Troubleshooting
This chapter gives you an introduction to diagnosing and resolving any
problems you may have in operating an application involving the IBM PC
I/O Scanner. After reading this chapter you should be able to:
check the installation of the scanner and correct it if necessary
check your program for likely errors and correct them
check and correct the connections of your 1771 Series I/O modules and
adapters
determine whether any remaining problems are most likely in your
software, in the scanner, or in the attached adapters and modules.
You should also have the manuals for your 1771 Series I/O products handy.
A troubleshooting chart for the 6008–SI module is presented on the pages
that follow.
Problem: Possible Solution:
Scanner does not
communicate with the IBM
U_D1 diagnostic program
does not run
Check dip switches 7-10 on the scanner board.
If IBM-XT, these switches should be open. If IBM-AT or T-50, these
switches should be closed.
(open = 1, closed = 0)
Check that dip switches 1-6 correspond to the address supplied in
the setup_6008() library routine or the /a option of the U_D1
program (open = 1, closed = 0)
Check memory map to insure a clear 6k + 1 memory window
Last resort. Set dip switches 1-6 to an open area of user RAM, or
remove some user RAM to create an open area. Install 6008-SI
there.
