M-S Cash Drawer Corporation
KSI type interface instructions
Introduction
The M-S Cash Drawer KSI trigger board enables the cash drawer to be controlled
directly by the compatible PC's serial port. Two cable configurations are available
allowing the drawer to be operated as a "dead-end" device or as a "parasite" device.
The interface is programmable allowing opening character selection. Multiple drawers
may be "Daisy Chained" together. The interface is capable of reporting the drawer's
status.
Cable Options
Two cable configurations are available: Dead-End and Parasite.
Dead-End cables are available with either a DB9 pin or a DB25 pin female connector for
direct connection to the serial port. A DB25 pin male version is also available allowing
connection to a DCE type auxiliary port (i.e. Wyse terminal).
