Solution
The number of transceiver modes on all RS-485 ports are limited by the operating system of the Controller. All RS-435 ports are capable of the following 4 transceiver modes, except ports on Linux RT controllers: 2 Wire Auto, 2 Wire DTR, 2 Wire DTR Echo, and 4 Wire. The Linux RT controllers are capable of 2 Wire Auto and 4 Wire only. You can determine your controller's operating system by opening the controller's System Settings tab in
NI MAX.
See your hardware manual for further information on the supported wire modes.
