Page 6: Introduction
Introduction EpiSensor’s ZMB Wireless Modbus Interface is designed to make it easy to collect data from a wide range of heating, cooling and other energy meters using the Modbus RTU (over RS-485) wired communications standard. The ZMB reports data through the wireless sensor network to the Gateway, which then manages bi-directional communications to various compatible software and IoT platforms. -
Page 7: Alt Led
Check the power supply, and if the problem persists, contact EpiSensor support. Alt LED The Alt LED will flash when data is transmitted or received on the ZigBee wireless network. For mains powered nodes, it will always be active - but for battery powered nodes, it will only be active when in Command Mode. -
Page 8: Install Mode
Send a DATA message to the Gateway for any enabled sensors that are not reporting in ‘snap-to-clock’ mode. Leave the current network. Mains powered Nodes will automatically try and join a new network once they have left and will periodically retry the join. Battery powered nodes will go to sleep. Start “Install Mode”. -

Installation should only be carried out only by personnel qualified in the installation of electrical equipment. All parts of the circuit within the enclosure must be considered to be at dangerously high mains voltage when the unit is connected to a mains voltage source. Mechanical This section describes how to wall-mount the ZMB enclosure, the enclosure materials and important safety considerations when connecting the ZMB to external systems. -

ZMB has been isolated from any high voltage supplies. Please consult the safety notes at the start of this user guide for more information. Important Safety Note EpiSensor equipment should be installed, operated, serviced and maintained only by qualified personnel. There are no user-serviceable parts inside the ZMB enclosure, and it should always be isolated from mains voltages before opening the enclosure lid. -

The label material is gloss white PVC foil with permanent adhesive and gloss overlaminate. The following table lists the certification and safety symbols that appear on the certification labels of EpiSensor products. Please refer to it for a definition of each symbol. -
Page 12: Communications
Communications There are a variety of communication options on the ZMB that are used to configure settings, stream live sensor data and poll 3rd party systems for data. This section describes the communications capability of the ZMB, with information on wiring, configuration and safety considerations. Modbus communications are possible from the ZMB using an RS485 multidrop network or an RS232 point to point cable running at TTL levels (3.3Volts). -

the greater the attenuation. Because attenuation increases with frequency, cables also exhibit a lowpass filter behavior so that achievable distance diminishes with data rate. The communications parameters are configured using the Gateway UI or the API. Because Modbus is the only protocol implemented on the RS485 network, and Modbus always uses 8 data bits, the number of databits are not configurable. - Page 14 communications parameters - those being the Baud Rate, Parity and Stop Bits. All Modbus devices must use 8 databits (if it is configurable).

Note: Error codes from Modbus are detected by the ZMB but are currently not reported to the Gateway. Wireless Communications All EpiSensor products use IEEE 802.15.4 ZigBee Pro for wireless communications operating at 2.4GHz. This is a secure, scalable mesh networking communications protocol designed for transmitting small amounts of data reliably, and at low power levels. -
