3.2 below shows a typical Torx recess head screw (actual hardware may differ

slightly from this illustration due to variations in manufacturing techniques).

3.2.2 Pozidriv & Philips Recess Head Screws

Pozidriv and Philips recess head screws will continue to be used in T800 Series II equip-

ment in a few special applications. It is important that you use the correct type and size

screwdriver for each screw type to avoid damaging the screw head.

It is particularly important that you do not use Philips screwdrivers on Pozidriv screw

heads as the tapered driving flutes of the Philips screwdriver do not engage correctly

with the parallel-sided slots in the Pozidriv screw head. This can result in considerable

damage to the screw head if the screwdriver tip turns inside the recess.

Note:

If you find you need excessive downwards pressure to keep the screwdriver

tip in the Pozidriv screw head, you are probably using the wrong type and/

or size screwdriver.

Figure 3.3 below shows the main differences between typical Pozidriv and Philips screw

heads and screwdriver tips (actual hardware may differ slightly from these illustrations

due to variations in manufacturing techniques).

3.3 Component Replacement

3.3.1 Leaded Components

Whenever you are doing any work on the PCB that involves removing or fitting compo-

nents, you must take care not to damage the copper tracks. The two satisfactory meth-

ods of removing components from plated-through hole (PTH) PCBs are detailed below.

Note:

The first method requires the use of a desoldering station, e.g. Philips SBC

314 or Pace MBT-100E.

3.3.1.1 Desoldering Iron Method

Place the tip over the lead and, as the solder starts to melt, move the tip in a circu-

lar motion.

Start the suction and continue the movement until 3 or 4 circles have been com-

pleted.

Remove the tip while continuing suction to ensure that all solder is removed from

the joint, then stop the suction.

Before pulling the lead out, ensure it is not stuck to the plating.

If the lead is still not free, resolder the joint and try again.

Note:

The desoldering iron does not usually have enough heat to desolder leads

from the ground plane. Additional heat may be applied by holding a sol-

dering iron on the tip of the desoldering iron (this may require some addi-

tional help).

3.3.1.2 Component Cutting Method

Cut the leads on the component side of the PCB.

Heat the solder joint sufficiently to allow easy removal of the lead by drawing it

out from the component side: do not use undue force.

Fill the hole with solder and then clear with solderwick.

If you are not using a prewired T800-27-000X rack frame, you will have to install a

T800-53-0000 3-bin tone remote backplane PCB into the left side (looking from the

front) of a T800 Series II rack frame.

If you are using a transmitter and need to use power alarms, connect LINK1 &

LINK2 on the backplane PCB.

Note:

For correct power alarm operation these links should be correctly set at

power-up.

Connect pins 1 and 2 of LINK5.

Remove any coaxial relay/duplexer from the T800 modules’ RF path and connect

the modules directly to an RF test set. Ensure that the transmitter/PA RF output

is sufficiently attenuated to prevent damage to the test set (refer to Figure 4.2).

Run up the receiver and transmitter/exciter/PA as instructed in the appropriate

T800 Series II service manual.

Install the T803, receiver and transmitter/exciter/PA in the rack frame as shown

in Figure 4.2.

Note 1:

A T800-03-0000 auxiliary D-range is required where remote channel change

or CTCSS defeat (for monitoring) is required.

Note 2:

A T1500-52-0000 should be fitted if a transmitter is being used and power

alarms are required.

4.2 Testing

Put the T803 into test mode by pressing the "Monitor On/Off" and "Mode Toggle"

buttons on the front panel simultaneously and holding them pressed for three sec-

onds.

Check that the T803 keys on the associated transmitter/exciter and encodes a

1kHz test tone to the transmitter/exciter for one minute. The test tone can be

heard on the built-in speaker and appears on the line out pair at -10dBm (2-wire)

or -14dBm (4-wire).

Adjust the "Line Sensitivity" control on the front panel of the transmitter/exciter

to give a reading on the RF test set of 60% system modulation, making allowances

for any CTCSS tone deviation.

Press the "Monitor On/Off" and "Mode Toggle" buttons on the T803 front panel

simultaneously to cancel test mode.

Use the RF test set to unmute the receiver.

Press the "Mode Toggle" switch on the T803 to put the unit into talk through

mode.

Modulate the RF carrier with a 1kHz tone at 60% system modulation, adding

CTCSS tone if necessary. Ensure that CTCSS tone is removed from the receiver’s

audio output by selecting the correct links inside the receiver.

Check that the transmitter/exciter is keyed on.

Adjust the "Line Level" control on the receiver front panel to produce 60% system

deviation at the transmitter/exciter RF output as measured on the test set.

The line levels are now automatically set to comply with ETSI TBR15 (2-wire line) and

TBR17 (4-wire line) specifications.

