USB Engineering Cable

RZ-EC4

Introduction
Thank you for purchasing USB engineering cable 'RZ-EC4.'RZ-EC4 is a USB engineering cable used exclusively for our products. This cable is designed to connect theengineering port of our product to the USB port of Windows 10 / Windows 11 personal computers (alsomentioned as PC).
Using RZ-EC4 with the parameter programming software enables an easy parameter setup from theengineering port for a product without communications interface.
*Engineering cable is a cable dedicated for setting parameter of a device. Do not use it for data acquisition of thedevice or do not connect it to the device regularly.
Understand the cable properly and read this instruction manual beforehand in order to avoid any trouble.

Precautions for CHINO engineering cable users
・If the COM port number used by the other product is also set to this cable, it may cause COM port
error for the both cables.
・ When changing the COM port number after RZ-EC4 is installed on the PC, make sure to use
unused COM port number.
・ RZ-EC4 does not operate on driver of different type CHINO engineering cable (RZ-EC3, RZ-EC5or RZ-EC6). Install a driver dedicated for RZ-EC4 by attached CD-ROM.
Ifusing RZ-EC4 on a personal computers (also mentioned as PC) using CHINO engineering・cable (RZ-EC5 or RZ-EC6), do not set identical COM port number for both products. If bothproducts are set to identical COM port number, COM port error or communication error mayoccur.

Request－ For the persons doing instrumentation, installation and sales －Be sure to handover this instruction manual to the persons using the cable.

－ For the users of the cable －Preserve this instruction manual until you scrap the cable and write down the setting details.

Cause and countermeasure is explained if abnormal operation or function of RZ-EC4 is found.

Phenomenon
Communication with theproduct not established.

The personal computer does
not recognize the product.

The product can not beinstalled to the PC.

Cause and Countermeasure▪ Check device engineering port (communication port) is set to "ENG".
Refer to the section "2-4 Device setting and connection".
▪ Make sure that the connection between the PC and the CHINO productis made properly.
▪ Confirm that the driver of RZ-EC4 is installed correctly.
▪ Check the COM port number set on the PC.
▪ If an USB hub or USB extension cable is in use, it is rare but the PC cannot recognize the product. In that case, connect the product directly tothe USB port of the computer.
▪ It may take time for the PC to recognize RZ-EC4 after the product has
been connected. After a few minutes, check the COM port status fromthe device manager.
▪ RZ-EC4 does not operate on a driver of CHINO engineering cable(RZ-EC3, RZ-EC5 or RZ-EC6). Install specific driver from attached
CD-ROM.
▪ If installation is failed, start again from procedure (1) of "3. Installation ofdriver".

When problems are not improved after executing troubleshooting above, contact the dealer or your local
CHINO’s sales agent.
