2. RF Module Operation WARNING: When operating at 1 Watt power output, observe a minimum separation distance of 2' (0.6m) between modules. Transmitting in close proximity of other modules can damage module front ends. Serial Communications The XTend OEM RF Modules interface to a host device through a TTL-level asynchronous serial port.
9XTend™ OEM RF Module - Product Manual v2.x6x Flow Control Figure 2-03. Internal Data Flow Diagram (The ve most commonly-used pin signals shown) DI (Data In) Buffer and Flow Control When serial data enters the module through the DI pin (pin 5), the data is stored in the DI Buffer until it can be processed. When the RB and RO parameter thresholds are satisfied (refer to ‘Transmit Mode’ section for more information), the module attempts to initialize an RF connection.
9XTend™ OEM RF Module - Product Manual v2.x6x Transparent Operation By default, XTend RF Modules operate in Transparent Mode. The modules act as a serial line replacement - all UART data received through the DI pin is queued up for RF transmission. When RF data is received, the data is sent out the DO pin. When the RO (Packetization Timeout) parameter threshold is satisfied, the module attempts to initialize an RF transmission.
9XTend™ OEM RF Module - Product Manual v2.x6x Modes of Operation XTend RF Modules operate in six modes. Figure 2-04. XTend RF Module Modes of Operation (RF modules can only be in one mode at a time) Idle Mode When not receiving or transmitting data, the RF module is in Idle Mode.
9XTend™ OEM RF Module - Product Manual v2.x6x Channel initialization is the process of sending an RF initializer that synchronizes receiving modules with the transmitting module. During channel initialization, incoming serial data accumulates in the DI buffer. RF data, which includes the payload data, follows the RF initializer. The payload includes up to the maximum packet size (PK Command) bytes.
9XTend™ OEM RF Module - Product Manual v2.x6x Figure 2-07. Receive Mode Data Flow * Refer to the ‘Address Recognition’ section for more information regarding address recognition. The module returns to Idle Mode when valid RF data is no longer detected or after an error is detected in the received RF data. If serial data is stored in the DI buffer while the module is in Receive Mode, the serial data will be transmitted after the module is finished receiving data and returns to Idle Mode.
9XTend™ OEM RF Module - Product Manual v2.x6x In order to enter Sleep Mode, one of the following conditions must be met (in addition to the module having a non-zero SM parameter value): 1. The module is idle (no data transmission or reception) for the amount of time defined by the ST (Time before Sleep) parameter. [NOTE: ST is only active when SM = 4-5.] 2. SLEEP (pin 8) is asserted (only for the ‘Pin Sleep’ option).
9XTend™ OEM RF Module - Product Manual v2.x6x The period of time the module sleeps is determined by ST (Time before Sleep) Command. Once a character is received through the DI pin, the module returns to Idle Mode and is fully operational. Cyclic Sleep (SM = 4-8) Typical Power-down Current: < 1.6 mA (when asleep) Cyclic Sleep Modes allow modules to periodically wake and check for RF data. The module wakes according to the times designated by the Cyclic sleep settings.
9XTend™ OEM RF Module - Product Manual v2.x6x AT Command Mode To Enter AT Command Mode: 1. Send the 3-character command sequence "+++" and observe guard times before and after the command characters. [refer to ‘Default AT Command Mode Sequence’ below.] The ‘Terminal’ tab (or other serial communications software) of the X-CTU Software can be used to enter the sequence. 2. Assert (low) the CONFIG pin and turn the power going to the module off and back on (or pulse the SHDN pin).
9XTend™ OEM RF Module - Product Manual v2.x6x After sending serial data, is there a minimum time delay before CMD can be asserted? Is a time delay required after CMD is de-asserted before payload data can be sent? How does one discern between live data and data received in response to a command? The CMD pin (pin 10) must be asserted in order to send binary commands to the module. The CMD pin can be asserted to recognize binary commands anytime during the transmission or reception of data.
3. RF Module Programming Examples Refer to the ‘Command Mode’ section [p17] for information regarding entrance into Command Mode, sending AT commands and exiting Command Mode. Refer to the ‘X-CTU’ section [p81] of the ‘Development Guide’ for more information regarding MaxStream’s configuration software.
9XTend™ OEM RF Module - Product Manual v2.x6x Command Reference Table Table 3-01. XTend Commands (The RF modules expect numerical values in hexadecimal. Hexadecimal values are designated by a “0x” pre x. Decimal equivalents are designated by a “d” su x.
