[1]

The drive has a 2.2K ohm resistor in series with this LED driver.
Connect 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. The minus side of the resistor/LED combination is
connected to this pin. Connect the plus side to +5V. This pin con-
nects in parallel with the signal of the same name in the J1 interface
connector.
