Failed Benchtop test

[rhoads2234]

I have searched both in CD and on FIRST Forums.

We tethered the cRIO and the DS together and when we enable the DS with the dongle, the lights on the victors still flash as if they have no signal or it is disabled.

We have triple checked all connections on the Electrical and Driver stations. Any ideas on the problem? and a solution to it?
We are using victors instead of Jaguars, could this be the problem?

Thank you in advance

I had this same problem helping a different team. Everything was wired correctly but I had forgotten to switch it from Auto to Tele....

Just wondering, does the motors turn when you push the joystick forward? The lights will always flash if there is currently no data going through the victor/jaguar, but they should turn to a solid red or green light when you move the joystick.

We set ours up w/ victors and it works. You just need to know a bit more than the directions state when you do wifi.

You might simply not have completely inserted the male end of the PWM cable into the Victor's connector. It isn't obvious to an inexperienced set of fingers whether the connection is made properly. Try reseating the connector, aiming for it to go a few more millimeters deeper than it was the first time.

It might help to use a strong light to look into the Victor's PWM connector and get a good idea of exactly where the pins need to go.

A good thought, but unfornutely, it doesn't work when the joysticks are pushed forward (or back.)

Also it is in Teleop, and We have tried reseating the PWMs.

You would also see the light not come on if you don't have the dongle attached and the DS set to enable mode.

The dongle is in and it is set to enabled.
We are baffled by the problem.
Should we try to re-image the cRIO?

No don't think you're suppose to re-image the cRIO or update the driver station Firmware until after you have completed testing the hardware portion (what you are trying to do now), according to the benchtest manual.

Are you sure you have the wiring in the correct direction? I believe the white wire on the PWM cable should face the inside of the digital side card and on the Victor the white wire should face towards the outside edge. Also make sure you have the digital side card plugged into the cRio via the digital expansion module closest to the network ports.

Yeah, we've checked all our connections on the cRIO and the electrical board. So far, nothing has changed...

It seems one of the problems is that we can't see the cRIO on the laptop. We've connected the cRIO to the laptop with an Ethernet crossover. Although the laptop can see that something is plugged in, it cannot establish connectivity with the cRIO so we can't image it. We think this is the same problem as the DS being unable to enable to the cRIO...any thoughts?

I'll have Brian from 103 respond to this, if he's unable to figure it out, how far are you from their area?

does your digital sidecar have power? when we first set up ours we forgot to power it, without the digital sidecar being powered it cant recieve the signal from the module and can't sent out a pwm signal.

Yes the digital sidecar has power, all three lights(5V,6V and the one that says BAT) come on. Every other indicator that the board has that is mentioned in the Benchtop test documentation comes on.

We think there may be something wrong with cRIO. We have tried using other crossover cables to see if the cable itself was the problem, but it still won't connect to anything.

Crossover cable? You should only use that to connect the camera to the cRIO's second ethernet port. All the other ethernet cables you use should be standard straight-through connections.
