7 E2 Ethernet Peer Communications
Communication between E2 controller version 2.10 or
greater may now be implemented through an Ethernet net-
work using TCP/IP protocol. To utilize peer connections
over Et
hernet, the following tasks must be performed:
• Upgrade the E2 controller firmware to version 2.10
or greater
.
• Install an industry-standard Ethernet switch(es) or
hub(s)
in an area or areas nearby the E2 controllers.
• Install Ethernet straight-through cabling at the site
from
each E2 to the switch or hub. Installation of
RJ-45 connectors may be necessary to achieve this
goal. The recommended cabling is CAT 5.
7.1 Ethernet IP
Configurations
If using an open network configuration (see Section
7.4.2,
Open Network Layout), contact your IT Network
Administrator for all IP configuration information (IP
Add
ress, Subnet Mask, Primary and Default Gateway set-
tings).
7.2 Hardware
Specifications
Standard industry-accepted practices for wiring of
Ethernet networks are expected. E2 controllers use a star
topology, identical to PC deployment. This includes a
unique “point-to-point” run from a switch or hub to the
controller (see Table 7-1 for hub part numbers for order-
ing). This is done with Category5 (or better) cable. Maxi-
mum distance for a run of 10BaseT is 328 feet (100
met
ers) (11.5 dB loss max).
• The maximum number of controllers allowed on an
IP su
bnet is 20. All E2 controllers that must com-
municate with each other must be on the same sub-
net.
• Recommended Ethernet cabling is CAT 5 (straight-
throug
h cable).
• 328 feet (100 meters) is the maximum distance
allo
wed between devices before a switch or hub
must be added.
