4. Basic Operation
Note: In the following sections, software-related items are identified by bolding. Text in bold refers to items directly
from the EV kit software. Text in bold and underlined
refers to items from the Windows operating system.
4.1 Powering Up the Demo Kit
Connect PCB power jack to the wall adapter.
Connect RS232 serial cable, or USB cable between the host PC and demo kit.
Verify that the jumpers are configured as described in
Table 5-1.
4.1.1 General
Upon power-up the power LEDs (DS30, DS31, DS32 green) will be lit. Note that with DS33M3301A0 board
revision, the LED DS31 will be red when power conditions are correct.
PHY LINK LED should be lit if an Ethernet cable is connected.
Following are several basic system initializations.
4.2 Basic DS33M33 Initialization
This section covers two basic methods for configuring the DS33M33.
1. Device Driver-Based Configuration: (Note: The DS33M3302A0 board revision does not come loaded with
device drivers). If the pins J20.1+J20.2 are Jumpered the device driver will auto configure the DS33M33
upon power-up. This enables traffic to pass from the Ethernet port to the serial port. Consult the device
driver documentation for further details. To load the GUI interface for the device drivers, go to the ChipView
register mode Tools menu and select ToolsPluginsDS33M30/M33 Device Driver Demo.
2. Register-Based Configuration: EoS VC3 with two ports assigned to VCG1.
a. Remove jumper J20.1+J20.2 to disable device drivers, and reset the board.
b. Launch ChipView.exe and select Register View.
c. When prompted for a definition file, pick the file named _DS33M33_GlobalMicroport.def. Several
additional definition files will load.
d. Go to the File menu and select FileMemory Config FileLoad .MFG file. When prompted,
select the file named m33_eos_vcg0_port2_port3_mii.mfg.
4.2.1 Additional Configuration for DS33M33
Using either a patch or crossover cable, connect the Ethernet connector to an ordinary PC or network test
equipment. This should cause the link LED to turn on.
Place a loopback connector at the SONET network side; the optical LOS LEDs should go out.
At this point any packets sent to the DS33M33 are echoed back. Incoming packets (i.e., ping) should
cause the Activity LED to blink.
Note that ChipView.exe display settings can be changed using the OptionsSettings menu.
4.3 Monitor and Capture Ethernet Traffic
Although ping is mentioned, it is not the recommended frame source for testing. The ping command goes
through the computer’s TCPIP stack, and sometimes is not sent out the PC’s network connector (i.e., if the
PC’s ARP cache is out of date). Additionally, ping requires two PCs, as a Windows PC with only one
adapter cannot ping itself (i.e., a local ping gets sent to local host instead of out the connector). With that
said, ping is still a valuable test once the prototyping stage is complete.
Generation and capture of arbitrary (raw) packets can be accomplished using CommView. A time-limited
demo is available at www.tamos.com/products/commview.
Wireshark (formerly Ethereal) is a free packet capture utility. Download is available at www.wireshark.org.
Adding additional Ethernet ports to a PC is rather simple when a USB-to-Ethernet adapter is used. This
allows for end-to-end testing using a single PC. When using two adapters, the PC has a different IP
address for each adapter. Test equipment allows selection of either adapter. Operating system-based
