ID-O-Matic III
19
Connections
I/O connections to your equipment are made via a 12-position screw clamp type terminal block.
Pins 1 and 12 are marked on the board; pin 1 is toward the center of the board and pin 12 is
closest to the edge. Connections are as follows:
Pin Function
1
GROUND
2
POWER INPUT (6 to 20 V)
3
PTT OUT (keys the transmitter in FM repeater applications)
4
CW OUT (on/off keyed Morse code output, NOT audio)
5
BEACON INDICATOR output (active when beacon is being transmitted)
6
RESET - ground to reset the ID-O-Matic III
7
COR Input
8
Receiver audio input
9
ID INDICATOR (active when Morse ID is being transmitted)
10
ALT MSG input – selects the alternate CW ID message
11
Audio Out – Morse ID And tone output
12
GROUND
LED Indications
The LED is controlled by the ID-O-Matic firmware, and can be in one of four states:
OFF – This is usually an indication that there is no power supplied to the board.
SOLID GREEN – The ID-O-Matic is idle.
FLASHING GREEN – COR has been sensed, and a timing cycle is in progress.
FLASHING AMBER – PTT is active, and a timing cycle is in progress.
FLASHING RED – COR time-out has been reached; repeater function is disabled.
SOLID RED – An ID message is being transmitted, OR the terminal is in the setup menu.
These states are valid for firmware version 1.03 or newer. Earlier firmware versions do not have
the flashing red or amber indications.
Non-Repeater Use
It’s possible (and quite common) to use your ID-O-Matic III to provide automatic Morse or
voice ID for your HF, VHF or UHF transmitter or transceiver. Given the hundreds of different
HF, VHF and UHF rigs out there, I cannot provide specific instructions for them. In general,
though, it's a pretty simple proposition. For use with a voice rig (SSB, AM or FM) the ID-O-
Matic’s PTT output can key the transmitter while the audio output provides the Morse ID. There
is also a CW keying output for use with beacons or for CW operation.
