Local Access
BACview
6
Handheld
The BACview
6
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. 53. This is
an accessory interface that does not come with the MP
controller and can only be used at the unit. Connect the
BACview
6
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. Contact your Bryant applications engineer for details
on 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--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.
