How to open cash drawer

What is the cash draw lock connected to? How do you usually open it?

you could use one of the unused 232 control lines to activate the release solenoid,

for programming one need to know the operating system and the compiler.

cash drawer opens frequently.(it's in my shop). os is windows xp and software is written using C++

can anybody knows to write a program to open cash drawer when COM port is active (it mean when printing a bill)

Please open the rs232 connector at the printer side and determine the pin numbers to what the solenoid is connected to.

it has 4 pins (the socket is like as telephone socket)

Hi schathuranga,

This is vb code to open cash drawer. Make sure the cash drawer connect via a cable RJ11 from the printer.

Good luck.
