Can anyone tell me what the jack by the label on this 2006 is for ??

A company in Batesburg, S.C. called A.I.E. used to sell tone decoders, and
would also do installs of the discriminator and memory interface.

They commonly used cat 5 connectors for the line between the decoder and the
scanner, with female connectors mounted about where the one is in the picture.

I have two 2006 scanners and two A.I.E. decoders - model TCF4 - mated at home.
Both were done the same way. A.I.E. sold me both the scanners and decoders, so
all I had to do was place the order, and they were shipped ready-to-use.

If the connector in the picture was not used for an A.I.E. decoder, I presume
it was still used for a discriminator tap.
