Concerns When Using the PCMCIA-FBUS Interface with a Cardbus Controller.Hardware: Industrial Communications>>Fieldbus>>PCMCIA-FBUS
Problem: The PCMCIA-FBUS card will not function correctly in some laptop computers with Cardbus controllers. Solution: The National Instruments PCMCIA-FBUS interface card requires 5 Volts DC at 500 mA in order to operate correctly. However some Cardbus controllers operate in a low power consumption mode that supplies only 3.3 Volts DC to the PCMCIA socket. If this is the case, the PCMCIA-FBUS interface will not be able to function properly. Before using the PCMCIA-FBUS interface in any laptop, it is highly recommended that the laptop manufacturer be contacted and the capability of the PCMCIA socket to source 5VDC at 500 mA be verified. The following link explains the Cardbus standard in more detail as well as its compatibility with PCMCIA.
