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 AISG3.0 protocol at the

same time. The AISG ports of the module share the same configuration information and have

the same serial number.

There are 2 motors inside MIRCU-S24, which can drive 8-frequency antenna currently. In

near future, with the increase complexity of antenna demand, the firmware will be updated to

supported up to 20-frequency antenna, expected to be done by Q2 2021.

The 2 pairs of AISG ports have no difference on function but authority. Any band can be

assigned by AISG port no matter AISG 1 or 2, provided the band is not yet configured by

another AISG port.

The device serial numbers that can be read by ASIG2.0 base station by scanning the MIRCU-

S24 module are as follows: (default access permission)

When the device access permission for the port is shown as “No Access”, the AISG2.0 base

station will not be able to scan the device. The access permission of the port is set by MALD

configuration command as defined in AISG3.0 protocol.

For example, the module has 8 devices and the device access permissions are set as below:
