BACview

Handheld: The BACview

is a keypad/display

interface used to connect to the RTU--MP to access the

control information, read sensor values, and test the RTU,

see Fig. 57. This is an accessory interface that does not

come with the MP controller and can only be used at the

unit. Connect the BACview

to the RTU--MP’s 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--50H--T--2T, Appendix A

for navigation and screen content.

Virtual BACview:

Virtual BACview is a freeware computer

program that functions as the BACview

Handheld. The

USB Link interface (USB--L) is required to connect a

computer to the RTU--MP board. The link cable connects

a USB port to the J12 local access port. This program

functions and operates identical to the handheld.

RTU--MP 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.
