Hardware Description

ACL-7120 is a digital I/O and counter card for IBM PC/AT and compatibles. It has a little bit of everything on-board:

• 32 Digital Inputs
• 32 Digital Outputs
• Three or Six 16-Bit Counter/Timer Channels
• A Breadboard Area for Circuit Design

All these features make the ACL-7120 a powerful "Swiss Army Knife" of Digital I/O Cards.

• Digital I/O
  Its digital inputs and outputs are TTL-compatible and use 74LS244 driver/buffer chips to provide high output drive. The circuits also demand less current than regular TTL circuits. It is very suitable for most industrial applications.

• Counter/Timer
  Dual on-board programmable counter/timer provides 3 or 6 channels for fre-quency measurement, event counting and pulse generation. The clock frequency is jumper selectable for 2MHz, 1MHz, 500KHz and 250KHz. The maximum data throughput can be up to 500K bps.

• Breadboard Area
  A breadboard area (651 plated-through-holes) facilitates the construction of customized circuits such as filter, attenuators, etc.

• Power Consumption
  +5V @ 500mA Typical

Two software development kits are supported for the ACL-7120, they are:

• Windows 3.x Driver (ACLS-DLL1) The ACLS-DLL1 is a high performance Windows driver for Digital I/O functions. It supplies a DLL that can be accessed from C, C++ and Visual Basic under Windows 3.x environment.

• Program Library & Examples
  An extensive library of functions are available that support Microsoft C and Borland C/C++. Example programs are included to demonstrate how to write C programs for the ACL-7120.
