XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 3. RF Modem Operation 3.1. Serial Communications 3.1.1. RS-232 and RS-485/422 Data Flow Devices that have a UART interface can connect directly through the pins of the XStream Modem as is shown in the figure below. Figure 3.1. System Data Flow Diagram in a UART-interfaced environment (Low-asserted signals distinguished with horizontal line over signal name.) 3.1.2.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 3.1.3. Flow Control Figure 3.2. Internal Data Flow Diagram (The five most commonly-used pin signals are shown.) DI (Data In) Buffer and Flow Control When serial data enters the XStream Modem through the DI Pin, then the data is stored in the DI Buffer until it can be transmitted.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 3.2. Modes of Operation XStream RF Modems operate in five modes. Figure 3.3. XStream Modes of Operation Modem can only be in one mode at a time. 3.2.1. Idle Mode When not receiving or transmitting data, the modem is in Idle Mode. The modem uses the same amount of power in Idle Mode as it does in Receive Mode.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Figure 3.4. Data Transmission Sequence RF Data Packet The RF packet is the sequence of data used for communicating information between Digi Modems. An RF Packet consists of an RF Initializer and RF Data. Figure 3.5. RF Data Packet Components * When streaming multiple RF packets, the RF Initializer is only sent in front of the first packet. RF Initializer An RF initializer is sent each time a new connection sequence begins.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 3.2.3. Receive Mode If the modem detects RF data while in Idle Mode, the modem transitions into Receive Mode to receive RF packets. Once a packet is received, the modem checks the CRC to ensure that the data was transmitted without error. If the CRC data bits on the incoming packet are invalid, the packet is discarded. If the CRC is valid, the packet proceeds to the DO Buffer.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Pin Sleep (SM = 1) Pin Sleep requires the least amount of power. In order to achieve this state, the DI3 (SLEEP) pin must be asserted (high). The modem remains in Pin Sleep until the DI3 pin is de-asserted. After enabling Pin Sleep, the SLEEP pin controls whether the XStream Modem is active or in Sleep Mode. When DI3 is de-asserted (low), the modem is fully operational.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Cyclic Scanning. Each RF transmission consists of an RF Initializer and payload. The wake-up initializer contains initialization information and all receiving modems must wake during the wake-up initializer portion of data transmission in order to be synchronized with the transmitting modem and receive the data. Figure 3.7. Correct Configuration (LH > SM) Length of the wake-up initializer exceeds the time interval of Cyclic Sleep.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 3.2.5. Command Mode To modify or read modem parameters, the modem must first enter into Command Mode, the state in which incoming characters are interpreted as commands. Two command types are available for programming the modem: • AT Commands • Binary Commands For modified parameter values to persist in the modem registry, changes must be saved to nonvolatile memory using WR (Write) Command.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Binary Commands Sending and receiving parameter values using binary commands is the fastest way to change operating parameters of the XStream RF Modem. Binary commands are used most often to sample signal strength (RS parameter) and/or error counts; or change modem addresses and channels for polling data systems.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 4. RF Modem Configuration 4.1. Automatic DIP Switch Configurations Each time the RF Modem is powered-on, intelligence on the XIB-R Interface Board (RS-232/485 interfacing board located inside the RF Modem) sends AT Commands that program the RF Modem based on positions of the DIP Switch. Automatic configurations that take place during the poweron sequence affect stored RF Modem parameter values as shown in the tables below. Figure 4.1.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 4.2. Programming Examples For information about entering and exiting AT and Binary Command Modes, refer to the Command Mode section (p19). 4.2.1. AT Commands Digi has provided XCTU software for programming the modem using an extensive list of AT Commands.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 EXAMPLE: Restore RF Modem Defaults using the Terminal tab The following steps show how to read currently stored modem parameter values; then restore the modem parameters to their factory-default states.

XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 HT (Time before Wake-up Initializer) Command < If any modems within AT Command: ATHT range are running in a “Cyclic Sleep” setting, a Binary Command: 0x03 (3 decimal) wake-up initializer must be used by the Parameter Range: 0 – 0xFFFF transmitting modem for sleeping modems to (x 100 milliseconds) remain awake (refer to the LH (“Wake-up Default Parameter Value: 0xFFFF (means that Initializer Timer”) Command).
