SDI-12 Cable Wiring
There are two SDI-12 cables available from YSI for use with the ProSample P-12 and ProSample PM-12.
SDI-12 Cable with Flying Leads
One end of item # 630146 has flying leads for connecting to an SDI-12 device or a Signal Output Adapter for the SDI-
12 device (
e.g.
YSI EXO1 and YSI EXO2). The other end of this cable is connected to the SDI-12 input on the ProSample
P-12 or ProSample PM-12.
Please refer to the wire colors below when connecting the flow signal cable to the digital and/or analog device, as well
as the manual for your SDI-12 device .
SDI-12 Cable with EXO3 Connector
620145 cables have all of the connections necessary to directly connect a YSI EXO3 directly to the ProSample P-12 and
ProSample PM-12. Therefore, no wiring is needed. These cables are offered in lengths of 2, 4, 10, 15, and 33 meters.
Connection of the Flow Signal Cable and/or SDI-12 Cable
There are two connectors on the side of the ProSample near the peristaltic pump. The top connector is for the flow
signal cable, while the bottom connector (ProSample P-12 and ProSample PM-12 only) is for connection of an SDI-12
cable.
