5.6 Connecting more than One Sonde to a Field Station
Some applications may require more than one sonde to be connected to a single field station. In
order to communicate with multiple sondes, they each must be assigned unique SDI-12
addresses. The default address in a new sonde is 0, but you may assign any one digit address
from 0 to F (0 to 9 and A to F) for a total of 16 different sondes connecting to a 6200 DCP.
Refer to section 3.4 for changing the SDI-12 address.
Since there is only one MS-8 Sonde connector at the 6200 DCP, some combination of breakout
and junction boxes will be necessary for multiple sonde configuration. A 6 ft (2 m) patch cable
(P/N 6507) terminates in an MS-8 at one end and “flying leads” at the other. There are three
configurations that describe the basis for all configurations. See the descriptions and figures
below that describe these SDI-12 multi-sonde connections.
IMPORTANT!
Corrosion can cause significant performance problems if moisture intrusion is not
controlled. Make certain that all junction boxes are tightly sealed and that desiccant is
used in all boxes. Always use fresh desiccant when you open and close the 6200 DCP
enclosure or any junction box.
