16.2.7 StandardsforWiring
Cyclone modules automatically sense whether the Ethernet cable in a connection is
wired as straight-through or crossover. You may use either straight-through or crossover
cable to connect a network interface card (NIC), hub, router, or switch to these modules.
For a straight-through cable, use the EIA/TIA-568B wire color-code standard on both
ends. For a crossover cable, use the EIA/TIA-568B wire color-code standard on one end,
and the EIA/TIA-568A wire color-code standard on the other end.
Where you use the Cyclone AC wall adapter
• the power supply output is +24 VDC.
• the power input to the SM is +11.5 VDC to +30 VDC.
• the maximum Ethernet cable run is 328 feet (100 meters).
16.2.8 BestPracticesforCabling
The following practices are essential to the reliability and longevity of cabled connections:
• Use only shielded cables to resist interference.
• For vertical runs, provide cable support and strain relief.
• Include a 2-ft (0.6-m) service loop on each end of the cable to allow for thermal
expansion and contraction and to facilitate terminating the cable again when
needed.
• Include a drip loop to shed water so that most of the water does not reach the
connector at the device.
• Properly crimp all connectors.
• Use dielectric grease on all connectors to resist corrosion.
• Use only shielded connectors to resist interference and corrosion.
16.2.9 RecommendedToolsforWiringConnectors
The following tools may be needed for cabling the AP:
• RJ-11 crimping tool
• RJ-45 crimping tool
• electrician scissors
• wire cutters
• cable testing device.
16.2.10 WiringConnectors
The following diagrams correlate pins to wire colors and illustrate crossovers where
applicable.
Location of Pin 1
Pin 1, relative to the lock tab on the connector of a straight-through cable is located as
