Dual High Definition Video Multiplexer 907-HDM2 High Definition Video Multiplexer

The 907-HDM2 is an expandable High Definition (HD) Video Multiplexer that provides transmission of up to two HD-SDI camera signals along with four on-board serial channels (RS-232/485) for camera controls (e.g. pan and tilt) and sensors. Dual HD inputs on the remote card support connection of two HD-SDI cameras with either one channel at full 4:2:2 sampling and the other sub-sampled at 2:1:1, or both channels sampled at 4:1:1. The 4:2:2 channel can be selected via diagnostic software.

The 907-HDM2 can be used as a standalone card or stacked with a wide range of 907 expansion cards available in a variety of formats, including RS-232/485/422, TTL, Ethernet, CAN Bus, analog sonar, hydrophone, audio, and Tritech ARCNET. It may also be optically integrated into a larger 907 system via CWDM modules. Optical power budgets are typically 20-26 dB over 10 km of singlemode fiber. Enhanced diagnostics are supplied by on-board LEDs and through a dedicated Ethernet link when used with a diagnostics card (907-DIAG-E) and corresponding graphical user interface (GUI) software.

Features

  • Dual HD inputs include cable equalization and reclocking to improve recovery of low level or distorted input signals
  • Regenerated HD-SDI outputs to minimize jitter
  • Interchangeable SFP transceiver
  • 4x on-board bidirectional serial channels (RS-232 or RS-485)
  • Compatible with 907-DIAG-E diagnostic card and Graphical User Interface (GUI) software
  • Rugged design for harsh environments
  • Supports up to six 907 expansion cards

Benefits

  • Reduces cost and size for systems with need for combined data and HD video
  • Supports a wide range of optical options, including CWDM wavelengths
