Introduction
Thank you for purchasing the 12G-CROSS HDMI / SDI 4K CROSS CONVERTER.
The 12G-CROSS is a truly portable converter, which incorporates our easy to use LCD and button control
system. This gives you easy access to most of the amazing features that have been unavailable without a
computer until now. The days of having to play with complicated dip switches or having to carry around a
computer to change a simple setting are gone.
The 12G-CROSS can be controlled using our USB Control panel available at
http://decimator.com/DOWNLOADS/DOWNLOADS.html
The 12G-CROSS features the following four modes:
1. HDMI to SDI while simultaneously converting SDI to HDMI
2. HDMI to HDMI while simultaneously converting SDI to SDI
3. HDMI to SDI and HDMI
4. SDI to SDI and HDMI
The 4K scaling engine can be driven by either the SDI or HDMI inputs, supports horizontal and/or vertical
flipping and can be locked to either the SDI, HDMI or Genlock inputs.
This unit also includes:
•Support for VESA formats via the HDMI input
•Support for 2K and 4K Format conversions on the output
•Support for both 3G level A and B on the input and output
•Horizontal and/or Vertical image flipping via the scaler
