    A complete listing of the available AT commands is included in Section 7.0. The WINC 900A operates in the 902-928 MHz frequency band with a maximum power of 1 watt. Eight independent 3 MHz wide channels are available within this band. Outdoors, the operating range of the modem is approximately 1 kilometer.
  • Page 7 If anything is missing or damaged, please contact your supplier immediately. Each WINC 900A is uniquely identified by an seven (7) digit address that is used when two units attempt to establish a communications link. The seven (7) digit address is found on the label affixed to the left side of the unit and is defined by the right-most seven (7) digits of the serial number.

  • Page 19: Winc 900A Interface Status

    The WINC 900A interface status refers to the state of the RS-232 serial port between the local terminal or computer and the WINC 900A. The state, in turn, is determined by the signal levels on each of the signal lines that comprise the serial port. These status lines have been brought to the front panel in the form of a series of eight (8) light emitting diodes (LED).
  • Page 20 When the default reset button is pressed, the WINC 900A either defaults to the factory preset configuration of 9600 bps, 8 bits per character, no parity, 1 stop bit, hardware flow control, and auto answer or resets to the previously configured state.

  • Page 21: At Command Set

    7.0 AT Command Set At any given time the WINC 900A is in either one of two modes, the command mode or the on-line mode. When in the command mode, the device accepts commands from the host computer. These commands are sent to the WINC 900A as character strings composed of printable ASCII characters.

  • Page 22: Basic At Commands

    The WINC 900A is designed to respond to the following Hayes compatible AT commands. A - Answer On-line The command ATA causes the WINC 900A to cease accepting commands and to wait for an incoming connection request for up to register S7 seconds. If a pending connection request is present, the device accepts the connection and enters the on-line state.
  • Page 23 Discard pending data, close connection immediately and leave the network. Result codes: Valid argument. ERROR Invalid argument. I - Identify The ATI command returns information about the WINC 900A or equivalent DCE device. Format: ATI0 Identifies modem’s address. ATI1 Identifies software (firmware) release number. ATI2 Identifies manufacturer.
  • Page 24 Result Codes: ERROR Connection does not exist. CONNECT Successful return to on-line mode. Q - Quiet Mode The ATQ command controls whether result codes are sent to the host computer. If this command is selected, the V and X commands may further modify the result codes. Format: ATQ0 Modem sends responses to host computer.
  • Page 25 Result codes: Valid parameter. ERROR Invalid value for selected register. V - Verbal Result Codes The ATV command determines whether the device sends a numeric digit (terse mode) or an informative text string (verbose mode). Format: ATV0 Use numeric result codes. ATV1 Use text string result codes.
  • Page 26 For serial ports, the AT&C command defines the operation of the data carrier detect signal (DCD) at the modem interface. Format: AT&C0 DCD always active. AT&C1 DCD follows the state of “Connection Established” condition, which is the default. AT&C2 DCD always on, except momentarily at connection disconnect.

    Format: AT&L<speed>,<databits><parity><stopbits> AT\C - Select Communications Channel Although the WINC 900A automatically selects the best channel over which to communicate, the communications channel may be changed using the AT\C command. Format: AT\C0 Channel 0, 925 MHZ...
  • Page 28 AT&!S Activate the short spreading code. AT&!L Activate the long spreading code. &!n - Automatic Re-connection Control The AT&!n command determines whether the automatic re-connection feature is enabled. If enabled, this command must be preceded by the command AT~A<address>, where <address>=remote terminal address or identifier.

  • Page 29: S Registers

    Enable automatic timed transmission according to register S50. 7.4 S Registers The configuration of the WINC 900A is accessible to the host computer as a set of parameters stored in a set of S registers. Some registers may be updated directly with AT commands and others are read-only.
  • Page 30 Viewing the Current Profile The current configuration, or active profile, of the WINC 900A can be viewed at any time by using the AT&V command. In response to this command, the configuration state of all registers will be displayed.
  • Page 31 Verifying the Local Address Each WINC 900A has been identified at the factory with a unique address (identical to the serial number listed on the label on the left-hand side of the unit) . For a remote terminal, this represents the destination address.

    0.01sec time S-REGISTER DEFINITIONS : The behaviors of WINC 900A can be adjusted via the AT commands and the content of register to meet application’s requirement. S0 Rings to Auto-Answer Whether this unit will be able to answer the request for connection from the remote caller automatically or manually is decided by the content of the register 0.
  • Page 36 The ATD command begins a transaction for establishing a connection with a remote party. The WINC 900A transmits a connection setup request containing the destination address given on the command line and waits for up to register S7 seconds for a response. If the connection request is not accepted, the device returns to the command state.
  • Page 37 Bit 0 Unused Bits 1,2,3 (value, data rate): (0, 1.2), (1, 2.4), (2, 4.8), (3, 9.6), (4, 19.2),(5, 38.4) Bits 4,5 Unused Bits 6,7 (value, parity): (0, even), (1, none), (2, odd), (3, mark) S50 Data forwarding idle time-out The data from the connected external device will stay in a system buffer and packetized for transmission process.
  • Page 38 WINC 900A will switch into idle mode and exchange packets to maintain the established link. The in-coming data from the physical connected will be detected and the WINC 900A will return to the burst mode. But, there is a delay during the wake-up process. This idle mode can be disabled via the register 60.
  • Page 39 S63 Enable the detect function or Listening time. To avoid the packet collision situation in the transparent mode, each unit will listen/monitor the traffic on the air. The data transmission process will be executed if there is no traffic on the air for a defined period time. Otherwise the transmission process will be on hold and the monitoring function will re- instated after a random time.
