RS-422 Polarity
= Normal*
= Reverse
Select Reverse polarity to swap the polarity (the definition of
one and zero).
This setting is only available if the serial communication config-
uration is set to RS-422. Select Serial Menu, SERIAL
OPTION 1, RS-232/RS-422, and RS-422.
Serial Protocol
= DTR* (hardware handshaking)
= DTR/DSR (hardware handshaking)
= XON/XOFF (software handshaking)
= XON/XOFF/DTR (combined handshaking)
= XONXOFF/DTRDSR (combined handshaking)
The printer supports hardware handshaking, software
handshaking, and combined hardware and software
handshaking as indicated in the list of values for this menu item.
Refer to the
Technical Reference
for more information about the
serial interface.
Robust XON
= Off*
= On
Robust XON only applies to the serial port if Serial Protocol is
set to XON/XOFF. When Robust XON is set to On, the printer
sends a continuous stream of XONs to the host computer to
indicate that the serial port is ready to receive more data.