9XTend™ OEM RF Module - Product Manual v2.x6x Table 3-01. XTend Commands (The RF modules expect numerical values in hexadecimal. Hexadecimal values are designated by a “0x” pre x. Decimal equivalents are designated by a “d” su x.
9XTend™ OEM RF Module - Product Manual v2.x6x Command Descriptions Commands in this section are listed alphabetically. Command categories are designated between the "< >" symbols that follow each command title. By default, XTend RF Modules expect numerical values in hexadecimal since the default value of the CF (Number Base) Parameter is '1'. Hexadecimal values are designated by the "0x" prefix and decimal values by the "d" suffix.
9XTend™ OEM RF Module - Product Manual v2.x6x BD (Interface Data Rate) Command The BD command is used to set and read the serial interface data rate (baud rate) used between the RF module and host. This parameter determines the rate at which serial data is sent to the module from the host. Modified interface data rates do not take effect until the CN (Exit AT Command Mode) command is issued and the system returns the 'OK' response.
9XTend™ OEM RF Module - Product Manual v2.x6x BT (Guard Time Before) Command The CC command is used to set/read the ASCII character used between guard times of the AT Command Mode Sequence (BT + CC + AT). This sequence enters the module into AT Command Mode so that data entering the module (from the host) is recognized as commands instead of payload. Refer to the ‘AT Command Mode’ section [p17] for more information regarding the AT Command Mode Sequence.
9XTend™ OEM RF Module - Product Manual v2.x6x CN (Exit AT Command Mode) Command The CN command is used to explicitly exit the module from AT Command Mode. AT Command: ATCN Binary Command: 0x09 (9 decimal) CS (GPO1 Configuration) Command CS Command is used to select the behavior of the GP01 pin (pin 9). This output can provide RS-232 flow control, control the TX enable signal (for RS-485 or RS-422 operations).
9XTend™ OEM RF Module - Product Manual v2.x6x DT (Destination Address) Command DT Command is used to set/read the networking address of an RF module. The modules utilize three filtration layers: Vendor ID Number (ATID), Channel (ATHP), and Destination Address (ATDT). The DT command assigns an address to a radio that enables it to communicate with other radios in the network.
9XTend™ OEM RF Module - Product Manual v2.x6x FL (Software Flow Control) Command The FL command is used to configure software flow control. Hardware flow control is implemented with the module as the GP01 pin (CTS pin of the OEM RF module), which regulates when serial data can be transferred to the module. FL Command can be used to allow software flow control to also be enabled. The XON character used is 0x11 (17 decimal).
9XTend™ OEM RF Module - Product Manual v2.x6x HP (Hopping Channel) Command The HP command is used to set/read the RF module's hopping channel number. A channel is one of three layers of filtration available to the module. In order for modules to communicate with each other, the modules must have the same channel number since each channel uses a different hopping sequence. Different channels can be used to prevent modules in one network from listening to transmissions of another.
9XTend™ OEM RF Module - Product Manual v2.x6x KY (AES Encryption Key) Command The KY command is AT Command: ATKY used to set the 256-bit AES (Advanced Encryption Binary Command: 0x3C (60 decimal) Standard) key for encrypting/decrypting data. Parameter Range: Once set, the key cannot be read out of the mod0 - (64 hex digits all set to 'F') ule by any means.
9XTend™ OEM RF Module - Product Manual v2.x6x MD (RF Mode) Command The MD command is used to select/read the settings that enable the Polling and Repeater Modes on the module. Polling Mode - A ‘Polling Base’ is responsible for polling remotes. A ‘Polling Remote’ requires a poll in order to transmit.
9XTend™ OEM RF Module - Product Manual v2.x6x Refer to the ‘Multi-transmit Mode’ section [p46] for more information. MY (Source Address) Command The MY command is used to set/read the Source Address of the RF module. Refer to the DT command and the 'Addressing' section [p45] for more information.
9XTend™ OEM RF Module - Product Manual v2.x6x PE (Polling End Address) Command PE command is used to set/read the module’s Polling End Address - the last address polled when Polling Mode is enabled. AT Command: ATPE Binary Command: 0x46 (70 decimal) Parameter Range: 0 - 0xFFFF Polling Operations: The ‘Polling Base’ (MD = 3) Default Parameter Value: 0 cycles through a sequential range of addresses, polling each ‘Polling Remote’ (MD = 4).
