Page 11: Installation
3.1. Initial inspection The AVD0001C01 is a desktop unit and does not require installation in a rack or similar housing. However, it has threaded fasteners for M4 screws at its base for attachment to a panel or other surfaces if necessary. -
Page 12: Attachment
The power supply's negative output is connected to the metal case. • The AVD0001C01 is designed to be operated indoors and should not be used outside. It should also not be used in explosive, corrosive or radioactive environments or in applications that could endanger the lives of people or animals. -
Page 13: Environmental Considerations
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. - Page 14 The AVD0001C01 provides a switch that connects a termination to the input without requiring a load to be connected to the loop-through output. The switch should be set to the position labeled 75 ohm.

Upper panel of the AVD0001C01 The upper panel contains two LEDs. POWER ON: Green. This LED lights up when the AVD0001C01 is connected to electrical power. 3G. White. This LED indicates that the detected format of the analog video... -
Page 16: Functional Description
LED lights up the the distributor can function even though it is not indicating the specific signal format. 4.2. Functional description The AVD0001C01 is composed of three blocks: a DC restorer, an equalizer and the output amplifiers that distribute the signal. The first two blocks are described in more detail in the following. -
Page 17: Dc Restorer
The equalizer is in charge of modifying the frequency response of the distributor to compensate for the attenuation incurred as the video signal is transported over coaxial cable to the input of the AVD0001C01. This is done only once, as the module has a single input. -
Page 18: Module Remote Control And Supervision
0 dB. Under normal conditions when the signal has not been attenuated by the cable the gain does not require adjustment as the equalizer operates at both low and high frequencies. 4.3. Module remote control and supervision The AVD0001C01 CANNOT be remotely controlled or supervised. -
