Safety Summary
The following general safety precautions must be observed during all phases of operation, service, and repair
of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual
could result in personal injury or damage to the equipment.
The safety precautions listed below represent warnings of certain dangers of which Emerson is aware. You,
as the user of the product, should follow these warnings and all other safety precautions necessary for the
safe operation of the equipment in your operating environment.
Ground the Instrument.
To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground.
If the equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into
an approved three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an
electrical ground (safety ground) at the power outlet. The power jack and mating plug of the power cable meet
International Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or
fumes. Operation of any electrical equipment in such an environment could result in an explosion and cause
injury or damage.
Keep Away From Live Circuits Inside the Equipment.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other
qualified service personnel may remove equipment covers for internal subassembly or component
replacement or any internal adjustment. Service personnel should not replace components with power cable
connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To
avoid injuries, such personnel should always disconnect power and discharge circuits before touching
components.
Use Caution When Exposing or Handling a CRT.
Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To
prevent CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment.
Handling of a CRT should be done only by qualified service personnel using approved safety mask and
gloves.
Do Not Substitute Parts or Modify Equipment.
Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local
Emerson representative for service and repair to ensure that all safety features are maintained.
Observe Warnings in Manual.

ESD Precautions
ESD
Use ESD
Wrist Strap
Emerson strongly recommends that you use an antistatic wrist strap and a
conductive foam pad when installing or upgrading a system. Electronic
components, such as disk drives, computer boards, and memory modules, can be
extremely sensitive to electrostatic discharge (ESD). After removing the
component from its protective wrapper or from the system, place the component
flat on a grounded, static-free surface (and, in the case of a board, component side
up). Do not slide the component over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by
wearing an antistatic wrist strap (available at electronics stores) that is attached to
an active electrical ground. Note that a system chassis may not be grounded if it is
unplugged.

Introduction
This chapter describes the physical and electrical structure of the PMCspan. Figure 3-1 and
Figure 3-2 show the detailed block diagrams of the PMCspan and its primary interfaces.
PMC module I/O is available through the PMCspan front panel opening (for PMC modules with
front panel connectors) or through the PMCspan VMEbus P2 backplane connector.
PCI-to-PCI Bridge Chip
The primary component on the PMCspan is the PCI6150 PCI-to-PCI bridge chip. This device
provides the interface between the primary PCI bus (processor side), and the secondary PCI
bus, which provides the interface to the PMC module. The bridge chip connects to the VMEbus
processor module PCI bus through the PCI Expansion connector. The secondary PCI bus
connects to each of the PCM slots and a an optional secondary expansion connector. For a
detailed description of the PCI6150 chip, refer to the data book listed in Appendix A, Related
Documentation.
The PCI6150 PCI-to-PCI Bridge chip supports a 32-bit primary bus interface and a 32-bit
secondary bus interface. This chip provides full support for delayed transactions which enables
the buffering of memory read, I/O, and configuration transactions. It supports buffering of
simultaneous multiple posted write and delayed transactions in both directions.
The PCI6150 has clock and arbitration pins to support PCI bus masters on the secondary bus.
These are used to provide clocks an bus arbitration for the PMC module. The PCI6150 supports
concurrent operation on the primary and secondary PCI busses providing traffic isolation
between the primary and secondary busses.

