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 opposite

Any damage caused to the programmer through inadequate

earthing is not covered under warranty.

Hardware Installation Instructions

Overview

The GEMINI-1 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.
