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.
Field Assistant:
Field Assistant is a computer program
included with the purchase of the Tech Tool Kit
(USB-TKIT). This is a field Tech Tool to set-up, service, or
download application software to the RTU Open controller
and includes a USB Link Cable. The link cable connects a
USB port to the J12 local access port. See Fig. 60.

Communication LEDs:
The LEDs indicate if the
controller is speaking to the devices on the network. The
LEDs should reflect communication traffic based on the
baud rate set. The higher the baud rate the more solid the
LEDs will appear. See Table 23.
NOTE
: Refer to the RTU Open Multi--Protocol Controller
Controls, Start--Up, Operation and Troubleshooting manual.
Contact your Bryant applications engineer for details on
configuration and troubleshooting of connected networks.
