The Acumesh Wireless RS485 connects any device with a RS485 port to form a point to multi-point mesh network. It is ideal for buildings and systems that monitor energy flow, industrial automation and campus facilities. AcuMesh transceiver eliminates the usual wires in a RS485 installation by using a flexible and simple wireless communication solution.

Accuenergy manufactures 2 transceiver models: the AcuMesh-K transceiver (standalone transceiver, including 2db whip antenna and power supply and the AMX-Mesh Transceiver Module- with an AcuMesh module that plugs in Acuvim II series meter directly, including a magnetic mount 2 db antenna with 3-meter extension cable.
