SECTION 9. INPUT/OUTPUT INSTRUCTIONS

9-15

PARAMETER 3. LOCATION

This parameter determines the starting input

location for the 'nn' values to be returned to the

recorder. The 'M' or 'M1-M9' command issued

by the SDI-12 recorder determines if the starting

location is actually that specified in Parameter 3

or a multiple of 'nn' past Parameter 3.

Starting input location = Parameter 3 + (nn∗x),

where nn is specified in Parameter 2, and, x is

the number following the 'M' sent by the SDI-12

recorder (1-9).If the 'M' command is sent by the

recorder x = 0.

Results of Instruction 106

The sensor CR510 will return a set of input

locations in response to the M or M1..M9

command sequence. The set of Locations

returned is determined by Parameters 2 and 3

of Instruction 106.

The three values, sent in response to a V

command sequence, indicate the status of the

sensor CR510. The first and second values are

from the ∗B mode of the sensor CR510, giving

the number of watchdog errors (E08) and the

number of table overruns that have occurred.

The third is a signature of the sensor CR510

memory. This signature is created by the same

technique that the Instruction 19 (Signature)

uses.

In response to an I command, the CR510 sends

the string 'AVVCAMPBELLCR510 OS' where A

is the sensor address, VV is the SDI-12 version

number, OS is the CR510 operating system

number.

*** 114 SET TIME ***

FUNCTION

Instruction 114 can be used to set the CR510

clock from values in input locations.

PARAM. DATA

NUMBER TYPE DESCRIPTION

01: 2 Option code:

0 set time with

hr,min,sec with

values in 3 input

locations.

1 set time with

day,hr,min,sec

using 4 input

locations.

2 set time with

yr,day,hr,min,sec

using 5 input

locations.

02: 4 Input location number

*** 117 READ DATALOGGER ID ***

FUNCTION

Instruction 117 stores the datalogger ID into an

input location. The datalogger ID is set in the

∗D mode with Command 8 (Section 1.8.4).

PARAM DATA

NUMBER TYPE DESCRIPTION

01: 4 Input location number

*** 130 Error Monitor ***

FUNCTION

Stores an error count or status information from

*B into an input location. Indexing the option

code will cause the instruction to store the value

into an input location and then clear the *B

value. This is designed to assist with

troubleshooting and to alert users of possible

problems.

PARAM DATA

NUMBER TYPE DESCRIPTION

01: 2 Option Code (Index (--) to

reset error count after

reading)

02: 4 Input Location

Option Codes:

0 Read Watchdog or E08s Errors

1 Read Table Overruns

2 Read Low 12V Detection

3 Read Lithium Battery Voltage Level

(Indexing does nothing)

4 Read Flash (for CR510-1M or CR510-

2M) Errors
