M-S Cash Drawer Corporation
KPC type interface instructions
Introduction
The M-S Cash Drawer KPC trigger board enables the cash drawer to be controlled
directly by the computer's parallel port. Each cash drawer is supplied with a necessary
Dead-End cable or 'Y' interface cable. Several drawers may be "Daisy Chained" for
multiple drawer operation.
Installation
1. Connect the DB25 MALE connector of the 'Y'-cable into the computer's
parallel port.
2. Connect a standard parallel printer cable into the DB25 FEMALE connector of
the 'Y' cable.
3. Connect the 12VDC negative tip AC adapter (supplied) to the receptacle at
the rear of the cash drawer.
4. Plug the 12VDC power supply into 115VAC outlet.
5. Set the 10 DIP switches on the cash drawer for the desired opening character
and mode: (The factory setting is for BEL code/single character).
Dipswitches 1-8
are set to the binary representation of the ASCII open code.
Dipswitch 9
is unused.
Dipswitch 10
is set OFF to cause drawer to open each time open code is sent. Setting
switch 10 ON sets the drawer to double character mode where two opening characters
must be sent (without any other intervening characters) to open the drawer.
Common opening codes are:
NUL - Switches 1-8 OFF
BEL - Switches 1-3 ON Switches 4-8 OFF
See the ASCII chart for other character settings.
Testing
Make sure the cash drawer center lock is unlocked. Make sure the printer is on and
ready to print. Send characters to the printer containing the open code.
Example - For a drawer using BEL (ASCII 7, ^G) as the open code on a DOS computer,
