Ethernet
The 6200 has the ability to be controlled by a host computer via
Ethernet. This requires the host computer to be connected to the
6200 either by an Ethernet switch or a crossover cable. It also requires
that the 6200 as well as the host computer have the proper network
configuration.
Note:Alwayschooseaswitchinlieuofastandardhub.Thisis
especially important when mixing 10 Base-T and 100 Base-T devices in
a data-intensive environment.
Network configuration of the 6200:
Connectingtothe6200fromahostcomputeronthesameLAN,both
the6200andthehostcomputerrequirethefollowing3items:
1. IP Address - The unique address of a node on a network.

different subnet).
If you are putting the 6200 on an existing network, a network
administrator should be able to provide the above information. For
security reasons, it is not recommended to put the 6200 directly on
the internet. If you do, a network administrator or your Internet Service
Provider can provide the above information. If you are building your
own separate network, you may consider using an IP Address from one
ofthe“Private-Use”networksnotedinRFC-1918:
