Measurement Computing PPIO-AI08 - Manual (Page 5)

1 INTRODUCTION
The PPIO-AI08 is an eight-channel, 12-Bit A/D accessory for use with a parallel port.
The analog input channels are single-ended and can be in one of three ranges:
±10Vbipolar, ±5Vbipolar or 0 to 10V unipolar. The board also supports three digital
inputs and four digital outputs. All digital I/O are
TTL .
See the product specifications in Section 6 for more details.
2 SOFTWARE INSTALLATION
The board has a bank of switches for setting the gain. If you intend to use the default
range (±5V) then no configuration is necessary. If you intend to use one of the other
ranges, you should configure the board before connecting it to your PC. The simplest
way to configure your board is to use the InstaCal
™ program provided on the CD (or
floppy disk).
InstaCal will show you all available options, how to configure the various switches
and jumpers (as applicable) to match your application requirements. It will create a
configuration file that your application software (and the Universal Library) will refer
to so the software you use will automatically have access to the exact configuration of
the board.
Please refer to the Extended Software Installation Manual regarding the installation
and operation of InstaCal. The following hard copy information is provided as a
matter of completeness, and will allow you to set the hardware configuration of the
board if you do not have immediate access to InstaCal and/or your computer.
