SUPPORTED PRODUCTS Model Number of Ports -------------------------------------- PortServer 16 PortServer II 16 PortServer II Rack 16 Digi One RealPort 1 Digi One IA 1 Digi One TS 1 PortServer TS 2 PortServer TS 4 PortServer TS 8 PortServer TS 16 PortServer TS 16 Rack 16 EtherLite 2 2 EtherLite 8 8 EtherLite 16 16 EtherLite 32 32 EtherLite 80 8 EtherLite 160 16 EtherLite 162 16 3. KNOWN LIMITATIONS The service does not support software flow control characters (Xon and Xoff) set to null (0x00). The service does not support IOCTL_SERIAL_XOFF_COUNTER. The PortServer generates receive data errors when running 16 ports full duplex at 57600 baud. Changing the baud rate of a serial printer requires deleting the printer device and then re-adding the device with a different baud rate. This is a Print Manager limitation in Windows NT 4.0. If one plans to use the RealPort service with serial printers, one has to reboot the system after device installation or after renaming ports to see the new ports listed in the Print Spooler's list of available ports for printing. This is a known limitation of the Print Spooler, which does not detect changes in the list of available ports automatically. 4. UPGRADING REALPORT UPGRADING FROM AN ETHERLITE DRIVER ---------------------------------- If one has previously installed the EtherLite driver for an EtherLite device (EtherLite 2/8/16/32/80/160/162), please follow these necessary steps to upgrade to the current RealPort service: a. Uninstall the old EtherLite driver and reboot the system. b. Update the EtherLite firmware using the DGIPSERV utility, which is included in the driver package. One can download the latest firmware files from the Digi Support Web site, http://support.digi.com. c. Install the new RealPort Service. UPGRADING AN EXISTING REALPORT SERVICE -------------------------------------- To upgrade a previously-installed RealPort service to the new service, please follow these steps. Note that the "Update" feature available from the Services Tab of Network Neighborhood Properties is not supported -- instead, one must first uninstall the existing RealPort service and then install the new RealPort service: a. First, navigate to the Services Tab: o From the Desktop, right-click "Network Neighborhood" o Select "Properties" o Click on the tab marked "Services" b. Next, uninstall the existing RealPort service: o Select "Digi RealPort Service" o Click "Remove" o Click "Yes" o Click "Close" to dismiss the Network window o Click "Yes" to restart Windows c. Finally, install the new RealPort service: o Navigate to the Services Tab (see a. above) o Click "Add" o Click "Have Disk..." o Enter the path to the new RealPort service files o Click "OK" o Click "OK" d. Follow any other instructions to complete the installation. 5. ADDITIONAL NOTES On-line help is available when you install the product.
