The ID-O-Matic kit uses a microprocessor based, single chip ID timer/annunciator intended for Amateur
Radio and other applications. Several modes of operation make it suitable for use in the shack or as an
automatic Morse code ID for beacons, repeaters and "fox hunt" transmitters. The ID-O-Matic chip is a
compact, single 18-pin package ideal for standalone use or integration into transmitter or transceiver. These
instructions detail the assembly and use of the ID-O-Matic kit.

Summary of Contents for NOXAS ID-O-Matic
- Page 1 Radio and other applications. Several modes of operation make it suitable for use in the shack or as an automatic Morse code ID for beacons, repeaters and “fox hunt” transmitters. The ID-O-Matic chip is a compact, single 18-pin package ideal for standalone use or integration into transmitter or transceiver. These instructions detail the assembly and use of the ID-O-Matic kit.
- Page 2 VR1, any smooth, regulated DC voltage from 3 to 5.25 V should work fine. Three AA alkaline cells should last quite a while for shack use as a simple ID reminder. If you plan to build your ID-O-Matic into a rig or a repeater controller,...
- Page 3 At nine minutes thirty seconds, the LED will begin to blink yellow and red. After ten minutes the LED will turn solid red and the ID-O-Matic will start to beep at you to remind you to ID. The open-drain PTT output can be used to drive an external indicator such as a lamp or LED.
- Page 4 For beacon, foxhunt or repeater use, connect your ID-O-Matic to a PC or other serial terminal device using a straight-through 9 pin serial cable. If you have built your own custom device using the ID-O-Matic chip, you can use the kit schematic as a guide to build your own interface level converter.
- Page 5 The PTT and CW outputs are open-drain MOSFET outputs, and can be directly connected to inputs that do not exceed 60V or 20 mA at any time. They can be used to drive low current relays if needed. If you intend to use the ID-O-Matic with equipment requiring grid-block or cathode keying or any other application that will exceed 60 Volts or 200 mA, you will need to add a grid-block keying adapter such as the Universal Keying Adapter 2 or some other suitable output arrangement.
- Page 6 A kit is available to make connecting your ID-O-Matic to other equipment much easier. The Connection Kit provides inverting and non-inverting inputs, voltage limiting, an audio amp/mixer/filter, and optional PTT for many handheld transceivers. It is designed to plug directly onto the ID-O-Matic board “piggy-back” style. You can check out the Connection Kit at www.HamGadgets.com.
