CNC / DNC Settings for Heidenhain TNC2500 (B/C)

Parameter Value Comments  
 
Baud Rate
TNC External Interface is capable of a number of different baud rates. For non-blockwise transfers we would suggest using 4800 or lower. But if you need to drip feed large complex programs then a higher speed such as 19200 will almost certainly be required and you should enable the Blockwise Protocol mentioned below.

Blockwise Protocol Enabled (0 = Disabled)

   

Data can be transferred in 'normal' mode if Blockwise is disabled. For example if your DNC software does not support it and/or transferring programs to/from CNC memory at lower baud rates.

But the TNC 2500 supports the Heidenhain Blockwise Protocol for reliable high speed drip feeding of programs that exceed the memory capacity of the machine. Blockwise Protocol is Enabled/Disabled via parameter 5030.

Use a DNC program such as RemoDNC that supports the Blockwise protocol.
See this page for setting up RemoDNC to drip feed large programs using the Heidenhain Blockwise Protocol
