PS200/CH200 12 V Charging Regulators
6.3.2 RS-232 Communications with a Campbell Scientific Datalogger
The Campbell Scientific CRBasic commands “SerialOut” and “SerialIn” are
designed for RS-232 communications in general and can be used with a
PS200/CH200 to read battery voltage (V), battery current (A), load current (A),
charge input voltage (V), charge input current (A), temperature (
°C), charge
state, charge source (solar or continuous), and a check battery flag (true or
false).
All PS200/CH200 serial communications are via its four-pin connector. There
are two RS-232 interface cables that can be used to connect a datalogger to the
PS200/CH200.
To use the RS-232 9-pin connector on the face of the datalogger use RS-232
serial cable item# 20770 with an additional null modem cable such as
Campbell Scientific item# 18663.
To use control ports configured as RS-232 serial ports (COM1 – COM4) use
Campbell Scientific item # 25356.
