Hi
Please excuse me being a newbie with a slightly odd question
Someone recently gave me an old HTC Himalaya to play with (O2 XDA II). The 'phone had been dropped and wouldn't charge up. Taking the battery out and charging it separately I was able to get the 'phone working fine.
I dismantled it to find that the 22-pin connector for power and data had completely detached itself and it fell out of the case. The pins were badly bent so I soldered power lines directly to the main board and it charges fine.
Now... what I really want to use this 'phone for is the heart of a vehicle diagnostics system (written in Pocket Zeus) so I need a working RS232 connection. I used Bluetooth to transfer a couple of test programs to the 'phone and they are showing that Com 1 won't open, but Com 2 and 3 will.
Can anyone tell me which ports the RS232 connections on the Himalaya match up to? In particular the port on the 22-pin connector. I can hardwire a 9-PIN D serial plug to this connection if I can get the port open.
Many thanks in advance and all help greatly received.

Does anyone know where I can buy the plug that plugs into the bottom connector for an XDAIIs?
I've asked everyone I can think of, searched Google, Maplin(UK) and Expansys and I can't find one.
It's probably because I don't know the correct name for it!
Ideally, I'd like one that has all 22 connections and even cables attached - they look really hard to solder onto by hand!
Any information would be greatfully received :lol:
Thanks

Wallaby, Himalaya are compatible with HP iPAQ Connector Plug Assembly (19/22/38/39/41/43/51/54/5500 Series)
but read that the plug of BlueAngel is not exactly the same.
I purchased an XDA II car charger from the O2 shop in Manchester - it came with a plug that works fine with my XDA2s - have used it on the car charger and on the supplied power lead - charges fine.
When I got my IIs, it CAME with the plug already, any standard car charger can plug right into that plug and then the IIs... You sure you guys didn't get it?????
I think you mis-understood me - I'll try again!
I have developed a complete installed car kit for XDA, XDAII and IIs that does the following.
Mutes stereo when in call and puts all sound to front speakers
Can put navigation commands through the stereo
Hooks up to external microphone
Has PS2 (Holux) and RJ11 (TomTom and Leadtek) GPS connections
Charges device
I'm trying to get hold of a connector with 22 connections because I have one problem left.
To switch the car kit on, I either need a 5V feed from the device OR need to be able to put 5V in on one pin and get 5V out of another.
If anyone can help with either the connector or letting me know which pins I might be able to use send me a mail please
Thanks

have you tried RS componets or CPC.?
Hi all,
My XDA2 was damaged by accident that the connection socket remain at the USB cable plug.. ..thanks for my little electronic devices terminator..
After open the case and I found the circult board was totally damaged and can't be solder it back definietly.
Without a connectivetly with PC, my XDA2 is definetly becomes a shoe-like-phone (or spare parts). Would somebody show me where I can jump the most important 4 USB data signal from the PCB?
Thanks,

I have a problem with my C550, I hope someone can help me:
A carcharger won't charge my phone. It senses the cable (screen goes from black to lit) but it won't charge. I use a motorola USB-charger, which worked on my SPV-M600.
I have the same problem with my PPC Techs Lil Sync USB AA Battery Adaptor I use on my bike.
The phone also won't charge on a PC without the proper software (active-sync?) installed.
I suspect it to be a software-issue in WM2003SE, maybe a registry-setting?
I have considered an update to WM6, but in that case I would like to backup the original rom that the phone now has, so I can revert to it. Can someone give me a link to a howto, or explain how to do this?
charger from motorola doesn't work with c550. i bought motorola charger to and it doesn't work.
I found an interesting message on spv-developers. The only thing then is how to do this. Pin 4 is not connected, so you can't connect line 4 and line 5 by cutting the cable and joining the two lines. Buying the C500/C550 car charger solves my problem partly because my lil sync remains....
I have solved the problem. I have bent pin 4 on my phone so it connects to the outer shell of the mini-usb-port (=ground). Now it charges off everything I feed to it.

Hi,
is that pin 4 as in the official pin 4 from the mini-usb pinouts so thats the far right if looking at the mini usb port with the phone facing down?
or do you just mean pin 4 counting from the left?
Hi there,
I was wondering, if it's possible to get a GNS Trafficbox FM9 connected to the HD2 (via adapter) to receive TMC-Data.
HyperGPS isn't working so far, so this could be the proper alternative...
Anybody's got some experience concerning this?
I've just bought a GNS Trafficbox FM9 which has come with a mini-B USB plug to use with my HD2. I've also bought a micro-b USB extension lead.
Taking the Trafficbox apart reveals a simple circuit board with the output wires coded in what appears to be standard USB colours. My thinking is that if I cut the USB A plug off the extension lead I should be able to solder them to the board and (hoepfully) away I go, avoidning all the traffic.
The extension lead should be here in a couple of days - I'll let you know how I get on.
Hi,
i have problem with wifi on my tg01 orange. It won't start. However it started twice after many attemps, when i tested this phone immediatelly after receiving, but later never again. I tested several roms with different radioroms. At this moment depending on rom version after clicking on wifi icon i have message "in preparation, please wait" or just nothing. Can i do something with it or it is hardware issue ?
What is more, after plugging headphones cable nothing happen. Does tg01 should autodetect headphones cable ?
Regards, Tom

