Safety messages
NOTICE
This guide provides basic guidelines for the Emerson Wireless 781S Smart Antenna. It does
not provide instructions for diagnostics, maintenance, service, or troubleshooting. Refer to
the Emerson Wireless 1410S Gateway and 781S Smart Antenna Reference Manual for more
information and instructions. The manuals and this guide are available electronically on
Emerson.com/Rosemount. This device complies with Part 15 of the FCC Rules. Operation is
subject to the following conditions. This device may not cause harmful interference. This
device must accept any interference received, including interference that may cause
undesired operation. This device must be installed to ensure a minimum antenna separation
distance of 20 cm from all persons.
WARNING
Failure to follow these installation guidelines could result in death or serious injury.
Ensure only qualified personnel perform the installation.
Explosions could result in death or serious injury.
Installation of the transmitters in a hazardous environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the Product Certifications section for any restrictions associated with a safe installation.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can
cause electrical shock.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause
undesired operation.
This device must be installed to ensure a minimum antenna separation distance of 8 in. (20
cm) from all persons.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or unintentional and
needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting
your system. Restrict physical access by unauthorized personnel to protect end users’ assets.
This is true for all systems used within the facility.

1 Wireless planning
1.1 Power up sequence
The Emerson Wireless Smart Antenna and wireless I/O should be
installed and functioning properly before the power modules are
installed in any wireless field devices. Wireless field devices should
also be powered up in order of proximity from the antenna
beginning with the closest. This will result in a simpler and faster
network installation.
1.2 Antenna location
The antenna should be mounted in a location that allows convenient
access to the host system network (wireless I/O) as well as the
wireless field device network.

1.3 Antenna position
The Emerson 781S Smart Antennas should be positioned vertically
and approximately 3 ft. (1 m) from large structures, buildings, or
conductive surfaces to allow for clear communication to other
devices. If installing multiple antennas, it is important that the
antennas have three feet of horizontal separation from one another.

2 Intended use
2.1 System architecture
The smart antenna must be used in conjunction with a network
manager or network gateway. The smart antenna then functions as a
translator between the wired network and a wireless field network.

3 Physical installation
3.1 Pipe mounting
Procedure
1. Insert U-bolt around 2-in. pipe or mast, through the saddle,
through the L-shaped bracket, and through the washer plate.
2. Use a ½-in. socket-head wrench to fasten the nuts to the U-
bolt.
3. Secure the antenna to the L-shaped bracket with a 5/16-in.
threaded bolt.
4. Use a 5/16-in. wrench to tighten the screw into the housing.
Figure 3-1: Mounting
3.2 Power and data wiring
The Emerson 781S is completely prewired and only needs to be
connected and powered on the Gateway end. The housing is
permanently sealed on the Emerson 781S. In the Gateway:
Prerequisites
If operating with more than one antenna, it is important the antenna
is always connected to the antenna terminal connection 1 port.
Procedure
1. Connect the positive power lead to the “+” power terminal and
the negative power lead to the “–” terminal.
2. Connect the data + lead to the “A (+)” terminal and the data –
lead to the “B (–)” terminal.
3. Connect the grounding wire to the Gateway’s shield
connection.
4. If connecting multiple antennas, repeat this process for
terminal connection 2.

4 Best practices
Twisted shielded pair cable is generally used to wire the serial
connection to the Gateway. The Smart Antenna should be installed in
a central location of the wireless field network so that it has the most
direct connections to wireless devices as possible.
Quick Start Guide December 2022

5 Verify operation
5.1 Emerson 781S Smart Antenna
The antenna has no exterior lights or LCD displays. Therefore, once it
is powered up through the Gateway, its operation must be verified
through the Gateway end of the connection.
5.2 Power up sequence
The second and third LED’s in the Emerson 1410S correlate to the
first and second terminal connections. These lights should be green
when the antenna is connected properly.
5.3 Normal operation
The operation of the WirelessHART® Smart Antenna can be assessed
within the Gateway user interface. The connection can be seen by
allowing the link to be seen as a field device. The operability can be
verified by attempting to connect to a device.
