Network Connections
The 6181 Computer accommodates CAT5 twisted pair Ethernet cabling
with RJ45 connectors to support 100 Mbps network data transfer.
Important: Performance degradation of your Ethernet communications
is likely to result if the unit or cables are subjected to
extreme radiated or conducted high-frequency noise. It is
the user's responsibility to properly route cable and
condition input power in order to improve communication
reliability.
Proper cable routing and power conditioning is required
to ensure reliable Ethernet communications in industrial
environments. Rockwell Automation recommends that
all Ethernet cabling be routed through dedicated metal
conduits. Installing ferrite bead filters at cable ends
may also improve reliability.
Replacing the Battery
The 6181 Computer contains a battery to maintain the CMOS settings and
real-time clock. The battery is located in a battery holder on the 6181
Computer backplane. Replace this battery as needed with a Panasonic
battery, part number CR2032, or Allen-Bradley part 6189-1BATT.
ATTENTION: There is a danger of explosion if the
battery is incorrectly replaced. Replace only with the
same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the
manufacturer's instructions.
