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.
