Einstellen von SDI-12-Adressen auf METER-Digitalsensoren.

Entering SDI­-12
 communication “Transparent” mode

CRBasic (CR200,
 CR1000, 
CR3000, 
etc.)

  1. Connect to the 
data logger by 
clicking 
the “Connect” button on 
the 
LoggerNet toolbar and click 
on “Connect” on the 
”Connect 
Screen.”
  2. Select
 “Tools” 
from 
the top 
menu 
and click on
 “Terminal
 Emulator.”
  3. Click
 the 
”Open
 Terminal” 
button at
 the bottom 
of 
the 
window.
  4. Press
 the “Enter” 
key 
a 
few 
times 
until
 a 
”CRXXXX>” prompt 
appears
 (i.e.,
 CR1000>).
  5. Type “SDI12” 
next
 to
 the
 prompt.
    a. Note:
 The
 data logger 
will
 exit
 this mode 
relatively 
quickly 
so 
if
 things don’t
 respond,
 repeat
 Steps
 4
 and 5
 again.
    b. The
 data logger
 will
 respond with “Enter
 Cx
 Port
 1, 3, 5
 or
 7″
 or
 something
 similar.
  6. Enter
 the 
control 
port
 that 
the 
SDI‐12 
sensor 
is 
plugged 
in
to.
    a. The data logger will 
respond
 with
 “Entering SDI-12
 Terminal”.
  7. Proceed
 to “Setting 
SDI‐12
 sensor
 address”
 section.

Edlog (CR10X, CR23X, etc.)

  1. Connect
 to the
 data logger 
by 
clicking the 
”Connect”
 button
 on the 
LoggerNet
 toolbar,
 and
 click
 
”Connect” 
on the “Connect
 Screen.”
    a. Note: 
In our
 tests,
 you have 
to 
be 
running a
 program
 with the 
SDI‐12
 Recorder
 instruction
 (P105) 
in that
 program to
 allow it to go 
into the 
SDI‐12 transparent
 mode.
  2. Select
 “Tools” from the
 top menu
 and click on
 “Terminal
 Emulator.”
  3. Click the “Open
 Terminal”
 button
 at the bottom of the window.
    a. The terminal wind should say
 “Active,”
 highlighted
 in green at
 the 
top.
  4. Enter “pX” at
 the
 asterisk
 prompt where ‘p’ is the control
 port
 number
 (1‐8)
 attached
 to
 the 
SDI‐12
 sensor.
    a. If
 you don’t see
 an asterisk, press ‘Enter’ and
 one
 should
 appear.
    b. Data logger
 should
 respond: “entering SDI‐12.”
    c. The data logger
 will
 exit
 out
 of
 this
 mode reasonably
 quickly.

 Once 
it
 exits, you
 must
 repeat
 Step
 4.
  5. Proceed to
 “Setting 
SDI‐12
 sensor
 address”
 section.

Setting
 SDI-­12 sensor address

Note: Sensors must be addressed individually so
 only 
ONE
 sensor
 may be
 connected to
 the
 communication port at any
 time
 during addressing.

  1. Connect first SDI‐12 sensor to 
the communication port entered in Step 6
 above.
  2. Query its address by typing: ?!
    a. The 
sensor will return its address such that, 
if its address is “0” then the 
line will read: ?!0.
  3. Assign its new address by typing: 0AX! where 
X is the new address you want to 
assign the sensor.
    a. For 
example, if the sensor was assigned address “2” and you wanted to change 
it to “5,” you would type: 
2A5!
    b. The computer would return 
the new address so the line would look like: 
2A5!5.
    c. Possible addresses for SDI‐12 communication with 
CR Basic type loggers are 
0 through 9, 
a through 
z, and A through Z. With Edlog-
type loggers, only 
addresses 0‐9
 are recognized.
  4. Repeat Steps 2 and 
3 for all sensors you need to address, choosing different addresses 
for each sequential
 sensor.
  5. Once all sensors are 
individually addressed, all communication lines can be connected together at a single node and 
the data logger will address each sensor individually using 
the addresses that we assigned and the appropriate SDI‐12 program.
