Connecting the Cash Drawer

Cash Drawer Requirements

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 ohms or more or the input current
must be 1A or less.
• Be sure to use the 24V power output on drawer kick connector pin 4 for driving the equipment.

connect both the optional external buzzer and the cash drawer to the printer at the same time
by using a branched connector.

set to "enable". When using the cash drawer, be sure to set it to "disable" using the Epson TM-
