1.4. Data transmission
The photometer can use 4 different communication protocols to send its data from the
CU.
• PC data transfer using a RS232 link to an acquisition PC. (Default data
transmission). The PC is not provided.
• Satellite data transfer using a DCP transmitter module. The proper way to set
the module is explained in the Installation chapter.
• USB link for punctual connections.
• Communication over GPRS.
2 Installation
2.1. Installation site recommendations
The site should be chosen carefully in order to comply with the following conditions:
• Easy access to facilitate the weekly maintenance of the device.
• The device should be installed in a clear area where it has the largest possible
field of view so that it can track the sun from sunrise to sunset (no buildings,
trees, cables…).
• Less than 100m cable distance to a PC (for RS232 link connection).
• A support where it can be strongly fixed so that the system is stable
(preferably the tripod).
2.2. Hardware installation and setup
In this description, notions on how to manually control the photometer via the CU are
necessary, it is recommended to read chapter 3 and 4 to have a better overview of
what is done when installing the system.
However, the following instructions are detailed enough so that it is not mandatory to
read the 2 chapters cited above.
If the tripod system is not used, skip to part 2.2.4.
