Release Notes PN 93000464 Digi One IA RealPort 82000770_A July 19, 2002 NOTE: When upgrading to a new version of firmware for your Device Server, please ensure that you are running the most recent POST (Power-On-Self-Test) code as well. For the 82000770_A firmware release this would be the 82000779_A POST. Instructions for upgrading the POST are in ADDITIONAL INFORMATION. INTRODUCTION This is a production release of firmware for the Digi One IA RealPort SUPPORTED PRODUCTS Digi One IA RealPort ENHANCEMENTS The 82000770_A release adds support for Industrial Ethernet and Serial protocols and protocol routing to the Digi International product line. Supported protocols include: DF1 full duplex DF1 half duplex Modbus RTU/ASCII/TCP Omron serial protocols Hostlink FINS Compoway/f Allen Bradley Ethernet EtherNet/IP User-defined The ability to encapsulate the serial protocols over Ethernet is also provided for both TCP and UDP sockets. The firmware also incorporates some changes to reduce the latency of packets transmitted over both the serial and network interfaces. These changes are active when the 'optimize' setting in the 'set config' command line is set to 'latency'. The old behaviour is available with the 'throughput' setting. Another new feature in this firmware is RTS toggle. This feature when enabled with 'set flow rts=toggle' will cause RTS to be active when data is transmitted and inactive otherwise. The optional settings for 'set flow' pre-delay and post-delay determine the delays before transmitting and after transmitting data that RTS is held active. These values can be viewed with 'set flow show=rtstoggle'. ADDITIONAL INFORMATION A TFTP server will be required for the following steps: Upgrading the POST and EOS -------------------------- If you are unsure which versions of POST code you have, we recommend you upgrade to the most recent version. The most recent POST code, 82000779_A, is located on the Digi support web site http://support.digi.com. You can verify which version of the POST you have with the 'show versions' command. If the version listed for the POST is not 82000779_A, please upgrade. This can be done from the OS with the command: boot load-post=:82000779A.bin A reset is necessary to allow the new POST to run. boot action=reset Upgrade the EOS with the command: boot load=:82000770_A.bin The unit should be reset after the EOS upgrade as well. HTTP upgrade of EOS -------------------- The EOS may also be upgraded from the WebUI configuration interface. From the machine containing the image file to which you will be upgrading, navigate the WebUI menus to "Admin\HTTP Upgrade" and enter the path and filename into the text box on the screen and click submit. First boot following upgrade ---------------------------- If you are upgrading to this release of the firmware, it may take several minutes following a reboot of the system for it to become responsive. This is due to configuration settings being initialized in SSH to provide secure connections. This delay will occur on any occasion when the SSH configuration data is reset. --------------------------- KNOWN ISSUES When the device is set to devtype 'ia' modem signals will not be reported. This is by design, due to the ability of the Digi One IA RealPort to provide an IA connection to multiple masters using a single serial port.
