Table 1: Connectors




2.1 DHCOM (U27)

Any DHCOM standard module can be plugged into the SODIMM-200 connector.

2.1.1 DHCOM power supply voltage

It is possible to choose the supply voltage for the DHCOM standard module:

If the resistors R106 and R107 are placed, the module is supplied by 3,3 volt (default)

If the circuit under resistor R106 is ripped and resistors R104 and R105 are placed, the module is sup-

plied by 5,0V.

Beware: Do not place R106, R107 AND R104, R105 at the same time. This will destroy the development board.




2.1.2 DHCOM current consumption measurement (X43)

The PDK2 offers the possibility to measure the power consumption of the DCHOM standard module.

If you want to measure the power consumption follow these instructions:

Unplace resistor R311

Rip the short circuit under R311

Place resistor R311 again

Measure the supply voltage of the DHCOM standard module

Measure the voltage on header X43

P_dhcom = (voltage on X43 / 2) * supply voltage of the DHCOM

Example:

Supply voltage of the DHCOM = 3,31V

Voltage on X43 = 0,94

P_dhcom = (0,94/2)*3,31 = 1,56Watt

Table 4: SD Card signals on male header

The SD Card interface is supplied by a separate power supply. Per default the voltage is 3.3 V.

The PDK2 offers a level shifter for the SD Card signals. Because of this you don’t have to consider the signal

voltage of the SD Card interface of the DHCOM Standard Module

2.5 CAN Interface (X4)

The PDK2 offers the connector X4 for CAN communication. Onboard is a galvanically isolated CAN transceiver

that meets the specifications of the ISO 11898 standard.

The DHCOM Premium Developer Kit supports three UARTs, a Full Function UART1, a Bluetooth UART2 and a

Standard UART3. The Bluetooth and Standard UART are only with TTL voltage level available whereas the Full

Function UART is with TTL voltage level and RS232 voltage level available.

To connect UART2 and the UART3 with your host PC you can connect a TTL to USB cable (e.g. FTDI TTL-232R-

3V3)

2.6.1 UART1

2.7 PLD

The DHCOM Premium Developer Kit has a PLD (programmable logic device). The PLD is connected to a 24MHz

crystal. The 16bit address bus and 16bit data bus from the DHCOM Module are connected to the PLD. Also the

chipselects CS_A, CS_B, CS_C, CS_D and CS_E and the control signals WE (write enable) and OE (output ena-

ble) are routed to the programmable logic device. Additionally the GPIOs I, E, F, H and D are connected to the

PLD. A free programmable status LED LD1 is also available.

In order to program the PLD you have to establish a JTAG connection to the PLD via the connector X10.

To write your own VHDL-code you can use the ispLever Classic Software from Lattice (www.latticesemi.com).

You also need a programmer (e.g. HW-USBN-2A from Lattice) to deploy the VHDL-Code on your PLD.




With the PLD IO connector X11 it is possible to tap the in- and outputs from the CPLD and connect new periph-

eral devices (e.g. SRAM).

A Demo VHDL-code can be found under http://xlon.de/wiki/index.php?title=Software_428-500. Per default the

CPLD is programmed to route the address- and databus directly to the PLD IO connector X11.

in OTG mode. If the header is open the USB OTG port is available in client mode only.

2.8.4 USB Host on Display-connector

One USB host is routed to the display interface. See more information in the chapter “Display-connector”.

2.9 Display-connector

2.9.1 Information about the display connector

The display interface uses a unified display interface pin out. To connect your display with the DHCOM Premium

Developer Kit2 you should take a look on the DH website or ask for our support.

DH electronics GmbH uses a Display Interface Board (DIB) to connect a display to the DHCOM Premium Devel-

oper Kit.

The following interfaces are on the Display-connector available:

+24V supply voltage (max. 800mA)

+5V supply voltage (max. 500mA)

Table 15: Dual Ethernet

Depending on the used DHCOM Standard Module there is the possibility to set the upper RJ45 socket (= DHCOM

Ethernet port1) up to a GBit connection.

If the resistors R328, R329, R330 and R331 are placed you can use (depending on the used DHCOM Standard

Module) both Ethernet ports with 100MBit.

If the resistors R328, R329, R330 and R331 are NOT placed and the resistors R332, R333, R334 and R335 are

placed instead you can use (depending on the used DHCOM Standard Module) the upper Ethernet port with

1GBit. The lower port is not connected anymore and can’t be used.

There is the possibility to do a quick change between 100MBit and 1GBit. If you unplace all resistors R328, R329,

R330, R331 and R332, R333, R334, R335 you can set the bandwidth by placing jumper bridges on X46, X47,

X48 and X49.

2.10.2 RJ45 GBit Ethernet Interface

The PDK2 offers the possibility to set up a GBit connection. Whether the GBit interface is supported and can be

used or not depends on the DHCOM core modules used in each case. Just modules with the DHCOM-X interface

support the GBit Ethernet interface. A detailed description can be found in the respective DHCOM core module

User Manual.

