JBC soldering iron stand wiring foot pedal
« on: February 27, 2016, 11:29:19 am »
Hi, Please forgive me if I have posted this in the wrong place, I am looking to find out the type of connector on my new jbc soldering station so I can connect a foot pedal, It has a roughly 10mm diameter thread on the outside to hold it in place and an internal bore that seems to accept and hold a 3.5mm jack type audio plug. I have not checked but assume it only uses two poles as its just a switch. If anyone recognises this I would be grateful, I recognise the other connectors on it as binder brand already discussed on here. Thanks Robin

Seems like lockable 3.5 mm jack. http://cpc.farnell.com/1/1/14158-pro-signal-psg08275-3-5mm-jack-plug-locking-stereo.html
You can use a usual jack connector as well.

Hello,

Did you, or can someone, confirm that the pedal is indeed only a switch (so no electronics is inside)? So any other switch will work.

Nope, definitely not just a button. I have a hot air station from them with one of those ports, and no matter which connection you close, it does nothing.
I get +2.3V ground-tip and +2.3V ground-ring. some weird fuckery going on there.
they're either using some signal to check for an actual pedal, or just a specific resistance value in-line with the switch, idk.
It's be nice to get someone who has such a pedal to tell us what's inside it.

Bit of a massive thread-bump from the past - but has any ever managed to reverse engineer the JBC foot-pedal?

Even if someone had one, and monitored resistance values when pressed, etc - or similar.

They seem quite highly priced for what should be a simple switch - does anyone have any insights here.  Do they actually have more smarts in them than a simple switch?

Its not an answer but someone has drawn a schematic of a jbc station here:
https://www.eevblog.com/forum/testgear/jbc-soldering-station-cd-2bc-complete-schematic-analysis/

The sleep signals are pullups that need to be shorted to ground. Its surprising if the foot pedal is using something other than that.
What about opening your station and seeing where the inputs go?

Alas, that schematic is for a model that doesn't support any pedals!
I took apart my electric suction module (which has a pedal port to it) to try an see how the hell this stupid port is wired. Took some pics along the way!
Basically, it's wired to two digital I/O ports on a PIC24HJ256GP206.
so it's either talking to the pedal to identify it as such, and asking it its status (pressed or unpressed), or I'm a jackass who can't even short out three wires together  :-//

I guess the only step after that is to wait for someone to loan/buy one and have them take it apart to see what's what.

Quick update for those still interested in adding a pedal to their setup, one option could be by using the robot control and protocols to control temperature, on/off cycle, etc.
