First use
See the image below for connection details.
Set the aspect select jumper to the desired position (default 4 aspect).
Connect a 12 Volt regulated power supply to the power terminals. Each board requires up to
150 mA. If using multiple signal controllers a minimum 2 Amp power supply is
recommended.
Connect signal and feather LEDs to the appropriate terminals. Ensure your LEDs have
suitable resistors installed for 12 Volt operation.
Apply power and observe all LEDs illuminate for a quick self-test.
Press the test button (on board) to trigger danger.
Timer operation
There are two basic states of operation, timer and normal.
The AutoSignal can be used with built in timers to simulate further blocks at the end of scenic
sections and should be used by the last AutoSignal in a chain.
The LED near the aspect selection jumpers indicates state. If it is flashing then normal mode is
selected. If it is on without a flash then timer mode is selected.
Timer mode should be used at the end of chains only, i.e. the last signal in a connected chain to
simulate further blocks. Only one AutoSignal in a chain should be set to timer mode.
Take care when removing jumpers not to short out or bridge any other jumpers.
