EP-125KLIC Instruction Manual
Installation
1. Electrical
Power to the cash drawer is supplied through a
small 12VDC 0.5 amp plug-in module similar to
those used by portable telephone equipment and
calculators. Use of this module removes a
possibility of electrical shock from the metal
drawer or components on the interface board
and protects any equipment connected to the
cash drawer from damage caused by accidental
contact with the 115VAC potential of wall power.
The female connector from the module plugs into
the jack at the rear center of the cash drawer.
Important Note:
When changing the settings of the switches on
the interface board, the power connector must
be removed. Switch settings are only read by the
interface at power-up. New settings will not be
effective until power is removed and reapplied.
2. Configuring the Interface Board
The KLIC Universal Interface board supports all
three commonly used interface schemes for
communication to cash drawers. Selection of a
particular scheme is accomplished by setting four
banks of DIP (Dual In-line Package) switches on
the interface board located inside the cash
drawer on its rear panel. Access to the interface
board and the DIP switches is gained by
removing the plate at the rear of the cash
drawer.
Important Note:
Factory settings for the interface boards are
Dead End Serial mode operating at 1200 baud
using a drawer open signal of CONTROL G. If this
configuration meets your needs, no switch
settings need be changed. Charts showing
switch settings use “0” to indicate open/off and
“1” to indicate closed/on.
KLIC Switch Layout
To properly set the switches, you must know
which interface scheme you will be using. This
will be determined by the equipment available
on your computer or terminal, and any software
you are using with the cash drawer. The three
interface schemes are:
Serial – communication to the cash drawer is via
RS232 standard serial communication port
Parallel – communication to the cash drawer is
via parallel communication port
Pulse – drawer open command is supplied via a
voltage change from <2.5VDC to >3.5VDC.
Please skip to the heading that describes the
communication scheme you will be using.
Serial
Serial communication with the cash drawer
involves sending a unique drawer opening
character at a specific rate called the BAUD
rate. Any one of the standard ASCII character
codes may be used as a drawer opening
character as determined by preference or the
software being used.
CONTROL G (ASCII 7) is often used because it is
also the BEL character and many terminals emit a
short beep as the drawer opens. You may also
require an “ESC” prefix to the drawer opening by
setting switch 8 of bank 1 to on. This requires
that the “ESC” character immediately precede
your drawer opening character to be recognized
by the drawer.
Any of seven standard BAUD rates may be used.
Speed is not usually an important factor when
communicating with a cash drawer. So the
selection may be based on preference,
requirements of the software used, or
requirements of other equipment such as a
printer used in conjunction with the drawer.
Factory settings are for 1200 BAUD.
The third consideration for serial communication
is whether the cash drawer will be used in Dead
End mode or in Parasite mode. Using Dead End
mode means that the cash drawer is the only
device connected to the serial port. If you will
be using a printer, multiple cash drawers, or other
devices connected to the same serial port, use
the Parasite mode. * NOTE: When a cash drawer
is the last device in the chain it must be set in
Dead End mode.
Armed with the three pieces of information:
opening character, BAUD rate, and mode, you

are ready to set the switches for serial
communication.
Serial Dead-End – No other device connected to
this serial port. Use the KLIC layout diagram to
locate switch banks.

Parallel
Parallel communication with the cash drawer
involves sending a unique drawer opening
character. Any one of the standard ASCII
character codes may be used as a drawer
opening character as determined by preference
or the software being used. A favorite is the
CONTROL G (ASCII 7). CONTROL G is often used
because it is also the bell character and many
terminals emit a short beep as the drawer opens.
You may also require an “ESC” prefix to the
drawer opening by setting switch 8 of bank #1 to
on. This requires that the “ESC” character
immediately precede your drawer opening
character to be recognized by the drawer.
The other consideration for parallel
communication is whether the cash drawer will
be used in Dead End mode or in Parasite mode.
Using Dead End mode means that the cash
drawer is the only device connected to the
parallel port. If you will be using a printer,
multiple cash drawers, or other devices
connected to the same parallel port, use the
Parasite mode. * NOTE: When a cash drawer is
the last device in the chain, it must be set in
Dead End mode.
Armed with these two pieces of information –
opening character and mode, you are ready to
set the switches for parallel communication.
Parallel Dead-End – No other device used on this
port. Use KLIC layout diagram to locate switch
banks.

Pulse (Serial Mode)
Pulse communication with the cash drawer
involves sending a positive going pulse signal
from the computer on pin 2 (Transmit Data (TXD)).
The signal should be normally low (less then 2.5
volts) and should switch momentarily high to
greater than 3.5 volts to open the drawer.
Pulse Mode – No other device used on this port.

3. Cabling
The host computer, terminal, or point of sale
device is connected to the cash drawer through
a standard RS232 cable, the same as those
commonly used to connect serial printers. Two
DB-25 connectors are provided on the rear panel
of the cash drawer – one male and one female.
Either connector may be used to communicate
with the host device and the other may be used
to optionally connect a printer or additional
drawers in daisy chain fashion.
Important Note:
The DB-9 connector is becoming increasingly
popular as a replacement to the DB-25 connector
for serial port applications. If you point of sale
device uses the DB-9 connector for serial port
output, it may be necessary to obtain an adapter
to the DB-25 form. These can be purchased from
M-S CASH DRAWER, your computer store, or an
electronics parts house such as RADIO SHACK.
See Appendix A for differences in pin-out.
4. Testing
A simple operational check of the KLIC interface
can be done in pulse mode. Set the switch banks
for pulse mode and apply a signal of 5VDC to
12VDC momentarily between pin 2 (positive) to
pin 7 (negative) of the interface cable. The
voltage source may be from the computer buss or
simply a small battery. This check will test the
KLIC’s computer, power circuitry, solenoid driver,
as well as the drawer circuitry. (Make sure the
12VDC plug-in adapter is connected and
powered.)
Important Note:
Be sure to close the drawer when performing
tests. The KLIC interface is smart enough not to
energize the solenoid if the drawer is already
open.
Serial Test Program
The following program is written in QBASIC for IBM
computers and compatibles. The program
provides all the commands necessary to set up
the serial port and send characters to the drawer
to test your drawer opening code.
