5.2 MVB Configuration
The MVB module configuration is done through the Gateway CPU, and the MVB reads
it through its shared memory at the start-up of the system.The configuration is for the
MVB module read-only, and only managed by the CPU software. If any changes are
made through the debug terminal, the original configuration is retained when the
module is reset.
The MVB module can also be configured to act as a slave in the Multifunction Vehicle
Bus to another MVB module acting as the Bus Administrator, and in test circumstances
to simulate the MVB subsystems’ logical ports. This is however only done by changing
the configuration through the Gateway CPU.
5.3 Firmware loading
If you need to download a new firmware version onto your module, follow the
instructions below.
1 Remove all other modules from the rack except for the MVB and the PSV Power
Supply Module.
Never install or remove modules to / from the rack with active power.
Always turn off the rack power first.
2 Connect a USB cable between your PC’s USB port and the EKE-Trainnet
®
USB
floader unit (UFI 1528). Then connect the EKE-Trainnet
®
FAC 1027 cable between
the USB floader unit and MVB module (connector X4).
3 Start the USB Floader program on your PC.
4 Locate the “MVB.ufo” file and click “OK”. Loading will start, and loading progress
window appear.
5 The program informs when the download has been executed successfully. If the
module does not reboot automatically after the download, reboot it manually.
5.4 Getting started with troubleshooting
Before starting to use the diagnostics software for troubleshooting an MVB module,
make the following preparations:
 Make sure your PC includes a terminal software such as HyperTerminal. This
software is not provided with EKE-Trainnet
®
modules.
 Connect the rack to your PC using the cable and adapter you have received with
the TCN delivery containing EKE-Trainnet
®
modules.
 Connect the module to the rack directly or through an extension board.
