1.3 56F827EVM Connections
An interconnection diagram is shown in
for connecting the PC and the external
+12.0V DC power supply or ex5.0V DC lab power supply to the 56F827EVM
board.
Perform the following steps to connect the 56F827EVM cables:
1. Connect the parallel extension cable to the parallel port of the host computer.
2. Connect the other end of the parallel extension cable to P2, shown in
on the 56F827EVM board. This provides the connection which allows the host
computer to control the board.
3. Make sure that the ex12.0V DC 1.2A switching power supply or the
ex5.0V DC 1.0A lab power supply is not plugged into a 120V AC power
source.
4. Connect the 2.1mm output power plug from the external switching power supply
into P1, shown in
, on the 56F827EVM board. Optionally, attach an
ex5.0V DC lab power supply via the 2-pin terminal block, TB1.
5. Apply power to the external power supply. The green Power-On LED, LED7, will
illuminate when power is correctly applied.
