Network ports
The Impact controller offers 5 ports (RJ-45) for network connections between distributed parts of the 4EVAC
Voice Evacuation System:
•
2 x G-Net ports (global network)
•
3 x L-Net ports (local network)
The 4EVAC network features a full duplex RS-422 data link and DC power to remote devices.
NOTE: 4EVAC network is not Ethernet!
If you are building a distributed system using a 4EVAC network, you should make physical links between
devices using the correct type of cables. The cabling should meet following requirements:
1.
Crossover twisted-pair cable (compatible with Ethernet crossover)
2.
CAT5e or higher for a maximum distance of 250m.
3.
Non-CAT / lower than CAT5e: 250m not guaranteed.
4.
Shield required (at least FTP) for L-Net
Caution! Use only crossover cables and keep the correct pinout! Connecting power pins to data pins will
damage the network port.
