    Chapter 1 – Introduction Chapter 1 - Introduction Overview The XVME-976 adapter module provides I/O expansion for Xycom’s XVME-654 and XVME-655 VMEbus PC/AT processor modules. Direct connection is possible with the XVME-654. Connections with the XVME- 655 require a transition board, such as the XVME-978/1 Ethernet card, or XVME-978/100 transition module, which plug into the XVME-655 and pro- vide the mechanical and electrical connections for the XVME-976.

The SSP is ideal for embedded applications, where low power consumption, small space, high reliability, and IBM PC or PC/AT software and serial/parallel port compatibility are required.

  • Page 28: Jumper Settings

    Chapter 2 – SSP Installation (XVME-956/400) Jumper Settings This section describes how to set the jumpers on the SSP board. On a 14-pin jumper group, notations such as "1/2" or "7/8" will be used to indicate that you should install a shorting block or wire between pins 1 and 2 or between pins 7 and 8.
  • Page 29 Usually, the SSP will be used in addition to the XVME PC/AT serial and parallel ports. Hence, Xycom recommends COM A be set to I/O port 03E8, (see Table 2-4), COM B to 02E8 and the parallel port to 0278, (see Table 2-7).

  • Page 30: Interrupt Selection

    Chapter 2 – SSP Installation (XVME-956/400) Interrupt Selection Each port can be assigned to an interrupt in the range IRQ2 - IRQ7. Within this range, there are no restrictions on the choice of interrupts, and the inter- rupt assignments must be unique. Table 2-8 lists some commonly used I/O port interrupts.

  • Page 31: Serial Port Configuration And Connection

    XVME-976 Adapter Module Serial Port Configuration and Connection The RS-232C port at J2 COMB requires configuration beyond the choice of I/O base address and interrupt described in the previous sections. The serial port at J2 can be configured to operate as a RS-232C or RS-485 port. Jump- ers W11 - W14 and W18 - W19 determine the functions of individual inter- face lines on connector J2.

  • Page 32: Rs-232C Usage - Com A And Com B

    Chapter 2 – SSP Installation (XVME-956/400) RS-232C Usage - COM A and COM B Table 2-13 lists the connector pin assignments for the RS-232C port at J1. The entries in this table will also apply to the serial port at J2, if it is config- ured as an RS-232C port, in accordance with Tables 2-3 and 2-11.
  • Page 33 XVME-976 Adapter Module Instead, RS-485 uses AUXIN and AUXOUT. For maximum software com- patibility, the RS-232C Clear to Send (CTS) handshake input signal for the serial controller is derived from the RS-485 AUXIN signal. Similarly, the RS-485 AUXOUT signal is derived from the RS-232C Request to Send (RTS) handshake output signal from the serial controller.

  • Page 34: Parallel Port Configuration And Connection

    Chapter 2 – SSP Installation (XVME-956/400) mode. It is the responsibility of the user's software to provide a protocol that can handle the bi-directional nature of the interface. The four handshake in- put signals (RI, CTS, DSR, and DCD) are tied active by the jumpers in- stalled at W11, W12, W13, and W14 when this port is configured for RS- 485 (refer to Tables 2-10 and 2-11).

  • Page 35: Specifications

    XVME-976 Adapter Module Beyond the choice of I/O base address and interrupt described in the previ- ous sections, there is only one jumper that affects the parallel port at J3. This is W20, which controls whether the parallel port will function as a standard PC/AT printer port (output only) or as a bidirectional data port.

    XVME-976 Adapter Module Driver Operation This section describes operation with the module's drivers. Also covered are the utility programs, driver installation, formatting and partitioning of the drives. Utility Programs Utility programs were shipped with the module on a diskette. There are two files in the root directory and five in a subdirectory named AFDISK.

Module Switch Configuration There are two switch banks on the module which the BIOS reads to config- ure the SCSI interface, (refer to Tables 3-1, and 3-2).
  • Page 43 XVME-976 Adapter Module Disconnect - When this option is enabled, SCSI targets are allowed to disconnect from the module if there is a long duration of time for com- pleting the operation requested. They reconnect later when finished. If disconnection occurs, the module will issue INT 15 (busy, wait for disk drive) to allow the host CPU using other software to multi-task.

    Chapter 5 - 16-Bit Ethernet Installation SHOW4I29 This utility program displays some of the current XVME-956/411 setup parameters. The COMPATIBLE option and the PROMLOC option are not readable, so they are not displayed. SHOW4I29 is invoked with the hexadecimal port address on the command line: SHOW4I29 300 Because it is possible to forget the port location of a XVME-956/411 card, the port...
