UV6000LP DADetector RS232 protocol

[wally]

Hi

I need to interface the Spectra Systems UV6000LP detector using its RS232 port. In standard docs/manual i cannot find any specification except the baudrate, stopbit and parity settings.
I also do not have a working software to drive this device so i might "sniff" or listen to the communication.
Any kind of information is highly welcome, thank you!

9 times out of ten, 9600 baud, 8 data bits, no parity bit, and 1 stop bit (9600-8-N-1) is the way to go. You could use Hyperterminal (included with every version of windows since, well, forever) to open a connection to the com port you're using. Start with the settings above and try throwing random characters at it until you get a response. If there's some sort of serial port diagnostic test in the firmware of the detector, you could initiate it while "listening" with Hyperterminal. Most serial devices I've used have some sort of diagnostic that involves shorting the send and receive pins of the serial port and letting the device talk to itself. If you have a Hyperterminal session open and a com port connected to the device instead of shorting the pins, you may be able to find the right settings by adjusting them one at a time, and running that diagnostic till you receive some characters that make sense. If that doesn't work, I could dig out the manual for my old UV2000. I don't know if it even has a serial port, but if it does, they might use the same specs.
