NET COM on Advantage IV transmitters is connected to earth ground.
Do not connect NET COM on EB-Flow2 transmitters to earth ground.
2.1.2.2.3. All RS-485 Networks
All network devices are on a single “daisy-chain”.
The first device on the chain is properly terminated for “fail safe bias”, preferred, or “end of line”.
The first device on the chain is often the B.A.S. control panel. If the first device on the chain is not the
B.A.S. controller and fail-safe bias is required, EBTRON Advantage IV transmitters can be configured
for the fail-safe bias termination. See appropriate wiring diagram for the transmitter provided in
Section 1.
The last device on the chain is properly terminated for “end of line”.
If an EBTRON transmitter is the last device on the chain, set the end of line termination. See
appropriate wiring diagram for the transmitter provided in Section 1.
Failure to properly terminate the network will result in network instability or network failure.
2.1.2.3. TRANSMITTERS WITH AN ETHERNET NETWORK CONNECTION
Inspect and verify the following if the network connection is used:
CAT5 or higher cable has been used for the Ethernet connection.
The cables have been properly terminated with RJ-45 connectors and the connections have been
tested prior to connection to the transmitter.
Use of an improperly wired RJ-45 connector may cause damage to the Ethernet output circuit of the
transmitter.
2.1.2.4. TRANSMITTERS WITH A LON NETWORK CONNECTION
Lon transmitters use the “free topology” network.
Inspect and verify the following if the network connection is used:
The network wire is as specified by Echelon (typically Belden 8471 cable or equivalent).
The network wire pair has been properly terminated at the transmitter (polarity insensitive).
2.1.2.5. TRANSMITTERS WITH AN EBTRON RF-LINK CONNECTION
Transmitters with an EBTRON RF-Link card can communicate with EBTRON Commissioner or other RF-Link
compatible EBTRON master transceivers.
Inspect and verify the following if the RF-Link card is provided:
The antenna has been field installed and pointing upward. Install by screwing it into the SMA
connector located on the top left of the transmitter enclosure.
Although the wireless radio does not require a clear line of sight between the transmitter and
receiving device, a large mass of metal or another RF interference source could degrade signal
strength and adversely affect the RF transmission. Note any obstructions between the transmitter
