The + pin of the DB102 is on the bottom right both of the ~ should be on the left.

The jumpers on the board are for 120/240v operation. If you don't plan on using the boards on 120v these can be hard soldered with a jumper wire.

PC to Renard24 LV Cable

PC DB9 Pin 3 to RJ45-pin 4
PC DB9 Pin 5 to RJ45-pins 1,2,5 (pins 1 and 5 are required, pin 2 is optional).

If you are using a RS-232 to RS-485 converter, the pinout is Pin 5 to A+ and Pin 4 to B-. This is the same as for the Ren 16.

Female DB9 connector as if you were looking into the end of it from the outside.
