Altering Serial Interface Settings If you are using an optional serial interface, then you may have to alter the communications protocol of the printer or the computer in order to allow them to communicate properly. The protocol used by the printer is decided by one or two groups of DIP switches located on the serial interface board; the protocol used by the computer can probably be altered by a software command. It is essential that the printer and computer use compatible protocols. If you can, adjust the settings on the computer rather than the interface board as the interface is set up at the factory to give optimum performance under a wide range of conditions. If your dealer has installed the interface for you, he or she should also be able to set the G-6

Altering Serial Interface Settings
If you are using an optional serial interface, then you may have to
alter the communications protocol of the printer or the computer in
order to allow them to communicate properly. The protocol used by
the printer is decided by one or two groups of DIP switches located on
the serial interface board; the protocol used by the computer can
probably be altered by a software command. It is essential that the
printer and computer use compatible protocols.
If you can, adjust the settings on the computer rather than the inter-
face board as the interface is set up at the factory to give optimum
performance under a wide range of conditions. If your dealer has
installed the interface for you, he or she should also be able to set the
