+@* Degree of roast analysis configuration.
+
+\noindent \pn{} 1.9 adds support for communicating with the Javalytics
+JAV-RDA-D degree of roast analyzer from Madison Instruments, and with it, the
+ability to track roast color data. There are some settings that are specific to
+this device which need to be configurable, but saving roast color data need not
+be manufacturer specific and manual data entry options should be provided for
+people choosing devices without a communications option.
+
+If support for additional devices is added in the future, these settings may
+need to be redesigned to better support competing options. There is also an
+assumption that only one of these machines will be in use at one time from any
+given instance of \pn{}.

+@ There are several options available for configuring supported hardware, but
+for the initial implementation the preference is to keep things as simple as
+possible, adding support for additional features only as requested. As such,
+the current options are whether to communicate with external hardware at all,
+the IP address of the device, and the scale to request when taking measurements
+from \pn{}.
+
+Testing indicates that when batch numbering is enabled, it is still better to
+not send an explicit batch number to the device. Sending a number that is equal
+or lower than one used previously results in a silent failure while not sending
+a number when this feature is enabled results in the next number in the
+sequence being chosen automatically.
