Cash Drawers; Cash Drawer Jumper Settings - IBM 4800-741 Hardware Service Manual

Cash drawers

The SurePOS 720 are preconfigured from the factory to work correctly with all IBM
cash drawers. In this automatic mode, the system can correctly detect the
difference between IBM 24-V and IBM 38-V cash drawers. Cash drawer port 3A
provides auto-sensing function for an IBM cash drawer.
Note: Automatic mode sets the cash drawer operating voltage for both cash drawer
If you are using a non-IBM drawer, the automatic mode will not work correctly, and
damage to either the cash drawer, system unit, or both is possible. If a customer
has two connected cash drawers, both drawers must be the same voltage.
You can configure the cash drawer voltage (24 V or 38 V) by using the
configuration options on the POS configuration setup program or with the jumper
override. Figure 11 shows the location of the cash drawer voltage jumper on the
riser card and a diagram with the position of the jumpers.
