HEIDENHAIN SHB Data Interfaces for HEIDENHAIN - Manual (Page 34)

April 2010 5 – 35
5 Operating Modes of the Data Interfaces
5.1 Operating Modes on TNC 125, 131, 135, 145, 150, 151/155
One or several operating modes are available, depending on the control model.
ME:
For connection of the HEIDENHAIN magnetic tape unit MP 101/102 or other peripheral units.
Data format (7 data bits, 1 stop bit, even parity) and baud rate (2400) are adapted to the FE.
FE:
For connection of the HEIDENHAIN floppy-disk unit FE 401 or other peripheral units. Data
transfer is executed with a special protocol (blockwise transfer) to back up data. Data format
(7 data bits, 1 stop bit, even parity), baud rate (9600) and transfer protocol are adapted to the FE.
EXT:
For adaptation of data transfer in standard data format and for blockwise transfer to peripheral
units. The interface for data transfer is adapted via machine parameters; any baud rate can be
selected.
1) Selection via MOD
