1.0 INTRODUCTION
1.1 Overview
This document describes the use and setup for the VMETRO MIDAS-20 board and the
SCRAMNet+Network PMC card. The combination of the MIDAS-20 and the
SCRAMNet+PMC card enable the user to share data on the SCRAMNet real-time
network with other SCRAMNet Network cards on other host systems and allow DMA
transactions across the VMEbus.
1.2 Related Documentation
The user should be familiar with the VMETRO MIDAS-20 User’s Guide and the
Systran SCRAMNet+ Network PMC Hardware Reference Manual (D-T-MR-
PMC###). These two manuals provide the necessary information to use each of these
products. This manual provides a minimal set of information from both manuals for
easier configuration. In addition the Universe User Manual from Tundra Semiconductor
Corporation gives a detailed description of the Universe Register Set.

2.1 Overview
The SCRAMNet Network PMC board and the VMETRO MIDAS-20 board provide high
DMA transfer rates between the VMEbus and the host computer system memory. The
VMETRO MIDAS-20 embeds the Universe VMEbus interface chip which supplies a
reliable high performance VMEbus to PCI bus interface in one device. The MIDAS-20 is
a PMC carrier for the VMEbus and contains two PMC card slots with slot 1 as the
default card slot for the SCRAMNet board (see Figure 2-1).

2.2 MIDAS-20 Board Settings
The Universe chip has a number of configuration registers to be initialized by the host
processor. Prior to the host initialization, the switch jumpers on the MIDAS-20 card must
be configured to define the operation of the card.

The switch and jumpers on the MIDAS-20 board determine the board options and the
memory addresses in the VME space. These settings must be configured correctly so
there is no overlap of address space for any other boards on the VMEbus. The VME
RegisterAccess Image (VRAI) determines the address of the Universe registers. The
Universe registers can then be programmed to provide access to SCRAMNet PCI
configuration registers. Table 2-1 shows the important VME addresses after the Universe
and V3 register sets have been set up (Section 4.0).

Table 2-2 contains the recommended switch and jumper settings on the MIDAS-20 using
VME register access image address sizeA32.

2.3 Register Configuration
For any transfers to the SCRAMNet PMC adapter, the Universe VME interface acts as a
VMEbus Slave and the PCI interface acts as a PCI Master. In this example, the Universe
register set is mapped to A32 at 14000000 hex (14 hex is set on the VRAI Base Address
DIP switch). The VME Slave Images in the Universe register set are configured to
provide access to SCRAMNet PCI configuration space (V3 registers). Next, the V3
register set is accessed and configured (VME address 1400a800 hex for PMC Slot #1 in
this example) to allow access to SCRAMNet memory and CSRs.
2.4 SCRAMNet+Card Settings
All examples assume that the SCRAMNet+card’s memory is accessed at VME address
14010000 hex. The SCRAMNet+CSR VME address is at 14810000 hex. The
SCRAMNet PMC card’s CSRs are always at an 800000 hex (8 MB) offset from the
SCRAMNet memory base address. Both SCRAMNet memory and SCRAMNet CSRs
generally reside in the same VME address space.
The VME A32 space is used in these examples for both SCRAMNet memory and CSRs.

2.5 Unique Node ID
Most applications require each SCRAMNet Node in a ring to have a unique node ID.
The SCRAMNet EEPROM can be programmed (CSR3 and CSR4) to ensure that each
node will have a unique node ID upon power-up. In addition, the SCRAMNet Utilities
Software package allows the node ID to be set in the scrcfg.dat file or in scrhwd.h if the
NO_CONFIG option is used. See the SCRAMNet Software Installation Manual for
details.
