APPENDIX B: Extension-Cable Requirements
This cable should be pinned “straight through” (Pin 1
on the Host-Interface Module to Pin 1 on the Device-
Interface Module, Pin 2 to Pin 2, and so on). The pinout
of the RJ-45 connectors on the front of the Modules is
shown in Figure B-1 on the next page.
The color-coding of the twisted pairs in standard
TIA-568A and -568B compliant 4-pair CAT-5 cables is
also shown in Figure B-1. This information will be
important if you are using existing premise wiring as an
extension-cabling component. The X-Tender can be
used with cables compliant with either standard, but the
same standard must be used from one end of your
X-Tender cabling to the other.
As noted elsewhere in this manual, the maximum
length of the extension cable is determined by the speed
of the USB peripheral devices that must be supported
(see
Appendix D
). Full-speed devices such as cameras
and scanners will limit total cable length (including
CAT5 and USB cable) between the computer and any
peripheral to a maximum of 150 ft. (45.7 m). But if
you’re only attaching one or two low-speed devices such
as mice, the total cabling can be as long as 1000 ft.
(304.8 m).
