USB on the option board

Hello,

First off all, congratulation's for the gps.
Now my question :
Has anybody figured out where are the usb pins on the option board?
I need :
Bt usb+
Bt usb-
5 v
gnd (that i will find on myself i suppose )

If possible on a picture please, thanks

greetings

 

Looks like on SN18:
BT_USB+ (29)
BT_USB- (30)

I dont see 5v on the connector.

Modly has the manual at:
http://modly.net/CF-28/Manuals/

 

Check my last post (after adding the manual URL)
I've got to stop that repedative editing thing....

Check page 191

 

That was dicussed already on aftermarket gps thread and cn 18,go back and read those thread first. I am the only one and stan. dist.. has an interest on that before. I used usb internal line for gps and bluetooth to my cf-m34 and now on cf-28 with 32 channel usb gps also builtin.

 

Then you may have lots of undocumented experience you can share with denrosten on this thread.

 

First of all i am the guy who introduced first the 3com combo modem on cf-28 thru ebay. I am not yet member here and Gravitar ask about a couple of Q? with regards to that combo modem and he invite me to join on this forum. Right now I've seen a couple of seller selling the same stuff on ebay.And here I am

and here is the link the first combo on ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330167342622

That was 5 pieces and selling just blink of an eye and somebody keep asking if it really works.

 

I know the pin out of cn 18, but is there a place on the option board to solder the wires for the hub on? (with more space than 0,5 pith)

Thanks

 

3com combo card?...and? Whats that got to do with what I just said?

 

denrosten, I'm not sure about that, perhaps Olip knows...

 

Nice to meet you Ohlip, you did a great service to the CF-28 community by introducing that card

 

Best answer I can provide is to break out a multi-meter. Right now I'm backed up on projects badly. Tonight when some things calm down a bit, I might see if I can trace some pins though.

A very stressed out guy named George who needs the hearse to be able to drive 2500 miles in 10 weeks, and it currently has a blown transmission.

 

Thats the big Q? now will going to find out if u can solder a wire with only .5 pitch. I done it so many times. Its your turn now. The option board has a lot of space even if the gps engine module(408) already in place, enough for 2 or 4port USB hub and maybe another for usb bluetooth. Its your choice

 

Not me, man! Its Gavitar..

 

I'm not sure if I thought of it first or if ohlip did. regardless, ohlip deserves his props for being one of the frontrunners here. as long as we're all actively experimenting and reporting our results to the group, everyone benefits. a lot has been discovered (and shared) in a very short time here, hopefully we can all help to maintain the momentum!

 

denrosten-
scan through the 'Adding aftermarket GPS' and 'cf-28 internal port CN-18' threads. There is a lot of info there, especially in the early posts - first 2 or 3 pages. I think toughbook mentioned a couple of pin locations for power (3.3v and 15v) and that there was a 5v source as well on the board.

Hopefully this will give you some help.

 

I don't have the board yet, i bought one of Xtratuff (see Adding Aftermarket Internal GPS to the CF-28)

I was hoping somebody know where is the usb on the board so that i can drink "Belgian" beer instead of looking on it with a multimeter.

If anybody has seen the pictures of Xtratuff, the module on top of it, is that a wireless modem? and if so, is that a sort of pcmcia slot?

Perhaps usb is also on this connector (cn103)?

I am not using cardbus A (doesn't work on mine) so i am going to replace it by a 4 port usb hub inside, that's the reason why i need the connection on the rim board for.

Greetings

 

As far as I remember, stan.distortion is the only one that has really pulled USB off of the connection. The board itself does not have USB as such, but used the wireing description of the CN18 connector to find pins he could pull from. Search for some of his posts or CN18 and see what comes up. It's probably buried in one of the huge threads on the connector or adding GPS.
It is a wireless modem PCMCIA type card (at least the CDPD type on mine), but it uses specific connections to handle the communication, through another flex cable that connects the board to the card. The CDPD uses only 22? of the available wires. The 50-pin cable has assignments for USB, power, serial, status of the possible board add-ons, etc.
Check out the service-repair manual on modly's site - look for the CN18 connector on one of the pages toward the end.
Except for stan.s..., most of the work here I think has made use of the existing solder points for the GPS option to add a GPS module to the board. There has been talk about getting a breakout board developed, but I don't think that has come about yet. stan, ohlip,toughbook,gravitar (did I forget anyone?-sorry [oops - modly]) seem to be doing the most on this.

