Chapter 10
User Diagnostic Program
10-2
If your switch settings on the scanner board are as set at the factory, you
can start the diagnostic program by simply entering its name at the DOS
prompt:
u_d1
Userset switches
If you have changed the settings of switches, you need to tell the program
where in memory it will find the scanner board. To do that, use the
/a
option with the memory address (in hex), like this:
u_d1 /aD800
A chart in chapter 3, “Installation,” shows how switch settings on the
scanner board correspond to memory addresses in the host computer.
Other options
The u_d1 program normally assumes that your I/O devices are set at 57.6
Kbaud, that you want the line termination resistor connected, IRQ3 is
selected, and that a 1s timeout for management requests is adequate. You
can change these assumptions either at program startup by specifying
options on the command line, or later while the the program is running. A
space or tab must precede every option, including the
/a option. We give
the options in lower case here, but upper case works too.
The following options are defined:
/b specifies baud rate. Follow the b immediately (no spaces or tabs) with a 1 for
57.6 baud or a 2 for 115.2 baud. /b1 is the default.
/n specifies the interrupt request line. Follow the n immediately with 3 for IRQ3, 5
for IRQ5, 10 for IRQ10 or 12 for IRQ12. /n3 is the default.
/r specifies the line termination resistor. Follow the r immediately with a 1 for
connected or a 0 for not connected. /r1 is the default.
/t sets the initial timeout for management requests. Follow the t immediately with a
decimal number of 55 milliseconds. The default is /t18 units, about a second.
Example: “u_d1 /b2” starts the program with initial operation at 115.2
Kbaud.
