1. DESCRIPTION
The V6155 is a Dual SDI Distribution Amplifier which operates at both HD and SD data rates. Due to
limitations on the rear panel one amplifier has 4 outputs, while the second has 3 outputs. Each amplifier
automatically detects the input signal as SD or HD, and has a reclocker. The reclocker in each amplifier
may be independently switched OFF using on-board links.
The V6155 is a part of the V1600 range of interface modules and is built on a 3U high Eurocard which is
fitted into the V1606 3U Chassis. The V1606 can have a total of up to 14 modules from the range. A
suitable passive rear module, such as the V16HR3F, is required. The amplifier receives all its power and
control from the rear module.
Each amplifier independently detects and adapts to either HD or SD automatically. Front panel LEDs
indicate whether each amplifier has an input, and its standard – HD or SD. When operating SD the
amplifiers will accept ASI signals, but only some of the outputs will be valid. (All outputs actually carry data,
but the non-valid ones have inverted polarity.)
The DART remote monitoring and control system will indicate unit type, signal present and standard (HD or
SD) and whether either reclocker is disabled.
