ETHERNET COMMUNICATION
An Ethernet crossover cable (RJ-45 connector, 2.8 meter) is included with the Micro-GC.
The crossover cable must be used to control the Micro-GC in a peer-to-peer communication
(see
Inside View on page 14 ).
This requires IP addresses in the same range for computer and Micro-GC. Only the most right
IP segment must be different.
In case both the computer as well as the Micro-GC are connected to a (local) network this cable
cannot be used for control of the Micro-GC.
However this crossover cable must be used if a new IP address has to be assigned to the
Micro-GC. Once the IP address is assigned you can disconnect the crossover cable and
connect computer and Micro-GC both to a (local) network.
Peer-to-peer: single instrument
Crossover Cable
Workstation
Any IP-address allowed
490-GC
