Wiring panel and terminal functions

The GRANITE 9/10 wiring panel provides ports and removable Closedterminals Point at which a wire (or wires) connects to a wiring panel or connector. Wires are usually secured in terminals by screw- or lever-and-spring actuated gates with small screw- or spring-loaded clamps. 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: ‪

  • Pulse counting
  • Communications
  • Digital I/O
  • Power input
  • Power output
  • Power ground

NOTE:

Conflicts can occur when a control port pair is used for different instructions (TimerInput(), PulseCount(), SDI12Recorder(), WaitDigTrig()). For example, if C1 is used for SDI12Recorder(), C2 cannot be used for TimerInput(), PulseCount(), or WaitDigTrig().

C terminal voltage levels are configured in pairs. The default voltage output from C terminals is 5 V. Use the PortPairConfig instruction in CRBasic to configure a C terminal pair to output 3.3 V.
