    TS4000 Overview The TS4000 Radio Modem is an integrated radio and modem designed for the Introduction wireless transmission of digital data. The TS4000 can transfer data at rates greater than 19,200 bits per second. The TS4000 includes a synthesized VHF, UHF or 900 MHz transceiver that can be programmed for up to 99 channels.
  • Page 8: Radio Modules

    Integrated AirNet Packet Data Protocol Allows user directed transmissions to only selected destinations. Provides addressed communications for devices that are not directly addressable themselves. Can be optimized for point to point, point to multi-point, and full mesh networks. Supports group and all-call broadcast transmissions. Built in CSMA/CA algorithm minimizes transmission collisions to maximize channel efficiency and utilization.
  • Page 9: Channel Spacing And Bandwidth

    transmit attack time (amount of time to initiate a transmission) does not have to increased excessively. For some frequency bands, there are multiple options for the radio module Channel Spacing and channel spacing and bandwidth. Bandwidth Channel Spacing The channel spacing defines how close together the channels are within a band (i.e.

    PC files. Details about the configuration controls are available later in this manual and in the on line help of the configuration program. Teledesign provides general-purpose wireless modem test software called Testing the TS4000 AirTest. AirTest can send data and gather performance statistics, including BER (Bit Error Rate), about the link between two modems.
  • Page 12: Status Leds

    The TS4000 has three LED indicators to provide operational status of transmit Status LEDs (TX), receive (RX) and power (PWR) functions. Special combinations of these indicators are used to indicate secondary operating modes and fault conditions. TS4000 State LEDs Indicator State Normal Operation On when the TS4000 is powered.
  • Page 13: Configuration Program

    Configuration Program The configuration program is used to configure the TS4000 for operation. Configuring the TS4000 consists of independently configuring both the modem operation and the radio frequency channels. The configuration program consists of controls and menus. The controls set the configuration and test options. The menus (line items at the top of the screen) execute program commands.

  • Page 16: Rs-232 Serial Port

    Serial Port The serial port provides an asynchronous data connection between the TS4000 and the host equipment. The TS4000 serial port is a standard RS-232 serial port with a number of options to allow connection to a wide variety of serial host equipment.
  • Page 17: Serial Port Connector

    The most common form of hardware flow control, and the one used by most full duplex wired (as opposed to wireless) modems, is RTS/CTS. With RTS/CTS flow control, RTS provides flow control for the DTE and CTS provides flow control for the DCE.
  • Page 18: Configuration Options

    connecting the TS4000 to other serial devices. For most serial devices this is not a problem because RI is a modem (DCE) output and the TS4000 power supply mostly falls within the allowed voltage range for RS-232 signals. Therefore the power voltage on this pin is interpreted as an active RI signal.
  • Page 19 The baud rate list provides selection of the serial port asynchronous baud rate. Baud Rate List The available selections are 1200, 2400, 4800, 9600, 19200 and 38400 baud. These options set the number of data bits in each asynchronous character. Data Bits Parity These options set the parity of the asynchronous characters.
  • Page 20 This option only has effect if packet operation is not enabled. Wait For Complete Burst Before Beginning Selection Description Transmission Disabled The modem begins transmitting as soon as it receives the first non-control character of a transmit burst. Enabled The modem waits for a complete transmit burst before it begins transmitting.
  • Page 21 CTS Line Control Selection Description Always Active The CTS line is active. Active when Transmitter is CTS is normally inactive and is activated when the Sending Data TS4000 is transmitting and the radio channel is ready for the transmission of data. Active when Transmitting CTS is normally inactive and is activated when the TS4000 is transmitting.
  • Page 22: Radio Setup

    Radio Setup The radio setup requires setting the modem configuration options and also setting the radio frequencies. The modem configuration options are accessed on the Radio tab of the Modem Configuration. The frequency programming is accessed with the Frequency Configuration button on the main screen of the configuration program.

  • Page 25: Channel Switching

    Radio vs. File Settings The minimum and maximum frequencies and the channel spacing depend on the specific radio module in the TS4000. The configuration program does not know this information unless it is connected to the TS4000. Therefore, these fields in the Radio Settings frame only show up when the configuration program is connected to the TS4000.

The response string is sent out the serial port and is as follows. +TSCxx Where: xx = Channel number from 01 to 99 Invalid Channel Selection If a frequency channel is selected that has not been programmed with valid frequencies, the modem will not receive or transmit and the RX and TX LEDs will alternately flash.
  • Page 27: Airnet Packet Protocol

    AirNet Packet Protocol AirNet is an embedded packet protocol available in some Teledesign Systems Overview modems. AirNet provides a complete protocol that manages the end to end data transfers of wireless networks. The AirNet protocol is flexible and configurable so that it can be used with any host (user) system or network architecture.
  • Page 28: Configuration Options

    logistically difficult and may not completely solve all propagation problems. The AirNet protocol provides an option where nodes can be set up as store and forward relays. The relay nodes store packets that they receive and repeat (forward) the packets when the channel is idle. The relay nodes can be set to relay all packets or only packets with certain source or destination addresses.
  • Page 29 Packet Activate Selection Description Enable Packet This activates packet operation for all user data. Operation The type of Medium Access Control (MAC) determines how a modem decides Medium (Channel) Access when to transmit packets. This effects the transmission of both data and Control (MAC) acknowledgment packets.
  • Page 30 CSMA MAC Setup Control Description Slot Time This sets the transmit slot time (see Setting Slot Time). Min Idle Slots This sets the minimum number of idle slots before a modem attempts transmission (see Setting Min Idle Slots). If the minimum number of idle slots is set to zero the modem randomizes its transmission attempts with the first slot after the channel becomes idle.
  • Page 31: Packet For Port

    Individual Packets - Relay Selection Description Activate None No individually addressed packets are relayed. Some The individual packets that are relayed is determined by the individual relay addresses control. All individually addressed packets are relayed. The exception is packets whose final destination is the relay node.
  • Page 32 Control Description Enable Multicast This control enables the multicast capability of the modem Reception and also enables the entry of multicast groups. Multicast Groups This control is a list of multicast addresses. These addresses have the same range as the group addresses. The user can use as few or as many (up to the list size) multicast groups as desired.

  • Page 41: Setting Tx Index

    For systems with one or more relay nodes, the simplest and most efficient system Systems with Relays setup is where each relay is assigned a particular slot. This way the relays do not collide or contend for the channel the way data packets do. The data packets are set so that they will leave the necessary number of slots open for the relays and ACK packets.
