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

Either the CABLE4CBL cable or MUXPOWER cable may be used to connect

the control terminals. The biggest difference between these cables is that the

CABLE4CBL has a Santoprene jacket and the MUXPOWER has a PVC

jacket. The Santoprene jacket is more rugged.

The CR5000, CR3000, CR800, CR850, CR1000, CR23X, CR10(X), 21X, and

CR7 dataloggers connect to the AM16/32B 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

AM16/32B 12V and ground terminals. One control port is required for

clocking and a second control port for reset. The cable’s shield is grounded on

both ends as illustrated in Figure 3.
