SECTION 9. INPUT/OUTPUT INSTRUCTIONS

9-24

The three values, sent in response to a V
command sequence, indicate the status of the
sensor CR10X. The first and second values are
from the

∗B mode of the sensor CR10X, giving

the number of watchdog errors (E08) and the
number of table overruns that have occurred.
The third is a signature of the sensor CR10X
memory. This signature is created by the same
technique that the Instruction 19 (Signature)
uses.

In response to an I command, the CR10X
sends the string '10CAMPBELL CR10X 001
aaaa' where aaaa is the number from the eighth
window of the

∗B mode.

*** 107 SDM-CSAT3 ***

FUNCTION
This instruction controls and receives data from
CSI’s three-dimensional sonic anemometer
(CSAT3). See the CSAT3 manual for
information on Instruction 107.

Input locations altered: 5 per repetition

*** 108 SDM-UDG01 ***

FUNCTION
This instruction is used to measure the UDG01
Ultrasonic Snow Depth Sensor using control
ports C1, C2, and C3. Air temperature is a
required input for Instruction 108.

*** 110 SDM-GROUP TRIGGER ***

FUNCTION
This instruction is used to synchronize the
measurements of up to 15 SDM sensors that
support the group trigger protocol. The data is
retrieved with the appropriate device specific
instruction. Instruction 110 does not have any
parameters.

*** 113 SDM-SI04 ***

FUNCTION
Instruction 113 communicates with the
SDM-SI04 serial input multiplexer. See the
SDM-SI04 manual for directions.

*** 114 SET TIME ***

FUNCTION
Instruction 114 can be used to set the CR10X
clock from values in input locations.
