Usage.of.F9092EY
1.1.
Purpose.of.using.F9092EY
To make full use of field wireless devices, the optimal installation layout is required. FN110 is more sensitive to the
surrounding environment than other Yokogawa field wireless devices because it has a built-in antenna.
F9092EY reduces the effects of the surrounding environment to the communication quality, making an installa-
tion easier. Therefore, F9092EY offers the same communication quality and allows the same installation point
optimization as other Yokogawa field wireless devices.
1.2.
Guidelines.on.whether.using.F9092EY.is.
necessary
(1).Newly.installed.FN110
• Using F9092EY is recommended.
(2).Existing.FN110
• If communication quality has been satisfactory, F9092EY is not necessary.
• When communication quality is not good (i.e. PER is high), use of F9092EY may improve communication
quality.
(3).New.FN110.for.replacement.of.existing.FN110
• Even if the old FN110 does not use F9092EY, using F9092EY is recommended because the replacement
may affect the communication quality.
• If the old FN110 uses F9092EY, continue to use F9092EY.
(4).FN110.for.a.site.survey
• Using F9092EY is recommended. If a site survey is carried out using F9092EY, be sure to use F9092EY at
the actual installation.
