other charge control parameters normally not of interest to the user can be
viewed. See Section 6.3, RS-232 Interface, for an in-depth explanation.
The advantage of SDI-12 over RS-232 is that many sensors can share a single
datalogger SDI-12 port, whereas, RS-232 is limited to one device per port. The
advantage of RS-232 over SDI-12 is that its speed can be faster than SDI-12.
Datalogger programming for SDI-12 is usually simpler than programming for a
RS-232 device.
All PS200/CH200 serial communications are via its four-pin COMM
connector. The PS200/CH200 will detect which of the four kinds of serial
communications is being used and will reconfigure itself accordingly.
Some configurations of the PS200/CH200 can also be done via a datalogger
using RS-232 or SDI-12 commands but require knowledge of CRBasic
programming. See Section 6.2, SDI-12, for SDI-12 programming examples
and Section 6.3, RS-232 Interface, for datalogger RS-232 programming.
6.1 Configuring the PS200/CH200 Using Campbell Scientific
Device Configuration Utility (DevConfig)
The easiest way to configure the PS200/CH200 is using Device Configuration
Utility and a computer. The only way to update the operating system in a
PS200/CH200 is via Device Configuration Utility.
To use Device Configuration Utility the PS200/CH200 must have power and a
Campbell Scientific RS-232 interface cable (item #20770) (see FIGURE 6-1).
Some key features of DevConfig include:
• Supports direct serial connections between the PC and devices.
• Sends operating systems to supported device types.
• Provides a reporting facility where a summary of the current configuration
of a device can be shown on the screen and printed. This configuration
can also be saved to a file and used to restore the settings in the same or a
replacement device.
• Help for DevConfig is shown as prompts and explanations on its main
screen.
• Updates to DevConfig are available from Campbell Scientific’s web site,
www.campbellsci.com/downloads . These may be installed over older
versions.
• All screen shots used in this manual are from Device Configuration Utility
version 2.04.
Before opening DevConfig, close other software on the computer
that uses the computer’s serial (COM) ports (e.g., LoggerNet,
PC400, or PC200W). NOTE
