Because I can't find good picture of socket, you need to rotate your PLC counter-clockwise - then numbers of pins will be OK.
Rx pin is pull-up'ed to +5V
For conecting to PC you need simply converter on MAX-232, only rx,tx are used.
After powering up PLC, Rx pin is Low about 3 seconds (lcd of plc is blank) , after that - is pull-up'ed.
Model easy 619 from moeller, works (comunicate) with free Allen Bradley PicoSoft :)