Tom,
WiFi - Forgive if 'teaching granny'; use Wireless Manager to turn on WiFi. Then Start|Settings|WiFi Settings and you should get a display of any available WiFi devices. If nothing showing, tap 'Add New' to allow insertion of the SSID info for a known device and force a search. Are you able to check connectivity with your hub using another WiFi enabled phone or PC in the same location ? Assuming that works OK, try seeing if the WiFi adapter for that device can be detected by the TG01 in close proximity. If you are not getting anything at this point, then I'm afraid it suggests a probable hardware issue with the radio in your TG01. Depending on where/how purchased, you may be able to go back to the vendor if within warranty; alternatively it may be worth contacting the authorised Toshiba Repair Centre in the UK - Regenersis Ltd in Scotland. They would have the necessary facilities to test/repair.
Audio Output - the TG01 uses the newer micro-USB port standards. This defines a single port capable of multiple functions: Charging, Analogue Audio Out (+mic), Data (USB sync) and also USB Host capability. It does this under processor control by sensing the type of device being attached. One aspect is based on the resistance seen between the 0V pin and Pin 5 ( a special 'sense' pin). For audio output, it uses the resistance across the D+ and D- (Pins 2 and 3). If you plug in earphones or similar which have too low a resistance, it will not recognise them and therefore will not switch the audio output from the phone speaker to the uUSB port. The supplied audio adapter includes appropriate resistors. You can also buy simple uUSB to 3.5mm adapters which include or can make or adapt your own. There are references to this with more detail in this post in a different thread.
Good luck, and hope you are able to get the TG working properly
Regards,
Kevin
Thanks for reply.
1.wifi problem isn't in network search or connect, but in turning on. I can not turn it on. When i'm trying to turn it on i see "in preparation, please wait" - this is what happening on original orange ROM. Now i'm using miROM1_cfc and there is just no reaction when i try to turn it on.
2.headphones - i'm not sure that i understand everything. So if i will put 500ohm resistor between D+ and GND(0V) and between D- and GND(0V) and such a prepared cable i will connect to phone ,it will cause headphone mode ? if yes, it didn't work for me.
Is this specification of audio detection same for miniUSB and htc diamond ?

WiFi - It's pointing to hardware I'm afraid. But if you are willing to try another ROM, suggest try my WM6.5 edition (see link in my sig) and see what happens with that. It's using Radio 0300.76. If that also shows the same symptoms then I think you will need to look for a repair.
Headphones - yes should work OK. A baseline check would be to just plug in the supplied headphone adapter - does that work ? If so then there is nothing wrong with the phone and in which case I'd recommend checking you are using the correct pins on the uUSB plug and/or that there are no solder whiskers between contacts or similar (apologies if 'teaching Granny' here ). I'm not familar with any devices using a mini-usb in a similar manner - only one I've had with mini-USB was a Motorola RAZR3 but that was essentially just a 'dumb' hardwired USB port. The re-configurable approach only arrived with the introduction of the uUSB standard along with the TG01, HD2 and similar. Don't know about HTC Diamond, but in general HTC used a proprietary 11-pin connector which includes dedicated separate audio out as well as data and charging capabilities.
Best regards,
Kevin

No it isn't working that is why i'm asking.
To eliminate all problems that can be found at this headphone adapter i created special cable.
I used uUSB->USB cable (included with phone) and USB cable removed from mouse, so i can easily attach here resistor for test purpose.
And once again if i will put e.g. 500ohm resistor between D+ and GND and second resistor between D- and GND(no headphoes connected), this should force headphone mode ?

I'm very sorry - can't think of any other simple checks re the WiFi just now.
However still some hope with the headphone output - I can now see from your photo that you have used the uUSB to USB A Host adpater - the plug on this is internally wired with a short between pins 4 and 5 (0V and the Sense pin). That causes the device to go into Host mode - so it is expecting to see a USB Flash Drive or similar on the end - not headphones. You need a lead with a basic uUSB B (that's the shaped connector with black insert rather than this one which is rectangulat with a white insert).
When I mentioned the 'original connector' previously, I was referring to checking with the supplied earphone/mic cable....
Hope that helps resolve...
Best regards,
Kevin
