GM-10017-B is a port-powered converter with optoelectronic isolation. It complies with RS-232C and RS-485 standards; it converts RS-232 signal to a balanced differential RS-422 or RS-485 signal. The built-in optoelectronic isolator can withstand up to 2,500Vrm isolated voltage; the fast instant voltage restraint is designed to protect the RS-485 interface; it adopts advanced TVS (TRANSIENT VOLTAGE SUPPRESSOR) instant voltage restraint; normally, TVS tube is in high impedance state; but when both sides of TVS tube suffer from high power voltage spikes, the voltage restraint will quickly lower the impedance from both sides, and absorb the large current; with this, the voltage on both sides are at a fixed value, which protects the component of circuit damage. This voltage restraint provides 600W on each wire with lightning and ESD protection, surge, and instant overvoltage protection on circuit; the tiny interelectrode 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 DB9 male connector as output. This converter has built-in zero delay auto receiving and transmitting conversion with unique auto I/O circuit control data flow direction without any handshake signal (RTS, DTR); there is no need for a jumper wire setting for half-duplex (RS-485) mode, its just plug & play.
GM-10017-B optoelectronic isolated port-powered converter provides a connection for point to point, and point to multipoint communication. For point to multipoint mode, each converter is allowed to connect 32 RS-485 devices with supported baud rate up to 300-115.2Kbps.
