External data transfer
Determining the control character for blockwise 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): +1
Block Check Character (BCC) any: +0
Block Check Character (BCC) control character not permitted: +2
Transmission stop through RTS active: +4
Transmission stop through RTS inactive: +0
Transmission stop through DC3 active: +8
Transmission stop through DC3 inactive: +0
Character parity even: +0
Character parity odd: +16
Character parity not desired: +0
Character parity desired: +32
1 1 /
2
stop bits: +0
2 stop bits: +64
1 stop bit: +128
1 stop bit: +192
RTS always active: +0
RTS only active if data transfer has been started: +256
Send EOT after ETX: +0
Do not send EOT after ETX: +512
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 for MP 5020.1: 1+0+8+0+32+64 = 105
