STG154: WMBus (Wireless MBus) gateway, VDC power supply. MODBUS - OMS wireless gateway. WMBUS Repeater

STG series WMBus gateways can create a WMBus RF network and connect serial and/or ETH based devices with wireless MBus devices. All communications can be done over a radio frequency network based on the WMBus standard. STG series WMBus gateways can act as TCP to WMBus gateway as a TCP server, TCP to WMBus gateway as a TCP client, or serial to WMBus gateway all in one device. Typical applications: automatic meter reading, home - building - industrial automation, wireless sensors, telemetry...

 

REDZ Broadband Power Line (BPL) connection allows the device to communicate with a completely transparent TCP/IP standard over low voltage power lines and enables easy connection between TCP/IP based terminals without the use of additional cables

 

#### STG gateways from hardware version 2 can also function as simple WMBUS repeaters
