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. If Honor DSR is Off, data received on pin 3 of serial interface is
seen as valid data. If Honor DSR is set On, only data received while the
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.
Set Honor DSR On to prevent any stray characters from printing.
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 see NETWORK MENU
on the display. Press Select. 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.
