This SW-3108 receives, equalizes, and reclocks*up to 8 SDI inputs, perfectly switches the desired input to
SDI equipped monitors or receivers. The switch supports both HD/SD-SDI bit rates, and the re-transmitted quality
is guaranteed. Through RS-232, IR remote, or front panel push button, the control of the SDI switch becomes
versatile and easier. SW-3108 offers the most convenient and cost effective means for swift switch and
duplication of high quality SDI in the market.
Features
z3G HD/SD-SDI Switch
zUp to 8 input & 4 re-timing SDI outputs*
zDual Color indication LED of 3G HD/SD of the output SDI
zAutomatic detection of the SDI Input
zSynchronizes input/output (switch after vertical sync)
zProvides the equalized and reclocked*transmission path up to 300m (1000ft) at SD-SDI , 150m (500ft) at
HD-SDI or 100m (500ft) at 3G HD-SDI
zMultiple control by RS-232, IR remote, and push button
