Input Processing

The wideband serial SD or HD signal enters the module from rear BNC J10
(labeled In) to an input amplifier. It is then equalized for the specified cable
lengths in the equalizer circuit.

Microprocessor

The main functions of the microprocessor include:

Providing remote control and monitoring capability for the module
(through ethernet),

Communicating with equalizer IC to monitor signal present status,

Relaying module status through on-board LEDs, and

Configuring module components at power up.
