4E-FM installation and user guide
4.1.3. Network cabling
4EVAC network features a full duplex RS-422 data link and 24V DC power to remote devices.
If you're building a distributed system using the 4EVAC network, you should make physical links between
devices using the right cables. The cabling should meet the following requirements:
1.
Crossover twisted-pair cable (compatible with Ethernet crossover)
2.
CAT5e or higher for maximum distance of 250m.
3.
Non-CAT / lower than CAT5e: 250m not guaranteed.
4. Shield required (at least FTP)
NOTE: If you use a straight cable, the device will power up but the Tx/Rx data terminals will not be properly
connected. This will result in a communication fault between L-Net device and C500 main unit. The L-Net
device will not be able to initialize, and thus will remain in its boot-sequence, not operational.
Caution! Use only crossover cables and keep the correct pinout! Connecting power pins to data pins will
damage the network port.
