CHAPTER 10
SERIAL INTERFACE
INTRODUCTION
The optional serial BIP (Basic Interface Pack) RS-232C
delivers serial data from a host computer into the Citizen
120D+ printer.
The Citizen 120D + contains a set of switches inside the
interface cartridge that allows you to control the way the
printer behaves. These internal switches determine the
default condition for several of the 120D + 's features.
Changing the Interface Cartridge
The interface cartridge has been uniquely designed for two
purposes: for simple installation of the optional interface,
and for quickly changing the internal switches.
WARNING:
Never remove the interface cartridge when the power is on.
Doing so may damage the printer and/or your computer.
