ChemWiz-ADK Series 4 FAQ
Can I plug a USB cable into the ChemWiz-ADK’s external USB drive port and connect to a computer?
No, the external USB drive allows you to a access all data that you have saved onto the ChemWiz-ADK’s tablet. This includes spectral data, screenshots, PDF reports and more.
Can I use a regular computer running SpectraWiz or any other program with my CgenWiz-ADK Series 4 device?
Yes, you can use VirtualHere, a USB-over-IP utility, to access the ChemWiz-ADK. You can download VirtualHere Download VirtualHere Win64 or other versions at https://virtualhere.com. Use your regular computer’s WiFi to login to the ChemWiz-ADK’s access point and launch virtual here. Don’t forget you must install SpectraWiz and related drivers on your computer in order for the computer to recognize the device. You will be able to run SpectraWiz and any customizable Windows program
as if you had the device connected directly to your USB port!
Sometimes it takes a minute or so to establish WiFi connection. Is this normal?
The ChemWiz-ADK Series 4 consists of an Android tablet and also a spectrometer server (right side power button). The spectrometer server must power up for about 1 minute before spectral data can stream to the android tablet. The spectrometer server requires minimum power to operate and can be left on during and in between measurements so the system WiFi connection doesn’t have to be continually established.
How can I get the newest version of the ChemWiz-ADK Pro Software?
We are continually updating our Pro software options for our handheld systems. Visit the Google Play store for the most recent versions and download and install directly on your ChemWiz-ADK device.
