a. Connect the SC-CPI to the datalogger. Reference FIGURE 6-9,
Datalogger to SC-CPI Connection.
CR3000, CR1000, and CR800 dataloggers require that a SC-CPI
interface the datalogger to the CDM-VW300. Connect 12V, G, C1,
C2, and C3 from the SC-CPI to the corresponding 12V, G, C1, C2,
and C3 ports of the datalogger.
SC-CPI module connects to terminals C1, C2, C3 (not SDM-C1,
SDM-C2, SDM-C3). NOTE
