B5 – 3U VMEbus High-Speed Communication Controller
Due to its numerous serial interfaces and the powerful 68040V/68060 CPU, the B5
is optimized for high-speed communication control. All six serial lines of the 68360
are available: one Ethernet 10Base-T, two RS232 interfaces, two RS232, RS422,
RS485 or TTY interfaces via SA adapters (or optional second Ethernet) and one
ISO 9141-2 automotive interface. Two full/extended CAN interfaces complete the
B5's communication features.
The B5 supports full VMEbus master/slave functionality; it has abundant on-board
memory and an RTC.
Due to its local and global bus, genuine dual-ported DRAM and the shared
M-Module slot the B5 is also optimized for slave operation with all VME
communication features installed.
The B5 is able to run without VMEbus, being a real single-board computer with an
M-Module slot for flexible I/ O extension.
The B5 is an ideal solution for automotive applications, especially for small mobile
systems and harsh environmental conditions.

1.4 Installing an M-Module and SA Adapter
1.4.1 B5 Accessory Kit
To install an M-Module and/or SA adapter you need MEN’s B5 accessory kit (see
MEN’s website), which contains
• one 1-slot mounting board with an extra front panel for one M-Module and one
SA adapter
• one cover for the M-Module slot
• one cover for the SA adapter slot
• one 60-pin contact strip for the M-Module
• one ribbon cable for the SA adapter
• fastening material.
1.4.2 Installation
Note: MEN gives no warranty on functionality and reliability of the B5, M-Modules
and SA adapters used if you install M-Modules and/or SA adapters in a dif-
ferent way than described in this manual.
Perform the following steps to install an M-Module and/or an SA adapter:
Power-down your system and remove the B6 from the system.
M-Module
Install the M-Module on the mounting board with its component side facing the
board. The front connector extends through the front panel of the mounting
board.
Screw the M-Module to the mounting board using two countersink-head screws
and two flat-headed screws from the accessory kit (see figure below).

SA Adapter
Remove the two hexagonal-head bolts at the front of the SA-adapter connector.
Plug one of the ribbon cable connectors to the SA-adapter’s 10-pin plug con-
nector. Make sure that you match the pins correctly (cf. Figure 1, Map of the
Board - Front Panel and Top View, on page 13)!
Place the SA adapter on the mounting board with its component side facing the
board. The front connector extends through the front panel of the mounting
board.
Use the two hexagonal-head bolts removed from the front connector to screw
the SA adapter tightly to the front panel.
Plugging the Mounting Board on B5
Plug the 60-pin contact strip from the accessory kit carefully but firmly to the
M-Module connector of the B5.
Hold the mounting board parallelly over the B5 as shown in the figure below.
The ribbon cable of the SA adapter goes through the hole provided in the
mounting board.
Plug the 10-pin connector at the loose end of the SA-adapter ribbon cable to the
B5. Again, make sure that you match the pins correctly.
Be careful not to damage the 60-pin contact strip!
Align the 40-/60-pin connector of the M-Module with the 60-pin contact strip.
Note: Older M-Modules often have only 40-pin connectors. They are plugged to
rows A and B of the 60-pin connector of the B5 (cf. Figure 1, Map of the
Board - Front Panel and Top View, on page 13).
Press the contacts and M-Module connector carefully but firmly together.
Now insert the two boards into the enclosure.

2 Functional Description
The following describes the individual functions of the B5 and their configuration
on the board. There is no detailed description of the individual controller chips and
the CPUs. They can be obtained from the data sheets or data books of the
semiconductor manufacturer concerned (Chapter 5.1 Literature and WWW
Resources on page 64).
2.1 Power Supply
2.1.1 Connection of Supply Voltage
The B5 is supplied with +5V and +12V via the VMEbus.
Table 2. Power Supply
If a CPU with 3.3V is used on B5, this voltage is gained from the 5V using a linear
regulator.
2.1.2 SRAM and Real-Time Clock Battery
For uninterrupted power supply to the static RAM and real-time clock on the B5, an
external battery must be connected (minimum 3V). Thus, the user himself is
responsible for choosing a battery that represents the optimum solution for the
respective application in terms of environmental protection, availability etc.
Nominal battery voltage must be between 3V and 5V. The current necessary for data
retention heavily depends on the quality of the SRAMs and ambient temperature. It
is a typical 10µA for the RAMs. For instance, with a battery capacity of 1Ah this is
sufficient for 10 years, if self-discharge of the battery is neglected.
When the battery is being changed, data retention is guaranteed for approx. three
days if the battery voltage has not fallen below 2.6V or if the 5V supply has been
switched on for a short time before changing the battery.
Switching from mains to battery power is performed automatically with no loss of
data.
Battery voltage is applied to the +5VSTDBY line of the VMEbus connector.

2.2 Bus Structure
The B5 has two internal busses: a "local" 32-bit high-speed data bus and a "global"
16-bit bus.
Figure 5. Bus Structure
The local bus is not arbitrated, while the global bus is arbitrated according to the
round-robin principle. All units connected to the global bus are quasi-dual-ported,
i.e. they can be accessed both from the VMEbus and from the local bus. When the
CPU and the VMEbus want to access one of the units simultaneously, access is
granted alternatively. Read-modify-write accesses cannot be halted.
