Control Connections

Ethernet Connection

When you connect a computer to the AVT 200HD LAN port, it is vital that you use the correct Ethernet cables, and that they are properly terminated with the correct pinout. Ethernet links use Category (CAT) 5 or 5e unshielded twisted pair (UTP) cables, terminated with RJ-45 connectors. Ethernet cables are limited to a length of 328 feet (100 m).

NOTES: • Do not use standard telephone cables. Telephone cables do not support

Ethernet or Fast Ethernet.

• Do not stretch or bend the cables, because this can cause transmission errors.

A cable that is wired as T568A at one end and T568B at the other (Tx and Rx pairs reversed) is a "crossover" cable.

6	Green	Green
7	White-brown	White-brown
8	Brown	Brown

A cable that is wired the same at both ends is called a "straight-through" cable, because no pin or pair assignments are swapped.

The cable that you use depends on your network speed. The tuner supports both 10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet), 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.

The Ethernet cable must be properly terminated for your application as either a crossover or a straight-through cable.

•Crossover cable — Direct connection between the computer and the AVT 200HD

•Patch (straight-through) cable — Connection of the AVT to an Ethernet LAN

Wiring for RS-232 Control

To connect your computer or control system to the AVT RS-232 connector, use an Extron Universal Control cable (UC50' or UC100'; see “Cables” in the “Reference Information” section for part numbers) or other female 9-pin-to-bare-wire RS-232 cable.

1.Wire the unterminated end of the RS-232 cable to the 5-pole captive screw connector, provided with the AVT. Use only the first three pins on the connector, starting from the left:

a.Connect the transmit wire to the first pin on the left, which plugs into the Tx (Transmit) port.

b.Connect the receive wire to the second pin, which plugs into the Rx (Receive) port.

c.Connect the ground wire to the third pin, which plugs into the ground port, marked with _.
