2 Overview
2.1 Features
The CB2050 is a computer motherboard for industrial applications. It complies with the PISA-Slot form
factor and ships with either Intel® Celeron® M or Intel® Pentium® M CPUs. Two SO-DIMM200 slots allow
a maximum of 2 GByte DDR-333 RAM. The CB2050 offers a high degree of flexibility in terms of
connecting external devices to the board. In addition to the PCI bus being available through the PISA
connector there is also a MiniPCI connector. Furthermore we have two IDE channels, four serial ports, two
LAN connectors, several analog and digital sound in- and outputs, six USB ports, CRT and LCD
connectors.

3 Connectors
This section describes all the connectors found on the CB2050.
CAUTION
For most interfaces, the cables must meet certain requirements. For instance, USB 2.0 requires twisted and
shielded cables to reliably maintain full speed data rates. Restrictions on maximum cable length are also in
place for many high speed interfaces and for power supply. Please refer to the respective specifications and
use suitable cables at all times.

Chapter: Connectors Power Supply
page 16 Beckhoff New Automation Technology CB2050
3.1 Power Supply
The power supply of the hardware module is realized via a 2x8-pin connector (Molex PS 43045-16xx,
mating connector: Molex PS 43025-16xx). The pins for 12 volt have the sole purpose of supplying one or
both fans with the necessary current. Thus, when no fan is installed, these pins have no function. COM3
RXD and TXD can also be used for connecting a second power supply unit, e. g. for UPS. As an ordering
option SMBus signals SCL/SDA can be provided (replacing COM3 TXD/RXD).

3.2 CMOS Battery
The board ships with a CR2032 battery holder (Renata VBH2032-1) and 3V battery. Alternatively, an
external battery can be connected via a 2pin connector (JST B2B-EH-A, mating connector: EHR-2).

3.3 System
Some typical signals for system control are provided through a 2x9 pin connector (JST B18B-PHDSS,
mating connector: PHDR-18VS). This connector combines signals for power button, reset, keyboard,
speaker, and several LEDs such as harddisk LED, touch screen LED, suspend LED, and three additional
LEDs which are driven by GPIOs. Of these three GPIO-LEDs, LED1 and LED2 are already provided with a
series resistor. As can be seen from the pinout table below, corresponding signals are often placed vis-à-vis
or at least near to each other.

PISA Slot Chapter: Connectors
Beckhoff New Automation Technology CB2050 page 19
3.4 PISA Slot
The CB2050 module requires a backplane board in which it is inserted using the PISA slot. This slot
combines PCI and ISA signals in one single connector which is useful in situations where limited space is
an issue. The CB2050 currently supports only PCI.
NOTE
Please note the unusual pin numbering scheme of the PISA slot. There is an "up row" (for ISA signals) and
a "low row" (for PCI signals). The former is divided into segments A through D while the latter is divided into
segments E through H (cf. the illustration above).
