Eqmod help please

DON"T buy the 3.3V !!!!

That link you posted clearly states that the 3.3V won't work !! Has to be the 5V

Not sure who I'm going to buy it from, there are quite a few places that knock out the FTDI 3.3v TTL usb cables/boards. I'm after some other electronics for a couple of projects so I may well end up buying it from where I buy the project kit from.

Reggie,

You need the 5V version of the FTDI TTL232R. The 3.3V version will not work as an EQDIRECT interface.

Thanks chris/Karlo, I'd just re-read the EQdir mod page and was about to correct my glaring mistake but you beat me to it

[themos]

The EQDIRECT-USB page says

To create the EQDIRECT-USB all theat is needed is to connect a 9 way "D" type plug to the flying lead of the TTL232R. The connections are as follows:

Solder Pin 6 of the 9 way D-type Plug to the Orange wire.

Solder Pin 9 of the 9 way D-type Plug to the Yellow wire.

Solder Pins 4 & 5 of the 9 way D-type Plug to the Black wire.

Can anyone confirm that both pins 4 AND 5 need to be connected to the Black wire?

TBH Themos it's been on that page for quite a while-if it wasn't correct it would have been flagged up on the EQmod yahoo group and changed by now. If it says 4&5 then that's what it'll be, I reckon.

I've just spent about an hour trying to solder the black wire onto those pins... I think I've ruined the Dsub connector, it's a fiddly job that I've never done before... a bit fed up now...

[beamish]

Don't get downhearted Themos ! Are you using a bit of wire to "jump" the two pins together??

It'll all be worth it, Honest !! Nothing worth having comes easy

Finished it last night with a solder bridge between pins 4 and 5 but it was too late to test it.

With a lot of help from Beamish and Reggie I have gone down th route of FDTI/TTL and connected the fly

lead end direct to an RJ45 and all seems OK sofar , just waiting for clear skies to try it out. ( For HEQ5 Pro )

It's what this forum is all about ! Cheers . Hope you don't have to wait too long

Sorry, I have only just seen this.

The way I normally create these dual connections is to use the wire portion of a simple resistor, solder one end to one of the pins, route the wire to where ever it needs to go & then solder the wire AND the cable at the same time.

You can even work in some heat shrink tubing if you want to be ultra-sure in keeping the connectors separate.

Works a treat.

Hope that makes sense?

[themos]

I have yet to try the cable. I will do continuity tests between all pairs of pins and wrap some insulation around the joints.
