One to three antenna connectors are provided, depending on the model. For all models, the
ISA100.11a antenna connector is on top. The wireless LAN antenna connector 1 on the left side
of the housing is for the wireless LAN single model and the antenna connector 2 is added on the
right side for the wireless LAN redundant model.
The ISA100.11a antenna can be directly mounted on the connector, or remotely connected by
using an extension cable. The wireless LAN antenna(s) must be placed vertically and more than
1 m apart from the ISA100.11a antenna. Thus, they must be connected by using antenna exten-
sion cables.
YFGW510 does not have any switches or buttons that can be mechanically operated from the
outside of the housing.
