1.3. Control Module
The control module is the interface between the RS485 sensor bus and data communication links. It
contains a display, a SD data card which logs data, a RS232 serial connector for external
communication, a bus connector for internal communication with the sensor modules and a cable
connector for the Sensiron Humidity and Temperature sensor (if fitted).
The Dust Profiler is supplied with a RS232 to USB adapter fitted between the Control Module and an
external USB socket fitted at the base of the enclosure. This enables the user to perform a wide range
of functions over the USB connection, without needing to open the enclosure door, such as data
logging and various system checks using the supplied Aeroqual Dust Profiler PC software.
Note 1: The driver for the RS232 to USB adapter is in the USB stick which comes with the
instrument.
Note 2: The power to sensor and alarm relays are also attached to the control module base
plate.
