bulkhead connectors for antenna spatial diversity in the FDAP2 radios. The half-inch rigid
conduit hub has a gasket to seal out water and dust. A rigid conduit hub, internal and
external ground studs, and a removable cover are provided for field installation. Externally
accessible Infrared (IR) port allows the device to be commissioned in the field. Three status
LEDs provide information about power, device health, and communication. The enclosure
may be mounted on a pole or on a flat surface such as a wall using the available optional
mounting brackets. The enclosure measures approximately 20 cm x 13 cm x 7 cm
(L x W x H).
Fig. 3. Physical description of FDAP
IR port
The FDAP2 has an externally accessible IR port that is used for communicating with the
Provisioning Handheld device. The Provisioning Handheld device is used for
commissioning the FDAP2, reading, and setting the various FDAP2 parameters. The IR
port has a range of 20 cm and a beam width of 20 degrees.
Communication radio
The FDAP2 has wireless compliant radios that operate in the 2.4 GHz ISM band. It uses
spatial antenna diversity with sophisticated error correction schemes to improve
communication and increase coverage in a typical industrial complex where multi-path
propagation is prevalent.
Antennas
The FDAP2 uses dual antenna diversity to improve communication reliability in severe
multi-path environments. This helps in improving radio coverage and provides robust
communication links thereby reducing infrastructure costs and cost per wireless field
device.
The FDAP2 has integral omni-directional antennas and it also supports a variety of high-
and low-gain directional and omni-directional antennas to provide flexibility in installation
