Hi everyone, I have a SLC 150 and i need to download the program, but the problem is that i don't have the cable for making the connection from my lap top to the SLc 150.

Could anyone halp me to built the cable????

I believe the SLC150 uses a RS232 to RS485 convertor, there are suppliers for this if you cannot make your own, B&B for example.
I also found this.
Black Box Corp. Model 800 A or B Hookup to a SLC 100/150 Allen Bradley PLC.

Allen Bradley connector Black Box Corp. connection

pin 2 RXD- --------------- TXD+
pin 1 RXD+ --------------- TXD-
pin 3 TXD- --------------- RXD+
pin 8 TXD+ --------------- RXD-
pin 7 GROUND --------------- GROUND

The connections are transposed on the Black Box Corp. end.
The Txd+ goes to the Rxd- on the A-B Side.
The Txd- goes to the Rxd+ on the A-B side.
The Rxd- goes to the Txd+ on the A-B side.
The Rxd+ goes to the Txd- on the A-B side.
