Low Voltage Input Connection; Chassis Sync In; Control Expansion Connector; Communications Expansion Connector - Honeywell VideoBloX User Manual

Note that the chassis may alternatively be powered via the low voltage AC / DC
connector (see
input power supply and the low voltage supply, to ensure continuous system operation in
the event of failure of one of the power sources.

Low Voltage Input Connection

This may be connected to a low voltage supply of 18-24 VAC or 18 to 24 VDC. This
power input is
connector.
Note that the chassis may alternatively be powered via the main input power connector
(see Main Input Power
supply and the low voltage supply, to ensure continuous system operation in the event of
failure of one of the power sources.

Chassis Sync In

Optionally connect the master video synchronization source to this BNC connector. This
allows all video switching to take place during the vertical sync of the master video
source.
Note that video switching may also be synchronized to the main input or the sync signal
on the "Control" connector.
Please refer to the
on configuration / diagnostics relating to the sync input.

Control Expansion Connector

This connector allows for connection of control signals between multiple VideoBloX
chassis. The pin-out of this connector is automatically modified depending on
configuration for the chassis being a master or slave.
Generally, this connector may be wired pin to pin between one master and multiple slave
chassis.

Communications Expansion Connector

This connector allows for connection of serial communications signals between multiple
VideoBloX chassis.
WARNING: The main input power supply must be used in
conjunction with an uninterruptible power supply (UPS) rated
greater than 400 VA and is CE certified for system reliability.
The UPS is not provided by Honeywell and is the responsibility
of the installer.
