Custom GPS/GSM and

Fieldbus Interface

This 3U CompactPCI

board for infotainment

systems features a combination of well-

estab lished standard industry interfaces in

wireless and ﬁ eldbus communication, accom-

panied by legacy two-wire RS485 interfaces

(realized in FPGA) and some optically isolated

binary I/Os for general purpose functions.

All connections are available at the front panel

of the board. In parallel 16 binary I/Os and

one RS485 can be accessed via rear I/O. The

board is fully compliant with railway standard

EN 50155.

1 GPS interface

1 GSM interface

1 IBIS master interface

1 CAN bus interface

1 Tacho interface

2 RS485

5 binary inputs

8 binary outputs

3U CompactPCI

Ethernet

Switch F301

The F301 is a Fast Ethernet Switch module

with an integrated Fast Ethernet controller

and a maximum of 8 channels at the front

panel (8 RJ45 or 6 D-Sub connectors). The

Ethernet switch is an unmanaged device,

meaning that it is not recognized by other

CompactPCI

devices thereby removing the

need for additional software.

An on-board Ethernet controller is used to

realize the interface to the CompactPCI

bus.

The F301 also works without the Ethernet

controller being assembled. In this case the

CompactPCI

bus only delivers the power

supply. As an option the J2 connector can be

assembled and used to manage the rear I/O

Ethernet signals from the ninth Ethernet port.

The F301 is speciﬁ cally designed for rugged

mobile communication systems and is fully

compliant with EN 50155.

Up to 8 Fast Ethernet ports (front)

1 Fast Ethernet controller (rear J1)

Option: 1 Fast Ethernet port (rear J2)

Digital Input M-Modules™

M31 and M32

A current limit for each input guarantees the

wide input voltage range of 0 to 155V on the

M-Module mezzanine cards M31 and M32.

They have latching and comparator capabili-

ties and a digital circuit to debounce signals of

mechanical switches. The precision deboun-

cing time of 300ns to 100ms is software-

conﬁ gurable and programmed in a PLD.

Each input signal edge generates a maskable

interrupt for the respective channel. The MTBF

is deﬁ ned at 50°C and reaches 300,000 hours

per M-Module.

M31 and M32 are designed in accordance

with EN 50155.
