Hi,
I would like to connect the SerAccel v3 to a CP2103 USB-Serial converter, but I can't get it working and don't fully understand how it can work.
The SerAccel v3 is designed to talk directly with the RS-232 port on a PC, which works on the RS-232 voltage levels (ie +12V for 0, and -12V for 1) ,right? However, the CP2103 is expecting TTL levels isn't it? (ie +5V for 1, and 0V for 0).
So, how do you connect them together?
Anyway, this is what i've tried so far:
I currently have it connected like this:
I plug in the CP2103, load the drivers and open the comm port in hyperterminal. I set the baud rate to 115200 and all I get is corrupted data :S
While it's all still plugged in, if I connect the TX terminal on the SerAccel to a real comm port on the PC, the data is fine.
Any ideas??
Cheers,
Steve
