APPENDIX A: LUMISCAN ACR-2000 Reader JUMPER AND SWITCH SETTINGS

______________________________________________________________________________

Identifying your Data Control Board (DCB)

There are three versions of the DCB in existence. The newer DCB3 has slightly different switch

settings than the DCB1 or DCB2. Here’s how to identify them:

Address Memory Base I/O Memory

Ver Size IRQ DIP Switch Address Address Size

DCB1 Big (13” long) JP1 S1 (6 bits) S1-1 thru S1-5 S1-6 N / A

DCB2 Med (9” long) JP2 S1 (6 bits) S1-1 thru S1-5 S1-6 N / A

DCB3 Small (6” long) JP2 S1 (8 bits) S1-1 thru S1-5 S1-6 thru S1-7 S1-8

Changing IRQ Level

The LUMISCAN 50 / 75 / 85 is factory configured to use IRQ level 5. The IRQ level may be

changed by setting a jumper on the Data Control Board (JP1 or JP2, see table above). To change the

setting, remove the jumper from its current position and move it to the desired level.

JPx (see above table)

IRQ

If the IRQ is changed from level 5 you MUST inform the driver when it is loaded. This is

accomplished by using a switch. The switch is a forward slash (/) such as used with MS-DOS

commands. The format is /Ix, where x is the IRQ level. For example, to install the driver using IRQ

6 from the MS-DOS prompt you would enter "LSDTVxxx /I6".
