1.3 Power Supply - Selection Jumper
If you have version
‘V1.1’
of the
‘ARM ISP Cable’
then you will find a
‘3-way Jumper Link’
on the
circuit board. This jumper is used to configure how the Programmer and Target System are powered.
The jumper is labelled
‘IN’
and
‘OUT’
on the actual PCB. Please refer to the table below to select the
correct powering method for your application.

•
The Target System voltage is fed directly to the
programmer and will be used to power the
programmer.
3.0 – 5.0V

Programmer powers the Target System at 3.3V (default)
•
The programmer must be powered from an external
power supply via the DC Jack Socket in the range of
3.5 to 5.0V.
•
A 3.3V regulator on the
‘NXP LPC2xxx ISP Cable’
then feeds 3.3V down to the Target System.
3.3V
Warning!
If you select link position
‘IN’
and then input +5V into the DC Jack Socket of the programmer, this will
feed +5V directly to the Target System. This +5V could damage circuitry on the Target System if it is
only designed to run at 3.3V.
1.4 Cable Installation Instructions
These instructions detail how to fit the
‘ARM ISP Cable’
to an Epsilon5, FS2003 or EPSILON5-MK4
programmer.
Instructions:
•
The
‘ARM Programming Cable’
has a small circuit board on one end which plugs into the
ISP headers inside the programmer. On the other end it features a 20-way IDC plug.
•
Remove the top cover of the programmer.
•
Make sure the both the programmer and your Target System are powered OFF.
•
Plug the circuit board end of the
‘ARM Programming Cable’
into the programmer ISP
headers – see example picture of cable fitted to FS2003 / EPSILON5-MK4 programmer
below.
•
Make sure that the 2 x 10-way connectors are correctly aligned so that the 2-way header J9
aligns with the 2-way header on the cable.
•
Decide on how you wish to power the programmer and Target Board – set the
‘Power Supply
– Selection Jumper’
accordingly – see section 1.3
•
You are now ready to program an ARM device via JTAG.
