Inputs
The yellow LED is on when the External Trigger forces a current flow
through the EXT TRIG+ and EXT TRIG- pins.
This input is optocoupled and can be driven by both an NPN or PNP type
command. The connections are indicated in the following diagrams:

For DS1100, the general purpose input IN1 is used in the Standard
Application Program to store the code verifier (see “Store Verifier HW” in the
WinHost Help On Line). Use the input connections indicated in the figure
below. For DS2200, this input is not used.
