50BVJ and 50BVW Controls
This section is for 50BV units with VAV controls (50BVJ and
50BVW). The VAV controls will include an I/O Flex 6126 con-
troller with an I/O Flex Ex8160 Expander module.
The hand-held BACview or Virtual BACview is used to access
the 6126 controller. These devices are used to view current unit
conditions and change parameters.
NOTE: The handheld BACView was obsoleted in 2019 and is no
longer available for purchase. Existing handhelds are still compat-
ible with the 50BV control interface currently available for pur-
chase.
The hand-held BACview connects to the Rnet port on the 6126
controller. The hand-held BACview uses a fixed screen with 4
lines. Due to the limited screen view, the user will need to scroll up
and down to view data and make any configuration changes. Fig-
ure 33 illustrates a typical hand-held BACview.

CAUTION
This unit uses a microprocessor control system. Do not short or
jumper between terminations on circuit boards or modules;
control or board failure may result.
Be aware of electrostatic discharge (static electricity) when
handling or making contact with circuit boards or module con-
nections. Always touch a chassis (grounded) part to dissipate
body electrostatic charge before working inside control center.
Use extreme care when handling tools near boards and when
connecting or disconnecting terminal plugs. Circuit boards can
easily be damaged. Always hold boards by the edges and avoid
touching components and connections.
This equipment uses, and can radiate, radio frequency energy.
If not installed and used in accordance with the instruction
manual, it may cause interference to radio communications. It
has been tested and found to comply with the limits for a Class
A computing device pursuant to International Standard in
North America EN61000-2/3 which are designed to provide
reasonable protection against such interference when operated
in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the
user, at his own expense, will be required to take whatever
measures may be required to correct the interference.
Always store and transport replacement or defective boards in
an anti-static shipping bag.
