MIRCU tilting angle with adjustment accuracy of ± 0.1 °. 5 RET System and Working Principle 5.
MIRCU User Manual shifter in an antenna, and thus able to control antenna electrical tilt angle. While maintaining real time communication between MIRCU and PCU (Portable Control Unit), PCU send control command to MIRCU; MIRCU will return the control result to PCU, and PCU act as Human-Machines interface. 5.3 2 Primaries Working Principle The MIRCU-S24 module has 2 pairs of AISG ports and supports AISG3.0 protocol, and can be controlled by 2 primaries (Base Stations) which meet AISG2.0 or AISG3.

MIRCU User Manual Note 2) 1 primary can operate the command successfully, but the command sent by another primary failed to achieve. √：Note 1) MIRCU-S24 can operate the commands from 2 respective primaries simultaneously, and comply with AISG standard. Note 2) ‘When “RESETALD” is run on 2nd primary when 1st primary is performing an action, all the action on the 1st primary will be suspended. a) Scan MIRCU-S24 supports 2 primaries to scan MIRCU simultaneously.
MIRCU User Manual MIRCU-S24 does NOT support 2 primaries to set tilt simultaneously. When 1st primary is setting tilt, the 2nd primary is able to scan, reset port, reset ALD but NOT able to calibrate, set tilt, upload/download file, configure MALD and ping.
MIRCU User Manual The file download command starts with ‘DownloadStart’ and ends with ‘DownloadEnd’. The file is carried and downloaded by using ‘DownloadFile’ command. The supported file types are FirmwareFile and ConfigureFile. The module does not support multiports file download operation simultaneously, which mean when 1st primary is performing download, the 2nd primary ports will be close and no operation can be performed.
