Modbus USB(RS232) to High Powered Wireless System Gateway


Modbus USB(RS232) to High Powered Wireless System gateway in Wall Mounting Enclosure with Antenna, 12/24Vdc Supply (External Plug-Top PSU Included)

The Gateway Modbus USB is part of the family of 4-noks wireless ZigBee devices. Its purpose is to be an interface between a Personal Computer and the network of 4-noks ZigBee devices using an universal standard protocol such as Modbus/RTU via USB port. The use of Modbus protocol guarantees an immediate use of many commercials SCADA for PCs.

The device is supplied directly from the USB port. Its role in the ZigBee network is Coordinator: i.e. it forms an active part in creating the network and maintaining wireless traffic from and to other similar devices. Furthermore it can function as “parent” device for battery sensors of the same family and saves data that they asynchronously send regardless of Modbus requests.

If connected with the bridge ZR-BR-485-EM, this gateway offers a full transparent Modbus channel.

In wall mounting enclosure with antenna, 12/24Vdc supply (external plug-top PSU included)

Delivery in approximately 2-5 working days (subject to availability)
