1. Overview
1.1 Block Circuit Diagram
Figure 1: Block circuit diagram of VME-PMC-CADDY/2
1.2 General
The VMEbus unit VME-PMC-CADDY/2 is a VME64-base board which can carry up to two PMC
modules of normal size. For the VMEbus connection the VME-PCI bridge Tsi148 by Tundra is used.
The Tsi148 is designed in a waythat the board can either operate as slave or as master on the VMEbus.
If the board operates as master, it supports a 4-level arbiter.
The VMEbus interrupt can be applied to any of the seven interrupt-request lines. The VME-PMC-
CADDY/2 isconnectedtotheVMEbusbytwo160-pinVG-connectors(complementarytoDIN41612)
for VME64 systems.
An active VMEbus-interrupt request is indicated by a red LED and a VMEbus access onto the board
is indicated by a yellow LEDs in the front panel (not in Conduction Cooled version)
Both PMC slots are designed according to the standard IEEE Std 1386-2001 (except the standard I/O
pin routing). It is possible therefore to insert all PMC modules, that use 3.3 V signalling only.
In addition to the connectors for the PMC-address/data and control signals, every slot of the
VME-PMC-CADDY/2 has an I/O-connector which applies the I/O-signals of the PMC modules to
VMEbus connector P2.
Two different P2 pin assignments are available: In the standard configuration each P2-pin is only
connected to one I/O-pin of the PMC-modules acc. to VITA 35 (P4V2-64ac, P4V0-64).
In the option ‘-32P' the pin assignment is designed acc. to IEEE Std 1386-2001, Table 8. This pin

Overview
VME-PMC-CADDY/2
Hardware-Manual • Doc.-No.: V.1915.21 / Rev. 1.0 Page 7 of 43
assignment offers the connection of the two PMC-modules via P2, because several PMC-I/O-signals
are shorted at P2.
Thefrontpanelof theVME-PMC-CADDY/2has twocutoutsforthe frontpanelsofthePMCmodules.
A blank cover for unused slots is included in the price.
Example libraries for the initialization of the board in C source code for VxWorks is available for a fee
on a disk (MS-DOS format). Drivers for other operating systems are available on request. Please state
your operating system with the version number when you order.
1.3 Characteristics of the Available Hardware Options
Note: All options given below have to be specified when ordering. Theycan not be installed later. For
an overview of the possible combinations of the options see page 42.
1.3.1 Option “-32P2”: Changed I/O-Pin Routing on P2
The VME-PMC-CADDY/2 is currently available with two different I/O-pin assignments:
- In the Standard configuration each of the I/O-pins of the PMC slot 1 (J14) is connected to exactly
one pin of the VMEbus connector P2 (accordingto VITA 35 (P4V2-64ac)) and each ofthe I/O-pins
of the PMC slot 2 (J24) is connected with exactly one I/O-pin of the VMEbus connector P0
(according to VITA 35 (P4V0-64)) .
- In the VME-PMC-CADDY/2 with the option “-32P”the pins are assigned according to IEEE
Std.1386-2001, Table 8. In this option the I/O-signals of both PMC-slots are connected with the pin
rows a+c of the VME-connector P2:
The pins 33...64 of the PMC-connector J24 are connected in parallel to this also to the rows
a and c of the P2 connector. This leads to a double assignment of the pins a1..a16 and c1...c16
on P2. Furthermore by this both PMC slots are connected with each other via 32 of their I/O-
pins.
Advantage: Accessvia aStandard-VMEbus-P2-I/O-adaptertoeachthehalfofthe I/O-signals
of both PMC slots.
Disadvantage: YouhavetopayattentionthatyourchoiceofinsertedPMCmodules doesnot
lead to undesired interactions between the modules, due to the I/O-signal
connection between the slots!

1.3.2 Option “-T”: Extended Temperature Range
The VME-PMC-CADDY/2 with this option is designed for the operation in the extended temperature
range of -40 / C ...+85 / C.
1.3.3 Option: “-CC”: Conduction Cooled
TheVME-PMC-CADDY/2-CCisdesignedwithcoveringheatsinks forheatdissipationin conduction
cooled systems. The slots of the PMC modules are conduction cooled PMC modules.
As a result of the heat sinks the front panel and with it the 10-pin har-link
®
-connector with the serial
interfaces are not equipped. Furthermore the front panel LEDs are not equipped.
The conduction cooled version VME-PMC-CADDY/2-CC is designed for operation in the extended
temperature range from -40 / C ...+85 / C as the VME-PMC-CADDY/2-T version.
