14. RS-232-C-/V.24 Data Interface
14.1 Operating Modes ME FE EXT
For data transfer the TNC 306/360 can be switched to the following 3 operating modes:
ME
For connection of the HEIDENHAIN Magnetic Tape Unit ME 101/102 or
other peripheral units. Data format adapted to the ME: 7 data bits, 1 stop
bit, even parity, Baud rate 2400.
FE
For connection of the HEIDENHAIN Floppy Disk Unit FE 401/401B or other
peripheral units. Data are transferred with a special protocol (blockwise transfer)
for data security. Data format adapated to the FE: 7 data bits, 1 stop bit, even
parity, Baud rate 9600 and transfer protocol.
EXT
To adapt the transfer of data to external peripheral units in standard data format
and for blockwise transfer. The interface for data transfer is adapted via machine
parameters; any Baud rate may be selected.
Peripheral units for the EXT operating mode are:
- punched tapes and punched-tape readers
- mass storage media or programming stations for "Blockwise Transfer"
- programming stations and personal computers for external programming
*
The Baud rate set at the TNC must always match that of the peripheral unit.
Possible Baud rates: 110 - 38 400
