Printronix L5035 user manual Serial Parameters RS-232 And RS-422 Stop Bits, Parity, DTR Function

Serial Parameters (RS-232 And RS-422)

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.
