Cash Drawer Installation
Before connecting the cash drawer to the MP-3525, please make sure the drive voltage and cable
pin assignment of the cash drawer matches the definition of the cash drawer port of MP-3525.
Please refer to the mother board (FEB-7100) manual GPIO part for more information. For
programmers, please refer to the folder “Utility”
“Pos Utility” “Cash Drawer” in the driver CD,
where you may find the test programs and DLL Library files for your application.
Plug cash drawer cable into the cash drawer port.
Note: If the cash drawer cannot be detected by the system, please refer to troubleshooting.
Up to two cash drawers may be driven from this port. Driving voltage of the solenoid is DC+12V.
I/O port 2F is used for drawer operation. A test program is supplied, for Linux and Windows,
source code of which is available on request by software developers.
To test for drawer open, read port 2F, if bit 0=1 then drawer is open, if bit 0=0 drawer is closed.
Before testing the cash drawer function, ensure to initiate the GPIO port first referring to the
command sets below:
initGPIO=2e,87,2e,87,2e,07,2f,07,2e,f1
( 2e stands for the address while ‘87’, ‘07’, ‘f1’ stands for the value to the address. All the values here are
hexadecimal.)
