6.1.2 Description of the machine parameters

Machine parameters - general information

Data format

As of TNC 151 B/Q the data format can be set in the machine parameter MP 222.

Example:

For "Blockwise transfer" with the HEIDEHAIN data transfer software in the EXT mode, the data

format must be as follows:

7 data bits, 1 stop bit, even parity, software handshake

In the "FE/ME" mode, the data format in MP 222 is not active; in this case the format is always

set to 7 data bits, 1 stop bit, even parity and software handshake.