Table 17: PCIe

The PCIe clock signal of the i.MX6 module has a too big jitter for PCIe 2.0. If you want to use PCIe 2.0 or higher

with the DHCOM i.MX6-module, you have to use another PCIe clock signal.

Because of this there is an additional clock generator placed on the PDK2. You will get further information from

DH electronics GmbH.

2.14 MIPI CSI-2

The PDK2 offers the possibility to use a MIPI CSI-2 interface with two data channels and one clock channel.

Whether the MIPI interface is supported and can be used or not depends on the DHCOM core modules used in

each case. Just modules with the DHCOM-X interface support the MIPI interface. A detailed description can be

found in the respective DHCOM core module User Manual.




The pinout of the MIPI CSI-2 connector fits to the e-CAM51IMX6 camera from e-con-Systems. So there is fast

way to connect a camera the baseboard and evaluate the interface.

IMPORTANT: The ffc connector is able to contact on top and bottom. Please consider the polarity!

If a DHCOM module has an own audio codec or you want to use your own audio codec on a separate pcb it is

possible to tap the signals before the audio codec on the PDK2. Therefore it is necessary remove the resistors

R109, R200, R203 and R204.

2.16 Jumper Bridge

With the DHCOM Premium Developer Kit2 you have the possibility to configure which signals from the SODIMM-

200 connector will be transmitted to the peripheral devices and which won’t.

E.g.: If you don’t want to connect the UART3 data lines with the UART3 connectors you have to open the Jumpers

for the UART3 Interface and no signals will be routed from the SODIMM-200 connector to the UART3 connector.

For standard use all signals are jumpered. With this configuration you can use all available interfaces. It is pos-

sible to design a printed board and connect this to the Jumper-Field in order to get access to the different func-

tions (e.g. RS485-interface, I²C-ADC …).

2.17 Camera connector

It is possible to connect a 10 bit CMOS image sensor with connector X20 to the DHCOM Premium Developer

Kit2.

If the DHCOM GPIOs GPIO_A to GPIO_I are not enough it is possible to use the Camera Interface Pins as GPIOs.

The numbers of available GPIOs increases from 9 GPIOs to 23 at most. The number of additional available GPIOs

is depending on if the Camera Interface is available on the DHCOM module and how many data lines are availa-

ble.

2.19 GPIOs

The following diagram shows the available GPIOs and their different functionality.

Figure 6: GPIO routing

a) First in order to ensure interoperability the GPIO signals are routed to the jumper bridges.

b) From the jumper bridges the GPIO signals are connected to the levelshifter.

c) From the levelshifter the GPIOs A, B, C and D are routed to the Buttons and to the display. Additionally

GPIO D is connected to the PLD and GPIO G is connected to the display.

d) The GPIOs E, F, H and I are connected to the PLD and to the display connector too. Complementary the

GPIOs E, F, H and I are connected to a buffer too. From these buffers the GPIOs can be used as outputs

only.

e) The GPIOs E, F, H and I are routed after the buffer to the LEDs. GPIO E, F before the buffer. GPIO I at the

display connector can be used just as output!




2.20 Reset-Button (RESET1)

In order to reset the system you have to press the reset button RESET1.

2.21 Power supply

The voltage supply for the PDK2 is 24V ±10%. Board regulators generate three supply voltages:

1,5V/700mA

3,3V/5A

5V/5A

The power consumed by the PDK2 largely depends on the core module used and the peripherals connected to

the USB ports.

The PDK2 supply voltage is connected either to the 2-way connector X23 or to the connector X24. The pin as-

signments of both connectors are shown in the following figures:

Figure 3: Pin assignments of connectors X23 and X24

The following Phoenix plugs may be used as connectors for the voltage supply connector X23:

Art. No.: 1847055 (MC 1,5/ 2-STF-3,5)

Art. No.: 1840366 (MC 1,5/ 2-ST-3,5)

Art. No.: 1863152 (MCVR 1,5/ 2-ST-3,5)

2.22 Goldcap

A goldcap for backing up the time and date information is connected to the battery pin of the DHOCM.

Depending on the used DHCOM the goldcap is able to back up the time and date information for 2 weeks after

full charging the goldcap.

2.23 Cooling concept

DHCOM core modules with high end CPUs like i.MX6 must be preserved from thermal damage if they are run-

ning at full load. The DHCOM Standard cooling concept uses the following techniques to solve the heat problem:

Heat dissipation from the cpu core to the inner layers of the baseboard

Heat dissipation from the cpu core to a heat sink on the backside of the baseboard

Figure 9: Cooling concept – dissipation on the rear of the carrier board

The PDK2 has a non-covered copper area on the top and the bottom side to contact the cpu core with a low

thermal resistance to the PDK2.

A detailed description which DHCOM module requires a special cooling can be found in the respective DHCOM

core module User Manual.
