Caution when connecting shipboard network to FELCOM251/501
If the FELCOM251/501 is connected to a shipboard network that has a data monitoring system or
the like, the FELCOM251/501 can become unstable when the equipment in the network transmits
large volumes of broadcast packets. If this type of shipboard network is connected to the FEL-
COM251/501, consultation with the network system manager is necessary to provide measures
to ensure the FELCOM251/501 operates stably.
An example of a system that transmits and receives large volumes of broadcast data is a data
monitoring system which has equipment that transfers large data (images, etc.) in short intervals.
One remedy is to connect a router (that is capable of handling large volumes of data) between the
shipboard network and the FELCOM251/501.
