Designed for use with the 6800+™ modular core processing platform, the VSM6801+ SDI monitoring distribution amplifier (DA) combines the functions of an equalizing, reclocking serial DA and a 4:2:2 to NTSC/PAL converter on a single DA-sized card.
VSM6801+ modules can be controlled at the card-edge, or controlled and monitored via the CCS Navigator™ software application, HTTP Web browser (with QXFE series frames only), NUCLEUS™ hardware control panel or via third-party control applications using SNMP.
