Unpacking and Special Handling Instructions
This PEP product is carefully designed for a long and fault-free life; nonetheless, its life expectancy can be drastically
reduced by improper treatment during unpacking and installation.
Observe standard anti-static precautions when changing piggybacks, ROM devices, jumper settings etc. If the product
contains batteries for RTC or memory back-up, ensure that the board is not placed on conductive surfaces, including
anti-static plastics or sponges. These can cause shorts and damage to the batteries or tracks on the board.
When installing piggybacks, switch off the power mains.
Furthermore, do not exceed the specified operational temperature ranges of the board version ordered. If batteries are
present, their temperature restrictions must be taken into account.
Keep all the original packaging material for future storage or warranty shipments. If it is necessary to store or ship the
board, re-pack it as it was originally packed.

1.1 Product Overview
PEP’sVM162/172 combines high computational performance and flexible I/O requirements through its
twin IndustryPack and single CXC interface with excellent communication ability afforded by the Mo-
torola ‘QUICC’controller.
A combination of high-performance CPUs (Motorola MC68040/MC68060) and the Quad Integrated
Communications Controller chip, the Motorola MC68EN360,‘QUICC’not only enable computational
performances from approximately 35 MIPs to over 100 MIPs, but dispense with the usual restrictions
associated with serial communication.
Application-specific tailoring is assured through versatile interface options which, together with PEP’s
CXC interface, makes this 6UVMEbus CPU ideally suited for communication and automation applica-
tions.With up to 6 serial interfaces resident within the same realestate and support for standard LAN or
WAN interfaces provided, communicational versatility is guaranteed.
Two on-board EPROM sockets are designed to accommodated ROMed applications and/or the PEPbug
debug monitor.The VM162/172 is supplied with these sockets empty and the PEPbug programmed into
the FLASH memory residing on one of the DM6xx memory piggybacks.
The PEP VM162/172 Board Support Package is available for several popular real-time operating sy-
stems: OS-9, VxWorks,VRTX/OS and pSOS+.
1.2 IndustryPack Flexibility
Fully integrated within theVM162/172 CPU boards are two IndustryPack carrier interfaces. Each inter-
face accesses an 8/16-bit databus and supports IP class 1 modules.
The IP concept is based on an open specification allowing vendors to fabricate an independent library
of digital, analog, communication or counter mezzanine plug-in modules for example that are compati-
ble with carrier boards from manufacturers like PEP. With a few hundred such mezzanines currently
available, users can easily find the appropriate interface to a wide variety of industrial requirements.
In accordance with the IP specification, PEP has implemented an 8/16-bit data width interface operating
at 8 or 32MHz that supports interrupts and communicates with the host carrier via a 50-pin connector
with embedded address, data, control and power lines.This caters for more than 90% of the available IP
modules which do not have DMA support.
• Up to 2 standard or 1 2x-sized IP
• Supports I/O, ID, memory & IRQ
• Supports 8/16-bit IP cycles
• Prog. IP bus speed (8/32 MHz)/IP
• 2 interrupts per IP
• 2 8 MB linear memory space/IP
• Overload protection (fuses)/IP

