Figure 11 shows the USB SurePort adapter with the base SurePort adapter
configuration.

12 V powered USB ports
Note: The letters shown on the USB connectors are used to identify the
connector space and the order of connection per adapter card. As an
example, for each adapter card, the system first recognizes a device
connected to USB port A before recognizing the device connected to
USB port B. This autosensing feature applies to both adapter cards;
therefore, the system could recognize adapter card 1, USB port B,
then C, before recognizing the USB port D on adapter card 2.

IBM cash drawer ports
Note: Port 3A detects an IBM cash drawer automatically. If you use
non-IBM cash drawers, read the voltage considerations described in
“Cash drawers” on page 22.
