External data transfer
Integrating TNC interfaces EXT1 (5020.0) and EXT2 (5020.1) to an external
device:
MP5020.x
7 data bits (ASCII code, 8th bit = parity):
+0
8 data bits (ASCII code, 9th bit = parity):

Transmission stop through RTS inactive:
+0
Transmission stop through DC3 active:

Transmission stop through DC3 inactive:
+0
Character parity even:
+0

Example:
Use the following setting to adjust the TNC interface EXT2 (MP 5020.1)
to an external non-HEIDENHAIN device:
8 data bits, any BCC, transmission stop through DC3, even character
parity, character parity desired, 2 stop bits
Input value: 1+0+8+0+32+64 = 105 (entry value for MP 5020.1)
Interface type for EXT1 (5030.0) and EXT2 (5030.1):
MP5030.x
Standard transmission:
0
Interface for blockwise transfer:
1
Define data transfer through EXT1 (xxxx.0) and EXT2 (xxxx.1):

Data input (1st character) H
MP5203.x
Data input (2nd character) E
MP5204.x
Data output (1st character) H
MP5205.x
Data output (2nd character) A
MP5206.x
Start of heading (SOH)
MP5207.x
End of transmission block (ETB)
