AM-10HD / Aug 2008

Network Connection
The AM-10HD contains its own five port 100Base-T Ethernet switch with one port
available on the outside of the product reserved for user connections. The Ethernet
switch is equipped with auto-sensing; therefore this port will accept either straight-
through or crossover cables.
Networked systems are normally connected to the AM-10HD via “straight” (pin to
pin) CAT5 cable. For typical CAT5 cable pinouts see below. These connections are for
communicating with the configuration computer via a network. If you are connecting
directly between the computer and the AM-10HD with no network in between, it is
normal to use a crossover cable.