9XTend™ OEM RF Module - Product Manual v2.x6x PW (Pin Wake-up) Command Under normal operation, an RF module in Cyclic Sleep Mode cycles from an active state to a low-power state at regular intervals until data is ready to be received. If the PW parameter is set to 1, the SLEEP pin (pin 8) can be used to awaken the module from Cyclic Sleep. When the SLEEP Pin is de-asserted (low), the module will be fully operational and will not go into Cyclic Sleep.
9XTend™ OEM RF Module - Product Manual v2.x6x RM (Ambient Power - All Channels) Command The RM command is used to examine and report power levels on all channels. If no parameter is given, the channels are scanned one time. If a parameter is given, the channels are repeatedly scanned for that number of seconds. The maximum power level seen for each channel is reported (i.e. peak hold).
9XTend™ OEM RF Module - Product Manual v2.x6x The correct UART character time (10, 11, or 12 bits) is calculated based on the following criteria: 1 start bit 8 data bits 0 or 1 parity bit [as determined by the NB (Parity) Command) 1 or 2 stop bits [as determined by SB (Stop Bits) Command] © 2010 Digi Internatonal, Inc.
9XTend™ OEM RF Module - Product Manual v2.x6x RP (RSSI PWM Timer) Command RP Command is used to enable a PWM ("Pulse Width Modulation") output on the Config/RSSI pin (pin 11 of the OEM RF Module). The pin is calibrated to show the difference between received signal strength and the sensitivity level of the RF module. PWM pulses vary from zero to 95 percent. Zero percent means the received RF signal is at or below the published sensitivity level of the module.
9XTend™ OEM RF Module - Product Manual v2.x6x RT (GPI1 Configuration) Command The RT command is used to set/read the behavior of the GPI1 pin (pin 10) of the OEM RF Module. The pin can be configured to enable binary programming or RTS flow control.
9XTend™ OEM RF Module - Product Manual v2.x6x SM (Sleep Mode) Command The SM Command is used to set/read the RF module's Sleep Mode settings that configure the module to run in states that require minimal power consumption. For more information regarding Sleep Modes, refer to the Sleep Mode sections [p14] AT Command: ATSM Binary Command: 0x01 Parameter Range: 0 - 8 (3 is reserved) Parameter Configuration 0 Disabled 1 Pin Sleep 2 Serial Port Sleep 3 [reserved] 4 Cyclic 1.
9XTend™ OEM RF Module - Product Manual v2.x6x TR (Transmit Error Count) Command The TR command is used to report the number of retransmit failures. This number is incremented each time a packet is not acknowledged within the number of retransmits specified by the RR (Retries) parameter. The number of packets therefore are counted that were not successfully received and subsequently discarded.
9XTend™ OEM RF Module - Product Manual v2.x6x WA (Active Warning Numbers) Command The WA command reports the warning numbers of all active warnings - one warning number per line. No further information is shown and warning counts are not reset. AT Command: ATWA Parameter Range:Returns string - one warning number per line.
9XTend™ OEM RF Module - Product Manual v2.x6x API Operation By default, XTend RF Modules act as a serial line replacement (Transparent Operation) - all UART data received through the DI pin is queued up for RF transmission. When the module receives an RF packet, the data is sent out the DO pin with no additional information.
9XTend™ OEM RF Module - Product Manual v2.
9XTend™ OEM RF Module - Product Manual v2.x6x TX (Transmit) Request: 16-bit address API Identifier Value: 0x01 A TX Request message will cause the module to send RF Data as an RF Packet. Figure 3-5.
4. RF Communication Modes The network configurations covered in this chapter are described in terms of the following: Network Topology (Point-to-Point, Point-to-Multipoint or Peer-to-Peer) RF Communication Type (Basic or Acknowledged) RF Mode (Streaming, Multi-Transmit, Repeater, Acknowledged or Polling) Note: Please see the DigiMesh chapter for additional information on networking features. The following table provides a summary of the network configurations supported. Table 4-01.
9XTend™ OEM RF Module - Product Manual v2.x6x Addressing Each RF packet contains addressing information that is used to filter incoming RF data. Receiving modules inspect the Hopping Channel (HP parameter), Vendor Identification Number (ID parameter) and Destination Address (DT parameter) contained in each RF packet. Data that does not pass through all three network security layers is discarded. Figure 4-01.
