Notes on Wireless LAN
An antenna is built into the V9 series unit for use as a wireless communication antenna. Consider
your usage environment, and if necessary, use Hakko Electronics’ “V9-ANT” external dipole
antenna (optional).
(The built-in antenna of the V9 series unit can be used for wireless LAN communication within 10
meters from the front side of the V9 series unit. For wireless LAN communication around the V9
series unit (360) or more than 10 meters away from the V9 series unit, use of the “V9-ANT” is
recommended.)
Radio waves used by wireless LAN pass through wood and glass, and therefore communication is
possible even if floors and walls are made of wooden or glass material. However, radio waves
cannot penetrate reinforcing rods, metal, or concrete, so if these materials are used
communication is not possible.
Signal intensity can be checked using the Received Signal Strength Indication (RSSI) as a
guideline. Placing the V9 series unit (access point) so that the RSSI value is higher will attain a
more stable communication status.
A low RSSI value, which does not improve by moving the position of the V9 series unit (access
point) or antenna, indicates that the radio wave intensity is weakened due to a long communication
distance or physical obstructions.
The radio waves used for wireless LAN communication are divided into frequency bands called
channels (ch). The V9 series spaces the 2.4 GHz band into 11 channels (1 to 11 ch) at 5 MHz
intervals. However, if the same channel is used or neighboring channels interfere with each other,
communication speed may be reduced.
We recommend selecting channels for access points so that the frequencies do not overlap, such
as 1 ch, 5 ch and 9 ch (when using MONITOUCH as an access point).
Notes on Radio Waves
The wireless LAN function of the V9 series corresponds to “radio equipment for radio stations
(antenna power: 10 mW/MHz or less) of low-power data communication systems” defined by radio
law, and therefore does not require a radio license.
Depending on the peripheral environment or installation conditions, data transmission via wireless
LAN may be unstable compared to wired connections and result in packet loss.
Be sure to check the connection before actual use.
Do not use the wireless LAN function in the following situations.
1) Near a person who uses a cardiac pacemaker: The function may cause electromagnetic
interference in cardiac pacemakers, leading to malfunctions.
2) Near medical devices: The function may cause electromagnetic interference in medical
devices, leading to malfunctions.
3) Near microwaves: Microwaves may cause electromagnetic interference in wireless
communications of the V9 series unit.
