Technical specifications for the ASCII driver
The table below shows the technical specifications for the ASCII driver.
Table A- 6 Technical specifications for the ASCII driver
ASCII driver
Max. message frame
length
1024 bytes
Parameter The following can be configured:
Transmission rate: 2400, 4800, 9600 bps
Character frame: 10 or 11 bits
Character delay time: 4 ms to 65,535 ms in 1 ms increments
Flow control: none, XON/XOFF, RTS/CTS; automat. control of V.24 signals
XON/XOFF characters (with "flow control" = "XON/XOFF" only)
Wait for XON after XOFF (wait time for CTS = ON): 20 ms to 65530 ms in 10-ms
increments
Time to RTS OFF: 20 ms to 65530 ms in 10-ms increments (only for "automat. control of
V.24 signals")
Data output wait time: 20 ms to 65530 ms in 10-ms increments (only for "automat. control
of V.24 signals")
Delete CP receive buffer on startup: Yes/no
Number of message frames to be buffered: 1 to 250
Prevent overwriting: yes/no (only when "buffered receive message frames" = "1")
Indicator for end of receive message frame:
After character delay time expires
On receipt of end-of-text character(s)
On receipt of a fixed number of characters
ASCII driver with end-of-message frame detection at end of character delay time
Parameter No other parameter assignments need to be made. The end of a message frame is detected
when the programmed character delay time elapses.
ASCII driver with end-of-message frame detection using configurable end characters
Parameter The following can be assigned:
Number of end-of-text characters: 1 or 2
Hex code for first/second end-of-text character
ASCII driver with end-of-message frame detection using configured message frame length
Parameter The following can be assigned:
Message frame length: 1 to 1024 bytes
