Connecting the Cash Drawer If the optional external buzzer is used, you cannot use a cash drawer. Connecting the Drawer Kick Cable WARNING • Specifications of drawers differ depending on makers or models. When you use a drawer other than specified, make sure its specification meets the following conditions. Otherwise, devices may be damaged. ∗ The load, such as a drawer kick solenoid, must be connected between pins 4 and 2 or pins 4 and 5 of the drawer kick connector. ∗ When the drawer open/close signal is used, a switch must be provided between drawer kick connector pins 3 and 6. ∗ The resistance of the load, such as a drawer kick solenoid, must be 24 Ω or more or the input current must be 1A or less. ∗ Be sure to use the 24V power output on connector pin 4 for driving the equipment. • Use a shield cable for the drawer connector cable. • Two driver transistors cannot be energized simultaneously. • Leave intervals longer than 4 times the drawer driving pulse when sending it continuously. • Be sure to use the printer power supply (connector pin 4) for the drawer power source. • Do not insert a telephone line into the drawer kick connector. Doing so may damage the telephone line or printer. • For specifications with a built-in buzzer, use a cash drawer operated by pin 2 of a drawer kick connector. When using a cash drawer operated by pin 5, you need to make printer settings. For details, see "Setting the Built-in Buzzer (for Model with a Built-in Buzzer)" on page 42. Connect the connector of the drawer kick cable to the printer. Drawer kick connector 40
