2.2 Connections of emulator
In the host-target machine cross development model, through debugging
device the host is connected with target machine, and conducts download and
debugging. UNetICE is a JTAG emulator, connected to JTAG port of target board
via a 20-pin IDC straight-through cable (1-1, 2-2, ... 20-20), connected to host
through USB or Ethernet port. User can select an appropriate connecting way
according to their requirement.
USB connection type
USB (Universal Serial Bus) is a new port technology in PC application, it
provides power supply and high-speed telecom channels for peripheral
equipment, bringing users a lot of convenience.

The host can be connected to UNetICE emulator through a special USB cable.
See figure below, the A-type male port in the left is connected with the A-type
female port of host, the B-type male port in the right is connected with the B-type
female port of target board. If you need to use USB as power supply device, you
can adjust the power switch.
Figure 2-3 USB cable
Ethernet connection type
There are two ways of Ethernet connection, one is standard Ethernet
connection, use two parallel network cable (see figure below) to connect host,
target board and HUB to constitute a LAN. The other way is using one cross cable
to connect the host and target machine directly.
Figure 2-4 Ethernet cable
Power supply
User can choose 5V power supply through USB port by operating power
switch; or alternatively choose 6~9V external power supply. In external power
supply socket, the inside is positive, the outside is negative, see the figure
