  • Page 11: Description Of The Gpib-Prl

    Introduction The GPIB-PRL, shown in Figure 1-1, provides a method of connecting a device with a Centronics-type interface port to the IEEE 488 (GPIB) bus. The GPIB-PRL allows transparent conversion of data between the two ports so that control codes or special commands are not required.

  • Page 12: What Your Kit Contains

    Centronics-type output port or to add a standard Centronics-type printer to a GPIB network. Although the GPIB-PRL is designed to be used with a device which adheres to the Centronics interface standard, it can also be used with other devices which use a unidirectional parallel 8-bit bus similar in nature to the Centronics specification.

  • Page 17: The Parallel Connector

    Chapter 1 Description of the GPIB-PRL The Parallel Connector The parallel connector is a standard 36-pin shielded AMP Champ female connector with bail-lock clips. The parallel connector will accept standard 36-pin Centronics-style male connectors. A diagram of the parallel connector and the signals supported is shown below (a * suffix indicates that the signal is active low).

  • Page 19: Installation And Operation

    If the parallel port is going to be the source of the data and a GPIB device will be the end recipient of the data (as with a GPIB plotter connected via a GPIB-PRL to the Centronics port on an IBM PC), you will be operating in P (Parallel) mode.

  • Page 20: Installation

    National Instruments for instructions. Step 2. Verify the Voltage Requirement The GPIB-PRL is shipped from the factory with either a 115 V or 230 V wall- mount supply. Verify that the voltage on the supply matches the voltage that is supplied in your area.

  • Page 21: Step 3. Configure The Operating Parameters

    The GPIB-PRL is shipped from the factory configured to operate in G mode and set to the GPIB primary address of 5. If you wish to use the GPIB-PRL in P mode or wish to change the GPIB primary address, it is necessary to open the unit and set the configuration switches.

    National Instruments. Operation The GPIB-PRL is now ready to operate. All characters sent to the unit will be received at full speed and stored in the internal data buffer. The characters will be sent to the receiving device at the rate of the receiving device.
  • Page 26 If using the GPIB-PRL in G mode, simply address the GPIB-PRL to listen (if not in listen-only mode) and send the desired data to the interface. The data will be received and passed along automatically to the device connected to the parallel port.

  • Page 27: Technical Information

    All operations are completely transparent to the user. If very large amounts of data are sent to the GPIB-PRL (greater than the amount of RAM in the system) and the parallel device is a very slow data acceptor, the GPIB-PRL internal data buffer might become full.
  • Page 28 GPIB-PRL so the GPIB can be used by other devices. If the GPIB-PRL is serial polled, its response byte will depend on the status of the internal data buffer. If the buffer is empty, a 41 hex will be returned as the status byte.

    0.5 µsec. 19-30 Twisted-pair ground return lines for signals on pins 1-10. INIT* Asserted when the GPIB-PRL receives either a universal device clear (DCL) or its listen address and a selected device clear (SDC). This signal will be asserted for approximately 100 µsec.

    IFC* and to send the device clear command. Upon power-on, the GPIB-PRL will read the status of the configuration switches and initialize the system. If switch 3 is OFF, the GPIB-PRL will be the System Controller and will assert IFC* for 500 µsec. The action of asserting IFC* for at least 100 µsec initializes the GPIB and makes the...
  • Page 31 Chapter 3 Technical Information If switch 2 is ON and switch 3 is OFF, the GPIB-PRL will not send out a listen address but will be the System Controller and will assert IFC*. This mode can be used if the GPIB-PRL is connected to a listen-only device which does not require addressing.

  • Page 32: P Mode Parallel Interface

    Direction Description STROBE* The STROBE* pulse tells the GPIB-PRL that the data on the bus is valid. The GPIB-PRL will read the data in on the rising edge of STROBE*. The STROBE* signal should be asserted for at least 0.5 µsec.

  • Page 33: Figure 3-2. P Mode Parallel Interface Timing

    Direction Description INIT* When this signal is asserted, the GPIB-PRL will be reset to its power- up state and its internal buffer is cleared. The DCL or SDL command will be sent to the GPIB device. INIT* should be asserted for a minimum of 50 µsec.
