MOD090-LP User’s Manual Technical Summary The MOD090 module allows you to build your own extreme-range, non-line-ofsight, point-to-multipoint wireless solution. The module uses the new technology in our 900Mhz and is fully FCC/IC certified for quick integration with no RF retesting required. The MOD090 solution offers the ideal combination of the maximum allowed transmit power and unbeatable interference immunity in conjunction with high throughput and validated encryption.
User’s Manual MOD090-LP Module Physical Interface RF Antenna MMCX RF Section Module SPI Interfaces Serial Peripheral Interface (SPI) is a full duplex synchronus serial interface that allows data to be shifted in and out of the AvaLAN Baseband Processor (MOD090-LP) 8 bits at a time, most significant bit first.

User’s Manual MOD090-LP SPI0 - LEDs and DIP Switches SPI0 is a master mode SPI that sends out 4 bytes per transaction. The first two bytes are alignment bytes and the last two contain the LED data on MOSI0, and the DIP switch data on MISO0. The first alignment byte is 0x55, and the second is 0xAA. These two bytes are used to determine the start of the transaction (0x55) and the start of the data (0xAA).
MOD090-LP User’s Manual TX_ACT: Indicates when data traffic is queued up for transmission across the RF. TX_ACT will be set for 32ms when data is queued up for transmission. RFQ5..0: Indicates the quality of the RF link. The lowest quality is only b0 set, the highest quality is reached when b5 is set. DIPs: A bit that is set in this byte indicates that the corresponding DIP switch is on. Byte3 b7 b6 b5 b4 b3 b2 b1 b0 DCH5 DCH4 DCH3 DCH2 DCH1 DCH0 MODE - DCH5..

User’s Manual MOD090-LP RFState: When set this bit indicates that the RF is currently connected. Radio: Indicates what mode the radio is in, when set it is in active mode. When clear the RF is in standby mode. CH3..0: Indicates what channel the RF is currently using. The setStatus command is used to place the module in standby mode/normal operation and to set the RF into manual channel mode by assigning a specific channel.
MOD090-LP User’s Manual Network Key Command The Network Key is A 32-bit number used for Network Identification. AvaLAN mseries devices with different Network Keys will not be able to communicate with each other. The Network Key can be changed without resetting the device. The getNetworkKey command will read back the last 32-bit key issued to the device. The setNetworkKey command stores a new 32-bit key to be used for RF communications.

MOD090-LP User’s Manual part and ranges from 0 to 100. BER7..0 is the 2-digit fractional part and ranges from 0 to 99. The block error rate is calculated over the last 1000 data blocks. Version Command The getVersion command is used to determine the firmware version running in the MOD090-LP.
User’s Manual MOD090-LP channel information back from the MOD090-LP. The host microcontroller must delay while the MOD090-LP completes the scan before reading any data. In SPI mode, the MOD090-LP will use the Data Ready line (pin 9) to indicate when the scan is complete and the data is available. In UART mode, the host microcontroller needs to issue the command and wait for data to be returned.

User’s Manual MOD090-LP OFS is the 16-bit integer Index value for this data point. The range of this index is 0 to (128 − Frequency Step Size). For example, with a step size of 1, the maximum value of OFS is 127, but with a step size of 8, the maximum value is 120. PEAK is an 8-bit integer representing the peak power detected at each frequency. AVG is an 8-bit integer representing the average power detected at each frequency.
MOD090-LP User’s Manual The getPacket command is used to read received data from the MOD090-LP. The Data Ready line (pin 9) will be asserted when data is present in the receive FIFO and will remain asserted until all data is read. Once the Data Ready line has been asserted the host microcontroller has approximately 50ms until the data becomes corrupted in a high traffic scenario. Obviously in UART mode, the host microcontroller must be ready to receive data at any time.
User’s Manual MOD090-LP BC = 0 means send the packet only to the Device ID specified in the rest of Byte 1. ID0 to ID6 is the 7-bit integer Device ID of the Subscriber Unit that is to receive the data. Note that if BC = 1 and there is a non-zero Device ID specified, then all Subscribers but the one specified will receive the data. S0 to S10 is the 11-bit integer size of the Data packet in bytes (number of data bytes being sent).
