WALL MOUNTED EQUIPMENT TOUCH INTER-
FACE — 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 maintenance.
This is an accessory interface that does not come with the RTU
Open controller. You wire the Equipment Touch interface to
the RTU Open controller's 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 in-
formation. See Appendix A for navigation and screen content.
FIELD ASSISTANT — Field Assistant is a computer pro-
gram 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. The Field Assistant's menu structure is
similar and functions the same as i-Vu