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 LH (Wake-up Initializer Timer) Command LH Command adjusts the duration of time for which the RF initializer is sent. When receiving modems are put into Cyclic Sleep Mode, they power-down after a period of inactivity (specified by ST (Time before Sleep) command) and will periodically awaken and listen for transmitted data. In order for the receiving modems to remain awake, they must detect ~35ms of the wake-up initializer.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 MY (Source Address) Command Set/Read the source address of the modem. AT Command: ATMY Refer to the Addressing section (p41) of the RF Communication Modes chapter for more information.

XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 SY (Time before Initialization) Command SY Command keeps a communication channel open as long as modem transmits or receives before the active connection expires. It can be used to reduce latency in a query/response sequence and should be set 100 ms longer than the delay between transmissions.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 TT (Streaming Limit) Command TT Command defines a limit on the number of bytes that can be sent out before a random delay is issued. TT Command is used to simulate full-duplex behavior. AT Command: ATTT If a modem is sending a continuous stream of RF data, a delay is inserted which stops its transmission and allows other modems time to transmit (once it sends number of bytes specified by TT Command).
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5. RF Communication Modes 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, Repeater, Acknowledged or Multi-Streaming) The following table provides a summary of the network configurations supported. Table 5.1.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5.1. Addressing Each RF packet contains addressing information that is used to filter incoming RF data. Receiving modems 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 5.1). Figure 5.1. Filtration layers contained in the RF packet header 5.1.1.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5.2. Basic Communications Basic Communications are accomplished through two sub-types: • Broadcast - By default, XStream Modems communicate through Broadcast communications and within a peer-to-peer network topology. When any modem transmits, all other modems within range will receive the data and pass it directly to their host device.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5.2.2. Repeater Mode Characteristics: Self-organizing - No route configuration is necessary Self-healing / Fault-tolerant Low power consumption and Minimized interference Network throughput is determined by number of hops, not by number of repeaters. Multiple repeaters within range of source node count as one hop. Supports “transparent” multi-drop mode or addressed data filtering mode. Duplicate RF packets are automatically filtered out.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 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. The repeater network can be configured to operate using Basic Broadcast or Basic Addressed communications. The addressing capabilities of the modems allow integrators to send a packet as a global packet (DT = 0xFFFF) and shift out of every radio in the network (Basic Broadcast).
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 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.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5.3. Acknowledged Communications 5.3.1. Acknowledged Mode Characteristics: 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. Recommended Use: Acknowledge Mode configuration is appropriate when reliable delivery is required between modems.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 After receiving and acknowledging a packet, the receiving modem will move to the next frequency and listen for either a retransmission or new data for a specific period of time. Even if the transmitting modem has indicated that it has no more pending transmit data, it may have not received the previous ACK, and so it may retransmit the packet (potentially with no delay after the ACK slot).
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 5.3.2. Multi-Streaming Mode Characteristics: definition) Enables exclusive connections (refer to Theory of Operation section for Supports the passing of large data streams (> 256 bytes) from multiple remote modems to a base modem (If a complete data stream from a remote modem is less than 256 bytes, data can be sent from several remotes to a base location without enabling this mode and latencies will be much less.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Initiating a Connection Connection Guidelines: • A remote modem can only request a connection with the base modem. • The base modem may hold off or grant a connection request to another modem. • A remote modem will not try to establish a connection if one already exists. • A connection fails if no response is received after RR (Retries) CRP packets. After a failure, whatever condition was causing a connection to be established is cleared.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Configuration AT Command Mode AT command mode is used for all commands on base and remote modems. Binary command mode is not available when MD = 1 or 2. The base is in AT command mode when not engaged in an exclusive connection with a remote. No AT Command Mode sequence is needed. When a base modem is connected to a remote modem, the AT Command Mode sequence is used to enter AT command mode. The connection with the remote is maintained.
XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00 Sleep Modes and Connections Cyclic sleep can be used with the remote modems to conserve power. ST “Time before Sleep” Parameter defines how long after a disconnect a remote will stay awake. A modem is not allowed to enter sleep mode when it is engaged in a connection. A modem will wake as defined by SM parameter and check for an RF message.
