Documentation LucidControl RTD Input USB Module – Device Setup and Installation

2 Setup and Installation

Fig. 2-1 Schematic of LucidControl RTD input USB module

Fig. 2-1 shows the sketch of the USB RTD Input Module with 4 RTD (Resistance Temperature Detector) inputs (AI0 ~ AI3).

All LucidControl USB IO modules have two connectors, the USB-Connector and the IO-Connector. Because of this the modules are very easy to connect and to set-up.

While the upper USB connector is used for interconnection with the computer, the lower IO-Connector is used for inputs and outputs.

The IO-Connector provides 8 terminals in total – two for each input.

2.1.2 IO Connection

Fig 2.1.2-1 Pt1000 RTD Connection

The LucidControl RT4 module provides 4 channels measuring temperatures of Pt1000 RTDs.
Fig. 2.1.2-1 shows the interconnection of the module with 4 RTDs connected to the IO-Connector.
The terminals 2, 4, 6 and 8 are internally connected to ground.

2.2.4 Ready to Start

Once the module was installed successfully (if it was necessary at all) the green Power LED is switched on signaling that the module is ready for use.

Since the module was preconfigured for standard input mode it can be used without further configuration.
The following examples demonstrate the functionality of the module by using the LucidIoCtrl command line tool.

Windows Examples
For all examples it is assumed that the module is connected to COM1.

Reading the values of all 4 RTD input channels
LucidIoCtrl –dCOM1 –tT –c0,1,2,3 –r [ENTER]
-> CH0:25.000 CH1:25.000 CH2:25.000 CH3:25.000

Linux Examples:
For all examples it is assumed that the module is connected to /dev/ttyACM0.

Reading the values of all 4 input channels
LucidIoCtrl –d/dev/ttyACM0 –tT –c0,1,2,3 –r [ENTER]
-> CH0:25.000 CH1:25.000 CH2:25.000 CH3:25.000

Note:
Obviously the temperatures can only be read if RTDs are connected to the clamps. Otherwise the module returns:
CH0:ERR_OPEN CH1:ERR_OPEN CH2:ERR_OPEN CH3:ERR_OPEN
