I/O Ports Not Responding To The Ez Builder UI Servo Control

I have an ezb v4 that has been on the shelf for several years. (worked when last used). I was on the shelf too so we are both a little dusty so bare with me.
When I set up an I/O port in ez builder for a servo there is no signal present on the signal pins. I have a scope on them. If i go to the diagnostics page of the ezb's web server and hit the "center all servos" button the pins come to life. I think its something simple but ...?

from on of DJ posts

1) Did you disable the low voltage monitor? I'm guessing you must have because the "My battery is low" on 6v would have been annoying And the servos won't move at all with power below the threshold

2) What servos are you using at 6v? Depending on the servo, it might not be able to accept 6v and it's behaving strangely

3) Do you have a volt meter to ensure the voltage coming from the power supply is indeed 6v? If not, you can add the EZ-B Info control to see. Check here: https://synthiam.com/Software/Manual/EZ-B-v4-Info-16059

What servos are you using?

You can connect to the WIFI right?

if not re set the network on the ezb4 unit 

connect to the ezb network on your WIFI settings

make sure your battery is charged


I am trying all things, lol

I'm using a bench supply running 7.4 volts .
The servos are tower hobby... i think mg 995? generic at any rate.

Hey Steve - we can get you up and running ...

1) do you hear a startup chime when power is applied to the ezb?

2) do you hear a welcome message when the ezb is reset with the reset button?

3) do you hear the connection chime when ARC connects to the ezb?

4) did you select the port using the configuration button on the servo control that matches where the servo is connected?

5) did you set min and max values of the servo control in the configuration screen?
#13  
Yes to questions 1, 3, 4 and 5. I didn't pay attention when I reset it. I can try that tomorrow. If i access the web server diagnostics page I can play all of the chimes and messages there.

Okay - next questions

1) Are you connecting to the ezb on the index #0?

2) does the ezb repeat my battery is low
#15   — Edited
Yes, I just have the one ezb.
No its not giving me a low battery message.
#17  
Thanks DJ
My bench supply is a variable voltage/current unit . The ezb was drawing a little over 300 milliamps. 
I will dig into this tomorrow.

Here we are another day,

what was the latest on your situation?

I will generate a diagnostic log for Mr. Sures today. I've got some "honey dos" to get done first...before I can play:D

I understand that

From bad to worse... I reset the EZB and then put it back in client mode. Then I re-downloaded and reinstalled ARC. Now when I choose connect, I get a single chime and then the disconnect chimes. The debug window show the following;

Got it! You (Ezang) were right on with your comment about antivirus. I added exceptions to my antivirus and to my firewall but that wasn't good enough.
I completely uninstalled the dumb thing and we have controls!

You are welcome

One last thing:
remember, when ever you re-boot your computer, the fire-wall - anti virus will "reload again" - you will need to shut it off again

be well!
