Digi RCM4000 user manual Click OK or Close to exit the various dialog boxes

Follow these instructions to set up your PC or notebook. Check with your administra- tor if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows.

TIP: If you are using a PC that is already on a network, you will disconnect the PC from that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network.

1.Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon.

2.Select the network interface card used for the Ethernet interface you intend to use (e.g., TCP/IP Xircom Credit Card Network Adapter) and click on the “Proper- ties” button. Depending on which version of Windows your PC is running, you may have to select the “Local Area Connection” first, and then click on the “Properties” button to bring up the Ethernet interface dialog. Then “Configure” your interface card for a “10Base-THalf-Duplex” or an “Auto-Negotiation” connection on the “Advanced” tab.

NOTE: Your network interface card will likely have a different name.

3.Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and click on “Properties” to assign an IP address to your computer (this will disable “obtain an IP address automatically”):

IP Address : 10.10.6.101

Netmask : 255.255.255.0

Default gateway : 10.10.6.1

4. Click <OK> or <Close> to exit the various dialog boxes.

As long as you have not modified the TCPCONFIG 1 macro in the sample program, enter the following server address in your Web browser to bring up the Web page served by the sample program.

http://10.10.6.100

Otherwise use the TCP/IP settings you entered in the TCP_CONFIG.LIB library.

This sample program does not exhibit ideal behavior in its method of writing to the NAND flash. However, the inefficiency attributable to the small amount of data written in each append operation is offset somewhat by the expected relative infrequency of these writes, and by the sample program's method of “walking” through the flash blocks when appending data as well as when a log is cleared.

•NFLASH_ERASE.c—This program is a utility to erase all the good blocks on a NAND flash chip. When the program starts running, it attempts to establish communication with the NAND flash chip selected by the user. If the communication is successful, the progress in erasing the blocks is displayed in the Dynamic C STDIO window as the blocks are erased.