PMCspan PMC Carrier Module Installation and Use (6806800A59B)
3 Functional Description
PMC Interface
Each PMC slot has three EIA E700 AAAB connectors for a 32-bit PMC interface to secondary
PCI bus and user specific I/O. The PMCspan VME backplane connector P2 provides 64 I/O
signals for PMC 1, and 46 P2 I/O signals for PMC 2. Refer to Chapter 5, Connectors, for the pin
signal assignments.
PCI Expansion
The PCI expansion interface is provided by a 114-pin plug connector (P4 or P5) on the
secondary side of the PMCspan. This mates to the PCI Expansion connector on the VME
processor module. Refer to Chapter Chapter 5, Connectors, for the pin signal assignments.
The IDSEL for the PCI6150 chip is connected to AD20 on the PMCspan. Therefore the PCI6150
Device Number on the primary PCI bus is 1_0100b.
Secondary Expansion
Secondary PCI bus expansion is provided by a 114-pin receptacle connector, J3, on the
primary side of the PMCspan16E-002. This mates to a 114-pin plug connector, P3, mounted
on the secondary side of the PMCspan26E-010. Refer to Chapter 5, Connectors for the pin
signal assignments.
Clock Configuration
The PCI6150 PCI-to-PCI Bridge chip will access the Clock Configuration logic following a
primary PCI bus reset. The PCI6150 will automatically enable the PCI clock for all four PMC
slots.
PMC Present Signals
The PMC PRESENT signal (BUSMODE1#) from each of the PMC modules (up to four) may be
read any time following a reset through the General Purpose I/O interface in the PCI6150. Refer
to PMC Present Signal Assignment on page 25.
Front Panel LEDs
There are two green LEDs located on the front panel of the PMCspan, one for each PMC
module. Both LEDs will be illuminated during reset. An individual LED will be illuminated
whenever a PMC module has been granted bus mastership of the secondary PCI bus.

PMC Performance
All PMCspan models support 32-bit PCI operations at 33 MHz on the PMC (secondary) side.
The PMCspan16E-002 primary carrier module supports 32-bit PCI operations on the processor
(primary) side. Refer to the PCI6150 data book, listed in Appendix A, Related Documentation
for PCI transaction timing information across the bridge.
Writes to the PCI bus are also posted by the Raven chip ASIC, so this section will focus mainly
on read cycles. The read access latency for PMCspan-bound cycles initiated by 60X bus master
consists of the following components:
Tstart
Start-up time (TS# to PCI bus Request).
Tstart is 6 system clocks.
Tarb
On-board PCI bus arbitration time.
Tac
On-board PCI access time (FRAME# to TRDY#).
Tlat
Latency through PCI-to-PCI bridge.
Tdelay
Delay time from TRDY# on PCI to TA# on 60X bus. Tdelay is 4 system clocks.
Table 3-1 shows the access timings for various types of transfers initiated by a 60X system bus
master to a PMCspan module.

PLX PCI6150 Configuration Registers
The PCI Configuration Registers for the PLX PCI6150 PCI-to-PCI Bridge chip are shown in
Table 4-1. For a detailed register bit description, refer to the PLX PC16150 data book listed in
Appendix A, Related Documentation.
Configuration Transactions
PCI configuration transactions are used to initialize the PCI system including the PCI-to-PCI
bridge and devices on the PMC module. All PCI6150 registers are accessible only in the
configuration space. In addition to accepting configuration transactions for initialization of its
own configuration registers, the PCI6150 also forwards configuration transactions bound for
devices on the PMC module, as well as special cycle generation on the secondary PCI bus.
These two types of configuration transactions are supported by Type 0 and Type 1 configuration
cycles.

Type 0 Configuration Cycles
Type 0 configuration cycles are issued to configure devices on the same bus as the initiator. The
processor will access configuration registers within the PCI6150, issuing a Type 0 cycle on the
primary PCI bus by programming the Raven CONADD Register for Bus Number 0, and Device
Number 1_0100 (binary). The Function Code is ignored by the PCI6150 since it is a singlefunction device. The RAVEN chip will translate this configuration address to an IDSEL# on
AD20, which is connected to the DEVSEL# on the PCI6150 on the PMCspan.
The PCI6150 limits all configuration register accesses to a single double word data transfer and
returns a target disconnect with the first data transfer if additional data phases are requested.
All bytes of the requested double word are returned, regardless of the PCI byte enable bits.
Type 0 configuration transactions do not use the PCI6150 data buffers so these transactions
are completed immediately regardless of the state of the data buffers.
The PCI6150 will ignore all Type 0 transactions initiated on the secondary PCI bus.
Type 1 Configuration Cycles
Type 1 configuration cycles are issued to configure PMC modules. The processor will access
configuration registers within the PMC modules by issuing a Type 1 cycle on the primary PCI
bus by programming the Raven CONADD Register for Bus Number $01 (i.e., the Bus Number
programmed into the Secondary Bus Number register), and the Device Number per Table 4-3.
The Function Code is dependent on the PMC modules.
The PCI6150 will perform a Type 1 to Type 0 translation when the Type 1 transaction generated
on the primary bus is intended for a PMC module on the secondary bus. The PMC module can
then respond to the Type 0 transaction.
22
PMCspan PMC Carrier Module Installation and Use (6806800A59B)

The PCI6150 forwards Type 1 to Type 0 configuration transactions as delayed transactions
which are limited to a single data transfer.

