Upgrading the Ethernet Unit/Ethernet Plug-in
The operating system within the Ethernet unit may be upgraded, when required, by connecting a PC running
the ToolBox System Downloader to the Ethernet unit (see figure below). The D-type (female) adapter
should be configured as described in the table below. This adapter and cable directly connects to an RS-232
connector on the PC. Set the data speed for the ToolBox to 19200 bps.
To upgrade the Ethernet Plug-in, the Ethernet Plug-in board should be relocated to an empty Ethernet unit
box and be upgraded like an Ethernet unit.
Note that the number shown in the figure next to an item is the kit or part number.
