4–13 Printer Interfaces
RS-232 Serial Interface Configuration
The printer is configured at the factory to match the interface specified by the
customer. You can also configure the printer via its control panel. You can
verify or change the following interface parameters as necessary to meet
specific application requirements:
•
Data Protocol of hardware (DTR, Reverse Channel, or RTS), or
X-ON/X-OFF, ACK/NAK or ETX/ACK
•
Data Rate (BAUD rate selected from the control panel)
•
Data Word Length (7 or 8 Bits)
•
Stop Bits (1 or 2 Bits)
•
Parity (Odd, Even, or None)
•
Bit 8 Function (Font Select, PI Line, or Ignore)
•
Data Terminal Ready logic
•
Request to Send logic
•
Reverse Channel logic
These parameters are under the Host Interface/Serial RS-232 submenu and
are described in Chapter 3, Configuring the Printer.
NOTE: Do not select the PI line setting of the Bit 8 Function parameter
unless the host computer uses bit 8 for paper control. Otherwise,
rapid vertical paper movement (“slewing”) may occur.
Some applications programs require a unique configuration. If the printer is
not working properly in the configuration you selected, contact your
authorized service representative.
