3.4. Environmental considerations
This symbol indicates that this equipment must be deposited at a collection
point for proper waste treatment once it has reached the end of its useful
life.
3.5. Interconnection
The AVD0001C01 includes the following types of connections:
- Power supply.
- Signal.
3.5.1. Power supply connection
The equipment is supplied with a suitable wall power supply. This power supply can
provide power to a single AVD0001C01. It is possible to connect several devices to the
same power supply as long as it is able to supply the necessary current. Read the
following information carefully before connecting the AVD0001C01 to a power supply
other than the one delivered with the equipment.
The AVD0001C01 power supply is connected via a 2.5mm jack and the voltage must
be between 5 and 15 VDC. The equipment contains an internal switched mode
regulator that allows this wide range of input voltages without reducing energy
efficiency. Power consumption depends on the voltage supplied.
The power supply's negative terminal is connected to the outer ring of the connector
and the metal case of the equipment, while the positive terminal is the connector's
center pole.
If the AVD0001C01 is powered by DC voltage from a vehicle, protection is required for
the common transients (cold crank, load dump, etc) as the equipment has no internal
protections for these events.
3.5.2. Analog video connections
All electrical analog video connections are BNC type. The following suggestions should
be keep in mind when wiring the electrical signals.
All coaxial cable used must be Belden 1694A or similar. This type provides the greatest
lengths because it is used to calculate the equalizers in the AVD0001C01. Cables
carrying signal between the module and the devices should use single piece
construction, avoiding spliced sections with double BNC female or barrel connectors.
If it is necessary to split the cable into two sections the same type of wire should be
used in both sections.
