13.14.2 Setting V24 in the program manager
V24 setting Meaning
Protocol The following protocols are supported for transfer via the V24 interface:
 RTS/CTS (default setting)
 Xon/Xoff
Transfer It is also possible to use a secure protocol for data transfer (ZMODEM
protocol).
 Normal (default setting)
 secure
For the selected interface, secure data transfer is set in conjunction
with handshake RTS/CTS.
Baud rate Transfer rate: Transfer rates of up to 115 kbaud can be selected. The
baud rate that can be used depends on the connected device, the
cable length and the general electrical conditions.
 110
 ....
 19200 (default)
 ...
 115200
Archive format
 Punched tape format (default setting)
 Binary format (PC format)
V24 settings (details)
Interface
 COM1
Parity Parity bits are used for error detection: The parity bits are added to the
coded characters to make the number of positions set to "1" an uneven
number (uneven parity) or to an even number (even parity).
 None (default setting)
 Odd
 Even
Stop bits Number of stop bits for asynchronous data transfer.
 1 (default)
 2
Data bits Number of data bits for asynchronous data transfer.
 5 bits
 ...
 -8 bits (default setting)
XON (hex) Only for punched tape format
XOFF (hex) Only for punched tape format
