Thanks for your speed actually.
In that case, I can install a PCMCIA card with two USB 2 ports on my notebook. And I can use USB-RS232 converters. Then will the two units (TC-08 serial) work together, if I also make a proper external power supply for the units? (By the way, my std. power supply has +15V, GND, -15V terminals. Is it okey or should the voltages be lower?)
What about breaking a new speed record (on a Saturday)!
Thank you in advance.