1.3 Controller eXtension Connector
Although the VM162/172 adds a new dimension to computer architecture with its direct IndustryPack
interface, it is also a continuation of the successful range of PEP’s CPU boards with communication pro-
cessors and CXC capability. The CXC extends the already abundant industrial I/O capability of the CPU
and also allows custom design according to the guidelines laid-down in the CXC specification.
Introduced in 1990, PEP’s Controller eXtension Connector (CXC) concept enables a mezzanine Input/
Output extension on theVME or on distributed Input/Output systems based on CXC as a backplane bus.
The CXC is based on an open specification allowing unprecedented flexibility in meeting customer re-
quirements.
PEP has named these mezzanine plug-in modules Controller eXtension Modules (CXM). These 96-pin
CXMs are designed to operate with CXC based host modules which includes the VM162/172.
Designed primarily to operate in harsh industrial environments, this versatile modularity provides not
only a cost-effective engineering solution but also allows customers a near exhaustive selection of sy-
stem configurations through a selection of over 30 base CXMs providing analog, digital and other I/O
extensions such as SCSI and fieldbus connection (PROFIBUS, CAN, LON and Bitbus). Hence, a fea-
ture of the VM162/172 is that the ‘raw’serial signals from the ‘QUICC’SCC2, SCC3 and SCC4 chan-
nels being internally wired to the front panel as well as to the CXC interface.
Network interfacing is provided if required by ordering the relevant front-panel which comes complete
with the appropriate SI6-piggyback, serial port connectors and 50-pin D-Sub IndustryPack connector.
Naturally, to cater for those customers who merely wish to take advantage of the computing power and
CXC capablility that the VM162 offers, blank front-panels without the networking options have been
devised.
1.4 Front Panel and I/O Configuration
The illustrated front-panels show the possible connections of the SCC1 communications channel for
Ethernet, RS485 or blank. In addition, the front panels are available with mini-D-Sub connectors instead
of RJ45 connectors for the 4 standard serial channels.
The 50-pin, subminiature SCSI 2 style D-Sub connectors for emerging IP signals offer improved EMI
protection (compared with the on-board flat cable connector.) Each IP module has its own shielded con-
nector for state-of-the-art industrial cabling.
All front-panels feature a user, watch-dog and halt status LED, reset and abort button switches and
where possible, the status of the Ethernet communication.

1.5 Features
CPU Options
The 68060 processor operating at 50 Mhz provides the highest performance while the 68040(V) at 33
MHz sets the standard in the Motorola CISC portfolio.
68EN360
The ‘QUICC’chip operates as an I/O and communication companion providing 4, high-speed serial
channels, timers, clocks and Time Slot Assignment (TSA).
Serial Channels
All high-speed SCC channels are equipped with hardware hand-shaking and are available for a variety
of applications. SCC1 can be configured for either ethernet or RS485 (e.g. PROFIBUS) use by fitting
the appropriate SI6 piggyback. SCC2 - SCC4 are configured by default for RS232 operation and can be
changed to optoisolated RS232/485 as required by fitting the SC piggyback.An SMC1 interface provi-
des a simple RS232 connection for console/debug operations.
Figure 1.2 MC68EN360 ChannelAssignment
CXC Interface
The 96-pin interface allows other I/O possibilities to be realised by utilising PEP’s plug-in cards such as
the CXM-PFB12, CXM-CAN, CXM-LON, CXM-SCSI or CXM-SIO3..
Ethernet Interface
Three different SI6 piggybacks complete with all the associated control logic are available providing
10Base2, 10Base5 or 10BaseT interfaces.

IndustryPack
Any two IndustryPacks from a wide-range may be fitted to cater for the needs of digital, analog, com-
munication or counter functions. PEP also offers customers a non-gratis service that integrates the cho-
sen IP module and RT-OS with the VM162/172 carrier board.
SC-Interface
Three RS232 SC-Piggybacks are fitted as standard for serial communication.These can be replaced by
optoisolated RS232 or RS485 piggybacks as required.
DMA Channels
2 independent channels are provided by the ‘QUICC’chip for use by applications requiring DMA trans-
fer between VMEbus, CXC-modules, DRAM,FLASH memory and dual-ported SRAM.
DRAM/FLASH
This memory, complete with a 32 bit-wide access bus is placed on a piggyback with addressing capabi-
lity for up to two memory banks of 64 MByte each.The on-board programmable FLASH memory al-
lows the user to produce low cost upgrades by over-writing existing stored data and may also be
configured as a boot device.
SRAM
This is a dual-ported battery-backed (Goldcap) memory area with a 16 bit- wide access bus. Users of the
VMEbus and CPU both have access to this memory.
EEPROM
A 2 kbit EEPROM is provided on-board, 1 kbit has been pre-programmed with PEP production data lea-
ving the remaining available space for user application code.
