YSI DCP Adapter Wiring for Connection to X2 Data Logger
This article serves as a guide for wiring in a YSI EXO 1 or 2 sonde into a YSI DCP Adapter for connection to an X2 data logger. This configuration typically occurs within a NexSens A50 Junction Box to protect the DCP adapter and flying lead cables from environmental disturbances.
