2.2.6 Installation of Data Control Board (DCB)
The ACR-2000 Reader is controlled by a proprietary Lumisys Data Control Board in an IBM type PC.
The DCB is 8 bit ISA. The DCB uses three resources, IRQ, Mem Seg Addr, and Base I/O Addr.
Note1: The ACR-2000 product contains a pre-configured PC workstation. It is not necessary to install the
Data Control Board unless a different PC is used.
Note2: If a replacement DCB is to be installed in a PC supplied by Lumisys, the PC will likely be set to
use certain resources for the DCB. These likely resources are IRQ 7, Mem Seg D800, and Base I/O 100.
It is recommended to set the DCB to these resources before installation. Please consult Appendix A for
the resource chart.
With power off, remove cover from the target PC or compatible(See Note below). Taking appropriate
anti-static precautions, remove the Data Control Board from the accessory box and install it in an 8 or 16
bit ISA slot. Secure the DCB in the slot and replace the covers.
The Data Control Board is factory configured to use IRQ 5 , I/O Addresses 100-11F and has a 32
KByte window at hex address D0000-D7FFF. If these addresses conflict with your system configuration
they may be changed. Please see APPENDIX A for instructions on how to change the IRQ level, the I/O
address, or the 32 Kbyte window address.
