BASIC OPERATION
Hardware Configuration
Connecting a Daughter Card.
Plug the daughter card into the DK101’s connectors. The daughter card should be
oriented as shown in
Figure 1
. Note that some daughter cards have a third connector for advanced features
(UTOPIA bus, POS-PHY bus, etc.). The DK101 is compatible with three-connector daughter cards, but does not
support the advanced features available on the third connector. These advanced features are supported on Dallas’
high-end demo kit platform, DK2000. When present, the third connector is located to the left of the other two
connectors (when oriented as shown in
Figure 1
). Note that daughter cards are not designed for hot insertion. Only
connect daughter cards to the DK101 motherboard with the power off.
Power Supply Connections.
Connect a 3.3V power supply across the red (V
CC
3.3V) and black (GND) banana
jacks. The green PWR LED should be lit to indicate power is applied to the board. The TIM STATUS LED should
be green to indicate that the DK101 recognizes the attached daughter card. If TIM STATUS is red, the DK101 is
not properly connected to the daughter card or does not recognize the daughter card.
If the daughter card has a device that requires a 5V supply, do one of the following:
1) To use the DK101’s on-board DC-DC converter (max current = 1A), set the three-position jumper marked
TIM 5V SUPPLY to BOOST CONVERTER.
2) To use an external 5V power supply, set the TIM 5V SUPPLY jumper to EXTERNAL and connect the
external power supply across the red EXTERNAL 5V and black GND jacks.
Connecting to a Computer.
Connect a standard DB-9 serial cable between the serial port on the DK101 and an
available serial port on the host computer. The host computer must be a Windows
-based PC. Be sure the cable is
a standard straight-through cable rather than a null-modem cable. Null-modem cables prevent proper operation.
Setting the DIP Switches.
For basic operation, use the following settings:
Switch number 1 OFF (flash program voltage not applied).
Switches 2 through 4 ON (8-bit daughter card; boot internal; run kit firmware).
Switches 5 through 8 do not affect operation of the kit firmware.
Installing the ChipView Software
To install the demo software on the host PC, run SETUP.EXE on the demo kit CD-ROM (or from the .ZIP file
downloaded from the our website,
www.maxim-ic.com/telecom
). Follow the instructions given by the SETUP
program. By default, SETUP installs the application software in “C:\Program Files\ChipView” and creates a shortcut
in the ChipView program group.
Running the ChipView Software
Run the ChipView application. If the default installation options were used, click the Start button on the Windows
toolbar and select Programs
ChipView
ChipView. The main menu window provides three options: Register
View, Demo, and Terminal Mode. Register View mode and Demo mode are discussed in the following paragraphs.
Terminal mode is discussed in the
Advanced Features
section.
Register View Mode
Register View provides an intuitive user interface for reading, writing, and viewing the IC registers on the daughter
card. Register bytes and bits are displayed by name in an on-screen array. Values can be read or written with a
click of the mouse.
Figure 2
shows an example of the Register View window.
To go to Register View from the ChipView main menu window, follow these steps:
1) Push the Register View button in the main menu window. A popup window for COM port selection
appears next. Select the appropriate port from the menu and click OK. Next, the Definition File
Assignment window appears. This window has subwindows to select definition files for up to four
separate daughter cards. Because the DK101 platform only interfaces with one daughter card at a
time, only one subwindow is active.
