NPort 6000 Series User’s Manual Configuring Serial Port Operation Modes
7-30
Try next type on authentication denied (default=Disable): The field enables or disables the
system to try next type on first authentication denied.
Map keys <CR-LF> (default=CR-LF): This specifies how the ENTER key is mapped from the
Ethernet port through the serial port.
Option Description
<CR-LF>
carriage return + line feed (i.e., the cursor will jump to the next line,
and return to the first character of the line)
<CR>
carriage return (i.e., the cursor will return to the first character of
the line)
<LF>
line feed (i.e., the cursor will jump to the next line, but not move
horizontally)
Printer Applications
RAW PRN Mode
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for
a response to “keep alive” packets before closing the TCP connection. The NPort 6000 checks
connection status by sending periodic “keep alive” packets. If the remote host does not respond to
the packet within the time specified in this field, the NPort 6000 will force the existing TCP
connection to close. For socket and device control modes, the NPort 6000 will listen for another
TCP connection from another host after closing the connection. If TCP alive check time is set to 0,
the TCP connection will remain open even if there is no response to the “keep alive” packets.
Group (default=Group 01): This field groups printers attached to different ports. When printing
requests are sent a group of printers, all printers in that group will share the printing load. For
example, setting the NPort 6000’s serial ports 1, 3, and 6 to Group 01 will allow the printers
attached to these three ports to act essentially as one printer.
TCP port number: This field is automatically filled in by the NPort 6000 and cannot be set by
the user. The host uses this value to determine the Group to which the printer attached to this serial
port belongs. Groups 01 to 06 are mapped to ports 2048 to 2063 respectively.
