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.
The Ethernet indication LEDs are:
•
TX - Ethernet Transmit
•
RX - Ethernet Receive
•
LI - Ethernet Link Integrity
The RS232 indication LEDs are:
•
TX - RS232 Transmit
•
RX - RS232 Receive
•
CM - RS232 Channel
