Control Connector Wiring
NOTES:
•
The IR line pair and the RS-232 line pair must each cross once between this
connector and the source or destination.
•
The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
•
If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
•
If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled
out even if tightly fastened by the captive screws.
•
Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
LAN and Ext connector
The encoder NAV 1G/PoE+ port supports 1000Mbps (1000base T — Gigabit Ethernet),
half-duplex and full-duplex Ethernet connections. It is vital that your Ethernet cable be the
correct cable type and that it be properly terminated with the correct pinout. Ethernet links
use Category (CAT) 5e or CAT 6, unshielded twisted pair (UTP) or shielded twisted pair
(STP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of
328 feet (100 meters).
NOTES:
•
A CAT 5e cabling infrastructure is the minimum acceptable to support a NAV
system. Anything less is insufficient.
•
Do not stretch or bend cables. Transmission errors can occur.
The Ethernet cable must be terminated as a patch (straight-through) cable and must be
properly terminated in accordance with the
TIA/EIA
T568-B
wiring standard (see figure 9).
