BACview
6
Handheld:
The BACview
6
is a keypad/display
interface used to connect to the RTU Open to access the
control information, read sensor values, and test the RTU,
see Fig. 70. This is an accessory interface that does not
come with the RTU Open controller and can only be used
at the unit. Connect the BACview
6
to the RTU Open J12
local access port. There are 2 password protected levels in
the display (User and Admin). The user password is
defaulted to 0000 but can be changed. The Admin
password is 1111 and cannot be changed. There is a 10
minute auto logout if a screen is idle. See Form
48--50HCTQ--01T, Appendix A for navigation and screen
content.
Virtual BACview:
Virtual BACview is a freeware computer
program that functions as the BACview
6
Handheld. The
USB Link interface (USB--L) is required to connect a
computer to the RTU Open board. The link cable connects
a USB port to the J12 local access port. This program
functions and operates identical to the handheld.
RTU Open Troubleshooting —
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 10.
