+Serial Adapter
+^^^^^^^^^^^^^^
+
+To communicate with the ceilometer there is an ethernet to serial adapter
+attached to it. The "rain01" server communicates to it through a special
+driver from "MOXA" (the manufacturer of the adapter). This driver is
+automatically installed as part of the root accounts crontab. See the
+``scripts/reinstall_ceilo_driver.sh`` script for more information.
