Serial Parameters (RS-232 And RS-422)
93
Stop Bits
Values: 1 (default) or 2.
This parameter must be set to match your host computer.
Stop bits signal the end of a transferred serial data word.
Parity
Values: None (default), 0, 1, Even, or Odd.
This parameter must be set to match your host computer.
The host may send a parity bit with every data word. The parity bit
is used for error checking.
DTR Function
Values: On/Offline&Buf (default), True, False or On/Offline.
This parameter must be set to match your host computer.
The DTR Function parameter is part of hardware flow control. This
parameter determines when the printer generates the Data
Terminal Ready (DTR) signal to the host computer. DTR 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 DTR signal.
• The False setting causes the printer to never assert the DTR
signal.
• The On/Offline&Buf setting (the default setting) causes the
printer to assert the DTR 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 DTR
signal whenever either the printer is offline or its internal serial
buffer is full.
