AISG Cable of Connecting for 8 Pin Port Connection Jumper Control DB9 Male Female

What is AISG?
The Antenna Interface Standards Group (AISG) creates and maintains standards for the control and monitoring interface between a base station and a variety of tower-top equipment. These include antennas with remote electrical tilt (RET), tower mounted amplifiers and a variety of sensors that are used to monitor the operation of tower-top equipment. These are referred to as subunits. A complete list of those currently supported can be found here.
The standards include alternative PHY layers, an RS-485 bus and an OOK system using an MF radio-frequency signal transmitted within the coaxial cables joining antennas, amplifiers and base stations.
The latest version of the standards (v3.0) provides for devices with multiple control ports that may each be connected to different controllers (usually base stations), as well as the ability for the controller to map the RF system interconnections between devices connected to the bus. The standard comprises the base standard together with standards for each subunit type.
