Section 2-1 Installation 2-1 Installation Make sure that the radio wave conditions at the installation site are favorable before actually installing the WT30 Terminals.
Section 2-1 Installation If the Antennas are installed in locations with relatively high ceilings and a lot of open space, even if there is no direct line of sight between the Antennas, if one of the Antennas is installed in a high location, communications may still be possible via radio waves that are reflected off the ceiling. 2. Install in as high a location as possible.
Section 2-1 Installation 6. Separate different sets of Antennas as much as possible. If different sets of Antennas are close to each other, they will influence each other and thereby influence wireless communications, causing an increase in the number of retries, and a reduction in the possible communications distance. Separate different sets of Antennas by at least 2 m if possible. 7. Do not install the two Magnet-base Antennas close to each other.

Other Points about Magnet-base Antennas • The magnet on the Magnet-base Antenna is very strong. Do not remove the Antenna by pulling on the cover or cable. Doing so may damage the Antenna. Always hold the base when handling the Antenna.
Section 2-1 Installation 13. Do not subject the Antenna to shock. Do not install the Antenna in a location in which it may be hit by other objects. If installation in such a location is required, take sufficient measures to protect the Antenna. Subjecting the Antenna to strong shock may cause either external or internal damage to the Antenna. Internal damage that is not necessarily externally visible may prevent communications, such as broken wires.

Section 4-1 Relay Function 4-1 Relay Function The relay function extends the communications distance using an I/O Slave Station as a Relay Station. Even if equipment is relocated, making communications between the Serial Master Station and I/O Slave Stations unstable or resulting in a disconnection, the communications path can be switched, enabling communications to continue automatically via a Relay Station.
Section 4-1 Relay Function Switching Communications Path The communications path can be automatically switched to perform communications via a Relay Station. With this function, even if an I/O Slave Station moves out of the communications area with the Serial Master Station, communications will continue after switching the communications path.
