Phidgets Forums

On a Windows 10 machine:

Yesterday one of our technicians upgraded the firmware on a DC1000_0 and it no longer functions via the javascript interface. This is the error that comes up:

Connection error: missing channel parent:0x1c

I have reinstalled both the Phidget libraries/CP and the application but get the same error. We even swapped the computer and it has the same issue.

What else can we do?

Hi,

Probably the JavaScript library itself is out of date. Are you using JavaScript in-browser or from Node?

One thing to check is whether you can control the DCC1000 from the JavaScript control panel that ships with the network server.

Thank you.

It is a NodeJS application...we can control it from the browser. If it's "out of date" then that means the new firmware is not compatible with the phidget22@2.6.14?

1) How do I rollback to the firmware that works with our software?

2) Is there to enforce a particular, known-compatible, firmware version?

You can either upgrade the phidget22 JavaScript library to v2.8.0+, plus the Phidget Network Server to version 1.8+, or you can use the phidget22admin tool to roll back the firmware.

The Control Panel will always offer to upgrade firmware to the latest version.
