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 RF Modules interface to a host device through a TTL-level asynchronous serial port.
XTend™ RF Module ‐ Product Manual Flow Control Figure 2‐03. Internal Data Flow Diagram (The five 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual Figure 2‐07. Receive Mode Data Flow * Refer to the ‘Address Recognition’ sec‐ tion 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.
XTend™ RF Module ‐ Product Manual 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).
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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. [OR] 2. Assert (low) the CONFIG pin and turn the power going to the module off and back on (or pulse the SHDN pin).
XTend™ RF Module ‐ Product Manual • 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 Configuration 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 [p71] of the ‘Development Guide’ for more information regarding Digi’s configuration software.
XTend™ RF Module ‐ Product Manual Command Reference Table XTend Commands (The RF modules expect numerical values in hexadecimal. Hexadecimal values are designated by a “0x” prefix. Decimal equivalents are designated by a “d” suffix.) AT Binary Command Command AT Command Name Parameter Range Command Category # Bytes Factory Returned Default %V 0x3B (59d) Board Voltage 0x2CCCA - 0x5BFFA [read-only] Diagnostics 4 -- AM 0x40 (64d) Auto-set MY -- Networking & Security -- -- AP v2.
XTend™ RF Module ‐ Product Manual XTend Commands (The RF modules expect numerical values in hexadecimal. Hexadecimal values are designated by a “0x” prefix. Decimal equivalents are designated by a “d” suffix.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual BT (Guard Time Before) Command BT Command is used to set the DI pin silence time that must precede the command sequence character (CC command) of the AT Command Mode sequence. Refer to the ‘AT Command Mode’ section [p18] for more information regarding the AT Command Mode Sequence.
XTend™ RF Module ‐ Product Manual 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). By default, GP01 provides RS-232 CTS (Clear-toSend) flow control.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual FL (Software Flow Control) Command The FL command is used to configure software flow control. Hardware flow control is implemented with the modual as the GP01 pin (CTS pin of the RF module), which regulates when serial data can be tranferred to the module.
XTend™ RF Module ‐ Product Manual hopping sequence. Different channels can be used to prevent modules in one network from listening to transmissions of another. HT (Time before Wake-up Initializer) Command The HT command is used to set/read the time of inactivity (no serial or RF data is sent or received) before a wake-up initializer is sent by a TX (transmitting) RF module.
XTend™ RF Module ‐ Product Manual from a module without a key, but the output will be meaningless. Because CBC mode is utilized, repetitive data appears differently in different transmissions due to the randomly-generated IV. NOTE: For international (non-U.S.) variants of XTend modules, the encryption key is 128-bit AES. The command operates the same except the key length is 16 bytes rather than 32 bytes.
XTend™ RF Module ‐ Product Manual MK (Address Mask) Command The MK command is used to set/read the Address Mask of a module. AT Command: ATMK Binary Command: 0x12 (18 decimal) All RF data packets contain the Destination Parameter Range:0 - 0xFFFF Address of the TX (transmitting) module.
XTend™ RF Module ‐ Product Manual NB (Parity) Command The NB command is used to select/read the parity settings of the RF module for UART communications.
XTend™ RF Module ‐ Product Manual PK (Maximum RF Packet Size) Command The PK command is used to set/ read the maximum size of RF packets transmitted from an RF module. The maximum packet size can be used along with the RB and RO parameters to implicitly set the channel dwell time. If PK is set above 256 and BR is subsequently changed to 0, PK will automatically be lowered to 256 and a warning will be raised (refer to the BR (RF Data Rate) and WN (Warning Data) commands for details).
XTend™ RF Module ‐ Product Manual RB (Packetization Threshold) Command The RB command is used to set/read the character threshold value.
XTend™ RF Module ‐ Product Manual RN (Delay Slots) Command The RN command is used to set/read the time delay that the transmitting RF module inserts before attempting to resend a packet. If the transmitting module fails to receive an acknowledgement after sending a packet, it inserts a random number of delay slots (ranging from 0 to (RN minus 1)) before attempting to resend the packet. Each delay slot is 5 msec (when BR=1) and 54 msec (when BR=0).
XTend™ RF Module ‐ Product Manual The following table shows dB levels above sensitivity and PWM values (The total time period of the PWM output is 8.32 ms. PWM output consists of 40 steps and therefore the minimum step size is 0.208 ms.): Table 3‐01. PWM Values dBm above sensitivity PWM percentage (high period / total period) 10 20% 20 35% 30 50% A non-zero value defines the time that PWM output is active with the RSSI value of the last received RF packet.
XTend™ RF Module ‐ Product Manual SH (Serial Number High) Command SH Command is used to set/read the serial number high word of the RF module. AT Command: ATSH Binary Command: 0x25 (37 decimal) Parameter Range (read-only): 0 - 0xFFFF Default Parameter Value: varies Number of bytes returned: 2 Related Commands: SL (Serial Number Low) SL (Serial Number Low) Command SL Command is used to set/read the serial number low word of the RF module.
XTend™ RF Module ‐ Product Manual ST (Time before Sleep) Command The ST Command is used to set/read the period of time (in milliseconds) in which the RF module remains inactive before entering Sleep Mode. For example, if the ST Parameter is set to 0x64 (100 decimal), the module will enter into Sleep mode after 10 seconds of inactivity (no transmitting or receiving).
XTend™ RF Module ‐ Product Manual TX (Transmit Only) Command The TX command is used to set/ read the transmit/receive behaviors of the RF module. Setting a module to TX-only (TX = 1) may reduce latency because the transmitting module will never be confined to receiving data from other modules.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual Data bytes that need to be escaped: • 0x7E – Frame Delimiter • 0x7D – Escape • 0x11 – XON • 0x13 – XOFF Example - Raw UART Data Frame (before escaping interfering bytes): 0x7E 0x00 0x02 0x23 0x11 0xCB 0x11 needs to be escaped which results in the following frame: 0x7E 0x00 0x02 0x23 0x7D 0x31 0xCB Note: In the above example, the length of the raw data (excluding the checksum) is 0x0002 and the checksum of the non-escaped data (excluding frame delimiter and length) is ca
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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 passit directly to their host device.
XTend™ RF Module ‐ Product Manual Multi-transmit Mode Attributes:Reliable Delivery through forced transmission of every RF packet Every RF packet is sent exactly (MT + 1) times with no delays between packets Diminished throughput and increased latency Required Parameter Values (TX module): MT (Multi-Transmit) >= 1 Other Related Commands: Networking (DT, MK, MY, RN, TT), Serial Interfacing (BR, PK, RB, RO), RF Interfacing (FS) Recommended Use: Use for applications that require Reliable Delivery without usin
XTend™ RF Module ‐ Product Manual 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.) All RF packets propagate to every module in the network (filtering rules apply).
XTend™ RF Module ‐ Product Manual 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).
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual Polling Mode (Basic) NOTE: Polling Mode (Basic) and Polling Mode (Acknowledged) [p51] 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual 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.
XTend™ RF Module ‐ Product Manual Polling Base Configuration: Set the MD (RF Mode) parameter (MD = 3). Set MY (Source Address) parameter (MY = 0). Set the sequential range of Polling Addresses using the PB (Polling Begin Address) and PE (Polling End Address) parameters. (Optional) Enable Acknowledged Reliable Delivery (RR >= 0). Note: Basic Reliable Delivery is also supported. Refer to the ‘Polling Mode - Basic section for more information.
