P50-104: bridge/front-end


Who we are



Bridge /
for PC104 bus


LEOMATIC P50-104 card allows to connect any SYSTEM5 family module to a PC104 system. Suitable for any PC104 system, it has 2 CANBus ports on which may be connected any module of SYSTEM5 family.

You can fit the P50-104 on the PC104 bus, while Leomatic SYSTEM5 modules may be placed along the machine (according to a long-distance distributed architecture).

A DSP microprocessor at 400 MHz grants very fast communications with Leomatic modules, relieving PC104 CPU from polling time.

Leomatic supplies P50-104 cards with a free-of-charge software library, which contains procedures/methods allowing to handle all of hardware resources of SYSTEM5 modules and to realize easily a control software for the specific application on the PC104 CPU.

The on-board firmware, stored on Flash memory, may be changed  (downloaded) through a dedicated software tool.

It is possible to ask Leomatic for a customized Firmware version.

    The on-board firmware can work in 2 different ways:

    Forwarding: P50-104 acts like a simple bridge between the PC104 CPU and all the Leomatic SYSTEM5 modules connected via a CANBus network. Control software of PC104 CPU can access any connected module through this bridge.

    Front-End: P50-104 acts like a intelligent front-end, polling  all the Leomatic SYSTEM5 modules connected via CANBus network and presenting their refreshed images to the PC104 CPU.
Control software of PC104 CPU can read/write the resources of all connected modules accessing only the P50-104 card; this relieves very much the work of the PC104 CPU.

    The third CANBus port is dedicated to service functions,  available through a software tool (supplied free-of-charge), such as:
- download of the on-board firmware of P50-104 and/or of any connected module;
- test / diagnostic of P50-104 and/or of any connected module.

    In case of malfunctions, you may activate a special boot firmware, stored on a protected page of flash memory.
It grants a recovery startup: some functions are reduced but the Leomatic protocol on
third CANBus port is fully operative, so you can run the software tool in order to download the on-board firmware or to test the card itself.
