In the instruments industry, the traditional 4 20 mA analog transmitters are upgrading to the fieldbus with digital communication. HART fieldbus communication has digital communication capability with compatible analog signal. HART MODEM is a necessary and convenient tool for the analog products upgrading and signal exchanging in the control plant. We provide two kinds of HART modem. HART-RS232 is the converter for HART signal to RS-232 signal. HART-USB is the converter for HART signal to PC virtual series port.
Product characteristic:
According to the HART physical layer specification
Isolated transformer prevents the influence of earthing.
Voltage signal modulator/demodulator
Low power consumption designation
Powered by series port or USB port
Interface Type: DB9 female mount
Ambient Temperature: 0 ~ 50 °C
Compressive Strength :500 V AC HART bus and serial port (UART,USB)
HART-RS232 is the protocol converter between HART device and configurator on PC.
The figure above is a sample basic case. To connect multiple HART device, please connect the other devices parallel with the Transmiter. Please note that the power should support multiple devices and the terminator should be set in the middle of the power and parallel point.
HART-RS232 is a HART MODEM with voltage modulator/demodulator. To communicate with a HART device, please connect the clincher of HART port of HART-RS232 to the two terminals of the network adaptor resistance or the power of HART device. To communicate with a PC, please connect the other port of HART-RS232 to the series port of PC.
The USB driver installation program should be run for HART-USB. The driver provides a virtual series ports for HART configurator software.
The indication light shows the state of modem. Green LED indicates the power is working well and the modem is sending data. Red LED indicates the modem is receiving data

Ultra-short Throw LED Smart Projector
Interactive projector is mainly used in Education and Business field currently. LED light source been applying to P9, avoiding of bulb consumable items problems, which solved the biggest maintenance problem of traditional projector. Ultra short focus, which avoid the Shadows shade problem of short and long focus projector. P9 pushes all-in-one interactive projector applying to Education and Business into a much more higher level because of its built- in Android system(Windows Optional)/interactive function and strong 2.1 sound speaker.
