CR10X MEASUREMENT AND CONTROL MODULE OVERVIEW
The CR10X is a fully programmable datalogger/controller with non-volatile memory and a battery backed
clock in a small, rugged, sealed module. The combination of reliability, versatility, and
telecommunications support make it a favorite choice for networks and single logger applications.
Campbell Scientific Inc. provides four aids to operating the CR10X:
1. PCTOUR
2. This Overview
3. The CR10X Operator's Manual
4. The CR10X Prompt Sheet
PCTOUR is a computer-guided tour of CR10X operation and the use of the PC208 Datalogger Support
Software. Much of the material in this Overview is covered in PCTOUR, available on the web at
www.campbellsci.com.
This Overview introduces the concepts required to take advantage of the CR10X's capabilities. Hands-
on programming examples start in Section OV5. Working with a CR10X will help the learning process,
so don't just read the examples, do them. If you want to start this minute, go ahead and try the
examples, then come back and read the rest of the Overview.
The sections of the Operator's Manual which should be read to complete a basic understanding of the
CR10X operation are the Programming Sections 1-3, the portions of the data retrieval Sections 4 and 5
appropriate to the method(s) you are using (see OV6), and Section 14 which covers installation and
maintenance.
Section 6 covers details of serial communications. Sections 7 and 8 contain programming examples.
Sections 9-12 have detailed descriptions of each programming instruction, and Section 13 goes into
detail on the CR10X measurement procedures.
The Prompt Sheet is an abbreviated description of the programming instructions. Once familiar with the
CR10X, it is possible to program it using only the Prompt Sheet as a reference, consulting the manual if
further detail is needed.
Read the Selected Operating Details and Cautionary Notes at the front of the Manual before using the
CR10X.
OV1. PHYSICAL DESCRIPTION
The CR10X was designed to provide a rugged
sealed datalogger with a low per unit cost.
Some of its distinguishing physical features are:
• The CR10X does not have an integral
keyboard/display. The user accesses the
CR10X with the portable CR10KD
Keyboard Display or with a computer or
terminal (Section OV2).
• The CR10X does not have an integral
terminal strip. A removable wiring panel
(Figure OV1.1-1) performs this function and
attaches to the two D-type connectors
located at the end of the module.
• The power supply is external to the CR10X.
This gives the user a wide range of options
(Section 14) for powering the CR10X.
OV1.1 WIRING PANEL
The CR10X Wiring Panel and CR10X
datalogger make electrical contact through the
two D-type connectors at the (left) end of the
CR10X.
The Wiring Panel contains a 9-pin Serial I/O
port used when communicating with the
datalogger and provides terminals for
connecting sensor, control, and power leads to
the CR10X. It also provides transient protection
and reverse polarity protection. Figure OV1.1-2
shows the panel and the instructions used to
access the various terminals.
