Figure A2-1 Minimum configuration Figure A2-2 YFGW510-redundant configuration
Figure A2-1 shows the minimum configuration with a single YFGW510, and Figure A2-2 shows
the YFGW510-redundant configuration supported the Duocast technology (each field wireless
device communicates with two YFGW510s).
The field wireless backbone network consists of the YFGW410, the YFGW510 and the
YFGW610. Any of the following connection methods can be selected.
1. Metal network connection (100BASE-TX)
2. Optical fiber network connection (100BASE-FX)
YFGW610 must be installed between YFGW510 and YFGW410 for optical fiber network
connection to convert it to metal network connection.
3. Wireless LAN connection
Recommended access points for wireless LAN must be installed between YFGW510 and
YFGW410 for wireless LAN connection to convert it to metal network connection.
For recommended wireless LAN access points, see the User’s Manual of YFGW410 (IM
01W02D01-01EN).
