This manual is produced for users of the ZcoRE3-2400 OEM wireless transceiver module from REnex Technology Limited. It covers the operating principles and capabilities of the ZcoRE3-2400 module.
While using for ZcoRE3(20)-2400, precaution below is necessary: PRECAUTION 1. The installed antenna must not be located in a manner that allows exposure of the general population at a distance of less than 4cm. 2. Mount the antenna in a manner that prevents any personnel from entering the area within 4cm from the central position of the antenna. 3. It is recommended that the installer place radio frequency hazard warnings signs on the barrier that prevents access to the antenna. 4.

ZcoRE3-2400_User_Manual_V1.0 3. Module Interface The module interface includes the power input (3.3 V), power output (3.3 V), configuration button signal, serial ports (CMOS 3.3 V), A/D, I2C, test signal, JTAG and digital I/O, etc. These are integrated on a dual row, 20 pins per row, 1.27 mm pitch connector (J1). Refer to Table 3.1 for a detailed pin definition.
ZcoRE3-2400_User_Manual_V1.0 The pin definition of the header interface is shown on Table 3.1; the input and output description is based on module side. The main serial port is port 1 which includes TxD1 (pin 5) and RxD1 (pin 7). It will be set as the default port in the factory. There are three UART ports which can be used on the module. Pin 3 (RST) is the reset input; the module will reset if a low level signal is input.

ZcoRE3-2400_User_Manual_V1.0 3.2 RF Interface Different RF interfaces are provided on the ZcoRE3-2400 module. For the ZcoRE3-2400 module, only a chip antenna can be soldered on when the modem ship out. Refer to diagram below for detail information of chip antenna. For the ZcoRE3(20)-2400 module, only the external antenna is available. P1 (refer to mechanical drawing) is designed on PCB board for the reversed SMA antenna connection via a special RF cable.

The module contains RAEMESH application developed base on EmberZnet stack 2.
ZcoRE3-2400_User_Manual_V1.0 3.4 Wakeup If the radio is set to RFD mode, the Wakeup pin Pin19 is used to make the radio asleep and wakeup. A constant high on this pin will make the radio go to the sleep mode and a low level signal on this pin will wake-up the radio. The Radio sleep mode is the power save mode with very low power consumption. (<60uA) The Wakeup pin must be held up to 10ms before sending a data packet. 4.
When the sensor node sends data to gateway, the gateway will receive the data plus the last four digits of sensor node ID in the {}. When the gateway sends data to sensor node, the sensor node radio will only receive data in the {}. For RAEWATCH_RCS The data in the {} will be untouched by either gateway or sensor node. You get what you send. For RCS details, refer to: 904-E800-120 RAEWATCH WSN Communication Standard.
ZcoRE3-2400_User_Manual_V1.0 Base on correct setting and connection, you will see following display on your screen when power is applied.

The Length is 0x20 based. E.g. the total length of a packet without command data is 4, the Length byte is 0x20 + 4 = 0x24.
ZcoRE3-2400_User_Manual_V1.0 4. 5. 6. 7. Check the Network Status of the RFD before sending the data at the first time. Command: 5B24205D. It is recommend 1s interval between two data packets for RFD. Check [] for sending acknowledge in Unicast mode. There is no ACK for multicast mode. For RFD, if there is no network, the RCM will automatically wake up every 1 minute to search for a new network. It can be interrupted at any time. RCM will keep in asleep if it has joined a network.
