Vi-Q4/C3 User Manual Viq602c

1 Overview

 The Vi-Q4C3 is a quad video processor that accepts analogue video from up to four cameras or

other video sources and combines them on a single video output.

 Each video input image can contribute to the composite real-time image on the analogue video

output.

 The image from each input channel can be individually scaled, cropped, mirrored and positioned.

 Menus allow the user to configure the unit

 Configuration may also uploaded and downloaded using a PC

 The Vi-Q4/C3 has fully user-programmable screen formats

 The Vi-Q4/C3 can be gen-locked from another The Vi-Q4/C3

 The Vi-Q4/C3 has features specifically aimed at rail transport applications including special

circuitry to monitor performance, alarm relays for reporting error conditions, rugged build standard
for hostile environments.

 Video presence is displayed on front-panel LEDs and loss of video can trigger alarm relays (per

channel) if required.

 Freeze detection hardware, that is independent of the main video processing path, monitors the

system to ensure frozen or swapped imaged cannot be displayed should a malfunction occur
within the unit.

 If polled RS485 communication is used, an alarm is invoked if communication is lost.

 Watchdog timers monitor the correct operation of the main processor and other hardware.

 Software updates may be installed via either the front-panel or rear-panel RS485 ports.
