RTS Function
Values: On/Offline&Buf (default), True, False or On/Offline.
This parameter must be set to match your host computer.
The RTS Function parameter is part of hardware flow control. This
parameter determines when the printer generates the Request to
Send (RTS) signal to the host computer. RTS is a status signal that
the printer sends to the host to indicate whether or not the printer is
ready to receive data.
• The True parameter setting causes the printer to continuously
assert the RTS signal.
• The False setting causes the printer to never assert the RTS
signal.
• The On/Offline&Buf setting (the default setting) causes the
printer to assert the RTS signal only when the printer is online
and its internal serial buffer is not full.
• The On/Offline setting causes the printer to assert the RTS
signal whenever either the printer is offline or its internal serial
buffer is full.
DTR Polarity
Values: Normal (default) or Inverted.
This parameter must be set to match the DTR signal polarity of your
host computer.
This parameter enables the DTR signal to invert if required for a
particular installation.
RTS Polarity
Values: Normal (default) or Inverted.
This parameter must be set to match the RTS signal polarity of your
host computer.
This parameter enables the RTS signal to invert if required for a
particular installation.
