Wall Mounted Equipment Touch — The Equipment Touch is
a wall mounted interface used to connect to the RTU Open to
access the control information, read sensor values, and mainte-
nance. This is an accessory interface that does not come with
the RTU Open controller. Wire the Equipment Touch interface
to the RTU Open’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 infor-
mation. See Appendix A of the Equipment Touch Installation
and Setup Guide for navigation and screen content.
Field Assistant —
Field Assistant is a computer program in-
cluded with the purchase of the Tech Tool Kit (USB-TKIT).
This is a field Tech Tool to set-up, service, or download appli-
cation 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 simi-
lar and functions the same as i-Vu
®
Open controller. See
RTU Open Troubleshooting —
Troubleshooting is accom-
plished by viewing the communication LEDs. The LEDs indi-
cate 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 31 and Fig 77.
