Tom Tom & IPAQ 1910

Neverlost · Posted: Sun Sep 14, 2003 8:04 am Post subject: Tom Tom & IPAQ 1910

Anyone managed to locate a cable to connect a Leadtek 9532 to an IPAQ 1910? If so are there any software issues in running TomTom2 on the Ipaq 1910?

There is not and will never be any such cable as the 1910 has no serial port connectivity. It's a real shame as the 1910 is a lovely unit but GPS is sadly not going to happen for 1910 owners

To add to what Darren said - the only possible option for GPS on a 1910 seems to be someone coming up with a way of interfacing a GPS to the infrared port.

There's seemingly only two options for I/O on a 1910. There's a conventional IrDA port, also the USB port - but the USB port is client only (so no chance of hooking up a USB GPS to it). There are a couple of Pocket PCs with USB host capabilities - but nothing from HP.

It's possible someone will come up with a gadget that allows you to link an ordinary serial device to the 1910's infrared port - but the potential market for such a gadget is quite small - probably too small to recoup development costs.

The 1910 is, so far as I remember, the only Pocket PC on the market that lacks both a serial port and a CompactFlash slot, and it's only really 1910 owners who are going to want such a gadget. You'd have all the hassle of keeping the ports lined up too - realistically you'd need a special cradle.

The SD slot is apparently for memory only on the 1910. There's certainly no signs of any SDIO drivers from HP and it looks as if the 1910 hardware is not SDIO capable (the 3800 series certainly is *not* SDIO capable, the 3900 series and 5400 series are SDIO capable). In any case, a SD linked GPS would leave you with insufficient memory for navigation applications.

Maybe someone will come out with a combo memory and Bluetooth SD card (just as combo memory and Wi-Fi cards are being talked about) - but that's still no good if your Pocket PC doesn't support SDIO.

The 1910 simply doesn't have a serial port, nor does it have the ability to add ordinary iPAQ expansion packs (so no chance of adding a CompactFlash slot that way).

Apart from the I/O problems, the 1910 has less usable memory than many modern Pocket PCs, and it has less processing power than many alternatives (with it's 200MHz PXA250 XScale chip).

I am sure Darren's conclusion is right - realistically the 1910 is useless for GPS. It's a great PDA - but not so good for all the more advanced things Pocket PC can do because of it's limited expandability.

Hi Cable found at Widget. Thanks for the response

Do you have any further details, TomTom still do not list the 1910 as a supported model and all the info I have states it cannot interface with any current GPS due to it's lack of a serial port?

Neverlost, Duncan's contacted Widget and the cable doesn't work with the 1910, they were originally informed it would but they've received complaints back that it doesn't, so this will be revoked shortly. Unfortunately the 1910 was created as a cheap entry level PDA which doesn't have the full features that other PDA's have like the ability to have virtual serial ports.

Sorry!

I will be surprised they have.

Someone must be ill informed or did not know what he is talking.

I do not think it is possible, up to now.

We have many people asking for GPS connection solution for Ipaq 1910 AND Toshiba e310, this is always our answer:

If you want to use GPS with a PPC, you have to change to another PPC!

IR is possible but not practical or economically viable.

BT is possible for e310, but is even more expensive so it is still better to get another PPC instead.

(the 1910 has been reversed) The HP/Compaq WEB site states that the H1910 model does not support serial connectivity

The iPAQ Developer's site is clear - the serial port pins are 'reserved' on the 1910, and the connector has been turned round to signify it is different.

The wiring of the USB and power pins on the 1910 is identical to the 3800, 3900 and 5400 series.

Personally, I think leaving out the serial port is a very strange omission, as it removes the options of keyboards and the like. However, it will reduce the cost, board space occupied and power consumption of the device.

The TTL level to 'proper' serial level converter hardware needed for a proper serial port can be a particular drain on power - Dell have not built this in to the Axim X5, but they did build in the all important UART. On the X5, if you need the level convertor hardware, you have to provide it externally.

The iPAQ Developer's site also makes no mention of SDIO on the 1910. It is likely, as I put in my earlier post, that the hardware is not SDIO capable; if so, SDIO can't be implemented with new drivers.
