Serial interface connection diagram
When this printer is connected to a host computer by the serial interface, there are two
connection methods; stand alone connection and pass-through connection.
Stand alone connection
This printer is connected to the host computer directly via the serial port. When a customer
display (DM-D) is to be connected, connect it to the host computer via the serial port or USB
port.
 The printer uses a modular connector specifically designed for the cash drawer. Do not
connect the connector to a telephone line.
 For USB interface models, do not turn on the printer before installing the printer driver.
 For Ethernet interface models, do not connect a telephone line or DK cable to the
Ethernet connector.
