  • Page 8: Getting Started

    µ EPC-2 HARDWARE REFERENCE Page Page Getting Started This manual contains all the information you need to install and use the EPC-2 VXIbus embedded computer. Additional user's and programmer's manuals discuss the use of the EPConnect software package normally provided with EPC-2.

  • Page 9: Installation

    VXIbus slot-0 functions (generation of the 10 MHz ECL .i.CLK10; signals and control of the .i.MODID; module identification function). To configure the EPC-2 as the slot-0 controller or not, there are two things you need to do: ù...

  • Page 10: Troubleshooting The Configuration Jumpers

    You can do this at the operating-system prompt or when the power-on selftest screen is cleared after rebooting. Older Models To change the configuration of the earlier version of the EPC-2, open the right cover and set the unit on a static-free surface with the front panel to the left.

  • Page 11: Exm Module Insertion

    Align the EPC-2 to two adjacent top and bottom card guides in the VXI chassis. Slide the EPC-2 module into the chassis. Use firm pressure on the handles to mate the module with the backplane connectors. Tighten the screws in the top and bottom of the front panel to ensure proper connector mating and prevent loosening of the module via vibration.
  • Page 12 (multifrequency or "multisync") monitors. If you cannot mate your monitor to the EPC-2 because you have a cable with a 9-pin connector, either (1) you have a TTL monitor that is not compatible with VGA or (2) you have a multisync monitor (which are usually shipped with 9- and 15-pin cables or adapters) and are using the wrong cable.
  • Page 13 The .i.GPIB port; is a standard shielded IEEE-488 receptacle. External Clock Input The EPC-2 provides the option, when it is configured as the slot-0 controller, of deriving the ECL .i.CLK10; signal from an internal oscillator or from a 10 MHz .i.external clock; source.

  • Page 14: Operation

    BIOS setup program and following its instructions for reset, and power-off/power-on. The reset switch performs a hardware reset of the EPC-2 and invokes the BIOS initial- ization routine, which performs a selftest of the hardware, initializes the EPC-2 hard- ware, locates the disk drives, and tries to boot an operating system.

  • Page 15: Front Panel Indicators

    (2) a VXIbus access is being attempted but the EPC-2 has not received a bus-grant signal. In the latter case, the usual rea- sons are an error in setting the jumpers on the VXIbus backplane, not being fully seated in the backplane, or a failure in the slot-0 system controller mod- ule.
  • Page 16 SCSI BIOS. For a 4 MB EPC-2 system, expect to see "3072K FOUND" for expansion memory. For an 8 MB EPC-2 system, expect to see "7168K FOUND" for expansion memory. For 16 MB, you should see "15360K FOUND."...

  • Page 17: Bios Setup Screen

    This occurs if the BIOS is expecting to find a bootable AT (IDE) disk drive, but the drive is not present or has failed. Ensure that the EPC-2 is firmly seated in the back- plane and that both 5V and 12V are available to the EPC-2.
  • Page 18 ID OB1 OB2 Slot 0 Some earlier models of the EPC-2 do not have the separate fixed disk menu; the disk options are on the initial setup screen. Use the up and down cursor (arrow) keys to move from field to field. For most fields, once you are positioned at the field, pressing the left and right cursor (arrow) keys will rotate through the available choices.
  • Page 19 This field gives you several choices about the type of floppy disk drives installed as the A and B drives. Since the EPC-2 has a single 3.5" 1.44 MB floppy disk drive, the only correct setting of these parameters is that shown above.
  • Page 20 RONR (request on no request, also known as the VXI fair-requester mode). ROR results in slightly better EPC-2 performance when accessing the VXIbus; RONR directs the EPC-2 to not "park" on the bus and thus slightly improves the access time of other VXIbus masters to the bus.

  • Page 21: Exm Configuration

    1. If an interrupt is needed, use only IRQ3. 2. Do not use any DMA channels. 3. Do not select I/O addresses that conflict with those in the EPC-2. A com- plete list appears in Chapter 4. For instance, I/O addresses in the 300-377 range can be used.

