Analog Inputs

1.3 Analog Inputs

Analog input is supplied through the ten–way screw terminal block, J4. The nine inputs are connected to the MSC1211 through a 100resistor. There is also a terminal block for AGND. The inputs have the 100resistors to provide minimal protection against overvoltage.

1.4 Prototyping Area

A prototyping area is provided on the MSC1211EVM. This may be used to in- corporate additional circuitry, such as special reference or conditioning cir- cuits, into the system. All of the signals on the MSC1211 are brought to con- nector pads. Additionally, there are digital and analog power and ground holes in the prototyping area.

1.5 Power Requirements

The MSC1211EVM must be supplied with 5.5V to 15V for proper operation. Power can be supplied through barrel jack J6 (tip positive), square pin connec- tors JMP5 (pins 2 and 3) and JMP6 (pins 2 and 3), or with a 9V battery con- nected to battery snap B1.

A 9V “wall–wart” power supply is included with the MSC1211EVM.

1.6 Host Computer Requirements

The Raisonance software development environment is designed to run on a PC running any Windows platform (Windows 95, 98, NT, 2000, etc).

Minimum Requirements:

-IBM-compatible 486 PC or higher

-Windows95/98/2000 or NT4.0

-64MB RAM minimum

-20MB available hard disk space

-CD-ROM drive

-Available serial port
