FAQ & Support
General FAQ
- Will the device work in windows (XP,V,7,32bit and 64bit)? YES
-
- Response time? Electrically: 250 ms minimum recommended measurement for PnP, use stream mode on developer’s probe for ~12 samples / second. Thermal response time will vary depending on the selected probe and its thermal mass and the dissipation of the medium in which it is placed.
-
- Will this device work with a smart phone or PDA? Maybe if the device has a host A jack We have used the device with windows mobile 5 and 6 with a host USB or a compact flash to USB host adapter. This device has not yet been demonstrated operational with USB OTG and the mini AB plug on most dual purpose phone USB jacks.
-
- Is this device USB 2.0? The device is USB Full Speed which is USB 1.1, but USB 2.0 compatible. The bandwidth requirements of sending characters for a temperature measurement don’t require
-
- What is the longest cable length I can get? We have successfully built and accurately tested a device with 130’ of cable between the usb connector and the probe.
-
- Are these devices susceptible to EMI? If the wire between the USB plug and the probe are shielded and twisted, the effect will be minimized, but the effects are field dependent. Give us a call.
-
- Is there a minimum order? If the probe is not part number we stock, then there is a minimum.

Communication: Plug and Play FAQ
- Can I talk to this device with my own software / integrate this device in my own system? (YES if plugged into a USB host jack. Visit the download section to get the API and some example code to get started.
-
- Will this device work in Labview? NO, not like the developer’s device will. There is a process of "hijacking" the device with a custom driver in Labview, but installing that driver will remove the ability to have the probe interface with the DIRECTEMP°® Software. This driver can be removed and the probe functionality restored. Using the plug and play probe with labview is not currently supported and you are on your own if you attempt it. If you get it to work reliably please let us know.
Communication: Developers FAQ
- How do I talk to this probe in Linux? Minicom. Device will show up as TTYACMX, where X is the 0 based number in the order it was plugged in.
-
- How do I talk to this probe in Mac? Use a terminal program and find the virtual serial port.
-
- Will the device work in older versions of Linux? The device does not enumerate properly in kernel 2.4 series without extra drivers. Most newer 2.6 kernel distros will enumerate the developer probe as a valid serial port.
-
- Is the developers probe a usb or serial device? The developer’s probe is a USB device that "acts" like a serial device and with communication through a serial port the software creates, but is not a physical plug
-
- Is the developers probe available for production? YES the developer’s probe name is simply a label.
-
- How does it work in Labview? Labview VISA serial server works with the device just as if it were a physical serial port.
-
- Does it work with labview in linux? We have not tried this, but if you can get labview to communicate with a TTY device, then it should work.
