Functional Description
CPB904
4.3.18 Discrete
Input/Output
17 programmable input/output channels use FDD/LPT port lines.
4.3.19
Power Supply Connector
The power is supplied to CPB904 via ETX connectors in normal operation mode or via Aux Power
connector (J6) located on the top side of the module in module's test mode only. To enable
module's ability to be powered via J6 connector it is necessary to close pins on J5 pinpad. This
co5VSB voltage to module's +5V lines. Please, observe polarity while connecting wires to
J6 connector.
The main power voltage of the processor module is +5V. +3.3V voltage is generated onboard, it
may be used to power devices on baseboard with consumption current of up to 0.2 A.
4.3.20 ETX
Connectors
CPB904 is equipped with four standard ETX low-profile 100-contact Hirose connectors to supply
module's interfaces to KIB1282 baseboard. The following four tables provide information on ETX
connectors contacts designation.
