6.4 (Optional) Connect to data logger for
SDI-12 or RS-232 communications
The TX, RX, and G terminals are used for communications. FIGURE 7-3 (p. 23) shows example
SDI-12 wiring and FIGURE 7-4 (p. 26) shows example RS-232 wiring.
NOTE:
Communications with the CH201 is required if the data logger is programmed to collect
information from the power supply. See
Communications (p. 21) for more information.
6.5 Turn on power source
Turn on the charging source power or uncover the solar panel. The green CHG LED should flash
every 4 to 5 seconds, which indicates correct incoming connections and adequate charging
voltage.
6.6 Turn on CH201
Toggle the switch on the CH201 supply to On. Check the voltage of the attached devices by using
a volt meter.
6.7 (Optional) Configure using Device
Configuration Utility
Using Campbell Scientific Device Configuration Utility is the easiest method to configure the
CH201 and the only method to update the operating system. If updating an operating system,
