ATU Port Expander

Starting at: $29.95

The ATU Port Expander is a device that attaches to a Multus Basic or Proficio transceiver’s ATU port, interprets band data sent to it and selects a corresponding output port for the activation of relays (or other devices) such as a low pass filter relay(s). It also provides a separate output port for the activation of a two port remote antenna switch such as the MFJ-4712 (via a bias tee). Each output port is capable of sinking 350ma and has a maximum input voltage of 50V. The ATU Port Expander is well suited for driving inductive loads (relays).

Features:
*Compatible with ATU port of the Basic and Proficio transceivers.
*Six output ports (50V maximum voltage, 350ma per port).
*Separate antenna switch port.
*Port selection configuration via selection jumpers.


The ATU Port Expander is sold as a kit and contains SMT devices. A bare bones option is available that provides the PCB, programmed microprocessor and socket. A bill of material is available on our support forum.
