Serial Communication with RS-232 to USB

Hi,

I've been communicating with my DT80 using a little python code, configuring a serial port and sending string commands to the datataker. I've been successful using the USB cord that came with the machine, however when I use an RS-232 to usb cord, the DT80 doesn't seem to receive (or send) any information.

How can I set up the DT80 for serial communication with an RS-232?

Thanks!

Hi SnTern,

Default setting for serial port on the left (we call it Host Port) is COMMAND. As a default this port is used to send syntax to DT.
If you want to use this port to write/ read serial string, please change its function to SERIAL (PROFILE HOST_PORT FUNCTION=SERIAL).

You may also need to change host modem setting to remove a standard AT header for string out from DT and modem detection.
PROFILE HOST_MODEM INIT=""
PROFILE HOST_MODEM DETECTION=NEVER

Best regards,
Rudy Gunawan
