5. Wireless Communication
5.1. Wireless Communication System Configuration
SS method data communication is performed using a wireless card.
Wireless communication between the host computer and BHT is performed via an access point. Please refer to
the “BHT-400B-CE/400BW-CE User’s Manual” for further details.
The table below shows the wireless communication devices on the BHT-400 and communication state transition
for the above system configuration.
Wireless Communication Device Status Communication
Open (power on) Impossible
Checking synchronization with access point Impossible
Synchronization complete Possible
Roaming
Impossible:
If the BHT is not synchronized with an access point.
Possible:
If synchronization with an access point is maintained.
Roaming complete Possible
Close (power off) Impossible
The wireless communication device will consume a significant amount of power if always open. The device should
therefore be closed as much as possible when not in use.
It will, however, take several seconds until the wireless communication device is ready to perform communication
after being opened. Frequent opening and closing of the device will require much time, resulting in poor
responsiveness. The application purposes of user programs should be taken into account when programming.
When the wireless communication device is synchronized with the access point, the BHT displays a
synchronization icon at the LCD screen.
