INTRODUCTION
1.1 OVERVIEW
The XVME-202 PAMUX Interface Module is a single high, VMEbus compatible board
which allows a VMEbus master to communicate with a PAMUX I/O subsystem. The
specific features of the XVME-202 Interface Module are listed below:
Directly compatible with PAMUX I/O system.
16 PAMUX units can be addressed from one module providing up to
5 12 I/O points.
Termination resistors provided on board.
Connection is made via a 50 conductor ribbon cable.
Cable length can be up to 500 feet.
The XVME-202
module address occupies a
1K block of the VMEbus short I/O Address Space. The
decode logic allows the user to select (via 6 jumpers) any one of 64
of the 1K boundaries in the short I/O Address Space to be used as the module base
address. The module’s Internal Registers are accessible at specific addresses offset
from the selected module base address.
1.2 MANUAL STRUCTURE

specification and operation into three distinct areas. The three chapters develop
these aspects in the following progression:
Chapter One - A general description of the XVME-202 PAMUX Interface
Module, including complete functional and environmental specifications, VME bus
compliance information, and a block diagram.
Chapter Two - Module installation information covering module specific system
requirements, jumpers, and connector pinouts.
Chapter Three - Details covering functional addressing, and programming
considerations.
The Appendices are designed to provide additional information in terms of the
backplane signal/pin descriptions, a block diagram and assembly drawing, and module
schematics.

prior to installation in a VMEbus backplane. Included in this chapter is information
on module base address selection jumpers, address modifier jumper, connector
pinouts, and a brief outline of the physical installation procedure.
2.2 SYSTEM REQUIREMENTS
The XVME-202 PAMUX Interface Module is a single high VMEbus compatible
module. To operate, it must be properly installed in a VMEbus backplane.
The minimum system requirements for the operation of an XVME-202 PAMUX
Interface Module are one of the following:
A)
- A host processor properly installed on the same backplane.
A properly installed system controller module which provides the
following functions:
-- Data Transfer Bus Arbiter
--
System Clock driver
--
System Reset driver
-- Bus time-out module
An example of such a controller subsystem is the XYCOM XVME-010 System
Resource Module (SRM).
B)
l A host processor which incorporates the system controller functions
on-board.
An example of such a processor is the XVME-600 or the XVME-601.
Prior to installing the XVME-202 PAMUX Interface Module, it will be necessary to
configure three jumper options. These options are:
1)

2.4.2 Address Modifier Jumper
The XVME-202 has one jumper that determines which Address Modifier Codes it will
respond to. This jumper is labeled as
J2 (see Figure 2-1 for the jumper location).
Jumper
J2 determines whether the module will respond to supervisory or to non-
privileged short I/O VMEbus cycles. When jumper J2 is in, the module will respond
to supervisory short I/O bus cycles only. When jumper
J2 is out, the module will
respond to both non-privileged and supervisory short I/O bus cycles. Table 2-3
shows the relationship between jumper J2 and the Address Modifiers.

2.6 MODULE INSTALLATION
to logic
XYCOM VME modules are designed to comply with all physical and electrical
VMEbus backplane specifications. The XVME-202 PAMUX Interface Module is a
single-high, single-wide VMEbus module, and as such, only requires the P1
backplane.
2-6

