Network Management Control Bus

The H2TU-C provides a Network Management Control Bus on pin 46 of the card-edge connector. This allows the
various ADC Management System protocols to manage the H2TU-C through the HMU-319 HiGain Management
Unit. Whenever the H2TU-C is under management, the MNGD message displays periodically on the front-panel
display.
Some H2TU-C-231 List 1E features are affected when it is under management. Consult the
management unit practice for further information (see
