TP connectors
Both RJ-45 ports, the DTP input port and the LAN (Ethernet) port, use twisted pair cables (see figure 4).
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

RJ-45 Connector and Pinout Tables
Patch (straight) cable
—
DTP input 2 port
— Shielded twisted pair (STP) (preferred) or unshielded TP for connection to an Extron DTP transmitter or an
XTP matrix switcher.
LAN port
— Unshielded twisted pair (UTP) or STP for connection of the LAN port to an Ethernet LAN.
Crossover cable
—
LAN port
— UTP or STP for direct connection between the switcher and a connected computer.
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.
LAN port
The LAN port requires Category (CAT) 3, CAT 5e, or CAT 6a unshielded twisted pair (UTP) or shielded twisted pair (STP) cables, crossover
or patch cables.
The cable used depends on your network speed. The switcher LAN port 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.
DTP input port
The DTP input port is compatible with Extron XTP DTP 24 SF/UTP cables or shielded twisted pair (F/UTP, SF/UTP, and S/FTP) cable.
Extron recommends the following practices to achieve full transmission distances up to 330 feet (100 m) and reduce transmission errors.
Use the following Extron XTP DTP 24 SF/UTP cables and connectors for the best performance:
XTP DTP 24/1000 Non-Plenum 1000’ (305 m) spool
22-236-03
XTP DTP 24P/1000 Plenum 1000’ (305 m) spool 22-235-03
XTP DTP 24 Plug Package of 10
101-005-02
NOTE:
When using cable in bundles or conduits, consider the following:
•
Do not exceed 40% fill capacity in conduits.
•
Do not comb the cable for the first 20 meters, where cables are straightened, aligned, and secured in tight bundles.
•
Loosely place cables and limit the use of tie wraps or hook and loop fasteners.
•
Separate twisted pair cables from AC power cables.
