The opto outputs are under software control and may be used to drive electronics that
may be used for start lights. The opto outputs are connected to the transistor in the opto
coupler, the + is connected to the collector and the – to the emitter of the transistor.
Maximum allowed current through the transistor is 10mA.
The AMBrc decoder is equipped with a USB interface which is for future use, but it can
currently be used to get power from a connected (laptop) computer. In that case you may
also use the 12VDC power input for backup power.
The AMBrc decoder receives the signal of each passing transponder and combines the
transponder number with the exact passing time. The decoder sends the information to a
computer on which (AMB) timing software is running.
An easy check on proper operation of each passing transponder is done with help of a
headphone, since every transponder passing generates a “beep” signal.
At power-up the AMBrc decoder will beep 3 times and gives AMB20 compatible output
to support AMB20 software. AMBrc software will trigger the AMBrc decoder for AMBrc
output.
