... ADT7461. This connector is also used to con- nect an external remote thermal diode between the D+ and D– terminals of the ADT7461. Centronics Interface Cable J2 The evaluation board and the personal computer may be con- nected via the printer parallel port using the Centronics cable provided. Power Connector J3 and Switch SW1 Power can be supplied to the board either via the Centronics cable or via the power connector J3 ...

... For more information on series resistance cancellation, see the ADT7461 datasheet. If the user has both variable resistors connected in to the evalua- tion circuit, then the total resistance being cancelled by the ADT7461 is the sum of both resistances. If only one of the variable resistors is connected in, then the total resistance being cancelled is the value of that resistance only ...

... The following is the main program tab that appears when the software is started. There are three main sections to the evaluation software, which can be accessed easily from the tabs at the top of the evaluation window. The Read/Write section gives the user easy access to the ADT7461 registers. The Control Center window lets the user graph the temperature outputs of the ADT7461, check for interrupts, and set up log files ...
