4. Operation
Subsection 4.1 discusses the terminals that control operation of the
multiplexer. These terminals are located at the left-hand side of the
multiplexer as shown in Figure 1. Subsection 4.2 discusses the use of sensor
measurement terminals.
4.1. The Control Terminals
The CR5000, CR3000, CR800, CR850, CR1000, CR23X, CR10(X), 21X, and
CR7 dataloggers connect to the AM16/32A as shown in Figure 3 (“4x16”
mode). Figure 3 depicts control connections. Measurement connections are
discussed in Section 6. The power, ground, reset, and clock connections
remain essentially the same regardless of datalogger used.
With the CR5000, CR3000, CR800, CR850, CR1000, CR23X and CR10(X)
the datalogger 12 VDC supply and ground terminals are connected to the
AM16/32A 12V and ground terminals. One control port is required for
clocking and a second control port for reset. The MUXPOWER cable (or
equivalent) shield is grounded on both ends as illustrated below.
