Figure B1-3 Wireless LAN redundant model
As shown above, the functions of the field wireless backbone interface differ depending on
model.
YFGW510 with the 100BASE-FX model is equipped with a media converting board for metal
network/optical fiber network. The metal network cable and optical fiber network cable cannot be
used at the same time.
In the wireless LAN client model, neither metal network cable nor optical fiber network cable can
be used. Wireless LAN client model indicates both of the wireless LAN single model and the wire-
less LAN redundant model.
YFGW510 with the wireless LAN redundant model uses either wireless LAN port as a communi-
cation path. For the selection of a wireless LAN port and the conditions for switching communica-
tion paths, see D3.7 Setting of WLAN Redundancy.
ISA100.11a BBR of the field wireless network interface is for the field wireless communication.
Initial communication shown in the block diagram is the function of setting parameters. It com-
municates to the Field Wireless Access Point Setup Tool via an infrared port through the glass
window on the front face of YFGW510.
