VREF Error
Hello all,
First of all, I'm very happy to see this online community, We have been needing an IQAN development/troubleshooting/idea-sharing place for a while, and I'm happy to be a part of it,
My question is:
What exactly does a "VREF Error" message mean when it is not associated with an input channel? We have a MD3 connected to 2 XA2 modules. Intermittently, a system message will display that reads: "XA2.0 VREF Error 2.2V"
The system runs on 24VDC.
What conditions could possibly cause the VREF on an XA2 module to dip so low? Again, the VREF error is not indicated as being associated with any particular input -- just an XA2 module. If the system/battery voltage drops low, does the reference voltage regulator have trouble maintaining 5 volts? Wouldn't the system just shut off before that happens?
Has anyone experienced this before?
Thanks!

Diode suppression on XC21, 22, 23 outputs?
We are looking at energising automotive relays using the outputs on either the XC21, 22 or 23. Do we have to use relays that have diode suppression in parallel to reduce the risk of shortening the life of the output?

XA2 Module used at -57 deg C
Has anyone used an XA2 or other module at -57 deg C or a temperature below the catalogued -40 C and had success?

Is the XT2 being phased out? If so, is it going to be replaced with another expansion module that can handle 2 seperate CAN lines?

Availability of a high amperage expansion module?
Are there any plans to add a high amperage output module to the IQAN platform? Currently, we use the J1939 functionality to control Pran Systems PR3510 modules (15 Amp per output) for lights, wiper motors, and other high current loads but it would make things much less complicated if we could control everything from within one software application.
