Accessory Decoder [AD4] Main Line (OPS) Programming
Accessory Decoder Factory Reset
Direct verification is used when you want to check a CV for a specific value when the AD4 is
connected to the main track. The procedure is similar to writing a CV and in fact that is where you
start. Only decimal values may be verified on the AD4.
You must be able to see the red ACK LED on the AD4. This LED is your only indication that a
verify has occurred. For this example, decoder number 10 will have CV515 verified to contain a
value of 0.

m OPS PRGM this indicates that programming commands
will be sent via the main track. The (<512) reminds you that you
are to specify the decoder card number, not an output address. The
decoder card number is between 1 and 511. For this example card
number 10 will used.
m 1, m 0, m ENT
m 5, m 1, m 5, m ENT
m 2 select 2 to verify the desired value in CV515
m 1 select 1 to verify a decimal value
m 0, m ENT Only push ENT when you can see the card’s LED
If the value contained in CV515 is 0, the red ACK LED flashes.
This is the only indication that the value has been verified. The
value on the display doesn't mean anything except that the macro is
done. Only the ACK LED turning on (or staying off) is the valid
response.

Reset the AD4 to its original factory settings by following the steps below. The programming
track should be used for the reset command.
1. Use the programming track and program CV520 to a value of 0.
2. Disconnect the programming track and connect the decoder to the main track apply track
power to finish the task.
This two step process guarantees the decoder can finish the task of writing all of the CVs with
their factory default values. The write value must be a 0. The value is not stored and simply tells
the decoder to prepare to restore all factory defaults upon the next power application.
Be sure to use the main track for the subsequent power application. The programming track may
not stay on long enough for the decoder to finish restoring all the CVs.
You will know the procedure has been successful when, after connecting up to the main track,
you see the red ACK flash followed by the steady green status LED.
