Setting Serial Port
After setting parity, you are prompted for the RS-422 port.
USE 422 IN? N
The DL20 RS-422 port can transmit and receive data from other DL20
devices used as addressable masters or slave DL10 / DL50 displays.
•
If you want to use the port as an output, answer No. All data output at the
RS-232 port will also be transmitted at the RS-422 port. Set the port to
output if slave displays or addressable masters are being used.
•
If you want to use the port as an input, answer Yes. Data can then be
received at the RS-422 port just like the RS-232 port.
After selecting RS-422 port direction, you are prompted for a blank line
between messages.
PRINT BLANK LINE?
Answering No reduces the amount of paper used and answering Yes makes
the printout easier to read.
