7.2 Power Supply
With the adapter cables in use, the requirements for the signals to and from the 9522B are as given in
section
3.3. Note that it is important to ensure that the power supply voltage measured at the 9522B
multi-way connector does not fall below 4.0v. In order to allow for the voltage drop due to the resistance
of the adapter cable and connectors, it is recommended that the voltage at the 25-way D-type connector
should be 4.2v minimum. If it is possible to change the supply voltage in the application, it is
recommended that 5v, 12v or 24v is used, as the effect of voltage drop will be reduced and the 9522B
operates more efficiently.
