11a or other protocol communication.
C4.4
Power supply connector Supplies electric power to the YFGW410. C4.2
Synchronization connector Connects two YFGW410 devices to each other for synchronous
communication in the redundancy configuration. Plug the termi-
nating connector into it if the system is not redundant.
C4.4
Field wireless backbone
interface 1 to 4
Connects YFGW510, YFGW610, and the wireless LAN access

DIN rail mounting bracket Secures the YFGW410 onto DIN rails using brackets. C3.3
B3.6 Reset Switch
Resets YFGW410. Hold the Reset switch for more than six seconds, the database in the
YFGW410 is initialized. If the database is initialized, the entire setup information of the device is
cleared. Always make a backup copy of the database before starting its initialization.
