Geoff, an Rj45 to DB9 adapter is the way to go, do away with the standard curly cord altogether, but needs to be configured correctly for the EQ6. I've made a couple from time to time, I fairly sure I have one. When I get a minute I'll check to see what pinout it is without reinventing the wheel.

OK found the time, much to HRH's chagrin.

This should be correct, all care taken no reponsibility. I made a couple of these, I remember one went to h0ughy.

You should only need, fingers, eyes, an adapter, perhaps some pliers and preferably a multimeter.

If the pins are already fitted to the DB9 Male adapter (e.g. Second hand), you'll need to gently push the pins out of the socket with some pliers, try not to squeeze any harder than is necessary or you'll squash the pins; you can also use a blunt object to push the pins out.


If you get one with the pins not fitted that's even better.
Pins on the DB9 number as follows from the front 1-5 and 6-9 are left to right.

When you fit/re-fit the pins make sure they click in to place, if necessary use a straightened paperclip to push them home.

The RJ45 socket pins numbers 1-8 from left to right looking in with the notch down, you may wish to either check with a multimeter or visually to confirm you colours match the ones listed below.
All RJ45 to DB9 connectors I've seen use the same wire colours on the RJ pins.

Pin 1 Brown = Pin 7 on the RJ
Pin 2 N/C
Pin 3 N/C
Pin 4 Red = Pin 4 on the RJ
Pin 5 Blue = Pin 1 on the RJ
Pin 6 Yellow = Pin 6 on the RJ
Pin 7 N/C
Pin 8 White = Pin 8 on the RJ
Pin 9 Green = Pin 5 on the RJ

A final check, plug a standard cat 5 cable in to the adapter you have just configured and compare the pin for pin end for end continuity with your old synscan cable, you may need to wrap a pin around you meter lead to access the RJ pins on the cable end.

If you're going to use the joiner listed, to extend your existing curly cable, check the final result with a multimeter just in case, the assembler who put the thru connector may have been having a bad day.
