the behavior of the cRIO is no green light??

[yara92]

the behavior of the cRIO is no green light suddenly. NO power on.
It works perfect from January 2009 up today.
I have 24[V] by measuring the to ends of the wire which connected your 24V power supply to the power distribution board and the connected your cRIO to the 24V cRIO power supply terminal on the power distribution board.
What is wrong.

[yara92]

I found the problem a loose wire between the cRIO and the PDB

Also, change your battery and make sure it's fully charged.
It will measure 24v, but not have enough umph to power up the cRIO.

thank you
this is vary important thing, we done it, First

Hi Mark
we have another problem at the classmate there is 0.0 volt see pic

[Mark McLeod]

The voltage reading originates at the Analog Breakout on the cRIO's first module.
To get it to work, there are two typical reasons for the 0.0v:

• The Analog Breakout needs a jumper on the outer two pins
• The Analog Breakout needs to be receiving power directly from the Power Distribution Panel

is there any docoments related to read who to do that, it will be nice frome you to send me the linke

This year's is in the Chapter 3 of the Control system Manual, starting on page 11.

We have a jumper on the outer two pins also the analog breakout is receiving power from power distribution bored
Still we get the same problem I'm not sure why??

[Mark McLeod]

If the jumper is installed and the power LED is lit on the Analog Breakout installed in cRIO slot 1, then that should be all you need.

• Double-check that you have the correct cRIO Module labeled "NI 9201," the Analog Breakout will fit on the Solenoid Module, but won't operate properly of course.

• I assume you have code running and confirmed via the Driver Station status.

• Pull the Analog Module from slot 1 of the cRIO and look carefully underneath to see if any of the pins in the cRIO connector are bent.

• You should have received two Analog Breakouts and two cRIO Analog Modules NI 9201. Try swapping Modules and Analog Breakouts.

My programmer girls solve the problem:
1. The battery have 3 [v] for the Cypress IO board. They change the battery, then it works. But had some conflict.
2. They Double-check that for the correct cRIO Module labeled "NI 9201," , it was in wrong place. They change it.
3. after 4 hours we lost the volt 3 [v] instead 9 [v] from the battery. Interesting thing, but they drive the Robot.
4. If we can drive the robot low volt Cypress IO board.
I will consider if you cane send me any link about the Cypress IO board who he works and what is his job

[Mark McLeod]

The Cypress IO board is optional.
It can be used to add switches and LED displays of your own design to the Driver Station.

• Switches need two wires: signal (white) to P4_4 & ground (black) to ground. The power wire (red) is unused.
• Pots use all three wires: signal, ground, & power (note: full range of pot will be read by your code as 0 to 3.3)

It can also be added to the robot if you can think of a useful purpose for it.
