XDA 2 / TomTom / Serial Port (Im a newcomer to XDA)

Yesterday i purchased an XDA II, I have TomTom, and a Garmin GPS Map 76 S.
Garmin unit works perfectly on my Laptop with Navigator software.
While at the store purchasing the XDA2 i also purchased the Serial Cable, Part No AHTX2SCN.
The end of the serial cable and the GPS cable are both Male outputs, but i managed to gerry rig a cable to connect them together.
TomTom shows a few ports, infrared, BT on com6, Serial Cable on Com1 com9, com2, serial on usb.
When i try to use Com1, the port is not available.
Does anyone have any suggestions on how to fix this ( i cant see how to disable infrared) or any suggestions as to what GPS receiver to use instead of the garmin.
Thanks.

Go to settings/connections/beams, make sure beams is unchecked. Also you may need to add a null modem adaptor between the serial cable and the xda2 cable, or you can cross over the wires by desoldering , on the serial end swap over lines 2 and 3, in other words desolder 2 and 3, put 3 where 2 was and put 2 where 3 was.

Initially there was nowhere to untick "beams", now there is and it is unchecked, i never unchecked it, and can't explain why it was like this, the XDA has been acting strange though, locking up, being very slow etc.
I will look for a null modem adaptor, and report any success or lack of back here.

Apart from the "beam" issue, you must have a "proper" null modem adapter.
It should work.

It works
Finally i got the GPS to work with some parts from Maplins ( try Radio Shack outside of the UK)
Using the Serial Lead i described above, i purchased the following items from Maplin, the guys there were very helpful, letting me take the follwoing configuration outside to check if it worked.
I purchased the follwoing :-
Low profile 9W Male to Male Gender Changer part number JW57M. I needed 2 of those. (basically two small gender changers)
9 way Null F-F 2m part No VD76. (basically a null modem cable).
Connected them all up, and GPS now works. The resulting lead is a bit untidy / long, but for now i've just used plastic ties to tidy it up a little.
Total cost of the above parts was just short of £15.
Hope this helps someone.
www.maplin.co.uk for online ordering, or 0870 264 6000 so it says on the parts.

You could have got a very tiny male>male null modem adapter from us for $5.90, or a slightly bigger one from Expansys for £2.94 !

You can do this a lot cheaper.
Several possibilities:
- buy a plug for the Qtek @ http://www.gomadic.com/ipconplug38s.html and one for the Garmin GPS @ http://www.pfranc.com and a short piece of shielded wire. You just have to connect 2 wires (Tx from the Garmin to Rx from the Qtek), and this works very well.
- for those who find the connector of the Qtek to small: buy a regular serial cable, cut off the 9 pin connector and solder a Pfranc in place.
There are a lot more possibilities, like powering everything from one source (GPS and Qtek). And price is a lot lower than ready made stuff...

Blue Angel Hyperterminal and Telnetl Via Bottom Connector

Hi there
Part of my job envolves monitoring data from various sensors, this involves booting my laptop, pluging it in, cause the battery fecked, hookin to the sensor, 3 seconds to check the data then pack it all away again.
I think I`ve found a Hyperterminal for ppc called vxhpc, looks like it has the right functions.
I have opened a plug that I have that connects to the bottom plug, and I can see 22 pins, but I dont know which one does what.
I`m after com1 wiring I think, it will mostly be RS232 signals that I`m monitoring.
The options in the software are:
Serial cable on com1
CAM1
IR Port
Com2 Serial on usb
there are a few more.
I assume serial on com1 is the obvious choice, but you guys and gals will know better than me.
So the pin outs of the bottom connector, and if anyone knows of a better software, that would be fanastic.
The telnet part, I also have some telnet software called Mini Telnet, Many of the systems I work on control ship engines and thruster, If i could connect to the engine managment system network via the XDA2S, I could, In theory, control the ships movement, and monitor the system aswell.
Unfortunatly, due to saftey reasons, all networks on ships are hardwired.
Is it possible to connect from the bottom plug to a network hub ?????
If so, do you know how ?
Thanks for all your help
All the best
Nikki

just noticed, the Wallaby and Himalaya have the same wiring, does this mean, chances are the blue angel is the same again ? maybe ??

