Typical Applications

The ZRB4 was designed to be powered from the same voltage that a thermostat or doorbell system operates from, 24VAC or 24VDC. Refer to the Specifications section for more detailed power requirements. The serial communications port on the ZRB4 is capable of full-duplex and half-duplex operations, depending on firmware loaded into the ZRB4. The ZRB4 can interface with a host of RS485 based protocols such as BACnet, Modbus and other proprietary protocols based on the firmware image programmed into the device. Commands and data can originate from either the wired or wireless sides of the ZRB4. When operating as a full-duplex device the Rx and Tx pairs are connected to the corresponding pair on the communicating device. When operating in half-duplex mode the positive pair and negative pair are attached together to the corresponding connection on the communicating device. The ZRB4 uses the IEEE 802.15.4 protocol (2.4GHz ISM band) to communicate wirelessly. There are two LEDs on the bottom of the ZRB4 which indicate network status and unit status. The pushbutton is used to leave and join wireless networks. When joined to a wireless network with an Energy Manager the ZRB4 becomes one part of a multifaceted system designed to eliminate wasted energy and increase operating efficiency. When paired with another ZRB4 to replace a wire the communications channel requires no special personnel for installation thereby saving money and time.

6.1 Network Mode

6.2 LED and Pushbutton Switch Functions

| Network Mode
---|---
LED1
(blinking)| Red – Node is searching for a network
Amber – Node has joined a network and is waiting for permission to stay from network coordinator. Green – Node has joined a network and has received permission to stay from network coordinator.
LED2| Not Used.
SW1| Note: The state/color of the LED will change to indicate a Short or Long press.
Short Press – Press and hold SW1 until the LED color has changed state once and release immediately. This will start network search mode. Long
Press – Press and hold  SW1 until the LED color has changed state twice and release immediately. This causes the node to leave the current network and look for a network using the extended pan id “Autani” to join.