Special Cycles for PMC
Type 1 to Type 1 Forwarding
If the PCI6150 detects a Type 1 configuration transaction intended for a PCI bus downstream
from the secondary bus (such as another PCI bus on a PMC module), the PCI6150 will forward
the transaction unchanged to the secondary bus. This transaction will eventually get translated
to a Type 0 transaction or a Special Cycle by a downstream PCI-to-PCI bridge.
Special Cycles
Special cycle transactions generated on the primary PCI bus are ignored by the PCI6150.
However, Special Cycle commands can be sent to the PMC module using a Type 1
Configuration transaction. The PCI6150 will generate a Special Cycle on the secondary bus
when it detects a Type 1 transaction on the primary bus with the following conditions:
❏
The lower two primary address bits AD(1:0) are 01 (binary)
❏
The device number in AD(15:11) is 1_1111 (binary)
❏
The function number in AD(10:8) is 111 (binary)
❏
The register number in AD(7:2) is 00_0000 (binary)
❏
The bus number in AD(23:16) is $01 (the value in the Secondary Bus Number Register)
❏
The bus command on C/BE# is a configuration write command
PMCspan PMC Carrier Module Installation and Use (6806800A59B)
23
4 Programming Model
The PCI6150 translates the Type 1 Configuration command to a Special Cycle and forwards the
address and data unchanged. The transaction is forwarded as a delayed transaction but the
target response is not forwarded back because Special Cycles result in a master abort. If more
than one data transfer is requested during a Special Cycle, the PCI6150 responds with a target
disconnect during the first data phase.

PMC Present Signal Assignment
The PMCspan hardwires the BUSMODE(4:2)# encoding signals to 001 (binary) for each PMC
slot indicating that the PMCspan supports PCI protocol. The signal BUSMODE1# returned from
each PMC module indicates there is a PMC module installed in the slot and that the PMC
module supports PCI protocol. The PMC Present signals from each PMC slot may be read at
any time following a reset on the PCI6150 GPIO pins. Table 4-6 shows the assignment of the
PMC Present signals to the GPIO pins. Figure 4-7 shows the values in the Serial Clock Mask
register following a reset. Serial Clock Mask bit 13 is 0 in order to enable s_clk_o(9) for the 6150
s_clk input.

Introduction
The PMCspan module connectors provide I/O and for interfaces to the VME processor modules
and to other PMCspan modules. The pin assignments for the connectors PMCspan
connections are provided in the following sections.
VMEbus Connectors (P1/P2)
The VMEbus P1 connector is a partially populated version of the 96-pin DIN type connector.
The P1 Connector contains 23 pins and is used to provide +5V power to the PMCspan module.
IACK and Bus Grant signals are passed through as required by the VME specification. The P2
VMEbus connector is a 5-row 160-pin connector and provides P2 I/O for the PMC modules.
The pin assignments for P1 and P2 are shown in Table 5-1 and 5.2.

PMC Slot Connectors (J11/J12/J14) (J21/J22/J24)
Each PMC slot has a set of three 64-pin connectors (EIA E700 AAAB) for connection to the 32bit secondary PCI bus and for PMC I/O. The PMC Slot 1 connectors are as J11, J12 and J14;
the PMC Slot 2 connectors are J21, J22 and J24.
All 64 I/O signals from PMC 1 (J14) are routed to P2, while only the first 46 I/O signals of PMC
2 (J24) are routed to P2. The pin assignments for these connectors are shown in the following
tables.
