Power Supply
The external power supply must provide the voltage between 6 and 12 V DC (typical 9 V DC).
Maximum current consumption shouldn't exceed 100 mA when 9 V DC is used. The polarity is not
important. Low voltage DC plug must conform to the DIN 45323 standards:
•
The hole diameter is 1.95 – 2.5 mm (standard: 2.1 mm)
•
The external diameter is 6.2 - 5.5 mm (standard: 5.5 mm)
Note: The emulator must be powered on first, then the target board and vice versa when switching off
the system. First, switch off the target and then the emulator.
Jumpers
All CPU peripheral signals used on the board can be disconnected from the CPU via jumpers. By
removing the jumper, the belonging signal is freed for the user. Note that all CPU signals are available
on the expansion connectors and can be used by the user.
