Switch 3 “Dumb Mode” any open character based on the number of pulses within that ASCII character will open the cash drawer.
CONFIGURATION EXAMPLES Factory Default –This standard configuration is set so that any one (1) ASCII character will open the cash drawer and the RS-232 settings are auto-detected automatically by the cash drawer.
TEST PROCEDURE Factory Default – Any ASCII character will open drawer and RS-232 settings are auto-detected automatically by the cash drawer. Test from DOS: 1.- Configure theCOM port settings by typing: MODE com1:9600,n,8,1 The computer should return the following 2.

CONFIGURATION EXAMPLES Interfacing with powered serial ports – The Multi-serial interface has the ability to receive power from the host and avoid using an external power supply for the cash drawer. This is only possible if the host has a powered serial port with the ability to supply 12VDC 800mA on pin#9. P3 JP1 must be placed on the PWR position (jumper across pins 3 and 2 of JP1) when receiving power via pin 9 from a PC powered serial port.
