Receipt Journal printer voltage must set to 24 V. All other RS-485 printers will work
correctly with the SurePOS 700 at the default setting of 38 V.
To configure the printer voltage to 24 V, set jumpers JP1 and JP2 to one of the
values shown in Table 9.
Table 9 provides the correct jumper settings for 24 V and 38 V printers.

Powered USB connectors
The powered USB connectors provide additional power from the host to devices
that require more power than is available from the USB standard Type A connector.
As shown in Figure 16 on page 24, the powered USB receptacle consists of two
connectors that are integrated within a common shielded housing. These two
connectors are stacked vertically inside the common housing.
The upper connector (
A
in Figure 16 on page 24) contains four contacts that are
used for powering the attached device. The lower connector (
B
in Figure 16 on
page 24) is a fully compliant USB Type A connector capable of mating with either a
standard USB Type A plug or a powered USB plug. In other words, the bottom half
of the connectors are standard USB Type A ports to which USB I/O devices can be
attached.
Note: On SurePort cards, the connector is mounted upside down; on the front USB
port, the connector is mounted sideways.
