Connect Sonde 2.12 Data Collection Platform (DCP) This signal output adapter (DCP-SOA #599800) allows users to connect an EXO sonde to a Data Collection Platform as well as power it via an external 12 V DC source (not included). Users wire a sonde cable with flying leads into one side of the SOA and an SDI-12 /RS-232 output and power source into the other. Mount the SOA in a humidity-controlled enclosure using the following recommended hardware, and never attempt to perform electrical work beyond your experience. 1 Configure sonde. Using KOR software, go to the Deploy menu and choose to deploy by opening a template or starting a custom deployment. Click Edit, then go to the SDI-12 tab and select your parameters and the SDI address. The sonde’s default address is zero (0). Click to save with one of these options: Save, deploy, start logging; Save, deploy, no logging; Save only. Refer to Section 4.4 KOR Software for more details. 2 Route cable. Determine the sonde cable routing to the DCP, and protect the cable from chafe damage and impact. Route the cable through a sealing gland into the DCP, and ensure that the seal is air-tight and water-tight. 3 Mount SOA. on reverse 3M 3M Users can mount the SOA horizontally or vertically either by the screw slots on the sides of the SOA or with the included 3M adhesive strips. The screw slots were designed to accept #4 wood screws but may accept other types and sizes. If the user opts to use adhesive strips, first clean the application surface with a 50:50 mixture of isopropyl alcohol and water, then mount them in temperatures between 21° and 38°C (70˚ and 100˚F) and allow the bond to cure for 72 hours if possible before attaching wires. pg | 41 4 Connect flying lead cable to sonde. Press in the male 6-pin connector, then screw down the retaining collar. Attach the cable’s strain relief to the sonde’s bail with a carabiner. The cable’s strain relief is designed to capture the sonde in case of failure of the connector. 1 1 0 14 2 1 1 6 20 8 A 5 Prepare wires. Always follow proper safety precautions when performing electrical work. Properly strip the ends of the wire. Remove 0.25 inches of insulation from each wire then twist the bared strands together. All wires should be 18-24 AWG and are not included with the SOA. 6 Insert wires into SOA. Loosen the clamping screw with the supplied screwdriver, insert the indicated wire into the terminal strip, and tighten the clamping screw back down onto the exposed wire end. Ensure that all strands are inserted to avoid short circuits. Take care not to strip the slots in the heads of the screws. • Connect DCP signal ground to SOA SDI ground terminal (recommend black wire) • Connect DCP SDI-12 data terminal for SOA SDI-12 terminal (recommend violet wire) • Connect DCP output ground terminal to SOA power ground terminal (recommend black wire) • Connect DCP 12 VDC output to SOA 9-16 VDC input terminal (recommend red wire). NOTE: Due to the tight accessibility of many enclosures, it may be more practical to complete Step 6 (Wiring) prior to Step 3 (Mounting). pg | 42 Voltage The sonde is designed to run with 12-volt batteries, with supply voltages between 9 and 16 V DC. These systems should be directly powered by a sealed battery or installed as part of a remote solar system. Power the SOA through a 1-amp slow-blow fuse for protection. Remove the fuse until all wiring is completed. When used with a solar system always ensure use of 12-volt solar regulator. Never connect the sonde directly to solar panel; voltages above 16.5 volts will cause the sonde to shut down and excessive voltage will permanently damage the sonde and is not covered under warranty.
