Serial Menu
The Serial Menu is only displayed when a serial interface exists on
the printer model as a standard feature or as an option. Serial
interface is a standard feature on the Optra S 1855.
The following menu items appear when you selectSERIAL
MENU.The second level of menus for Serial Menu are:
STANDARD SERIAL
The Standard Serial menu item is displayed for printer
models with serial interface as a standard feature or as an
option.
SERIAL OPTION 1
SERIAL OPTION 2
SERIAL OPTION 3
Serial Option 1 to Serial Option 3 are displayed if a Tri-Port card is
installed in connectors 1 to 3 on the printer system board. The
serial functions for each card are displayed as values in the Serial
Option menu for that card.
Menu items set the configuration of the serial interface connection.
The items are listed in the order that they appear in the menu.

PCL SmartSwitch Off
On*
SettingPCL SmartSwitch Onlets the printer examine the data on the serial
interface connection and selects PCL emulation if the data indicates that is
the printer language.
If bothPCL SmartSwitchandPS SmartSwitchare setOff,theprinter
uses the language specified in the Printer Language menu as the default. If
only one SmartSwitch setting is setOff, the printer uses the language that
has its SmartSwitch settingOnas the default.
PS SmartSwitch Off
On*
SettingPS SmartSwitch Onlets the printer examine the data on the serial
interface connection and selects PostScript Level 2 emulation if the data
indicates that is the printer language.
If bothPCL SmartswitchandPS Smartswitchare setOff, the printer uses
the language specified in the Printer Language menu as the default. If only
one SmartSwitch setting is setOff, the printer uses the language that has its
SmartSwitch setting setOnas the default.
NPA Mode On
Off
Auto*
NPA is a mode of bidirectional communication that follows theNetwork
Printing Alliance Protocol, A Printer/Host Control Specification Developed by the
NPA. This mode requires the printer to perform special processing of the
data. The NPA Mode menu item under SERIAL MENU only applies to the
serial interface connection.
IfNPA Modeis setOn, the data received must be in NPA format. If not, it is
rejected as bad data. IfNPA Modeis setOff, the printer does not perform
any NPA processing. IfNPA Modeis set toAuto, the printer examines the
data to determine the format and then processes it in either format.
Changing the NPA Mode setting automatically resets the printer.

Serial Buffer Disabled
Auto*
3K to maximum size allowed
Your printer has a variable buffer size that can be changed from the
operator panel. You can configure the size of the input port buffers to meet
your system needs. The maximum size available for modification depends
on the amount of memory in your printer, the size of the other link buffers,
and if theResource Savesetting isOnorOff. To maximize the range for
the Serial Buffer size, you can disable or reduce the size of the parallel,
network, Infrared, Fax, and LocalTalk buffers. The Auto setting indicates
the printer selects the buffer size based on the total memory available.
Changing the Serial Buffer setting automatically resets the printer.
Job Buffering Off*
On
TheJob Bufferingmenu item does not display if the formatted hard disk
is defective, is Read/Write or Write protected, or if the Job Buffer Size is set
to Disabled.61 Defective Diskdisplays during printer power on. See61
Defective Diskon page 189 for more information. Also, see Job Buffer Size
on page 93.
Job buffering lets you delay processing of a print job. The job is temporarily
stored on an optional hard disk before being printed. This usually frees the
host computer during the actual printing of a print job.
IfJob Bufferingis setOn, print jobs are buffered to the hard disk. IfJob
Bufferingis setOff,theprintjobsarenotbuffered.
Changing the Job Buffering setting automatically resets the printer.
RS-232/RS-422 RS-232*
RS-422
Choose the serial communication configuration for your printer. If RS-422
is selected, Serial Protocol is automatically set to XON/XOFF.
RS-422 Polarity Normal*
Reverse
If you select RS-422 for the serial communication configuration, you can
then select Normal or Reverse polarity.

hardware handshaking, software handshaking, and combined hardware
and software handshaking as indicated in the preceding list.
Refer to theTechnical Referencefor more information on the serial interface.
Robust XON Off*

logical 1’s per byte. The port transmits XOFF and XON with even
parity. If the port detects a parity error, the port sends an
inverted question mark to the printer instead of the character
sent by the host system.
Odd The port expects to receive data frames with an odd number of
logical 1’s per byte. The printer transmits XOFF and XON with
odd parity. If the printer detects a parity error, the port sends
X5F to the printer instead of the character sent by the host
system.
None The port expects no parity bit when it receives data. The port
transmits XON and XOFF without parity bits.
Ignore The port expects a parity bit when the port receives a data frame.
The port ignores the parity bit. The port uses even parity when it
transmits XON and XOFF.

Three option cards can be installed in the Optra S 2455, two option
cards can be installed in the Optra S 1855, and one option card can
be installed in the Optra S 1625 and Optra S 1255.
If Network Option cards are installed, you seeNETWORK MENU
on the display. PressSelect. If the card is installed in connector 1
on the printer system board, the functions for that card are
displayed as a value in the Network Option 1 menu. If the card is
installed in connector 2 on the printer system board, the functions
for that card are displayed as a value in the Network Option 2
menu. If the card is installed in connector 3 on the printer system
board, the functions for that card are displayed as a value in the
Network Option 3 menu. Functions for the three networks operate
independently of each other.
The following menu items are available for the Network Option 1,
Network Option 2 and Network Option 3 menus. Change the
settings for this menu item to set up network communications.
Honor DSR Off*
On
DSR is one of the handshaking signals for most serial interface cables. The
Honor DSR setting determines whether the printer accepts the incoming
print data. IfHonor DSRisOff, data received on pin 3 of serial interface is
seen as valid data. IfHonor DSRis setOn,onlydatareceivedwhilethe
DSR signal is in high condition is treated as valid data.
The serial interface uses DSR to determine if data arriving on pin 3 is sent
by the host computer or created by electrical noise in the serial cable. This
electrical noise can cause receive errors and create corrupted data that
causes stray characters to print.
SetHonor DSR Onto prevent any stray characters from printing.
