Protocol Interface Translator (PIT)
Honeywell Video offers the technology
for a truly integrated system, and the PIT
is the versatile device providing this
capability. It lets you choose the equipment
that is appropriate for your installation
without restriction. As well as providing
control for all Honeywell Video products,
high-speed domes, VCRs and multiplexers,
the PIT also converts VideoBloX protocol
to that of other manufacturers, allowing
for retrofit installation to third party
equipment. Simple DIP switch configuration
selects a variety of protocols.
Hardware versions of the PIT are:
HVBPIT44: Converts RS422 VideoBloX
protocol to RS422 Output protocol for
control of other equipment such as
high-speed domes.
HVBPIT43: Converts RS422 VideoBloX
protocol to RS232 output protocol for control
of other equipment such as VCRs,
multiplexers and DVRs.
AVBPIT4i3: Provides an extension of the
HVBPIT43, offering integral optical isolation
on the RS232 output.
Alarm Input/Output
Expansion Modules
I2C Alarm Input/Output expansion
modules provide both flexibility and
expandability. The I2C modules allow
system users to increase the capacity of
the VideoBloX system to 256 Alarm
Inputs and 256 Control Outputs. The
modules attach directly to the VideoBloX
CPU using a single RJ11 style connector.
The modules can also be remotely
installed by connecting them to a PIT
configured in Alarm Concentrator mode.
The modules may even be connected to
a satellite matrix switch allowing for
additional inputs and outputs.
HVB12C16I: Capacity for 16 potential
free (dry) Inputs.
HVBI2C16O: Capacity for 16 FET
Outputs for low-power devices (LEDs).
HVBI2C16KB: Provides a remote
keyboard with 16 user keys and
16 LEDs. This device can be used
wherever remote control and monitoring
is required. Pressing a key would trigger
a Sequence thus, for instance, switching
a video signal, recalling a preset or
unlocking a door.
Data Port Expander
Honeywell Video’s range of Data Port
Expanders simplify expanding a system
without sacrificing reliability or response time.
The RS422 Data Port Expander expands a
single VideoBloX RS422 channel into multiple
RS422 channels. This provides system
installers with the ability to implement larger
systems using simple directly connected
cables. The Data Port Expander also acts
as a Repeater – by cascading the units
communications is extended from the typical
4000 foot (1200 metre) RS422 specification
to far greater distances. The multiple ports
each support 32 devices.
HVB422C4: Is a simple four-channel
expander.
The 8 and 16 channel versions provide
additional features:
• Rack mounted
• Automatically detects certain fault
conditions
• Isolates those channels with fault
conditions
• Status LEDs
• High-capacity power supply – each
channel individually protected
HVB422FT8: Is an eight-channel expander.
HVB422FT16: Is a 16-channel expander.
Pan/Tilt/Zoom
Telemetry Receivers
Connects pan/tilt equipment and
motorised zoom lenses to VideoBloX,
allowing for remote control of PTZ
equipment via a simple serial interface.
The receiver drives external equipment
such as lights, washers, wipers and
electric locks using auxiliary outputs.
Preset positioning is standard for
equipment with feedback potentiometers.
VBPTZDC: Telemetry Receiver with DC
output.
Microphone Receiver
A balanced receiver for eight microphones
– allowing microphone modules to be
remotely located. The balanced
transmission system allows the
transmission of the audio signal with
minimal interference. Each channel has
adjustable gain, as well as indications for
signal present and overload. A headset
may be connected for audio monitoring
and adjustment and phantom powering
to the microphones simplifies installation.
HVBPZM8R: Microphone receiver,
balanced, for eight-channel.
Surveillance Microphones
Consists of a pressure zone microphone
and an audio preamplifier/balanced
transmitter. The unit has adjustable gain
as well as indications for signal present
and overload. The microphone can be
mounted within the transmitter or can
be remotely located on an extension lead.
HVBPZMMIC: Pressure Zone Microphone.
Data Converter
The HVB232i485 unit converts RS232
data to RS422 data and additionally
provides isolation between the
communication lines. This allows for
extending RS232 links and conversion
of the signals as required. Changeover
switches can configure the RS422
as a master or slave port, while the
RS232 may be switched to allow direct
connection to a PC or to the RS232 port
of VideoBloX products.
HVB232i485: Communications
converter – optically isolated.
