AS-CVTPROx00-1 Zone Bus/N2 Bus Interface Converter
Application
The AS-CVTPROx00-1 Zone Bus/N2 Interface
Converter is portable converter designed to provide a
communication interface between the room sensors
and controllers operating on a Zone Bus or N2 Bus
and a Personal Computer (PC) or specified models of
the Palm
TM
family of Personal Digital Assistants
(PDAs). See Table 2 for compatible Palm devices. See
Table 4 for compatible tools, Operating Systems (OSs)
and controllers.
Note: The AS-CVTPROx00-1 converter can be used
in place of the MM-CVT101-0 converter module. The
MM-CVT101-0 converter is not compatible with
Windows NT®, Windows® 2000 and later versions of
Windows OSs.

Connecting the CVTPRO Converter to a Controller
with N2 Screw Terminals
To connect the CVTPRO converter to a controller with
screw terminals (Figure 6):
1. Disconnect the three N2 wires from the controller
screw terminals and temporarily isolate the
individual bare wires with insulating tape.
2. Remove the 4-pin N2 socket from the CVTPRO
N2 cable to expose the three wires (Figure 6 and
Figure 7).
3. Connect the exposed N2+ (blue), N2- (white), and
Ref (red) wires from the CVTPRO N2 cable to the
controller screw terminals. Observe proper
polarity.
4. Connect the 6-pin RJ11 phone plug on the
opposite end of the CVTPRO N2 cable to the
CVTPRO converter (Figure 3 and Figure 5).
CVTPRO N2 Cable
3-Pin N2 Plug
To scan a N2 Bus:
1 Disconnect the N2 Bus from the N2 master
controller.
2 Remove the N2 plug (with attached N2 wires) from
the controller (4-pin plug on the VMA and 3-pin
plug on other controllers).
3 Connect the 3-pin or 4-pin N2 plug that was
disconnected from the controller in Step 2, to the
4-pin N2 socket on the CVTPRO converter cable.
(See Figure 7.) Observe proper polarity (N2+ is
blue, N2- is white, Ref is red).
4 Connect the 6-pin RJ11 phone plug on the
opposite end of the CVTPRO N2 cable to the
CVTPRO converter (Figure 3 and Figure 5).

Connecting the CVTPRO Converter to a Controller with a N2 Jack
To connect the CVTPRO converter to a controller with
a removable N2 plug:
1. Remove the 3 or 4-pin N2 plug from the controller.
2. Plug the 3-pin plug CVTPRO N2 cable into the
jack on the controller (The Variable Air Volume
Modular Assembly [VMA] has 4-pin jack, and other
N2 controllers have 3-pin jacks). Observe proper
polarity (N2+ is blue, N2- is white, Ref is red).
3. Connect the 6-pin RJ11 phone plug on the
opposite end of the CVTPRO N2 cable to the
CVTPRO converter (Figure 3).
Note: Figure 7 shows the possible connections with
a VMA controller with a removable 4-pin N2 plug.

Compatibility
Table 4 lists compatible tools, Operating Systems, and
controllers used over the Zone Bus and N2 Bus with
the CVTPRO converter.
Compatible controllers include the Air Handling Unit
(AHU), Unitary Controller (UNT), Variable Air Volume
Controller (VAV), Network Dialer Module (NDM),
and VMA.

Note: The CVTPRO converter is not compatible with Zone Terminal Units (ZTUs). For ZTUs, use the CBLPRO-2
converter. See the Auxiliary Gear Technical Bulletin (LIT-6363080) for details on Johnson Controls® converters.
1 For proper CVTPRO converter operation when running on Windows NT OSs, Service Pack 6 must be installed.
2 For proper CVTPRO converter operation when running on Windows 2000 OSs, use the Professional Edition only, and
Service Pack 2 must be installed.
3 On Zone Bus applications running on Windows 2000 OSs, HVAC PRO Version 8.04B or later must also be installed.
* When using the VMA14x0 with HVAC PRO software (versions prior to Version 8.04B only) over the Zone Bus with
Windows NT OSs, a Device Conflict box appears whenever the user attempts an operation (for example, upload or
download). To bypass the box, select Yes or No and the box disappears. The selected operation continues as
expected.

Battery Power Recommendations
The CVTPRO converter requires two (user-supplied)
AAA alkaline type batteries on N2 Bus applications
(when the External Power Adapter is not used).
Battery life varies depending on the N2 Bus load,
ambient temperature and type of batteries. See
Table 5 and observe the following guidelines.
• Always have a spare set of new batteries on hand.
• When performing long downloads with the
CVTPRO converter, use the External Power
Adapter instead of batteries.
