2.3 Setup of GXE
When connecting plural GXEs to the system, each GXE must have a unique slave ID.
Before installing into the system, set each GXE so that the slave ID does not overlap.
To do setup, you can connect PC and GXE one to one with RS-485 line and execute our communication tool on PC.
Refer to the communication GUI guide for installation and operation method of communication tool.
Prepare USB ⇔ RS-485 converter for PC. It can be used as long as it is an RS-485 converter
compatible with half duplex communication and automatic transmission control.
The USB ⇔ RS-485 converter we confirmed the operation is "USB-003 made by Human Data Ltd."
Refer to the instruction manual for information of connector / cable wire diameter etc. used for connection.
・Connection
When connecting, be sure to connect 1)CN84 ⇒ 2)USB cable in order.
After completing the connection of the communication line, apply input voltage.
Do not perform operations such as disconnection of the communication line and attachment / detachment
of the connector while apply input and communication tool is running.
Even if the input is cut off, there is a possibility that electric charge may remain at the output terminal.
Be careful when removing the communication line.