4.3 Fault Finding

1. Connect the T803 to its companion dispatch terminal via the leased line. Check

that speech sent from the terminal can be heard on the T803 speaker. One possible

cause of incorrect operation is that the line connections have become transposed

in the wiring network or that the dispatch terminal uses different Go/Return pairs

(also the speaker could be muted).

2. Use the console to key on the transmitter. If the transmitter does not key on, check

that the dispatch terminal and T803 have been compatibly programmed, i.e:

• check 2-wire/4-wire;

• check the keytone frequency;

• check if function tones are used;

• check high level guard tone and function tone periods (if used) are the same.

Finally check that the dispatch terminal is sending appropriate signal levels and

that tone durations are correct (which are often variable), and that the line is not

causing unacceptable attenuation or distortion.

3. If the dispatch terminal can key the transmitter but not change channel, repeater/

base station mode, auxiliary outputs, Rx defeat or cancel alarms, carry out the

checks in Step 1 above, but pay particular attention to the function tone program-

ming.

4. If the dispatch terminal can key the transmitter except when speech is present,

talkoff is occurring due to the keytone being 27dB lower than peak speech. Adjust

the relative levels inside the dispatch terminal (keytone should be 20dB lower

than peak speech).

5.1 Introduction

PCB Identification

All PCBs are identified by a unique 10 digit “internal part number” (IPN), e.g. 220-12345-00, which

is screen printed onto the PCB (usually on the top side), as shown in the example below:

The last 2 digits of this number define the issue status, which starts at 00 and increments through 01,

02, 03, etc. as the PCB is updated. Some issue PCBs never reach full production status and are there-

fore not included in this manual. A letter following the 10 digit IPN has no relevance in identifying

the PCB for service purposes.

Note:

It is important that you identify which issue PCB you are working on so that you can

refer to the appropriate set of PCB information.

Parts Lists

The 10 digit numbers (000-00000-00) in this Parts List are “internal part numbers” (IPNs). We can

process your spare parts orders more efficiently and accurately if you quote the IPN and provide a

brief description of the part.

The components listed in this parts list are divided into two main types: those with a circuit refer-

ence (e.g. C2, D1, R121, etc.) and those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within

each group. Each component entry comprises three or four columns, as shown below:

The mechanical and miscellaneous section lists the variant and common parts in IPN order.

Parts List Amendments

At the front of the parts list is the Parts List Amendments box (an example of which is shown

below). This box contains a list of component changes which took place after the parts list and dia-

grams in this section were compiled. These changes (e.g. value changes, added/deleted compo-

nents, etc.) are listed by circuit reference in alphanumeric order and supersede the information

given in the parts list or diagrams. Components without circuit references are listed in IPN order.

The number in brackets at the end of each entry refers to the Tait internal Change Order document.

Grid Reference Index

This section contains a component grid reference index to help you find components and labelled

pads on the PCB layouts and circuit diagrams. This index lists the components and pads in alpha-

numeric order, along with the appropriate alphanumeric grid references, as shown below:

Using CAD Circuit Diagrams

Reading a CAD circuit diagram is similar to reading a road map, in that both have an alphanumeric

border. The circuit diagrams in this manual use letters to represent the horizontal axis, and num-

bers for the vertical axis. These circuit diagram “grid references” are useful in following a circuit

that is spread over two or more sheets.

When a line representing part of the circuitry is discontinued, a reference will be given at the end of

the line to indicate where the rest of the circuitry is located, as shown below. The first digit refers to

the sheet number and the last two characters refer to the location on that sheet of the continuation of

the circuit (e.g. 1R3).

T800-53-0000 Parts List (IPN 220-01449-02)

How To Use This Parts List

The components listed in this parts list are divided into two main types: those with a circuit reference (e.g. C2, D1, R121, etc.) and

those without (miscellaneous and mechanical).

Those with a circuit reference are grouped in alphabetical order and then in numerical order within each group. Each component

entry comprises three or four columns: the circuit reference, variant (if applicable), IPN and description. A number in the variant col-

umn indicates that this is a variant component which is fitted only to the product type listed. Static sensitive devices are indicated by

an (S) at the start of the description column.

The miscellaneous and mechanical section lists the variant and common parts in IPN order. Where possible, a number in the legend

column indicates their position in the mechanical assembly drawing.

The Parts List Amendments box below lists component changes that took place after the parts list and diagrams in this section were

compiled. These changes (e.g. value changes, added/deleted components, etc.) are listed by circuit reference in alphanumeric order

and supersede the information given in the parts list or diagrams. Components without circuit references are listed in IPN order.

Parts List Amendments

There were no amendments to the parts list at the time of publication.
