2.3 USB-to-RS485 connection

OJ-DRHX PC-Tool is connected by means of a USB cable to a USB-to-RS485 converter and

subsequently to Modbus connector “B” on the OJ-DRHX (ﬁg. 1).

A converter for USB -> Modbus RS485 communication must be used, e.g. type CNV-USB-RS485I

or USB-RS485-WE-1800-BT.

Follow the steps below:

• Consult the OJ-DRHX instructions for information on opening the front cover to access the

Modbus connector.

• Comply with the OJ-DRHXsafety instructions while working on the unit.

• Connect the Modbus cable to either the RJ12 “B” connector or to the spring terminals marked

“A”, “B” and “GND”.

• Connect the Modbus cable to the USB-to-RS485 converter.

• Connect the USB cable to the USB-to-RS485 converter.

• Connect the USB cable to a USB port on the PC.

• Connect the supply power to the OJ-DRHX.

• Start the OJ DRHX PC-Tool.

The connection is a point-to-point connection (PC to drive)

• Provides access to all connected drives in a network by changing the Modbus ID

• Prevents active Modbus communication from other devices (PC-Tool is the only master on the

Modbus)

When using USB-RS485-WE-1800-BT

• Modbus A: Orange wire

• Modbus B: Yellow wire

• Modbus GND: Black wire

Note

When connecting the OJ DRHX to the PC via a USB cable, the PC USB port may become damaged.

• Do NOT use a PC power cable with ground plug when the PC is connected to the drive.
