[markbraz]

Hi All
Trying to connect my new Nanocom to laptop without serial port. I am trying to use a cable adapter from ebay and although the driver seems to have installed and nanocom.exe tries to connect on com3 it wont download files from Nanocom. Anyone with experience of this can help please?

try plugging your RS232 lead in to your nanocom and the other end in to your lap top restart laptop see if that works let me know

Thanks for responding, tried that still no joy. Nanocom.exe does know 'something' is there as it sees it on com3, - all other ports it says no connection.
I'm wondering if the cable is any good?

You may need to amend the comm settings for the COM port. Try setting the port parameters to 9600 (baud rate), 8 (data bits), N (No Parity), 1 (Stop bit). Its probably defaulted to 115200bps which in all likelihood will be too quick for the nanocom.

Hi, i've checked the port setings and they are as suggested above, still no connection. Interestingly i removed nanocom.exe and reinstalled and on all comm settings but com3 it says unable to connect - even when usb is not plugged in. I'm sure its something to do with the serial/usb driver not showing correct com# but can't figure it out.
Thanks for suggestions.

if you go in to port settings in device manager click on ports click your device usb lead click on advanced and see what it says your port setting is change to 5 and see what that does because if youve got other stuff connected printer etc it will take ports 1,2,3,4, first if you no what i mean

dazzerboy, thanks for help. All ports except 2 & 9 are 'in use' so i changed it to 9 in advanced and in nanocom.exe and now i get 'communication error' and 'no file in nanocom' instead of the progress bar just scrolling the orange boxes! I reckon this is progress anyway! Will try to see what is using the comm ports and temp disable them i think, see where that gets me.
Cheers

I doubt very much that all ports except 2 & 9 are in use. I would suggest changing the com2 port number to say com10. Then find the USB com port and change that to com2 and set the comm settings as described before.

Is your USB-Serial lead a USB-RS232 cable? There are many versions of RS232, not all of them designed for PC comms. Did your USB-Serial drivers install correctly?

[markbraz]

Yes it is a usb - rs232 cable, i reckon this may be faulty. Will get a new one to try. The Nanocom works fine via the supplied serial cable to my sons pc but as he spends his life playing games on that i can't anylise my Td5 files:(. Will report what happens.

Looks like it was wrong type of adapter. Third one tried worked fine. Of course poss that first two were faulty.

Glad you got it sorted.. for future reference I do a lot of work with RS232 / 422.. And these usb adapters are becoming more common as computers are rarely fitted with proper com ports these days.

I have found that stuff from maplins seems to work quite well, purchased one the other day and it worked straight out of the box :)
