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.  After ten minutes the LED will turn solid red and the ID-O-Matic II will beep at you to remind 
you to ID, then automatically reset and begin a new timing cycle.  The open-drain PTT output can be used 
to drive an external indicator such as a lamp or LED.  Push the RESET button to begin a new cycle any 
time you ID. 

 

Auto ID mode: 
Similar to the simple timer mode, this will send a Morse ID at regular intervals.  The INHIBIT input can 
be used to delay the ID if needed.  Note that two Morse outputs are provided; there is  CW output that is 
used for on-off keyed devices (CW transmitters, etc) and an audio output.  The PTT signal is also active 
in Auto ID mode.  The ID message will be sent every time the ID timer reaches zero, and the timer will 
automatically reset and begin counting again.  This can be useful for “fox” transmitters, beacons, etc. 

 

Repeater mode: 
In this mode of operation, the COR input is used to indicate that the transmitter has been keyed.  It is 
normally connected to either a receiver COR/COS or squelch output, or to the PTT line that would 
otherwise be connected to the transmitter.  When the COR input first goes low (active), the PTT output 
line is immediately activated.  The ID timer is loaded with your specified ID interval and begins counting 
down.  At this time the LED will begin flashing green.  When the ID timer reaches 60 seconds, the LED 
goes to solid yellow.  At 30 seconds, the LED begins alternating red and yellow until the timer expires.  
At that point the LED goes solid red and the ID message is sent.   The yellow and blink times are 
configurable using the setup menu. 
 
If the interval since the last ID message has been longer than the ID interval – for instance, if your ID 
interval is set to 10 minutes and the repeater has been idle for more than 10 minutes since the last ID -- an 
initial ID will be sent 10 seconds after the first time COR goes active.  The ID timer is then reset with the 
normal ID interval.  During this phase, a “polite” ID is used; the ID message will not be sent until COR is 
released OR the normal ID interval is reached. 
 
The INHIBIT Line can be used to hold off the ID until the repeater is not busy.  As long as INHIBIT is 
held low, the ID message or beacon message will not be sent.  As soon as it is released, any pending 
message will be sent.  The only exception to this rule is if you have PTT MAX (time-out timer) set; the 
ID-O-Matic II will send “TOT” (for Time-Out Timer) and its ID message when the PTT MAX timeout is 
reached, regardless of the state of INHIBIT. 
 
The PTT output is always active when the ID or beacon message is being sent.  It is also active: 

 

If PTT hang time is set (not zero), the entire time COR is active plus the length of the PTT hang 
time setting; 

 

If a courtesy beep is set, the entire time COR is active plus half a second and the length of the 
courtesy beep; 

 

If both are set, the entire time COR is active, plus the courtesy beep and hang time delays.
