Advice on an Unusual Top Slot Adaptor
Peter has loaned me the the Adaptor that he 'won' in the recent eBay auction. I'm interested to see if I can 'read' it with OPL. The images will show serial number SN 002, which begs the question 'how many?'
SWITCHED..
. .
INFORMATION
.
The switch is 'sprung' and returns when released
The LED lights when the switch is 'ON'
The adaptor takes its power from the Organiser and works if the Organiser is ON (Active Mode) or OFF (Standy Mode)
It doesn't boot any item on to the main menu, and there is no evidence that there is any code on the unit and nothing to store anything on.
. .
OBSERVATIONS
I found out what I could about the elements
The blue 'Trimpot' is a potentiometer (you can still buy them today) Manufactured by BOURNS
ICL8211 Programmable Voltage Detectors Intersil have the ICL 8211 marked as an Obsolete product with no recommended replacement
Description The Intersil ICL8211/8212 are micropower bipolar monolithic integrated circuits intended primarily for precise voltage detection and generation. These circuits consist of anaccurate voltage reference, a comparator and a pair of output buffer/drivers.
.
QUESTIONS
.
(1) Which Top Slot 'pin' provides the power?
(2) Given the PIN Assignment in the Comms Link manual - How do you identify each pin number?
(3) If I want to test it 'out of the Organiser' Is there any issues with me using a 9 volt battery and a bread board?
. .
I'll see how I get on with these questions before asking any more.
Sincerely and in good faith
Martin
