The GEMINI-1 programmer plugs into a
spare serial (com) port of any IBM
compatible PC including the majority of
laptop machines.
To select the Correct Serial Port
i.
From the menu bar select <Options>
<Select Port>
The available COM ports on your computer
are now displayed.
ii.
Select the COM port to which the
programmer is connected
ii.
Select the desired target microcontroller
baud rate e.g. 9,600K
The baud rate is the maximum baud
rate which the target microcontroller
can reliably communicate at.
See Device programming section for
further information.
iii.
Select <Test>
A programmer communications test is
now performed.
This tests both the programmer, cable and
PC serial port. It does not communicate
with the target microcontroller
Communications Test Pass
The programmer has been detected OK by
the GEMINI software. If you now <Cancel>
out of the <Test Port> dialogue box, the
words ‘ON LINE’ should now be displayed at
the bottom right of the GEMINI Window.
Installation is complete and the programmer
should now be ready to-use.
Please Note
This test has not verified that the
programmer can communicate with the
target microcontroller.
Communications Test Fail
The programmer was not detected on the
COM port selected. Please check that the
correct COM port was selected, and if not,
repeat the <Select Port> < Test> operation.
If your PC is not fast enough to operate at
the default highest communication speed,
it may be necessary to slow the
communication down. This can be achieved
by choosing a slower baud rate from the list
provided.
If the programmer is still not detected,
please refer to the Installation
Troubleshooting Guide located in the
“On-Line” help.
