The ID-O-Matic II 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 II includes
audio mixing, de-emphasis and amplification as well as input signal conditioning and output drivers.

- Page 3 Kit Construction: Keep all semiconductor parts in the anti-static packaging until you are ready to use them. Always use good static prevention practices when working with static sensitive parts. This means you should wear a grounding strap when possible, or work on a static-dissipative work surface. Use a grounded tip soldering iron.
- Page 4 Install a 100K Ohm resistor in location R8. Install the 470 Ohm resistor (yellow-violet-brown) at R2. Install the 1K Ohm (brown-black-red) resistor in location R3. Install a 1K Ohm resistor in location R12. Install a 1K Ohm resistor in location R13. Install a 2.2K Ohm (red-red-red) resistor in location R4.
- Page 5 Carefully install the small 20 MHz cylindrical crystal in location X1. NOTE: This part is easy to damage with excess heat while soldering. Be extra careful! Install the DB-9 connector in location J1. If you purchased the terminal block, install it at J1 now. Make sure the “open” side where there are openings for wires faces the outside edge of the board.
- Page 6 J1-7 COR input. Normally used for a COR or squelch signal from the receiver. This signal was known as START on the original ID-O- Matic. J1-8 Receiver audio input. J1-9 INHIBIT input. Can be used to hold off ID if needed. J1-10 Audio output.
- Page 7 and no (unused) INHIBIT. The COR jumper is connecting the center and L pins, and the INH jumper is left open. Additional Solder Pads: You will note there are three additional solder pads to the right of the PIC processor, marked A3, A4 and B0.

Page 8: Operation
Operation Simple timer mode: For shack use as a simple ID reminder, simply turn the ID-O-Matic II on. The LED should show green for nine minutes, then turn yellow. At nine minutes thirty seconds, the LED will begin to blink yellow and red. - Page 9 Three separate messages can be entered at setup time. They are used as follows: • ID Message: This is the “normal” ID message, sent when the timer expires. • Beacon message: This message is optional. If you wish to have your repeater or link transmit a different ID message after a period of inactivity, you can use this message.
- Page 10 Setting Up the ID-O-Matic II For beacon, foxhunt or repeater use, connect your ID-O-Matic II to a PC or other serial terminal device using a straight-through 9 pin serial cable. If using a PC you can use the HyperTerminal program provided with some versions of Windows, or just about any other serial communications program such as PuTTY or Minicom.
- Page 11 • Courtesy beep tone: This prompt will only appear if you answered “Y” to Repeater mode. With the courtesy beep tone set to an audio frequency (in Hz) between 250 and 2500, the ID-O-Matic II will send a short beep about 500 milliseconds after the COR input goes inactive. •...

I will make every effort to respond as quickly as possible. Documentation and troubleshooting information can be found at http://www.HamGadgets.com. - Page 13 Fixing R10: The Rev. A printed circuit board has an error in the connection of R10. If you plan to use R10 to key a handheld, you will need to cut a trace and make a connection to the drain of Q4. The diagram below shows the trace to be cut and the connection to be made.
