[1]The drive has a 2.2K ohm resistor in series with this LED driver. Tie the minus side of an external high- efficiency 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. Connect the minus side of the resistor/LED combination to this pin. Con- nect the plus side to +5V. This pin is connected in parallel with the signal of the same name in the inter- face connector (J1).

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