Make sure that the radio wave conditions at the installation site are favorable
before actually installing the WT30 Terminals.
Do not install this device in locations such as the following:
• Areas exposed to direct sunlight
• Areas with extremely high humidity
• Near devices such as televisions, radios, and computers
• Near devices that emit sparks, such as motors, drills, and welding equip-
ment
• Near strong magnets
• Near fluorescent lights
• Inside metal panels or locations surrounded by metal or concrete
If the WT30 Terminal is installed in a metal panel, be sure to mount the entire
Antenna outside the panel where there are no interfering objects.
• Install the Antennas for the Serial Master Station and I/O Slave Stations
or the Relay Stations and I/O Slave Stations in parallel.
• Install the Antennas as far away as possible from and not parallel to elec-
tric wires or metal panels.
• Use wood screws when installing the WT30 on a wooden surface.
• Use M4 screws for installation if the provided installation screws are not
used.
• Communications are not possible if the Terminals is too close to each
other (within 1 m). Make sure that sufficient distance is provided between
WT30 Terminals.
The WT30 uses radio waves with a frequency of 2.4 GHz, which is very high.
High-frequency waves exhibit strong rectilinear propagation and are reflected
easily. For this reason, careful consideration of the Antenna installation posi-
tion is required to achieve optimum wireless performance.
1. If possible, install Antennas so that there is a direct line of sight between
them.
High-frequency waves, which exhibit strong rectilinear propagation, are
used and so it is difficult for the waves to reach areas that are not in a direct
line of sight, as shown in the following diagram. This is a particularly impor-
tant point for communications at long distances (e.g., exceeding 50 m or
60 m.)
