VMA1400 Series Overview and Engineering Guidelines Technical Bulletin 15
CablePRO
CablePRO (AS-CBLPRO) is an interface device that is used between a
computer or Palm™ compatible handheld device and the VMA. Use
CablePRO for box balancing or commissioning via the Zone Bus
communication port on the room sensor.
When used with a VMA, the CablePRO is strictly an electrical
interface between the serial RS-232 port of the computer and the
VMA. CablePRO operates on 15 VDC drawn from a VMA and
provided through the Zone Bus. The data rate on both the RS-232 and
the Zone Bus is 1200 baud.
The VMA connects to the RS-232 COM port of the computer via a
DB9 or DB25 connector supplied with the CablePRO.
The diagnostic LEDs on the CablePRO indicate normal Zone Bus
communications. The LEDs flash only when the VMA is transmitting
or receiving data.
Refer to the Auxiliary Gear Technical Bulletin (LIT-6363080) for
more information on the CablePRO.
CVTPRO
CVTPRO (AS-CVTPROx00-x) is a Zone Bus/N2 Bus interface device
that is used between a computer or Palm compatible handheld device
and the VMA. Use CVTPRO for box balancing or commissioning via
the Zone Bus communication port.
When used with a VMA, the CVTPRO is strictly an electrical interface
between the serial RS-232 port of the Palm compatible handheld
device and the Zone Bus. CVTPRO operates on 15 VDC, drawn from
a VMA through the Zone Bus phone jack. The data rate on both the
RS-232 and the Zone Bus is 1200 baud.
Refer to the Auxiliary Gear Technical Bulletin (LIT-6363080) for
more information on the CVTPRO. For additional information on
installing the AS-CVTPRO300-1 and ASCVTPRO400-1, refer to the
AS-CVTPRO300-1 and AS-CVTPRO400-1 Zone Bus/N2 Bus Interface
Converters Installation Instructions (Part No. 24-10158-0).