XVME-202 Manual
December, 1986
CAUTION
Never attempt to install or remove any boards
before turning off the power to the bus, and all
related external power supplies.
Prior to installing a module, you should determine
and verify all relevant jumper configurations, and
all connections to external devices or power supplies.
(Please check the jumper configuration against the
diagrams and lists in this manual.)
To install a board in the cardcage, perform the following steps:
1)
Make certain that the particular cardcage slot which you are going to use
is clear and accessible.
2)
Center the board on the plastic guides in the slot so that the handle on
the front panel is towards the bottom of the cardcage.
3)
Push the card slowly toward the rear of the chassis until the connectors
engage (the card should slide freely in the plastic guides).
4)
Apply straight-f orward pressure to
of the module until the connector is fully engaged and properly seated.
the handle located on the front panel
NOTE
It should not be necessary to use excessive pressure
or force to engage the connectors. If the board does
not properly connect with the backplane, remove the
module and inspect all connectors and guide slots for
possible damage or obstructions.
5)
Once the board is properly seated, it should be secured to the chassis by
tightening the two machine screws at the extreme top and bottom of the
board.
2.7 CONNECTING THE PAMUX UNIT
On the PAMUX connector there is a notch indicating where pin 1is located (refer
to Figure 2-2). On XYCOM’s XVME-202 PAMUX Interface Adapter the ribbon
connector has a similar notch indicating the position of pin 1.
2-7

XVME-202 Manual
December, 1986
To connect a PAMUX (or a string of PAMUXs), plug one end of a flat ribbon cable
into the XVME-202 JKl connector so Pin 1 on the XVME-202 JKl is connected to
Pin 1 of the PAMUX connector (refer to Figure 2-2).
It is possible to connect 16 PAMUX Units in a daisy chain to the XVME-202 (see
Figure 2-3) as long as the total length of the ribbon does not exceed 500 feet.
2.8 OPTIONAL ON-BOARD OSCILLATOR
Jumper Jl is used to select between the VMEbus signal SYSCLK or an optional 16
MHz oscillator. Position JIB selects the VMEbus SYSCLK and is factory shipped in
this position. For systems where SYSCLK is not provided on the VMEbus
backplane, A 16 MHz oscillator, Ul9, can be installed and selecting Jl A, the module
will operate with its own clock.

Disconnect the module from the bus.
Remove the screw and plastic collar assemblies (labeled #6 and #7) from
the extreme top and bottom of the existing 3U front panel (#ll), and
install the screw assemblies in their corresponding locations on the 6U
front panel.
Slide the module identification plate (labeled #13) from the handle (#9) on
the 3U front panel. By removing the screw/nut found inside the handle,
the entire handle assembly will separate from the 3U front panel.
Remove the counter-sunk screw (#8) to separate the 3U front panel from
the printed circuit board (#12).
Line-up the plastic support brackets on the printed circuit board with the
corresponding holes in the 6U front panel (i.e. the holes at the top and
top-center of the panel). Install the counter-sunk screw (#8) in the hole
near the top center of the 6U panel, securing it to the lower support
bracket on the printed circuit board.
Install the handle assembly (which was taken from the 3U panel) at the
top of the 6U panel, using the screw and nut previously attached inside
the handle. After securing the top handle, slide the module identification
plate in place.
Finally, install the bottom handle (i.e. the handle that accompanies the
.
kit - labeled #2) using the screw and nut (#3 & #5) provided. Slide the
XYCOM VMEbus I.D. plate (#4) in place on the bottom handle. The
module is now ready to be re-installed in the backplane.

MODULE PROGRAMMING
3.1 INTRODUCTION
This chapter will briefly examine the addressing, and initialization procedures and
constraints required when programming the XVME-202 PAMUX Interface Adapter.
3.2 MODULE ADDRESSING
The XVME-202 is an odd byte only slave, and as such, the module will not respond
to even, single-byte accesses. However, word accesses may be used, with the
understanding that only the odd byte of the word is used to exchange PAMUX data.
The PAMUX data bus is only 8-bits wide, while the PAMUX unit contains 32 points
of I/O. To be able to access all 32 points, the PAMUX is composed of 4
consecutive banks of 8 I/O channels (refer to Figure 3-l). Refer to the OPTO 22,
PAMUX 4 32 Channel Data Acquisition/Control System manual for information about
how to assign each PAMUX unit a base address. With 16 PAMUX units connected
to the XVME-202, there will be a block of 64 consecutive 8-bit banks that could be
accessed.
