The MDCU (Multiple Device Control Unit) is the electronic module thatallows the remote control of the electrical downtilt(RET) in Amphenol antennas with factory embedded motors. For amultiband antenna, whatever the number of theindependent variable tilt controls (usually one per band), only oneMDCU module is installed. It behaves as if separate RETControl units were fitted for each band of the antenna anddaisy-chained together.

Connector caps are required to weatherproof any control cable or RETunit connector that is left unconnected after installation.

RET Motor Assembly, AISG 2.0

• Electrically Controls the Antenna RF Tilt
• Low power Consumption @ Idle stage
• Supports AISG v2 Protocol Only
• AISG RS485 Male/Female Connector
• Supports Daisy chaining

This AISG compliant Teletilt RET actuator enables operators toremotely change the electricaldowntilt of an antenna.The ATM200-A20 is shipped in AISG 2.0 mode. In the field, theactuator can be set to AISG 1.1 or2.0 as needed.The actuator's absolute position sensor eliminates the need forcalibration, enhances precision andprevents dropped calls caused by calibration sweeps. Male and femaleAISG connectors facilitate daisychaining actuators. As many as 32 actuators can be attached to asingle control line.This actuator is equipped with a flashing LED, which indicates datatransfer and tilt movements. It comesin a weather resistant gasket-sealed container that has a drain holeto permit drainage of condensedmoisture.The ATM200-A20 actuator can be field fitted onto Andrew Teletiltremote electrical downtilt (RET)compatible antennas that are already in service or factory fittedbefore delivery to the field.The part number for antennas with a factory-fit ATM200-A20 actuatorends in -AxM, with x referring tothe number of the attached actuators (either -A1M or -A2M).
