Extron Control System Comm-Link cable
Wire specifications for Extron Comm-Link cable (see figure 13) are as follows:
• A (red) = 18 American Wire Gauge (AWG)
• B (violet or blue) = 22 AWG (grouped and shielded)
•
C (white) = 22 AWG
• D (drain) = 24 AWG
• E (black) = 18 AWG
NOTE: Comm-Link cable was designed for use with MKP control panels.

TP Cable Termination and Recommendations
It is vital that you use the correct Ethernet cables, and that they 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 m).
ATTENTION:
• Do not use standard telephone cables. Telephone cables do not support Ethernet
or Fast Ethernet.
•
Ne pas utiliser de câbles téléphone standard. Les câbles de téléphone ne sont pas
compatibles avec les liaisons Ethernet ou Fast Ethernet.
• Do not stretch or bend cables. This can cause transmission errors.
• Ne pas étirer ou plier les câbles. Cela pourrait provoquer des erreurs de
transmission.
