HESC-T-015 is a converter which complies with RS-232C and RS-485 standards. It converts single side RS-232 signal to a balanced differential RS-485 signal. The fast transient voltage suppression is designed to protect RS-485 interface. It adopts advanced TVS(TRANSIENT VOLTAGE SUPPRESSOR). Normally, TVS tube is in high impedance state. When both sides of TVS tube suffer from high power impact in a sudden, the voltage suppression will fast lower the impedance from both sides, and soak in big current, thus the voltage on both sides are fixed at pre-determined value which protects the component of circuit from damage. This voltage suppression provides 600W lightening and surge protection for each wire and transient over-voltage protection on circuit which is caused by all reasons. The tiny inter-electrode capacitance ensures high speed transmission for RS-485 ports. RS-232 port connects with RS-232C standard port by DB9 female connector. RS-485 adopts RJ-45 and 4-pin terminal block as output. This converter has built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTU, DTR). It is compatible with current communication software and hardware, no need for setting the previous working mode which is based on RS-232.

HESC-T-015 converter provides connection for point-to-point, point-to-multipoint communication. For point-to-multipoint mode, each converter is allowed to connect 32 RS-485 devices with baud rate 300-115,200 bps. The power and data flow indicators indicate the working status.
