  • Page 10: Setting The Address

    Each device that can be connected via GP-IB has a unique address within the GP-IB system. This address is used to distinguish the device from others. Therefore, when you connect the WT1600FC to a PC, for example, make sure to assign a unique address to the WT1600FC.

  • Page 11: Response To Interface Messages

    Response to Interface Messages Response to Interface Messages Response to a uni-line message IFC (Interface Clear) Clears the talker and listener. Stops output if data is being output. REN (Remote Enable) Switches between remote and local modes. IDY (Identify) is not supported. Response to a multi-line message (address command) GTL (Go To Local) Switches to local mode.
  • Page 12 Secondary address address command Messages marked with a “★” are interface messages supported by the WT1600FC Note Differences between SDC and DCL The SDC command is an address command and requires that both the talker and listener be designated; however DCL is a universal command and does not require that the talker and listener be designated.

  • Page 17: Handshaking

    Handshaking To use an serial interface for transferring data between this instrument and a computer, it is necessary to use certain procedures by mutual agreement to ensure the proper transfer of data. These procedures are called “handshaking.” Various handshaking systems are available depending on the computer to be used; the same handshaking system must be used for both the computer and this instrument.
  • Page 18 2.4 Handshaking 3 XON-RS Transmission data control A software handshake status is established between the instrument and host computer. The instrument will stop a data transmission when an X-OFF signal is received from the host computer, and will resume transmission when the next X-ON signal is received.

  • Page 19: Matching The Data Format

    Matching the Data Format The serial interface of this instrument performs communications using start-stop synchronization. In start-stop synchronization, one character is transmitted at a time. Each character consists of a start bit, data bits, a parity bit and a stop bit. Refer to the figure below.
