Hi Greg!

Looking at the back of the Remote/Console connector (modular jack side that
is), with the locking pin slot down toward the floor, the number 1 pin
is to the left...


		Modular					RS-232-C

		1 ------yellow-------------------------- 1
		2 ------red----------------------------- 5
		3 ------blue---------------------------- 2

		4 --|				     |-- 8
		6 --|--------------------------------|-- 20

		5 ------black--------------------------- 3
		7 ------red/white----------------------- 7
		8 ------white--------------------------- 4

This is just like the ACU modem connector except for the short between 4&6
and 8&20.

As for the 355AF, this is a connector we use for our ISN to terminal
connections...  I'll try to draw it here in a simplified form, leaving of
the 'protection diodes' attached to pins 22, 7, 6 & 8 and 20.

		Modular					RS-232-C

		6 ------orange-------------------------- 2 
		5 ------white/blue---------------------- 3
		1 ------white/green------------/\/\/\--- 22
		4 ------blue---------------------------- 7
		2 ------green------------------/\/\/\-|- 6
						      |- 8
		3 ------white/orange-----------/\/\/\--- 20

		  ( The /\/\/\'s are 715 ohm resistors )
