An RJ45 connector is used for the 10Mbs Ethernet connection
supporting TCP/IP communications via standard IPV4 addressing.
The IP address may be configured for static addressing or dynamic
addressing (set using a DHCP server).
Any serial port protocols may be accessed over Ethernet in addition to
the serial port. Up to three simultaneous connections are allowed per
protocol.
The external accessory connector is not used in the Model 5014i
analyzer.
This port is used in other models to communicate with smart external
devices that may be mounted hundreds of feet from the analyzer using
an RS-485 electrical interface.
