How to send 7 bit ascii char ? All the time, I receive answer that message ack, but invalid caracter in data feild.

Baud rate is 1200, E , 7 , 1

A lookup table would be something you could do.

The NXC-COM2 can be configured for 7 data bits, but NI-X100 controllers can't. One approach would be to configure your NetLinx port for 8N1 and ignore the high bit of each byte received (it will be the parity bit). What's the device? What are you trying to control it from?

Once you get the port configured correctly, you just send strings normally from your program, no lookup table required.
