The following sections describe the factory configuration settings and present alternate configurations. Figure 2-1 shows the location of the GPIB-VXI/C configurable components and their physical location relative to some of the major circuit components.
  • Page 21 Chapter 2 Configuration and Startup Procedures The GPIB-VXI/C is housed in a metal enclosure that has cutouts for access Note to all switches and jumpers associated with Slot 0/Non-Slot 0 settings, start-up mode, and Shared RAM settings. Under normal circumstances, you do not need to open the enclosure.

  • Page 26: External Input Termination

    External Input Termination Switches S12 and S16 enable a 50-ohm termination to ground for the external trigger and external clock inputs, respectively. The GPIB-VXI/C is factory-configured with the termination disabled for both the external trigger and the external clock inputs. Figure 2-3 shows the settings required to enable or disable the termination on the external trigger.

  • Page 27: Eprom Configuration

    Configuration and Startup Procedures EPROM Configuration The amount of read-only memory (ROM) in the GPIB-VXI/C can vary from 512 KB to 1 MB. The standard configuration consists of 512 KB of EPROM, which is used for the operating firmware. The GPIB-VXI/C also includes four sockets for EPROM expansion.

  • Page 28: Discrete Fault Indicator Configuration

    SYSFAIL* is asserted, pins 1 and 6 will present an electrical short-circuit. If S17 is in the ON position, the GPIB-VXI/C DFI is set to the normally closed mode. Therefore, if SYSFAIL* is not asserted while the backplane is powered-up, pins 1 and 6 will present an electrical short-circuit.

  • Page 29: Address Modifier Configuration

    A16 accesses, the lines AM5, AM4, and AM3 are needed high, low, and high, respectively, and AM1 is needed low. During A24 accesses, the lines AM5, AM4, and AM3 are all needed high. The GPIB-VXI/C drives the upper three address modifier lines appropriately for every access. You should configure the GPIB-VXI/C to drive the lower three address modifier lines as needed.

  • Page 30: Gpib-Vxi/C Startup Mode Configuration

    Figure 2-9. VXI System Startup Message Switch Settings Slot 0 Resource Manager Configuration You can configure the GPIB-VXI/C for Slot 0 Resource Manager operation by enabling the VXIbus Slot 0 functions and setting the logical address to 0, as shown in Table 2-7.

  • Page 33: Slot 0 Resource Manager Operation

    EXT CLK connector. Invalid. Do not use this setting. Slot 0 Resource Manager Operation At startup, a GPIB-VXI/C configured as a Slot 0 Resource Manager performs its self-tests, executes the RM functions, and then enters its normal mode of operation.

  • Page 34: Self-Test Operation

    SYSRESET* signal is negated. During this period, all of the VXIbus devices in the system should have completed their self-tests. Note You can configure the GPIB-VXI/C to wait for any number of seconds before RM operations begin. The RM then scans Logical Addresses 1 through 254 for static configuration devices (SC devices).
  • Page 35 The RM configures the VXI interrupter and interrupt handlers using a seven-entry table contained in nonvolatile configurations. During the VXI interrupt configuration, the RM assigns interrupt levels to all Programmable Handlers (PH) and Programmable Interrupters (PI). © National Instruments Corporation 2-17 GPIB-VXI/C User Manual...

  • Page 36: Static Configuration Operation

    However, if you want to customize your own DC hierarchy and the nonvolatile configuration specifies that the RM not finish configuring the hierarchy, the GPIB-VXI/C RM does not send Identify Commander or Begin Normal Operation to any devices, either static or dynamic.

  • Page 37: Gpib Address Assignment

    Servants. If the Message-Based device does not support minimal Word Serial[I] or VXIbus 488.2[I4] capabilities, no GPIB address link is created. The GPIB-VXI/C assigns a GPIB address to each device according to the top five bits of its logical address. For example, the GPIB address of a device with Logical Address 96 (01100000b) would be 12 (01100b).

  • Page 38: System Configuration Table

    Chapter 2 Configuration and Startup Procedures You can change the self-assigned default GPIB address of the GPIB-VXI/C through the nonvolatile memory configuration as described in the Change Configuration Information section of Chapter 4, Nonvolatile Configuration. The default GPIB address of the GPIB-VXI/C when configured for multiple secondary addresses is Secondary Address 0 (Primary Address 1).

    Message-Based operation. Refer to Table 2-12. Disable the VXIbus Slot 0 functions. Set the model code of the GPIB-VXI/C to be configured for Non-Slot 0 operation using the nonvolatile configuration mode. Set the logical address to a non-zero value with an appropriate Servant area size using the nonvolatile configuration mode or by using DIP switch SW1.

  • Page 40: Non-Slot 0 Message-Based Device Operation

    Configuration and Startup Procedures If the logical address is set to FFh in nonvolatile configuration (the DIP switch cannot set the logical address to FFh), the GPIB-VXI/C will participate in dynamic configuration. Otherwise, the GPIB-VXI/C is a static configuration device.

  • Page 41: Slot 0 Message-Based Device Configuration

    Refer to Table 2-14. Enable the VXIbus Slot 0 functions. Set the model code of the GPIB-VXI/C to be configured for Slot 0 operation using the nonvolatile configuration mode. Set the logical address to a non-zero value with an appropriate Servant area size.

    Servant area. When the GPIB-VXI/C responds to the Begin Normal Operation command, it enters the normal mode of operation. After the GPIB-VXI/C Passed bit is set, the RM can manipulate or read the MODID lines by sending the Word Serial queries Read MODID, Set Lower MODID, or Set Upper MODID to the GPIB-VXI/C.

  • Page 43: Local Command Set

    The GPIB-VXI/C command set consists of commands and queries. Commands cause the GPIB-VXI/C to take some action. A query may also cause the GPIB-VXI/C to take some action, but it also returns a response containing data or other information.

  • Page 44: Command Set Access

    • VXI Word Serial Communication All ports are active when the GPIB-VXI/C is in the Normal Operation substate and operate independently of one another. The GPIB-VXI/C returns query responses only to the port originating the query. The GPIB-VXI/C also maintains a separate status state for each port.

If your application currently uses absolute addressing and you do not want to convert to device-relative offsets, you may consider the MEMACC resource, which accepts absolute addressing.
  • Page 174 If you have more than one GPIB-VXI controller in your system, or if you change the primary address of a GPIB-VXI controller from its default (1 for the National Instruments GPIB-VXI/C), or if you have a GPIB-VXI controller from another vendor, then you need to configure NI-VISA to find such a controller.
  • Page 175 Code Instruments (CIs). Two CIs come standard in the firmware of the GPIB-VXI/C. The first CI is called the DMAmove CI and is used for dedicating one of the GPIB-VXI/C GPIB addresses for use as a high-speed memory port. The second CI is used for controlling one or more Colorado Data Systems (CDS) 73A-852 adapter modules.

This section explains how to use the ECIboot? nonvolatile configuration editor to permanently install an EPROMed Code Instrument. Enter the nonvolatile configuration mode as described in Chapter 4, Nonvolatile Configuration.
  • Page 177 For the CDS-852 adapter, configure as many CI base locations as there are 852 adapters to be controlled by the GPIB-VXI/C. For example, to control four 73A-852s, configure CI base locations 0 through 3. The addresses for the two CIs are as follows.

It can transfer 8- or 16-bit quantities from either source or destination (they can be different). It can increment or not increment addresses as it counts to give fast access to FIFO registers or block memory.
