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, CR1000, CR23X, CR10(X), 21X, and CR7 dataloggers connect
to the AM16/32 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, CR1000, CR23X and CR10(X) the datalogger 12VDC
supply and ground terminals are connected to the AM16/32 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.
