Update 10 suggests putting a switch in series with the power of the IR sensor board. Unfortunately this is a hassle in that you have to remember the process of turning the robot on, then turning the IR board on, and the reverse order for shutting everything down.
Instead of using that we decided to hook it up to a Spike Relay. Hook the 12V and GND up as normal and then hook the power of the IR sensor to M+ (or M-, or both if you’re using two IR sensors). Then the ground of the IR sensors goes to ground on a breaker panel. Using this you must turn on the IR sensor using the program as follows in the chart below.
So if you connect the IR sensor power to M+ you would set the relay output fwd to 1 in order to power the board, 0 to shut it off. Remember though that your board will only work when the robot is enabled now.
Fwd(Wht) Rev(Red) M+ M- Indicator Solenoid Function
0 0 GND GND Orange Both Solenoids OFF (default)
1 0 +12v GND Green Solenoid connected to M+ is ON
0 1 GND +12v Red Solenoid connected to M- is ON
1 1 +12v +12v Off Both Solenoids ON
For those of us which it is too late since ours is already fried, in the Team Update 10 it is stated:
“If you have reason to believe that your PIC code has been corrupted, and you have the capability program PICs, you can use the code that Mr. Grieb has graciously provided.”
Has anyone found the code posted anywhere?! Even if a team is able to flash the PIC, that is not too helpful unless the code actually becomes available.
