ETHERNET INTERFACE OPTION
Overview
The Ethernet interface option is used as a communication link for the MOSCAD-M units with
Local Area Networks (LAN). The Ethernet interface option supports TCP/IP protocol on a
Twisted Pair (TP) connector, with automatic polarity correction.
External Ethernet Interface Unit
Enclosed in a plastic box, the external Ethernet Interface unit provides an RS232 port for
connection of MOSCAD units to LAN. The external Ethernet unit is powered by 9-15V DC
and has indication LEDs on its front panel. The system software of the external Ethernet unit
can be upgraded using the Ethernet Interface Downloader program.
The following figure depicts the front panel of the Ethernet unit.
