RS-485 Interface Specificity
NOTE: All the pins of the RS-422 default interface should be used for operation.
The RTS line must be switched each time the driver is sent and received. There is no automatic
switch back. This cannot be configured in Windows.
The voltage drop caused by long line lengths can lead to greater potential differences between bus
stations, which can hinder communication. You can improve the communication by running a
ground wire with the other wires.
NOTE: When using RS-422/485 communication with PLCs, you may need to reduce the
transmission speed and increase the TX Wait time.
Device Manager and Hardware Installation
Install the driver before you install the interface module into the Slim Panel. The driver installation
media is included with the package. After the interface module is installed, you can verify whether
it is properly installed on your system through the Device Manager.
CAUTION
