specifications of the serial VT-100 device to ensure fault-free communication
between it and the CATPro2 VT100.
The following settings are available:
• Baud rate
• Character size (bits) (if you enter a value less than 8 you can no
longer enter any special characters)
• Parity
• Stop bits
In these four scroll-down menus, select the values that suit your application.
Note: If you set up the Baud rate higher than 38400, we recommend the
activation of one the two options in the panel „Flow control“.
In the "Flow control" panel you can configure the data stream of the RS232
interface.
The following settings are available:
• Hardware (RTS/CTS)
• Software (XON/XOFF)
As soon as you have selected an option, the "Maximum buffer fill" field is
activated. In this field, set the level to which the internal buffer of the CATPro2
VT100 may be filled before the counterpart receives a signal that the data
stream should be interrupted until the buffer is again ready to receive data. This
prevents a Buffer Overflow.
If you do not activate any of these options, it will be possible for a Buffer
Overflow to occur. 'Information on whether or not there is a Buffer Overflow is
provided in the bottom right field of the terminal window. This message
disappears when there is sufficient free memory in the buffer for the incoming
data stream.
In the "Interface" panel you can define the operating mode of the CATPro2
VT100. This operating mode depends on which serial connection cable is in
use.
