Using RS232 with serial to USB converter

[Brian]

I tried to use the rs232 interface on a laptop with a usb to serial converter. The converter initialised at port 16 whereas the selection in the program is 1 to 4. The driver for the converter however allows seledtion of any unused port number, so I tried 1 and 2 as they were free. I recieved an error message from the program "Cannot open port '\\.\COM1'. Now the slashes in that string will probably be mangled by the script so to repeat it in text, Apostraphy slash slash dot slash com1 apostropy.
Any advice or experience in respect to resolving this would be greatly appreicated.

Well, I seem to have got rid of the error message. It mayhave just been removing and replacing teh usb to serival adapter. I will try to reporduce and document.

OK.
The USB to serial device just had to be removed and reinserted after the drivers were installed. The jigger is talking happily to the laptop now.
The next glitch I had was that the measurement was not appearing in the spreadsheet.
Arr harrr...! Using the topcon.theo file.... the instrument must be in slope distance measurement mode to match the design of the .theo file. If it is in horizontal distance mode, the measurement string will be recieved, but not transferred to the spreadsheet, which is good, because otherwise the slope correction would be applied twice and we may spend a long time chasing our tail.

Lots of traps for when one is in a hurry. Now I have to type in all the figures that could have been so easily transferred.
Next time.

Hi,

I have updated the software to accept connection to serial port 1 to 32.
Please, download and try with 16.
I am not sure this will work, as the code for serial com I have is somewhat outdated.
I have no time yet to update it, but might be able to do it this year.

Regards,
Emmanuel
