External Ethernet Unit Option
Enclosed in a plastic box, the Ethernet unit provides an RS-232 port for connection of MOSCAD units to
LAN. The external Ethernet unit is powered by 12VDC and has indication LED's on its front panel.
The external Ethernet unit is used with the MOSCAD-NFM, and with CPU modules of the
that are not enhanced with an on-board Ethernet Plug-in option. The Ethernet unit is also used
MOSCAD-L
when Port 3 of MOSCAD or MOSCAD-L is occupied by another Plug-in configuration. Using the
ToolBox program, the external Ethernet unit can be upgraded with new system software. The following
figure describes the front panel of the Ethernet unit.
