Tunze 6055 DIN pin assignment

[Metal Man 1221]

So I have recently acquired a Tunze 6055 with the intent to control via my Apex. Now instead of buying the $20 cable, I have opted to make my own cable as I have plenty of ethernet lying around and this kind of thing is right up my ally.

After making the cables according to the unofficial Apex user guide, the apex did not have control of the Tunze. After opening the enclosure on the Tunze to examine the female DIN jack, I noticed that the user guide had instructed the improper pin assignments for the male jack. After re-soldering the signal wire to the correct pin I gave it another try. Still a no go. I noticed there is also another wire on the Tunze female jack, which I read was an 8v out for the Tunze multi controller. Thinking that maybe I had gotten the signal and 8v confused, I again re-soldered the signal wire to the corresponding pin.... still no go.

I am pretty sure that the Apex is functioning correctly. The variable speed port LEDs are flashing at the rate that the pump is to run in the profile I assigned to the port. I also set the same profile to both V1 and V2 with no luck. I was thinking about testing the ports, but I don't have a multimeter any more.

Just curious if any one else has had the same problem? At this point I'm leaning toward the problem lying with the Tunze.

Thanks,

Just tested the variable speed ports with a small 12v computer fan. All is well on the Apex end and up through the cable.

I hope you didn't damage anything by connecting a fan to the VS ports. The VS ports can only handle a load of several milliamperes. They are not intended to provide power to anything - just a small control signal.

 

[Metal Man 1221]

I don't think I did, the fan is quite small, and I only had it on briefly just to verify I was getting a signal.

I looked a little closer at the Tunze and the problem was with a bad solder joint. A little heat and some tin and lead later the pump was pulsing away.

So on my tunze its a weird looking port (almost like ps2 or something) did you just open that box up and solder it there and then rj45 on the other end?

 

[Metal Man 1221]

The port you speak of is a DIN 5. When I opened up the box on the Tunze there was a bad contact point that I had to resolder. If you go <a href="http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CC0QFjAA&url=http%3A%2F%2Freeftech.webs.com%2FApex%2520New%2520User%2520Guide.pdf&ei=RWZnT6z9D8WSgwfe0d3qAg&usg=AFQjCNEeJiDQ1oyIOIH8fw54WykxTou_mA">Here<a> the unofficial user guide will describe how to solder a DIN 5 male jack on the end of your ethernet. Your probably won't want to directly solder your cable to your Tunze.

That guide is awesome - I didnt see the tunze powerhead cable creation though, only tunze dimmable lights?

 

[rhwimmers]

Also, are all the tunze's the same? I have 2 6105s

 

[Metal Man 1221]

The Tunze pump cables are on page 68 just above the RAMP section for the lighting. The 6055 (the pump I run) is supposed to use pin 1 for the signal, but as it turns out it ended being pin 5, which I believe is the pin used on all of the Tunze pumps.

I was reading the guide today and notice this and was a little confused. in the writing for the pin out if says on the male end it's clockwise 1,4,2,5,3, but on this picture it's showing the female side with the same order. Wouldn't that be reverse on the female side? I am getting a used 6100 and want to make sure I wire it correctly. Good write up and troubleshooting Metal Man.

 

[Metal Man 1221]

You are correct, the documentation for the pin arrangement is incorrect. It should have stated that the <b>female</b> jack pins are numbered clockwise 1,4,2,5,3. The male pins are the same, but in the opposite direction.

Like this:

---------------------------------------------------------------------------------------

After doing some looking, they were in fact not wrong by saying the pins on the male jack are numbered clock wise 1,4,2,5,3. It is just the picture that really contradicts the statement. Which is IMO more problematic for a lot of people because (like me) they are visual learners, and will turn to visual aid when ever possible, ignoring written directions if the visual ones are sufficient. But I suppose in this case.... They aren't.

Thanks

Im a little confused - I went and got the 6' 5-pin din cable (on each end), cut it in half, then one end gets a rj45 plug. I understand I just need to run the cables in 1,2 and 5,6 - right? This cable I just get a yellow black red and white from it - which ones go in which position?
TIA

You will need to use a multimeter to determine which wire corresponds to each pin on the DIN plug.

Do you have a RJ45 crimp tool?

You could take the easy solution, and just order the right Neptune cable.

 

[rhwimmers]

Yeah, got a crimp tool - i'm an IT guy # ; )
I guess I thought someone already knew which colors were which voltage. So 2 of the 4 wires will give me 0 reading (ground) and the other 2 will give me 10vdc...whats the v2 and v4 and v1 and v3 mean?

The wire-to-pin mapping may vary depending on what that cable was intended for. You said it only has 4 wires, so it is not fully wired - it may not even have wired on the necessary pins inside the plug. As I said, positively identify which pin matches each color wire using a multimeter to check continuity.... that's the only way to be 100% sure.

Just checking about the crimper... I've seen people try to use a small flat screwdriver to push down the contacts in RJ-series connectors and other crazy improvisations... usually with dismal results.

V1/V2/V3/V4 mean Variable Speed ports. See page 69 of the unofficial New User Guide for more info

So would it look like this?

 

[Metal Man 1221]

Nope, 1 and 3 are used. So your White Orange and White Blue (1&5) on your ethernet will be your ground and your Orange and Green (2&6) will be your signal wires. On the DIN jack pin 2 will be your ground and 3 will be your signal wire.

mixer - excellent pic! Much appreciated!

but it is wrong.

Pin 2 is the ground
