The figure below shows another basic test arrangement, with the daughterboard
installed for negative pulse operation and zero input bias on the LED:
In the above drawing, an HCPL-2601 current-drive opto-coupler is installed on the
daughterboard, and the daughterboard is configured to drive the opto-coupler input with
zero current (by jumpering pins 2 and 3 to GND1). The daughterboard is positioned as
far as possible to the socket lever in order to connect the daughterboard to the negative
pulse circuitry.
