USB X-TENDER
Appendix A:
The USB X-Tender’s Connectors
The USB X-Tender has three different types of data
connectors: USB Type A, USB Type B, and RJ-45.
USB Type A
USB hosts, and the ends of USB cables
that attach to hosts, have Type A
connectors. The USB ports on the
X-Tender’s Device-Interface Module
are Type A female (shown here), just
like those on a host computer. The
cables from USB peripherals have
matching Type A male plugs.
USB Type B
USB peripherals, and the ends of USB
cables that attach to peripherals, have
Type B connectors. The USB ports on
the X-Tender’s Host-Interface Module
are Type B female (shown here), just
like the “To Computer” ports on a
USB hub. The cable from the USB
host computer has a matching Type B
male plug.
