The CR6 wiring panel provides ports and removable terminals for connecting sensors, power, and
communications devices. It is protected against surge, over-voltage, over-current, and reverse
power. The wiring panel is the interface to most data logger functions so studying it is a good
way to get acquainted with the data logger. Functions of the terminals are broken down into the
following categories:
l Analog input
l Pulse counting
l Analog output
l Communications
l Digital I/O
l Power input
l Power output
