The UA846Z2 Frequency Manager for GLX-D Advanced connects up to six GLXD4R receivers, providing rock-solid RF performance through patented data communication. GLX-D Rack Mount Digital Wireless System channel count can be increased to 9 simultaneous systems in typical environments (11 under optimal conditions) with flexible antenna distribution options for multi-system applications.

  • Provides advanced frequency management to a linked receiver community for improved RF performance and increased channel count
  • Link multiple receivers via RF ports for traditional antenna distribution
  • Intelligent frequency management quickly identifies the best frequencies
  • Identifies and assigns optimal frequencies to receiver/transmitter pairs
  • In case of interference, automatically and seamlessly transitions to backup frequencies
  • Provides power to the GLXD4R receivers, eliminating need for power strips or multiple outlets
  • Globally‐unlicensed 2.4 GHz frequency band

Are there different transmitters?

No. There is only one series of transmitters. These can be used with GLX-D receivers (GLXD4 and GLXD6) as well as with GLX-D Advanced receivers (GLXD4R).

Can I use standard GLX-D Systems with the new GLX-D Advanced systems?

If you are not using the Frequency Manager, then the GLXD4R receiver operates similar to a GLXD4 receiver. In that case, follow the guidelines and best-practices for GLX-D.

If you are using the Frequency Manager, we recommend only one GLX-D standard system.

How many channels I can run with GLX-D Advanced?

In an environment with no other WiFi devices you can run up to 11 channels. Under typical conditions (one WiFi channel is active) you can run up to 9 channels. The more WiFi channels active in an environment, the lower the max. amount of channels. Please be sure to use frequency manager.

I have two channels of GLX-D Advanced. Is the Frequency Manager necessary?

No. When running two channels we recommend using the UA221-RSMA antenna splitter to split the incoming antenna signal to the two receivers

What are the main differences between GLX-D and GLX-D Advanced?

The GLX-D Advanced receiver is rack-mountable and features detachable antennas. This allows users to use directional antennas, helping to increase system stability in environments with other WiFi sources.

The GLX-D Advanced Frequency Manager creates a shared group of frequencies for all receivers to use and automatically assigns frequencies to each receiver. If interference occurs, the frequency manager assigns new frequencies without audible dropouts.

What is the difference between Group A and B?

Group A is optimized for low latency (4 ms), ideal for a channel count of 6 systems, maximum 9.

Group B has a higher stability and a higher latency (7,3 ms), ideal if you experience interference or need to run 9 to 11 systems.
