Communication Cable Wiring
The dual RJ45 network ports on the option board act as a switch to allow for flexibility in cabling topology. For example,
a traditional star network topology may be employed by using a single port on the option board. Alternatively, a daisy-
chained approach may be employed by using both RJ45 ports. This second approach reduces the requirements of central
switch ports.
