■ External Connections
RS-485 Connection
Note: 1. If RS-485 is selected as the communications method (i.e.,
Connecting an RS-232C or USB Master Device to an RS-422/485 Slave Device
First set the same communications conditions (baud rate, stop bits, data length, and parity) for the master device, the Interface Converter, and
slave devices.
Note: 1. 1-to-N connection via OMRON NT Link communications is not supported.
Connecting a USB Master Device to an RS-232C Slave Device
First set the same communications conditions (baud rate, stop bits, data length, and parity) for the master device, the Interface Converter, and
slave devices.
Note: There is no isolation between the USB and RS-232C sides.