 

Thanks Kilbo,

The pin out on cn18 is easy, but it is so damn small to solder on.
cn 103 (on the rim board) to the modem has much bigger connections, so i hope there is also usb on (anyway i am going to find the connections)

Regards

 

I've just spent the last hour trying to trace the board out.

The BT_USB+/- pins end within a quarter inch of the CN-18 connector.

It's slightly easier to solder, but not much.

Sorry mate.

 

hello,

I did some homework for the usb pin out, en the only wan i could find was these (see picture)

 

I think it's nice of Pana, or their suppliers, to put tick marks every ten pins on their connectors. I don't think I've seen this on the (admittedly few) other boards I have looked at.

The 'Aftermarket Accessory Board' thread has some related info, and more on 5v and 3.3v outputs.

And stan.d... put an incomplete pinout at
http://forum.notebookreview.com/showpost.php?p=2721498&postcount=80
that maybe a little easier to read than the repair manual.

 

I'm slowly getting work done, but right now it's almost ready for prototyping. The prototype WILL have USB on it (In addition to GPS), however the prototype will not have a proper connector for GPS modules, so we'll have to do it like we do now and solder through holes. I've gotta verify I didn't make any mistakes before sending out for boards to be made. Keep in mind, I may want to add protection like resistors in before I get the thing made up, so it'll be another few weeks in the CAD.

Once I clean it up a bit, I'll send off my .sch file for anybody involved here to look at (Don't want just anybody to grab it and think it's done and make a board then yell at me, or have certain people on eBay to have it either ).

If there is something important you think I should incorporate into the first release board, let me know by mid February. If it's small enough, it'll get put on, but the first board will be very basic.

 

can you put a current regulator on the 5 v line of the usb?

Derick

 

I can add a spot for a resistor if you'd like. That's pretty easy. Finding the value you'd want though is the hard part.

I suppose for safety I should add a resistor to every +v source.

 

denrosten-
Just checked the SB300 spec ( http://toughbook.wikispaces.com/space/showimage/sierrawireless-sb300-2110049.pdf)
Pins 23 & 24 are marked as 5v for the 30 pin hirose connector for the modem. Also 25-28 are ground. This might offer a better solder point for pulling the power to the USB.
[Edit - realized that the 30-pin is also .5mm pitch. Looking for specs on the RIM modem to see what power comes to the larger 22(?)-pin hirose for that.]
I took the plunge last night, since I have a few extra daughter cards, to try my hand at soldering to the break out points for USB+/USB-. Surprisingly enough, it went well using 30-guage wire, considering my lack of soldering skills. Will try for the power point tonight, and see if I can drop a small USB hub in the space somehow.

 

Thanks Kilbo,

There are indeed 4 better solder points at this place for the 5v, and i even think there is a current limiter to 850mA on it.

I am going to check with a multimeter the voltage on that spot, and see if it is switched or not

Do you have the jumper settings for the modem? because i think there be only voltage on it if the modem is enabled by the jumper and in bios.

Greetings

Derick

 

IIRC - [switches] 1&2 are on for CDPD, 1&3 for RIM, 4 for GPS, although I think someone said that the switches are only to let the BIOS know - they don't really control power to the modems/GPS, basically just ground the line I believe. I also think that switch 1 has something to do with the front wireless on/off switch.

 

Modly... Do you want me to ship out the 50 pin connectors for the ribbon cables? It would require some precise soldering but I think it could be done. The soldering guide on hackaday shows it to be fairly easy.

Anyway... Let me know if you want them. PM me your address and I'll get them out to you. I think I ordered 20-25 of them.

 

Unswitched 5v seems to run to a solder point below C123 on the 'bottom' of the daughter board. Switched 5v (pins 40&41) appear to connect to C122. Can a solder connection be made to either side of that?

And pns 23 & 24 of the 30pin (to SB300) connector appear to tie into C102, C110, and empty C111 on that end of the board.

Would any of these be good 5v sources?

 

I would solder on the other side of the resistor (so the power is "filtered"), but it could be done.

I would still trace it out more to see where it ends up, and see if you can solder on something easier to solder to.

It'll be Wednesday before I am back in town to check that out, but if you haven't found a 5v source by then I'll look.

 

You guys are amazing! I truly wish I could follow half of this thread...I do try.
