GM380 accessory socket

[gm7svk]

Hi, can anyone give me a source for, or list here, the functions of the 20 pins on the accessory connector on the back of a GM380.

In particulat looking for the COR/COS signal pin, whether active high or low and the voltages which should be seen on the pin in both states.

Thank you,

Thank you Dave, unfortunately no go. That arrangement is for programming. Looking for the 20 pin rear connector pinout. I have some of it but not all. In particular need information on the COS/COR operation as the voltages I am seeing do not seem to conform to the normnal +5v or 0V. What I seek is the equivalent of the the GM360 rear details, they however do not match with the 380...oh for consistency?
