You can change its TX power, working channel through com tool. RM900A is a high Tx-power, high sensitivity IEEE 802.15.4/ZigBee module. Based on a combination of Atmel’s latest MCU wireless hardware platform, power amplifier and low noise amplifier, the RM900A offers superior radio performance. The module contains Atmel’s AT91SAM7X256 Microcontroller, AT86RF212B RF transceiver, balun, two RF switches, power amplifier and low noise amplifier. The balun transforms the differential radio transceiver RF signals (RFP/RFN) to a single ended RF signal. The RF switches separate between receive and transmit path. These switches are controlled by the RX/TX indicator. During receive the RF signal, switch will send it to the low noise amplifier. The signal will be amplified by the low noise amplifier and fed to the radio transceiver AT86RF212B using the second RX/TX switch and balun. During transmit, the AT86RF212B’s TX signal is amplified using a power amplifier, and then fed to the antenna via the RF switch. 3.1 Modem Characteristics 3.1.1 Electric Characteristics Test conditions (unless otherwise stated), Vcc=3V, Tamb=25°C Parameters Supply Voltage (Vcc) Current Consumption: RX mode Range 3 to 3.6 40 Unit mA Condition Current Consumption: TX mode Current Consumption: Sleep mode 170 mA 600 uA TX: Mid 3.1.2 RF Characteristics Parameters Frequency Band Number of Channel Channel Spacing Transmitter Output Power Receiver Sensitivity On-Air Data Rate Range Unit 868-868.6/910-924 1/10 +20(max) -105 40(@915MHz) 20(@868MHz) Tx output/Rx input Nominal Impedence 3.2 Pin Configuration 50 Condition MHz MHz dBm dBm kbps Ω BPSK modulation DSSS Pin Description Pin Description DGND DGND nRESET DGND TXD1 TXD0 RXD1 RXD0 GPIO0 10 RTS/LED2 11 GPIO1 12 CTS/LED3 13 GPIO2 14 GPIO/LED4 15 GPIO3 16 GPIO/LED5 17 TEMP_E/GPIO4 18 GPIO/PS_CS 19 WakeUp/GPIO5 20 GPIO/PS_FRAME 21 BUZZER/GPIO6 22 +3.3V 23 GPIO7/PS_DIR 24 AGND 25 BUTTON0/GPIO8 26 AREF 27 BUTTON1/GPIO9 28 DIO1/AD1 29 GPIO10 30 DIO0/AD0 31 SPI_MISO 32 JTCK 33 SPI_MOSI 34 JTMS 35 SPI_SCK 36 JTDO 37 SPI_SEL 38 JTDI 39 +3.3V 40 +3.3V 3.3 Physical Characteristics Parameters Range Size Operation Temmperature Range Operation Relative Humidity Range 46×26×7 -40 to +55 Unit Condition mm ℃ No more than 80% 3.4 Antenna Reference • Suggest antenna:868MHz/910~924MHz antenna • MMCX connector on board, need a RF cable to antenna, such as MMCX to SMA RF cable. • Reserved UFL connector on board. 3.5 Label Caution: This device complies with Part 15 of the FCC Rules / Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. MPE Reminding To satisfy FCC / IC RF exposure requirements, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. Les antennes installées doivent être situées de facon à ce que la population ne puisse y être exposée à une distance de moin de 20 cm. Installer les antennes de facon à ce que le personnel ne puisse approcher à 20 cm ou moins de la position centrale de l’ antenne. La FCC des éltats-unis stipule que cet appareil doit être en tout temps éloigné d’au moins 20 cm des personnes pendant son functionnement. Information for the OEM Integrators This device is intended for OEM integrators only. Please see the full grant of equipment document for restrictions. Ce dispositif est destiné aux équipementiers et intégrateurs. S'il vous plaît voir la pleine subvention du document de l'équipement pour les restrictions. Label Information to the End User by the OEM or Integrators If the FCC ID of this module is not visible when it is installed inside another device, then the outside of the device into which the module is installed must be label with “Contains FCC ID: SU3RM900A-01 and Contains IC: 20969-RM900A”. Si l'ID FCC de ce module est pas visible quand il est installé dans un autre appareil, puis l'extérieur du dispositif dans lequel le module est installé doit être étiquette avec"Contient FCC ID: SU3RM900A-01 et Contient IC: 20969-RM900A".
