    SECTION SYSTEM OPERATION...

  • Page 26: Data Transparent Mode

    With the exception of FDL01TU modem commands, all data input from the sending terminal are transmitted to the receiving terminal. Using this mode, the user can simply replace a serial cable with a pair of FDL01TU modems and communicate without any special software or hardware requirements.

  • Page 27: Packet Transmission Mode

    1:n and n:m topology applications. In packet transmission mode, the FDL01TU modem normally waits in a ready-to- receive state. When a transmission command is issued to the sender modem from its terminal equipment, the modem searches for a clear frequency channel and, when found, transmits the message to the intended destination receiver modem.
  • Page 28 Six transmit commands can be used in packet transmission mode . Both text and binary data can be sent directly from modem-to-modem or sent through a third FDL01TU modem configured as a repeater. The receiver modem automatically determines the transmitted data format and communication path from the information in the received packet header.
  • Page 29 The following list shows each command’s syntax as issued at the sender terminal equipment and the response displayed at the receiver terminal equipment when the packet is received. 1. Direct Text Data Transmission transmit: TXT [destination address]{source address}[message] receive: RXT [source address][message] CR/LF 2.

  • Page 30: Headerless Stream Mode

    Headerless stream Mode 3.3.1 Operation in the headerless stream mode The headerless stream mode is a specific transmission mode to set transmission data without the packet header, employing the protocol of the packet transmission mode. Parameters such as receiver or repeater addresses are set either by the memory register or by the command.

  • Page 31: Power Down Mode

    Set REG18:bit 5 whether the repeater is used or not. The address of the repeater is set using REG08 and REG09 or PAS command. Power Down Mode The FDL01TU has three power down modes. Select the mode according to the power supply operating conditions such as battery powered application. (1) Active Mode This mode is not the power down mode but always capable of transmitting and receiving data.

  • Page 32: Frequency Grouping

    Frequency Grouping 3.5.1 Frequency Allocation The FDL01TU can operate on 76 available frequencies between 2403 MHz and 2480 MHz with 1 MHz separation between each frequency. See the table below for the exact frequency assignments. Freq.No. Freq.(MHz) Freq.No. Freq.(MHz) ０...
  • Page 33 3.5.2 Frequency Group Operation The FDL01TU can operate on a fixed frequency or on any frequency in a set of frequency group. Multiple FDL01TU systems can be use different frequency groups and operate in the same area without mutual interference between the systems. When the RF environment is relatively clean, wireless channel links can be made on a fixed, clear frequency (no interference) by using Grouping Method A.
