Few Questions regarding IR board

Hi,
my team managed to connect the IR board to a 9 Volt power supply with the 2 positive wires and the 2 ground (negative) wires.
We trained a remote control too. Now we only need to connect the IR board to the 4 digital inputs on the RC.
According to the manual there are 4 wires, each one for a digital input. We found those wires.
And there are 2 other (last white and black) wires witch don't connect to anything.
My question is: how do I do connect it to the digital port on the RC? With a PWM cable? If with a PWM cable so how do I connect 1 wire to it and where (there are 3 legs on the PWM cable)?
We tried connecting the wire to the signal leg on the RC on the digital ports, but when we tested it on the on-line terminal (in EasyC pro) it didn't recognize the digital port.

Another question:
Will the robot be controlled only in some range (the IR receiver range)?
If the robot turns 180 degrees it means I can't control it no more?

Thanks in advance.
Team 2217

Re: Few Questions regarding IR board

You can effectively wire the outputs to two PWM cables.

The first should have the (+) Positive and the (-) Negative voltage, and the signal output of output 1 going to the white signal cable. Plug that PWM into one of the outputs. then wire the other outputs to the other PWM cable. Plug that cable in sideways on the signal line.

Re: Few Questions regarding IR board

Ok I understood that.
But there are 2 power cables and 2 ground cables. Should I connect every 2 cables to 1 leg on the PWM?
And another thing: the digital I/O gives only 5 volts. The IR board needs at least 7, no?

Re: Few Questions regarding IR board

Yes, you are right in that it needs at least 7 volts. We are going to connect the power to a breaker (12V), and then connect outputs 0,1,2 to a PWM plug and three to another plug. The pwm plugs will be plugged in sideways so that all pins are on the "SIG" row of the digital inputs. (The row closests to the words "DIGITAL IN/OUT"
