7707CVDRA-A4

Analog Video, 4-Channel Audio and RS-232 / 422 Fiber Receiver

Product ManualManual
  • VistaLINK® enabled

The 7707CVDRA-A4 is a VistaLINK® - capable composite analog video, 4-channel audio and bi-directional RS-232/422 fiber optic receiver for broadcast quality video signals.

The 7707CVDRA-A4 is backwards compatible with previous 7707CVR-A4 versions.

The 7707CVDRA-A4 is ideal for analog VTR link extension or camera PTZ applications.

The 7707CVDRA-A4 occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

Features
  • Single card fiber optic receiver for analog video, four analog audio and bi-directional RS-232/422 signals
  • Supports both NTSC and PAL video signals
  • Broadcast quality analog video and audio performance
  • 2 bi-directional RS-232 or 1 bi-directional RS-422
  • Superior digital data transmission
  • Signal transport over fiber uninterrupted by loss of input video, audio or data feeds
  • Adjustable gain, DC offset, and pre-emphasis for up to 300m of Belden 1694A coaxial cable
  • Fully hot-swappable from front of frame with no fiber disconnect/reconnect required
  • Comprehensive signal and card status monitoring via four digit card edge display or remotely through SNMP and VistaLINK®
  • VistaLINK® capable for remote monitoring via SNMP (using VistaLINK® PRO) when installed in 7800FR frame with a 7800FC VistaLINK® Frame Controller
  • Optical output wavelengths of 1310nm, 1550nm and up to sixteen CWDM wavelengths (ITU-T G.694.2 compliant)
  • DWDM wavelengths (ITU-T G.694.1 compliant) also available
