APPENDIX A: The USB X-Tender’s Connectors
The USB cables supplied with the USB X-Tender, like
all USB cables used for normal host
↔
peripheral
communication, have a Type A plug on one end and a
Type B plug on the other.
Both types of USB connector have four pins, although
the pins are arranged differently. In each case, Pin 1
c5 VDC, Pin 2 carries the negative data signal
(“–Data”), Pin 3 carries the positive data signal
(“+Data”), and Pin 4 carries ground.
RJ-45
8-pin RJ-45 connectors are currently
the most widely used connectors in
computer networks, largely because
they’re modular (easy to plug and
unplug) and they’re ideally suited for
use with Category 5 (CAT5) wiring.
The Host-Interface and Device-
Interface Modules both have a single
RJ-45 female jack (shown here); you’ll
run a CAT5 cable terminated with
matching RJ-45 male plugs between
these jacks on the two Modules.
For a pinout of this connector and
the CAT5 cabling, see
Appendix B