okay, i have been investigating a wee bit, my findings so far, this is about the telnet side of things, if I`mwrong anywhere, please correct me.
Taken from the wiki site
5 ANALOG GND
6 RS232_DCD
7 RS232_CTS
8 RS232_TXD
9 RS232_RTS
10 RS232_RXD
11 RS232_DTR
So, RJ-45 to DB9 pc comport
rj 45 side -------------------XDA2s Side
1 DCD------------------------6 DCD
2 DSR------------------------?? DSR, i dont see this one on the list, is it important ?
3 DTR-------------------------11 DTR
4 SigGnd----------------------5 SigGnd, Plenty of these
5 TXD-------------------------10 RXD ???
6 RXD-------------------------8 TXD???do i have these the right way around ?
7 CTS-------------------------7 CTS
8 RTS-------------------------9 RTS
So, does this look about right ? and how important is the DSR signal, I`m unsure of it puropse.
Like I said, if you see anything wrong, at all, please post
cheers

If using com 1 make sure you have beams switched off in settings/connections, also disable any external keyboard driver if present as this too will take com 1.

Is there a serial lead available ?

All the servers at work have com ports for a console connection, it would be handy if I could connect using a serial lead and a terminal service to them with my XDA
Is anything available yet ?
Thanks

Serial "lead"
You may try the german company lintech's (lintech.de) RS232 Bluetooth Mini Adapter S (part No. 1409/s). Sits like a dongle on the server side and allows for serial via BT, p. e. with typical terminal progs. Works a treat..

serial device connection to wizard?

I have an older software application (around Windows CE timeframe) running on the Wizard. It runs fine. The program is designed to take RS232 serial data from a comport and plot it on a map screen. Here's the issue: Older devices had cables that connected to serial (db9) connectors on one end and plugged into the phone on the other end. Any ideas on how to work this on a Wizard?

What ethernet speed depends on? (100m - 1000m)

Hi
I've bought a 'x96 x4 1000m' device recently which turned out to be a 100m one at last. I've opened a dispute for partial refund which I won, but I'm still not satisfied, need answers.
In short: What differences on the PCB shall I look for in general, if a device officially offers 100m and 1000m model variants?
Actually I did some investigation on this particular model and found this:
A test on an 1000m device. (The review is a possible proof that 1000m devices of this model do exist. I don't speak russian though and automatic translation is trash. If I put correctly together the review, the box is trash too, but that is a different story.)
A review on a 100m device.
Now the twist. (To me) both boards look identical! Both are equipped with this component. Unfortunately I'm not an electical engineer, so it is not a fact but only suspicious.
May 100m be a software limitation only? Would be justifiable from manufacturing point of view, but simply stupid from marketing perspective.

So I've learned today that an ethernet controller chip should be present on the PCB to provide gigabit ethernet. That piece of chip is missing, so having a 100m lan is not coincidence but actual hardware bottleneck.

i bought x96 x4 64GB ROM/LAN 1000, and when i tested the LAN it only has 100mbps, but i found out that it is not compatible with the network plug, that plug i plugged into wifi6 it broadcast with 5Ghz ac is 250mbps, my network broadcast is 400mbps if test with LAN 1000, if I want it to receive LAN 1000 then I have to replace the network end again, I take 1 gigabit LAN port on wifi 6 and plug it back into x96 x4's LAN port it gets 1000mbps. If you want to know if your box is LAN 1000 or not, you have to test plug the box into PC, 64/1000 with the codename in the introduction if it's X96_X4_Pro, then it's LAN 1000, and if its showcase name is X96_X4_Pro1 then is LAN 100

I've already sold the box to someone who didn't mind having 100m only. And yes, if I remember correctly it had a name X96_X4_Pro1.
Actually I've been testing it with a 10Gbps cable hanging from a gigabit port of a wifi6 router. The very same cable provides to this day gigabit connection to an older box of mine with actual gigabit port.
So yeah, everything is just correlating nicely. The naming convention of this particular box, the connection speed with a well performing cable, and of course the missing piece of hardware (gigabit controller chip).
