907-HDM2
DUAL HIGH DEFINITION VIDEO MULTIPLEXER
/907-HDM2Multiplexer_prod_banner_narrow.jpg)
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

- 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
- Simplifies troubleshooting with advanced diagnostics
- Maximum jitter margin available for cabling
