Getting Started with the DS1840K . . .

Using the DS1840K Software
Before starting the DS1840K Software, make sure that a device is properly installed and that power is
applied to the banana jacks. Also, be certain that the serial port dongle (DS9123) and cable are connected.
To start the application, go the Start menu and select:
Start\Programs\Dallas Semiconductor\DS1840K Kit\DS1840K
Or, if you chose not to install, look for the executable named
DS1840K.EXE
and double click it.
When the following dialog
box appears (Figure 10),
simply choose the device that
you would like to evaluate and
click “OK”.
Figure 10. DS1840K device selection dialog box.
The DS1840K Kit Software finally appears. The first item to look for is the status in the lower left corner.
If the DS9123 (connected to the serial port) is found, then the text should read “DS9123 ready!”. LED2 on
the board should also be illuminated. LED2, if lit, indicates that the serial port is now open. If the status
box displays “DS9123 not found!”, then click on the radio button next to “COM2”. Then click “Apply”. If
the status box displays “DS9123 ready!”, you are ready to continue. Otherwise, if you are still
experiencing difficulties, refer to the “Troubleshooting” section of this document.
The kit software is based on Windows property sheets. The first “page” that appears is the General page
(see Figure 11). This page is
common to all of the DS184X
devices. In addition to the
status box already discussed,
the General page also contains
the “Serial Port Settings”
options. If you ever need to
change the COM port, do not
forget to click on “Apply” so
the changes will take affect.
In the “Serial Port Settings”
box you will also find a Test
Port button. This button is
only necessary for diagnosing
serial port and DS9123
problems. The General page
also contains the selection for
the 2-Wire Slave Address.
This address needs to match
the DIP switches for A0, A1,
and A2. The default of the
Figure 11. DS1840K General page.
Slave Address is 000, which matches the default DIP switch settings. The last option found on the General
page is the Enable LED1 checkbox. While LED2 indicates that the serial port is open, LED1, if checked,
