CHAPTER 5
Connecting IP Devices to an IP Network
An IP network requires infrastructure such as Ethernet cable, routers, switches, or Wi-Fi hotspots in
order to work. The following topics discuss the fundamentals of such a network.
Connecting the IP Network
There are two methods to connect a device to an IP Network:
£
Wired (Ethernet connection with the PRI and SEC ports).
£
Wireless (when the Wi-Fi Adapter is connected to the controller).
Wired Network Cable Requirements
Wired networks use commonly available Cat 5e structural cabling fitted with RJ‑45 connectors. If you
make your own patch cable, use Category 5e cable and crimp the RJ‑45 connectors at both ends of
the cable either as T568A or T568B.
Parameter Details
Media
Cat 5e Cable; four (4) pairs of wires with RJ-45 Connectors (standard straight
patch cable)
RJ-45 Pin Configuration
Straight-through wiring. Crimp connectors as per T568A or T568B (both cable
ends must be crimped the same way).
Characteristic impedance 100-130 Ohms
Distributed capacitance Less than 100 pF per meter (30 pF per foot)
Maximum Cat 5e Cable length between IP
devices
328 ft. (100 m) maximum. See About the Integrated Ethernet Switch .
Polarity Polarity sensitive
Multi-drop
Daisy-chain (no T-connections)
ECLYPSE IP devices have two RJ-45 female RJ-45 connectors that provide IP
packet switching to support follow-on devices.
Daisy-chain limit, APEX Up to 20 devices can be daisy-chained per network switch port.
Daisy-chain limit, ECY-CSC Up to 20 devices can be daisy-chained per network switch port.
Daisy-chain limit, ECY-VAV, ECY-303 and
ECY-PTU Controllers
Up to 50 devices can be daisy-chained per network switch port.
Spanning Tree Protocol (STP) limit, ECY-
VAV, ECY-303 and ECY-PTU Controllers Distech Controls recommends a maximum of 25 devices to be connected in a ring
and must use two network switch ports.
