First Step - Install the USB Driver The SCR02 module uses the Microchip PIC18F14K50 to handle all the USB protocols.
Reconfiguration is achieved by first disconnecting the 12vdc supply and any connected sensor.
Relay 1 will operate when the Voltage on PL1 Pin2 is less than.25v.
If unchecked the relay will de-energise after both timer "Time On" and the trigger is removed.I will select "Range Min" for this noma example.Max DC load capacity, aC1, manual non inductive or slightly inductive loads 16A @ 250V AC, aC15.The SRF485 and SRF08 are used as instruction examples, but any listed sonar connects as easily.When the USB lead is connected normal operation of instruction the module is suspended and it enters configuration timer mode.It can be set to 0 if not required.Connections, pL1 Pin, sRF01, sRF02/08/10/235, noma sRF04/05, analogue 5 0v Ground 0v Ground 0v Ground 0v Ground 4 n/c manual Mode Mode n/c 3 Serial I/O SCL Trigger 0-5v (Relay 2) 2 n/c SDA Echo 0-5v (Relay 1) 1 5v 5v 5v 5v PL2 0v.We will document the procedure if and when there is a firmware update, but for now the links should be kept in this position.Right The configuration utility will load the current configuration from the SCR02.The 12vdc supply is not required during configuration as the USB 5v will supply the processor.There are two status LEDs.When the relay is de-energised, it will remain off for "Time Off" seconds before is can be re-triggered.
Operating Temperature -40C to 70C, lED indication.
I will manual set 1cm.
The SRC02 uses a 10-bit A/D to convert the 0-5v input to a number in the range 0-1023.
