Section 1.0 Description
1.1 Introduction
This manual contains information on the UT12-000 Universal Tone Encoder\Decoder. Information in this
section consists of equipment, features and specifications.
UT12-000 Universal Encoder\Decoder
1.2 Purpose of Equipment
The UT12 is capable of encoding and decoding 5-tone CCIR tone sequences and encoding DTMF tones. It is
compatible with the AEM Tac/Com control head will provide broader and easier control over tones.
1.3 Features
System configuration data (such as identity codes) is programmed by use of front panel switches or by
connecting the UT12 to an IBM-compatible PC through the serial data port.
Front panel pushbutton controls are provided to allow the operator to perform the basic functions of
entering, sorting, recalling and transmitting tone sequences, as well as allowing the entry of configuration
data.
The UT12 is capable of alerting the user to various system conditions through either an externally
generated tone or by injecting a tone directly into the headphone audio line.
The UT12 may also be used as a data entry pad for the Tac/Com control head, allowing quick selection of
channels and entry of frequency data.
Based on the configuration data, control head settings, and tone inputs, the UT12 is capable of turning on
and off headphone audio from the transceiver to the head phone/audio controller.
The UT12 will operate on both the LA-M/Health Network (LAM) and Air Force Network (AFN). Operation
on each of the networks will be similar, with the exception of some differing 5-tone CCIR sequences. If
the transmit frequency falls between 147 MHz and 154 MHz the UT12 will operate on the AFN Network,
otherwise it will operate on the LAM Network.

Section 3.0 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the UT12-000
Universal Tone Encoder/Decoder.
3.2 General
The UT12 is capable of encoding and decoding 5-tone CCIR tone sequences and encoding DTMF tones.
It is compatible with the NAT Tac/Com system, and when used in conjunction with a TH-series Tac/Com
control head and NTX series transceiver it provides broader and easier control over radio communication.
3.3 Controls and Indicators
3.3.1 MON (Monitor) Switch:
The monitor switch is a two position locking toggle switch that can select between OFF and ON.
When in the Monitor OFF position, transceiver audio from the current channel (or home channel when
scanning) is only heard if the correct tone ID sequence is decoded.
When in Monitor ON position, transceiver audio from the current channel (or home channel when
scanning) is always heard.
The following functions are unaffected by the position of the MON Switch:
Transceiver audio is always heard from the priority scan channels, guard receive channels, and list scan
channels with correct tone sequences; Transceiver audio from list scan channels that do not have correct
tone ID sequence is not heard.
