CMC 850 User Manual
7.4 Technical Data of the Communication Ports
An overview:
A CMC 850 test set’s standard interface board is the NET-2 board that, in addition to ETH1, ETH2 and
USB, provides one extra USB port for the use of USB peripherals, such as memory sticks, etc.
CMC 850 test sets with a NET-1(x) board can be upgraded with the new NET-2 board.
7.4.1 The NET-2 Board
NET-2: 2 x USB port and Ethernet ports ETH1/ETH2
USB type USB 2.0 high speed up to 480 Mbit/s
USB connector USB type A (for future use of USB peripherals)
Output current 500 mA max.
USB type USB 2.0 high speed up to 480 Mbit/s; USB 1.1-compatible
USB connector USB type B (connect to computer)

ETH port status
LED
Depending on the ETH type of your NET-2 interface board’s
counterpart, the status LED’s behavior varies.
Physical link established, port active:
If there is traffic via an ETH port, the active LEDs start blinking.
