straight cable with the proper connectors
(Campbell Scientific SC25PS or equivalent for
a 25 pin serial port configured DTE).
OV3.3.2 ESTABLISHING COMMUNICATION
WITH THE CR10
Communication software is available for most
computers having a serial port. Campbell
Scientific's PC208 Datalogger Support
Software is available for IBM PC/XT/AT/PS-2's
and compatibles. The software must be
capable of the following communication
protocol:
1. Configuring an asynchronous serial port for
8 Data Bits, 1 Stop Bit, no Parity, and Full
Duplex at baud rates of 300, 1200, or 9600
baud.
2. Transmitting characters typed on the
keyboard out through the serial port.
3. Displaying characters/data received
through the computer's serial port.
Once the computer is functioning as a terminal,
initiate communications by sending the CR10
several carriage returns for the CR10 to match
the baud rate and respond with "*". Enter the
7H command to enter the Remote Keyboard
State. At this point, the CR10 can be controlled
using the Keyboard Commands described in
Section OV4. For additional information on
communications, see Section 6.7.

OV4. PROGRAMMING THE CR10

A program is created by entering it directly into
the datalogger or on a computer using the
PC208 Datalogger Support Software program
EDLOG. This manual describes direct
interaction with the CR10. Work through the
direct programming examples in this overview
before using EDLOG and you will have the
basics of CR10 operation as well as an
appreciation for the help provided by the
software. Section OV4.5 describes options for
loading the program into the CR10.

OV4.1 FUNCTIONAL MODES

CR10/User interaction is broken into different
functional MODES (e.g., programming the
measurements and output, setting time,
manually initiating a block data transfer to
Storage Module, etc.). The modes are referred
to as Star (*) Modes since they are accessed
OV-12
by first keying *, then the mode number or
letter. Table OV4.1-1 lists the CR10 Modes.
