F2.2
Reset switch Resets the YFGW410. B3.6
Shutdown switch Shuts down the YFGW410. B3.7
Maintenance interface Connects the Field Wireless Management Console for setup and
maintenance of a field wireless network.
The PC, that has the FieldMate for setup and management of
field wireless devices via wireless network, can also be con-
nected (if used for the system without CENTUM VP).
C4.4
Serial port Used for YFGW410 maintenance only. (Do not use this port dur-
ing normal network configuration and operation.)
C4.1
Field network interface 1 to 3 Connects to the host system that uses the Modbus/TCP, ISA100.
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
point to configure the field wireless backbone.
C4.4
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.
IMPORTANT
When initializing the database, don’t power off until RDY LED becomes green. Otherwise initiali-
zation will be failed and YFGW410 may not work correctly.
B3.7 Shutdown Switch
Shuts down YFGW410. Hold the Shutdown switch more than six seconds. Once shut down the
YFGW410, start it again by turning the power supply OFF first, and then turn it ON again.