9XTend™ OEM RF Module - Product Manual v2.x6x Basic Communications Basic Communications are accomplished through two sub-types: Broadcast - By default, XTend RF Modules communicate through Broadcast communications and within a peer-to-peer network topology. When any module transmits, all other modules within range will receive the data and pass it directly to their host device.
9XTend™ OEM RF Module - Product Manual v2.
9XTend™ OEM RF Module - Product Manual v2.x6x Repeater Mode Attributes:Low power consumption Minimized interference Each RF packet is tagged with a unique Packet ID (PID). Each repeater will repeat a packet only once (tracked by the PID). Increased latency and decreased throughput (Latency and throughput is determined by number of hops, not by number of repeaters. Multiple repeaters within range of source node count as one hop.
9XTend™ OEM RF Module - Product Manual v2.x6x Repeater Network Configuration A network may consist of End Nodes (EN), End/Repeater Nodes (ERN) and a Base Node (BN). The base node initiates all communications. A repeater network can be configured to operate using Basic Broadcast or Basic Addressed communications. The addressing capabilities of the module allow integrators to send a packet as a global packet (DT = 0xFFFF) and shift out of every module in the network (Basic Broadcast).
9XTend™ OEM RF Module - Product Manual v2.x6x Response Packet Delay As a packet propagates through the repeater network, if any node receives the data and generates a quick response, the response needs to be delayed so as not to collide with subsequent retransmissions of the original packet. To reduce collisions, both repeater and end node radios in a repeater network will delay transmission of data shifted in the serial port to allow any repeaters within range to complete their retransmissions.
9XTend™ OEM RF Module - Product Manual v2.x6x Polling Mode (Basic) NOTE: Polling Mode (Basic) and Polling Mode (Acknowledged) [p53] operate in the same way. The only difference between the two modes is in their means of achieving reliable delivery of data. In Polling Mode (Basic), reliable delivery is achieved using multiple transmissions.
9XTend™ OEM RF Module - Product Manual v2.x6x Acknowledged Communications Acknowledged Mode Attributes:Reliable delivery through positive acknowledgements for each packet Throughput, latency and jitter vary depending on the quality of the channel and the strength of the signal. Required Parameter Values (TX module): RR (Retries) >= 1 Related Commands: Networking (DT, MK, RR), Serial Interfacing (PK, RN, RO, RB, TT) Recommended Use: Use for applications that require Reliable Delivery.
9XTend™ OEM RF Module - Product Manual v2.x6x The TT parameter (streaming limit) specifies the maximum number of bytes that the TX module will send in one transmission event, which may consist of many packets and retries. If the TT parameter is reached, the TX module will force a random delay of 1 to RN delay slots (exactly 1 delay slot if RN is zero). Each packet is counted only once toward TT, no matter how many times the packet is retransmitted.
9XTend™ OEM RF Module - Product Manual v2.x6x Polling Mode (Acknowledged) NOTE: Polling Mode (Acknowledged) and Polling Mode (Basic) [p50] operate in the same way. The difference between the two modes is in their means of achieving reliable delivery of data. In Polling Mode (Acknowledged), reliable delivery is achieved using retries and acknowledgements.
5. DigiMesh™ Introduction XTend OEM RF Modules containing firmware version 8020 (or above) now feature DigiMesh™ mesh networking support. Mesh networking allows messages to be routed through several different nodes to a final destination. The DigiMesh firmware allows OEMs and system integrators to bolster their networks with the self-healing attributes of mesh networking. In the event that one RF connection between nodes is lost (due to power-loss, environmental obstructions, etc.
9XTend™ OEM RF Module - Product Manual v2.x6x To send Unicast messages, set the DH and DL on the transmitting module to match the corresponding SH and SL parameter values on the receiving module. Broadcast Addressing Broadcast transmissions will be received and repeated by all nodes in the network. Because ACKs are not used the originating node will send the broadcast four times. Essentially the extra transmissions become automatic retries without acknowledgments.
9XTend™ OEM RF Module - Product Manual v2.x6x Example: Utilize the 'Terminal' tab of the X-CTU Software to change the module's DL (Destination Address Low) parameter and save the new address to non-volatile memory. This example requires the installation of MaxStream’s X-CTU Software and a serial connection to a PC.
