System Description
I/O Components
Ethernet Connection
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.
External Accessory
The external accessory connector is not used in the Model 146i calibrator.
Connector
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.
