Most of our customers get the ones that are operated
through the Receipt Printer. When the drawer is attached this
way, the printer actually controls the opening of the drawer.
From time to time, we get calls from customers trying to get an MMF
drawers working when the drawer is directly connected to a serial
port.
To open most of these drawers, ANY two characters
passed into the serial port will work. Some of the MMF units
have a switch-selectable character to open the drawer... if the DIP
switches on this type of drawer have not been adjusted, the
default open character is a capital A. Cash drawers of the
switchable type from MMF have an "ND" at the end of the
model number.
To open 75% of all direct connected MMF
cash drawers (especially the ECD232 series), try these codes:
1- Use a code of "1
65"
2- Use a code of "2 65
65"
This should open all MMF drawers requiring any one or
two characters, and also any switchable drawers that have not been
modified
