Help with RJ12 to RJ45 lead to connect the SynScan WiFi

[bsf 11]

Hi everyone,

I hope this is the correct place for this post. 
In terms of DIY my post might be stretching it but it the closest section I could think of to post this.

I brought a SynScan-Wifi for my GOTO mount for WiFi so I can use my SynScan app rather than the handset. It is a Skywatcher skymax 127 AZ GOTO telescope. The SynScan-Wifi has a socket for a RJ45 while the mount  has socket for RJ12. The SynScan-Wifi came with a lead to connect up but the Wifi was intermediate and unusable. So I got rid of that flimsy lead and used the long Spiral coiled handset lead that I already had and I have no problems. 

But I want to get a shorter lead to avoid wires everywhere. So I brought a 0.25 cm lead but when I connected it up there was no signal no yellow/green data lights flashing. The lead was inexpensive but the right type RJ12 to RJ45. The shorter lead that came with the product was unusable and now I buy a separate lead and it still does not work only the longer handset lead works.

To avoid me buying lots of leads to try out does anyone use a short working lead to connect the SynScan-Wifi to their mount or would anyone recommend a quality one to connect the mount to SynScan-wifi.

Thanks in advanced

Bob

Take your long curly lead that works.

Look at the two ends placed side by side with both clips at the top or bottom.

Look at the wire colours - do they read the same, or is one reversed ?

So eg R O Y B  and  R O Y B

Or R O Y B  and B Y O R

Now do the same with your new lead - is it the same as the good lead, or reversed ?

Cables  can come as Straight Through, or as Reversed.

Hi Michael,

Thanks for you reply.

The RJ45 end is reserved and my new one has extra black and white.

So working one sequence is -  R G B Y B

While the new working one is -  B Y G R Black White

To buy a working RJ12 to RJ45 lead for me which colour sequence is reversed, when I was buying one online I do not recall options on colour sequencing - it just said RJ12 to RJ45.

Thanks

It's only the wires on the 4 pin end that are relevant, as the extra wires on the other end aren't connected at the 4 pin end.

Perhaps you should contact your local astro store for the correct Skywatcher cable.
