The module contains RAEMesh application and comply with the RAE System’s RCS protocol. The module also has built-in RAEMesh Module Command Interface(RMCI). This documentation is focused on the instruction on RMCI interface. The RMCI command interface allows customer to easily access to low level mesh functionality without pain to develop the firmware. The module can be configured to a GTW to hook up to a getaway or just a stand alone regular full function node or a Sleepy reduce function node. Make sure to configure the module to right mode before using. Quick Start UART Via the TXD1 and RXD1 pins the command interpreter can be accessed. The RCM can buffer up to 128 bytes of incoming data in a software FIFO buffer and uses XON/XOFF flow control. See the datasheet of the Atmel ATmega1281 for more information about the build-in UART. Connect Pin5 (TXD1) and Pin7 (RXD1) to the customer board. Use the following settings for serial port. RTR and STD: 19200bps, 8N1. GTW: 38400bps, 8N1. Data Packet RCM will transmit any data in the { }, all data in the {} will be transparently sent out without radio’s interpretation. The maximum data packet is 50 bytes including {}. The data in the {} can be any characters including ‘{‘ ‘}’ ’[‘ ’]’ . The interval between 2 data packets must be >200ms for RTR and GTW. The interval between 2 data packets must be >1s for STD. Wakeup If the radio is set to STD mode, the Wakeup pin Pin19 (PE7) is used to make the radio asleep and wakeup. A constant high on this pin will let 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 so the power consumption can be very low. (<40uA) The Wakeup pin must be held up to 10ms before sending a data packet. Power Ground: Pin1, Pin2 and Pin4. VCC: Pin39, Pin40. 3.0V or 3.3V Radio consumes less than 100mW in normal RX/TX mode. Radio consumes 600mW at TX and 100mW at RX for High power module Heartbeat Connect Pin12 to a LED for heartbeat indicator. Reset RST: Pin3 Active Low. Revision: Dec, 2011 PC communication Please has your serial port debug software installed on the PC. For example: sscom32.exe Microsoft Hyper Terminal is not recommended for this application because it is not good to send characters and commands in Hex. Base on correct setting and connection, you will see following display on your screen when power is applied. GTW:
