Is the instrument plugged in and switched on at the wall / socket?
If using batteries, are they fully charged?
Is the instrument connected to the computer? (check that all cables are fully inserted into sockets)
Is the instrument in “PC Mode”? (CR-4xx series)
Is the instrument switched on?
Is your Spectramagic NX HASP key (USB dongle) plugged into the computer?
Has your Spectramagic NX software acknowledged that it has “found protect key”?
After opening your Spectramagic NX software, have you opened a file in which to work? (an existing one or a new one)
If you have been using a trial version of the Spectramagic NX software, has the trial period expired?
Connection failed: Retry after after changing communication setup
This is an “IT” issue
On your computer, search for the “Device Manager”
On the list of items, look for “Ports”
There will be an item that either identifies your instrument e.g. “spectrophotometer” or the conversion cable that is used to connect your device (as this is what your computer sees) e.g. “USB serial converter”
If there is nothing notable, right click the ports that are visible and click “scan for new hardware”
Note the number of the COM port that your device is connected to
In Spectramagic NX, click the “Instrument” tab
Select “Communication set up” and the “Serial Port Settings” menu will appear
Select the drop-down menu to show the COM ports that are available and select the one that you noted in Device Manager
Click on the blue “Connect” icon
This will turn into the pink “disconnect” icon ready for when you are finished and wish to disconnect the instrument
If you still do not succeed please contact your IT department
