6. g Outputs There are two independent analog outputs Both have 12 bit precision and both are software configurable to any of the following ranges e OV to 5V e OV to 10V 5V to 5V e 10V to 10V e 2 5V to 2 5V e 2 5V to 7 5V Motor Controllers Two independent motor controllers are provided These controllers are capable of directly driving DC brush motors Due to the large amount of power required by most motors the motor controller interface has a separate power supply connection for each motor This also allows each motor to operate at a different supply voltage To help prevent damage to the controllers each has overcurrent and thermal warning shutdown protection If the current exceeds approximately 10A the controller will shutdown Similarly if the controller reaches 145 C a thermal flag will be set that can be read through the USB This allows the controlling software to Rev 4 4 1 6 10 EQ Dajac Inc Expert I O 1000 Hardware User Manual take action to reduce the temperature such as slowing the motor However if the temperature continues to rise the controller will shutdown at 170 C For both current and temperature shutdown the controller will automatically restart when the error condition is cleared Analog Inputs There are six 8 bit analog inputs A separate ground connection is provided with each input to help reduce noise issues Digital Outputs Sixteen digital out
7. puts are provided as two 8 bit ports P2 and P3 Each of these outputs are push pull giving them the ability to source and sink current Additionally the voltage level for logic high output is software configurable to the following levels 3 3V This setting is available for both ports P2 and P3 e B The logic high voltage is B volts This setting is only available for P2 See Section B B1 e B1 The logic high voltage is B1 volts This setting is only available for P3 See Section B B1 Digital Inputs Sixteen digital inputs are provided as two 8 bit ports PO and P1 Each input operates over a wide range and each has a software configurable 100KQ pull up or pull down The pull voltage can be configured as follows e None The pull is disabled This setting is available to both ports PO and P1 e 3 3V The input is pulled to 3 3V This setting is available for both ports PO and P1 e Ground The input is pulled to ground This setting is available for both ports PO and P1 B The input is pulled to B volts This setting is only available for PO See Section B1 B e B1 The input is pulled to B1 volts This setting is only available for P1 See Section B1 B The digital inputs have a state change notification feature When an input changes state a flag is set This flag can be read through the USB EEPROM In addition to the I O described above the Expert I O 1000 also includes 2 Kilobytes of user accessible
