I would like to connect my Universal to a flight instrument that supplies serial output (glider vario with GPS, altitude e.t.c. information).
I have seen RS232 cabels with converter to USB, but my question is - will this work or do I need a driver for my Universal?
Has anyeone tried this with succes, and if so, what was the solution.
Best regards
Steen
I forgot to add, that I would prefere a solution where the converter is not build into a RS232 plug, as the serial input would com from a Hirose p/n HR10A-7P-6P plug. Therefor I wil have to make my own cable - at least on the serial input side.
Serial connection from Universal
I don't think you can use the USB connector output and convert it to a serial formal as the equipment needs the ability to behave as a server for the serial connection, whereas it is only configured to act as a host (i.e when connected to a PC). (terminology may be incorrect ...!)
What you could obtain is a Bluetooth Serial port .. i know you didn't want the 9 pin plug, but you could easily make yourself a connector -and it would work wireless.

I'm currently using a Samsung MITs-M400 PDA-phone which runs the Korean edition of Pocket PC 2002 Phone Edition. From the 19-pin connector on the bottom of the unit, the battery charge and USB connecton pins have been determined after cracking open the cradle and some 3rd-party data cables for this device, but the serial port pins are still elusive. Samsung does not intend to release any specifications relating to the port (but then again they don't even release SDK for the internal camcorder and TV on the device, so we're used to that), so I'll have to try finding out the hard way. Trouble is, there is hardly any device on the market that uses this port. Is there still a way to determine which pins are assigned to serial connection? I'd appreciate any help.
Use a program that opens the port (after killing ActiveSync) and try to figure out which pins are high impedance by hooking a 10k resistor to ground from the tip of your multimeter. Anything that measures 5v under these conditions is an output that is driven high. Now hook the end of the resistor to 5v instead of ground, and repeat measurements. Any pin that is now 0v is an output that is driven low. Remaining pins are either inputs or non-connected pins. Experiment from there and you will find it.
Alright, thanks for your input.
This has been asked on here before, but no answers....
Is the serial port on the BlueAngel RS232 or TTL?
If it's RS232, does it have the power to drive a MAX232 style adapter off the connector, or will I need external power?
Does this exist? I'm about to purchase an HTC P3300 and I would like to use a car diagnostic software call "VagCheck". To use it, you need a cable to connect from the the PPC to the cars OBDII port. These cables only come for iPaq ppc connectors to OBDII, serial to OBDII, and USB to OBDII. These cables are expensive and I already have a serial to OBDII cable. So I'm looking for some kind of way to connect the cable to the P3300 via the mini USB connector but I know there will need to be some drivers involved.
Does anyone know if there's an adapter from mini USB to regular USB or Serial for PPC's with drivers?
BTW, there is a more expensive alternative. There's a bluetooth connector for the car that plugs into the OBDII and you can just connect via BT. But that is the most expensive set-up.
USB to serial
I guess you can use USB to serial converter, which is inexpensive.
Thread moved.
AFAIK the P3300 is USB client only, which means it can only be used as a client device to a PC. USB host capability is required to work with USB peripherals such as a USB to serial adapter.
So basically what you are trying to do won't work with the P3300 unfortunately.
The only way around this problem would be to get a bluetooth-serial module which would connect to the serial - OBDII unit and allow the P3300 to connect to it via bluetooth.
A bit silly I know, this is the result of most PDA manufacturers choosing not to equip their devices with USB host capability.
Antzzz et al,
You're right.. The current HTC range are all only USB Client.. So you can't connect an HID device, serial adaptor etc.. There IS rumoured to be a set of serial pins on the non-standard Mini-USB style connector on the D810 device range - however, we've never seen a cable that breaks out (or explains the RS232 pins)..
Does anyone have a full pinout of the extended connector??? This might be a project for further investigation.... ?
There are a few industrial RS232 to Bluetooth adaptors, such as :

But they're expensive as a rule.. You may want to grab a Bluetooth OBDII interface.. (or another cheap PDA with RS232 like a cheap low-end iPAQ hx2490).
Let us know if you stumble across the RS232 pinout on the extended D810 connector.

