Antennas - Honeywell OW-CDX050 User Manual

•
One field I/O radio which communicates with the various wireless field devices. A
multinode will contain one of two radio types:
−
A FHSS radio which uses Frequency Hopping Spread Spectrum modulation as
the communications protocol.
−
A DSSS radio which uses a Direct Sequence Spread Spectrum modulation as the
communication procotol and is based on the IEEE 802.15.4 standard.

Antennas

The multinode is supplied with three 5dBi omni-directional antennas. Two antennas are
identical and are installed to the MESH and AP connectors located on the top of the unit.
These antennas are used with the 802.11 radios for client and wireless mesh
communications. The third antenna is used with the field I/O radio for communication
with the field devices and is installed on the FIELD I/O ANTENNA (or FHSS
ANTENNA) connector.
Note: The 802.11 antennas and the field I/O radio antenna are not interchangeable.
A number of optional high gain antennas from various manufacturers also have been
qualified for use with the multinode. Antenna selection is based on a number of factors
such as frequency range, overall antenna output, and country regulations. Antenna
options also include installation of the antenna remote from the multinode. When using
one of these antennas, you must manually adjust the transmit power of the radios in the
multinode.
ATTENTION
Multinodes must be professionally installed in accordance with the
requirements specified in the OneWireless Multinode Agency Compliance
Professional Installation Guide.
If you are not using the wireless access point function then you do not need to connect
the client antenna. Make sure during your configuration set up that you go to the
Wireless Access Point-General
Also ensure that any unused antenna port is securely covered with the attached protection
caps.
NOTE: If any part of the multinode or antenna is located outdoors, a lightning arrestor
must be installed between the unit and the antenna. See the
