[1]The drive has a 1.2K ohm resistor in series with this LED driver. Tie the minus side of an external high-effi- ciency LED (i.e., 2ma) to this pin. Connect the plus side of the LED to +5V.

[2]An external current-limiting resistor is required when connecting an LED to this pin. The minus side of the resistor/LED combination is connected to this pin. Connect the plus side to +5V.

[3]Jumper storage location (across pins 2 and 4).