i am having the same problem. i have a xda orbit with some software on it to adjust my air suspension on my car. i have tried connecting the cable supplied with it to a serial lead and then the obd11 lead but i could not get it to work. just found a Original O2 XDA Serial Sync Cable . ordered today from
http://l8shop.net/products/Original-O2-XDA-Serial-Sync-Cable-3280.asp
if you have any success in getting yours to work i would appreciate any help.
hi, been looking at obd software for ppc, and been wondering if i get a adapater to fit the cable into the mini usb socket if i can use the device on my phone?
i've read phones with serial ports can do it, but not with usb obd readers, also does anyone know if any phone out can do if if this one cannot?
cheers!
Quite a lot PDAs supporting USB-host, but for only a few an adapters or appropriate cables from the manufactures are available.
As these devices support USB-Slave as well I would like to know if there's a way to convert the USB male connector (used as slave e.g. for sync with the PC) to a USB-host female in order to connect accessories (keyboard, mass-storage devices...).
According to wikipedia the configuration of the pins shouldn't differ too much for slave and host mode.
Pls. see attachement, that's what I found regarding this question. It's a picture showing a similar configuration (as new user I'm not allowed to post external links, thanks to ab21cn
from xdaflameusers)
But it's a male-to-male converter and furthermore a converter from "big usb" to micro (mini?) usb. As there're already standard converters for the different sizes of USB I would like to start with the biggest size and to buy the appropriate converter as needed.
Does anyone has a circuit diagram or any other idea for such a generic converter?
Try adapters made for Nokie N800 series
I had a Nokia 770 a couple of years ago. It came as USB device only with mini USB connector, but online I found how to upgrade the software to USB host, and use a cable adapter. The plans I found online involved a 9V battery and 5V voltage regulator inside a metal case (they used a penguin mints case). I built one of those, even using the penguin mints case, and it worked fine.
I have never seen any indication that my HTC phone would work the same, but I am guessing that it might, if the USB host drivers are available.
Google couldn't locate the penguin mints-based converter I originally found, but this seems to be a similar circuit diagram.
Edit: Found it!
thx
thanks for the links. but i'm a little bit afraid of connecting something to my pda which has an own power supply, the risk of a burn-out is given. i've got a nautiz x5 with 4400mA battery which should have enough energy to supply usb-power to connected devices.
I think I'm going to contact the manufacture of my device, maybe this works for me, but a generic adapter would be of use for anyone.
the chips used for usb should be of the shelf as i don't think each manufacture develops an own logic for usb... but this doesn't imply that the cabeling is standard too.
what the heck makes manufactures providing features in their products which the users can't take advantage of?
do you mean using keyboards and so on on ppc?
because it's so simple if ur phone has a mini usb plug (the one u plug the power adapter into). i found a cable that plug into that and plugs a normal usb cable in on the other side and blam been typing on my phone using a desktop keyboard. it depends how much power your device requires however. i wish there was some software to feed a video line out so i could watch videos on pair of vizors that wud be rad. all i can find is a mini-sd card converter now whats the point of that. guess i need an itouch
yes
primary i want to connect usb mass storage devices to my pocket pc. gamecontroller or keyboard would be a good thing too.
my devices doesn't have a standard usb plug, the only thing i got is a adapter from the properitary plug of my device to standard usb male connector, but this is meant for usb-slave use only.
the underlying qeustion is, if there's a way to convert usb-slave to usb-host using the same pins. if it needs an additonaly pin then i don't see a way to convert it as i don't know anything about the pins cableing of my properitary plug.
a week ago i found an adapter which was able to convert the male usb to another male usb... but it didn't work.
the problem is compareable to datatransfer between two pcs via usb - it's possible, but only using properiatry hardware and drivers...
so i think there's no way to solve this problem in a generic way.
out of interest, do you already have windows CE drivers for the device to act as a host and mass storage? I wouldnt mind them if you can point me somewhere..
how to check if my htc (touch2) ca use usb host?
