1)
Close SJ6 and let SJ7–SJ18 open for +5V main supply, close SJ7–SJ18 and let SP6 open for +3.3V main supply.
To prevent electric damages never close SJ6 and SJ7-SJ18 at the same time.
Presence of +3.3V supply at the used slot connector is signalized by Indicator LED D1 (yellow LED).
2)
Open SJ19- 26 for access to the /OE- and LE- signals from additional electrical circuits.
