auxiliary components such as mounting plates, labels, gaskets, and fasteners. The
enclosure is powder coated for additional protection against outdoor elements.
IR ports
The FDAP feat
ures a conveniently located IR port used in device commissioning. IR port
is capable of data rates of up to 115.2 KBaud and has a range of 20 cm and beam width
of 20 degrees. IR port is used to communicate with a Provisioning Handheld device used
to commission the FDAP in the field.
Antennas
Th
e FDAP uses dual antenna diversity to improve communication reliability in severe
multi-path environment and communication range. Dual antenna diversity increases
ISA100 coverage range by 1.5 times over Multinodes or wireless field instruments acting
as a repeater. It reduces infrastructure cost and cost per wireless I/O.
FDAP has integral and remote surge arrestors as well as integral and remote antennas.
The antenna selection includes integrated omni-directional antennas and remote mounted
omni-directional antennas. In addition, the FDAP supports a variety of high- and low-
gain directional antennas to provide flexibility in installation and maximum performance
of the wireless system.
