Micro-ISP
Hardware Installation Instructions
Overview
The Micro-ISP programmer connects to any spare PC serial (COM) port. If you only have
one serial port and this is in use for e.g. a modem, it may be possible to add another serial
port to your machine by inserting a new I/O card.
For further hardware installation help, please refer to the: Installation Troubleshooting Guide
Warning !
To avoid catastrophic damage to PC, programmer or target system:
• Ensure that both your target system and PC are connected to a common earth point.
• Make sure that all interconnections are made before applying power to PC and target
system.
• If you are using a laptop or PC which is not connected to mains earth, it is
recommended that you make a hard-wired connection from the COM port D-connector
shell and the target system to a common earth point.
• Avoid plugging and unplugging ISP connector while either the PC or target system is
powered up.
• Please ensure that any
devices connected to the
user target system are also
properly grounded to the
same common earth point.
• Please see Diagram
Any damage caused to the programmer through inadequate earthing is not
covered under warranty
1 Connect the serial cable provided to a spare COM port on the PC using the 9-25 way
adaptor if necessary.
2 Connect the Micro-ISP to the other end of the serial cable.
3 Connect IDC plug at the end of the serial programming cable into the 10-way IDC header
on the user target board (not supplied).
4 Apply power to the target board. Please ensure that the target system is powered up.
The programmer will not operate unless a Vcc in the specified range is applied on pin 1 of
the IDC connector. (The Micro-ISP draws its power from the target)
