The RTU Open controller can be set to communicate on
four different protocols: BACnet, Modbus, N2, and
LonWorks. Switch 3 (SW3) on the board is used to set
protocol and baud rate. Switches 1 and 2 (SW1 and SW2)
are used to set the board’s network address. See Fig. 72
and 73 for protocol switch settings and address switches.
The third party connection to the RTU Open controller is
through plug J19. See Fig. 74 for wiring.
NOTE
: Power must be cycled after changing the SW1--3
switch settings.
Refer to the
RTU Open v3 Integration Guide
for more
detailed information on protocols, third party wiring, and
networking.

Interface
The Equipment Touch interface is a wall mounted interface
used to connect to the RTU Open controller to access the
control information, read sensor values, and perform
maintenance. This is an accessory interface that does not
come with the RTU Open controller. Wire the Equipment
Touch interface to the RTU Open controller J13 local access
port. There are 2 password protected levels in the display
(User and Admin). See the Equipment Touch Installation
and Setup Guide for more information. See Appendix A in
the guide for navigation and screen content.
