[1000mp] FAS-1-4-R and fl7000

[Paul R]

Howdy,

Getting my new station together and looking to to get my Yaesu antenna 
switch (FAS-1-4R) linked up to the fl7000. As I purchased my switch second 
hand I do not have a scematic for it. The fl7000 manual shows that the 4 
wires coming from the din on the remote ant switch connect to 4 contacts on 
the back of the amp marked "A,B,C and Ground". The din plug at the ant 
switch end however is simply marked pins 1,2,3 and 4. Can someone advise me 
which din pin goes to what contact on the fl7000.

Thanks
