Cash Drawers; Voltage Setting For The 4689 Dbcs Surepos Receipt Journal Printer - IBM SurePOS 700 Series Hardware Service Manual

Cash drawers

The SurePOS 700 Models 723, E23, 743, C43, E43, 783, E83, 784, C84, and E84
are preconfigured from the factory to work with all IBM cash drawers. In this
automatic mode, the system can detect the difference between IBM 24 V and IBM
38 V cash drawers. Cash drawer port 3A provides an autosensing function for an
IBM cash drawer.
CAUTION:
If you have two connected cash drawers, both drawers must be the same
voltage. Automatic mode sets the cash drawer operating voltage for both
cash drawer ports. If you connect a 24 V cash drawer to port 3A and then
connect a second drawer, it must also be a 24 V drawer. If you are using a
non-IBM drawer, the automatic mode will not work correctly, and damage to
the cash drawer, the system unit, or both is possible.
You can configure the cash drawer voltage (24 V or 38 V) with the configuration
options in the POS configuration setup program or with the jumper override.
Figure 14 shows the location of the cash drawer voltage jumper on the riser card
and a diagram with the position of the jumpers.
