VEDA HCT User Manual 1 Introduction The software “VEDA HCT” you are using is a new configuration software product developed by our R&D team for VEDA HMI. It was produced with more than ten years of technical experience and accumulation based on sufficient practices on Human Machine Interface product development and field actualization. We believe you will feel our specialization and concentration when you use this software. Thank you! 2 Quick start 2.1 Electrical connection of the screen 2.1.1 Connect to the power supply Fig. 1 2.1.2 Connect to the computer Fig.
2 2.1.3 Serial port connection The serial port of the screen is a standard DB 9-pin port supporting communication modes RS232/485/422, as shown in Fig. 3.Different screen types are integrated with different quantities of serial ports, and please refer to the Description for Communication Connection for the detailed connecting method. 1 The rated voltage of the screen is DC18~28V, and DC24V power supply is recommended. The interface is at the back, as shown in Fig. 1, the “24V+” is connected to “DC24V”, the “24V-“ (or "0V") is connected to “GND”. If the field is involved with a high interference, a highly reliable earth must be connected to the “FG” port. (Note:
FG- Frame Ground, the reference grounding for the metal shell frame and the DC end.) The screen can be connected to the computer only via a USB data cable for project uploading and downloading, as shown in Fig. 2.The communication with computer can be realized when it is connected to the “USB SLAVE” end. The USB communication drive can be installed by the system in default during software installation, or the drive can be manually installed if it is damaged. The drive file is saved in the installation directory: “C:\ProgramFiles(x86)\VEDA HCT\VEDA HMI Configuration Tool 2.x\Driver”.
