500ACO2-HD/SD

Dual HD/SD-SDI Digital Auto Signal 2x1 Changeover

The 500ACO2-HD/SD dual HD/SD Autochangeover is designed to provide extension to the 5600ACO for HD or SD SDI, DVB-ASI, SMPTE 310M, AES audio, bi-level/tri-level syncs and NTSC/PAL video. The unit can also be operated as a standalone changeover unit with two independent 2X1 switchers. The 500ACO uses latching relays to ensure maximum reliability and minimal disruption in the event of any failure.

The 500ACO2-HD/SD is housed in the 500FR Frame that will hold up to 16 modules.

Features

Auto detection of six signal types Five modes of operation (including VistaLINK®) Auto changeover - two standalone auto changeovers or two link changeovers Manual DIP switch control - two independently controlled 2x1 switchers GPI Control - two independently GPI controlled 2x1 switchers ACO Extension - slave unit of the 5600ACO (requires 5600ACO firmware version 1.2 or higher)

Support for VistaLINK® monitoring and control Fully hot-swappable from front of frame with no BNC disconnect required Tally output on Frame Status bus upon loss of input signal for quality monitoring Latching relays maintain the current path on loss of power VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 500FR frame with 500FC VistaLINK® Frame Controller
