- no Hardware flow control ( wires: TX, RX and ground)
at the Procede side you need a crossover cable.
That's about it.

Does the procede only use a 3-wire rs232 setup through a db9 connector?
If that's the case, then pin 7 and 8 needs to be tied and maybe 1, 4, and 6.

Yes 3 pins
2 o---------------------o 3 ( RD pin # )
3 o---------------------o 2 ( TD pin # )
5 o---------------------o 5 ( Ground pin # )

data bits, stop bits as well...

I used Portmon with a serial connection and all seemed fine but just could not get the PROcede to connect with that same Bluetooth adapter. It worked beautifully with some ASCII serial devices though. I had always planned on trying it again and may give it another shot this weekend.

Perhaps, but I beleive it ran on 9 VDC and normally there is a range. I wouldn't be suprised if 6 VDC - 12 VDC would be fine. The concern I had was the engine running 14 VDC it would see. Regardless, that would be easily remedied.

That was to be the next test with the IOGear adapter. However, using it with Hyperterminal back to the same or different PC worked fine. I just couldn't get this unit to work with the PROcede. But then again, I didn't try too hard either as my setup wasn't terribly difficult.

But then again, it would be nice to upload withouth hooking up a cable.

The IOGEAR is probably using hardware flow control. I think you are on the right track to simplify the null modem.

I would be cautious about running a 6V device off a 12V source unless you know for certain the input voltage range can swing that high without de-rating the device.

I dont know if this has been addressed with these serial wireless solutions on the Procede but...what happens if the serial connection is lost during a remap/reprogram? Analogous to yanking the cable off the Procede while in the middle of an operation.

munters · 10-17-2008, 10:16 AM

The Pagain works native with 12v this is one of the reasons Im using this one. and it is build for Industrial application (temperature)

On the PC side I'm using a normal USB 2 Serial without any cable between, but on the Procede side you need it. and it is DARN Cool to hook up wireless

The IOGEAR is using hardware flow control and will not work with a 3-wire rs232 interface through a db9. That's why you have to short out pins 7&8. I've been trying to find those db9 adapters with configurable pins. What are those things called?

Thanks munter --
Pin 7 and 8 has to be connected because the iogear will be waiting for a clear signal to send, but will never get it.. that is why I (and others) can't get this thing to communicate. Tying them both together will make the device look like it's always ready for data. The people in the robotics forums are running into the same issue with this very same blue tooth serial adapter.

I thought the procede is set up to run at 9600? I have my hardware com1 set to that and it works fine.

Why not go to radio shack and buy a female to male adapter and open the thing up and tie 7 & 8 together?

Great solution, munters

breakout box...OR you could get a simpler null modem that already loops back the handshaking.

I beleive the IOGear unit is 9 VDC, but will need to check.

The dropping of connection during and upload is a concern which I suspect we will need to test or consult with Vishnu about.

I was using my Internal Bluetooth connection.

Just wire up an adapter and if it works, let me know otherwise I will try and jump back on it this weekend.

scalbert · 10-17-2008, 04:17 PM

Since I am about 400 miles away from my car right now I cannot look. But is the PROcede connector a male or female? I am guessing female...

The one they had at radio shack is a solid piece of molded rubber so I didn't buy it...

Which msg? I think you suggested using a regulator instead of a voltage divider. If you did thanks man!

Ah, yeah breakout box. Difficult to find where I'm at. I couldn't find it at Fry's or RS yesterday.

5V@300ma.

I'll try to do this later today. I did short it out with a wire yesterday (pin 7/8), but that doesn't seem to work.

Procede end is a female db9.

Wow, looks like I was really stress testing it. I guess it only needed about 120 mA in my case.

Anyway, I'll still test again when I return home as I have to open the box anyway.

Yeah.... I like HighVoltage's idea of using a regulator. I think you can pick up a device to drop the voltage from 12v to half that at Kragens or other auto parts store...

Procede end is a female db9.

Gary

I would just get a hold of a couple db9 ends in the right gender(s) and put one together. Be sure to address both the CTS/RTS and the DTR,DSR and DCD. I didnt see you mention DTR, DSR and DCD. You may need to tie these together as well. Also, although unlikely it may be looking for the RI as well. In that case you may have to tie that to the DTR/DSR/DCD.

Just so you guys know, MicroCenter has this serial bluetooth device for $55 (discontinued)! It's a deal, esp if we can get it to work....
