CABLING
The RF environment the Subscriber Module operates in often will permit use of unshielded
cable.
However, in cases where cable interference issues are suspected, or as part of A/B comparisons
to
debug field problems, use of shielded cable with Subscriber Modules may be
warranted.
It is strongly recommended to use shielded cable for all Stinger infrastructure cabling
associated
with Backhauls, Access Points, and Cluster Management Modules. The environment
these
modules operate in often has significant or unknown or varying RF energy, and experience
has
been that the additional cost of shielded cabling is more than compensated by
predictable
operation and reduced debugging and support
costs.
The following information describes the wiring standards for installing a Stinger system.
All
diagrams use the EIA/TIA 568B color
standard.
Currently shipping modules auto-sense the Ethernet cable type – either RJ-45 straight-thru cable
or
RJ-45 crossover cable can be used to connect a network interface card (NIC), hub, router,
or
switch to a
module.
Very early modules did not auto-sense. In cases where older modules are
used:
•
When connecting a Stinger device directly to a network interface card
(NIC)
use a RJ-45 straight-thru
cable.
•
When connecting a Stinger device directly to a hub, switch, or router use
a
RJ-45 crossover
cable.
When using the Stinger AC wall adapter the +V is +11.5VDC to +30VDC with a nominal value
of
+24 VDC, and the maximum Ethernet cable run with the AC wall adapter is 328 feet (100
meters).
