6 Troubleshooting
Cause and countermeasure is explained if abnormal operation or function of RZ-EC6 is found.

Phenomenon
Communication to a device isdisable.

Cause and Countermeasure
・ Check that the connection between the PC and CHINO product ismade properly.
・ Check that driver of RZ-EC6 is installed correctly.
・ Check the COM port number set to the PC.

PC does not recognize RZ-EC6. ・ If USB hub or USB extension cable is in use, it is rare but PC can notrecognize RZ-EC6. Connect RZ-EC6 to USB port of the PC directly.
・ It may take sometimes for PC to recognize RZ-EC6 after theconnection. Check COM port from device manager after a fewminutes.
・ RZ-EC6 does not operate on a driver of CHINO engineering cable(RZ-EC4 or RZ-EC5). Install specific driver from attached CD-ROM.
Unable to install to a PC.

・ If installation is failed, start again from procedure (1) of "3. Installationof driver".

When problems are not improved after executing troubleshooting above, contact the dealer(instrumentation, installation or sales agent) or nearest CHINO’s sales agent.

If repairing is necessary, contact the dealer or nearest CHINO's

Warning sales office. Only the service engineers appointed by our company