  • Page 22: Disk Formatting

    EPC-2 HARDWARE REFERENCE Disk Formatting The hard disk in the EPC-2 is shipped from the factory low-level formatted with the proper interleave factor. Depending on the context in which you ordered the EPC-2, the disk is either bootable (containing an operating system and other software pre-installed) or empty and not high-level formatted.
  • Page 23 DOS. If you are asked for drive parameters, they depend on the type of disk installed in your EPC-2. Some representative drives are specified in the following table. If your EPC-2 has another type of SCSI drive, call customer service for assistance.

  • Page 24: Programming Interface

    Hardware features in common with standard PCs should be accessed by standard BIOS calls. Hardware unique to EPC-2, such as the VXIbus interface should be accessed through the .i.EPConnect; .i.Bus Manager;, an easy-to-use, high-level interface that frees you from most machine-dependent considerations.

  • Page 39 A16/A32 address spaces with the manufacturer being Radix MicroSystems (.i.manufacturer code; 4076). Since the EPC-2 is a .i.DC device; (a device without a static ULA, but a ULA that can be assigned dynamically by the .i.resource manager;), an initial write into this register from the VXIbus assigns a ULA to the EPC-2.
  • Page 40 8146 SLAVE BASE 8147 If SLE is set, the value in port 8147 defines the base address of the EPC-2's memory in the VXIbus A32 address space. This register can hold the values 18- 1F, which correspond to the base addresses 18000000-1F000000.
  • Page 41 If 0, the message register has been .i.lock;ed. WRCP This EPC-2 specific bit is a read-only copy of the WRDY bit. FSIG Defined only when SIG=1, in which case FSIG is the number (0 or 1) of the register in the FIFO holding the earliest signal.
  • Page 42 IACK 8151 .i.VMEbus address modifier;.i.address modifier;This register is also used when the EPC-2 makes an access through its .i.E page; to the VXIbus. Bits 7 and 6 provide VXI address bits A23 and A22, respectively. Bits 3-0 define the value placed on the associated VXI address-modifier lines.
  • Page 43 MODID signals on the VXI backplane. The bits named MO00-MO12 are associated with signals MODID00-MODID12. When a write occurs to BMOH, the EPC-2 drives the MODID signals on the back- plane. A read of BMOH terminates the driving of the signals; the value returned from this "driver-terminating"...
  • Page 44 .i.BES; register after each access, or enable the BERR event to generate an interrupt.) BSAM This bit is 0 if a pipelined write is active from the EPC-2 onto the VXI data-transfer bus. It allows software to wait for the completion of a write (e.g., to determine when SBER can safely be examined after a series of writes).

  • Page 45: Vmebus Accesses

    If the FIFO is empty, the value returned is not specified. Register State after Reset A .i.hardware reset; of the EPC-2 (not a keyboard CTRL+ALT+DEL reset) clears all of the register bits to 0 (except those defined as a constant 1). The EPC-2's BIOS, however, initializes some of the registers based on information from the setup screen and elsewhere.

  • Page 47: Slave Accesses From The Vmebus

    All of these instructions perform a read followed by a write. When such a read occurs that is mapped to the VXIbus, the EPC-2 treats it as the start of a VXI RMW cycle. The next VME access from the 386 is treated as the write that terminates the RMW cycle.

  • Page 48: Vxibus Interrupt Acknowledgement

    EPC-2 can access the global memory with the same addresses as used by other processors without needing to understand that the memory is actually on- board. This ability is also useful in system checkout (i.e., checking operation of the backplane) and in giving an EPC-2 program the ability to view its memory in .i.big endian;...
  • Page 49 A16/A32 address spaces with the manufacturer being RadiSys Corporation (manu- facturer code 4076). Since the EPC-2 is a DC device (a device without a static ULA, but a ULA that can be assigned dynamically by the resource manager), an initial write into this register from the VXIbus assigns a ULA to the EPC-2.

    Only having another module clear RSTP or assert the VXI .i.SYSRESET; line, or doing a power off/on cycle (allowing 10 seconds or more in the off state to avoid damage to the disk drive) will remove the EPC-2 from this soft reset state.
