Hi

I just bought an RJ11-DB9 converter & it came with no pins connected. There are six wired pins & 9 sockets to put them in. Can anyone help with a regular pin wiring for a DB9 plug please?

The wires are:
Red, Green, Blue, Black, Yellow & White.

The purpose of the converter is to plug a cash drawer (which has an RJ11 cable) into the DB9 serial socket in a pc.

Regards

9 pin D socket doesn't have a single way of wiring, it'll be down to the protocol used between the two devices. You'll need a wiring diagram to be able to connect them.

Thanks for your reply. I'll have to dig out some stuff about the till.

It may just be serial, should be in the docs of the till.

Thanks, I'm not sure there are any till docs though...
