6.5 Technical Data of the Communication Ports
The first versions of the CMC 356 test sets were delivered with a NET-1
board that contained two different Ethernet ports: ETH1, a10/100Base-TX
Ethernet port and ETH2, a 100Base-FX (optical fiber) Ethernet port.
With the introduction of the front panel control device CMControl, the
CMC 356 test sets were then equipped with a NET-1B board that contained
two identical 10/100Base-TX PoE (Power over Ethernet) Ethernet ports
ETH1 and ETH2.
Today, the standard interface is the NET-1C board that, in addition to ETH1
and ETH2, provides an additional USB port.
CMC 356 test sets with NET-1 board can be upgraded with the new NET-1C
board to be able to communicate with the new CMControl and have
Ethernet as well as USB access at the same time.
