RS-232 and IR Connectors
Figure 6 shows how to wire the Control (RS-232 and IR) and Remote (RS-232) connectors.
CONTROL
Figure 6.
NOTES:
•
The IR Tx and Rx line pair and the RS-232 Tx and Rx line pair must each cross
once between this connector and the source or destination.
•
The length and preparation of exposed wires is important (see the audio connector
NOTES above for details).
TP Cable Termination and Recommendations
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) 3, 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:
•
Do not use standard telephone cables. Telephone cables do not support Ethernet
or Fast Ethernet.
•
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The unit supports:
10 Mbps (10Base-T — Ethernet), 100 Mbps (100Base-T — Fast Ethernet), and
1000 Mbps (1000Base-T — IEEE 802.3ab) half-duplex and full-duplex Ethernet
connections.
•
10Base-T Ethernet requires CAT 3 UTP or STP cable at minimum.
•
100Base-T Fast Ethernet requires CAT 5e UTP or STP cable at minimum.
•
1000Base-T Gigabit Ethernet requires CAT 5, CAT 5e, CAT 6, or CAT 7 UTP or STP
cable.
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 7).
