Overview
1. Overview
1.1 Description of the EPPC-405-UC Module
Figure 1: Block circuit diagram
The EPPC-405-UC module is a stand-alone PowerPC in a stable, compact aluminium case.
Apart from a powerful CPU the PowerPC 405EP processor has got a SDRAM controller, a PCI-bus
interface, a controller for the serial interface and a MII-interface as Ethernet interface.
The memory equipment of the EPPC-405-UC comprises up to 64 Mbyte SDRAM as internal
memory, 1 Mbyte NOR-Flash and up to 128 Mbyte NAND-Flash. Furthermore, the board has got a
CompactFlash® interface. The CompactFlash cards can be accessed like an IDE-drive with
standard-system drivers. The CompactFlash slot is inside the module and can not be accessed
from outside.
All connectors of the module (except CompactFlash) are easily accessible via the font panel.
The three serial interfaces are equipped with RJ45 sockets.
The serial interfaces COM1 and COM2 are designed as RS-232 interfaces and the interface
COM3 as RS-485 interface. The signals of this interface are also accessible via a COMBICON
connector.
Both CAN interfaces are controlled by a SJA1000-CAN controller. The interfaces are designed
according to ISO11898, they are isolated by magnetic data couplers and can be used for
transmission rates of up to 1 Mbit/s.
The Ethernet interface is suitable for 10 Mbit/s and 100 Mbit/s nets. It is connected via an RJ45
socket.
Furthermore, the board is equipped with two USB host interfaces (socket type A).
The LEDs in the front panel show the status of the module.

NOTICE
Read the safety instructions at the beginning of this document carefully, before
you start with the hardware installation!
WARNING
Hazardous Voltage - Risk of electric shock.
All current circuits which are connected to the device have to be sufficiently protected
against hazardous voltage (SELV according to EN 60950-1) before you start with the
installation.
Mounting:
M1. For the mounting in the control enclosure position the lower clamp fastening of the EPPC-
405-UC module from below at the mounting rail. By pushing the module up and to behind
simultaneously it snaps in.
M2. Connect the plugs. Switch on the power supply and the participants to whose CAN network
or serial interface the EPPC-405-UC module is to be connected.
Demounting:
D1. Switch off the power supply and the other participants to whose network the EPPC-405-UC
module is connected (exception: not necessary for USB). Disconnect all plugs from the
EPPC-405-UC module.
D2. Unfix the module from the mounting rail by pushing the module up and to the front
simultaneously.

Installation / Maintenance
2.4 Change of the Battery
The EPPC-405-UC module has a RTC (Real Time Clock), which is energised by a battery. The
battery is fixed in a holder directly on the board.
Battery type: coin cell, 3V e.g. Panasonic CR1220 according to IEC 1220. It has an estimated
lifetime of approximately 4 years.
NOTICE
Electrostatic discharges may cause damage to electronic components.
→
→
To avoid this, please discharge the static electricity from your body by touching the
metal case of the system before you touch the EPPC-405-UC.
Furthermore, you should prevent your clothes from touching the EPPC-405-UC,
because your clothes might be electrostatically charged as well.
1. Remove the module as described under ‘Demounting' on page 11.
2. Unfasten the four upper, lateral screws, which fix the front panel. Remove the front panel.
3. Remove the old battery carefully out of the holder (see Figure 4) and replace it with the new
battery.
4. Replace the front panel again and fix it with the lateral screws.
5. Install the module as described under ‘Mounting’ on page 11.
2.5 Replace the CompactFlash Card
The CompactFlash slot is located directly on the PCB. It is not accessible if the case is closed.
The slot fits for card type I.
NOTICE
Electrostatic discharges may cause damage to electronic components.

1. Remove the module as descried under ‘Demounting’ on page 11.
2. Unfasten the four upper, lateral screws, which fix the front panel. Remove the front panel.
3. Unfasten the both lower screws on one side of the module. Remove the side panel.
4. Pull the board carefully to the open side along the track out of the case. Now the
CompactFlash card can be removed (see Figure 4) and replaced if necessary.
5. Insert the board along the lower guide track in the case.
6. Replace the side panel and fix it with the lower screws on the case.
7. Replace the front panel and fix it with the four lateral screws.

INFORMATION about Usage of CompactFlash® Cards!
A correct functionality of the CompactFlash interface can only be ensured by
usage of CompactFlash cards with guaranteed SSD-properties.
esd therefore recommends to use one of the listed SLC-cards:
- Western Digital SiliconDrive II (e.g. 4GB: SSDC04G-4600)
- Cactus CompactFlash 303 Series (e.g. 4GB: KC4GR-303)
- Swissbit C-320 (e.g. 4GB: SFCF4096H1BO2TO-C-D1-523-SMA)
Only with this CF-cards the correct function of the CF-card interface is ensured and
support for the devices is provided.
esd will evaluate more CF-cards and release them on success.
