US TR-108 light isolation interface transmitter. Compatible RS-232C, RS-422, RS-485 standard, can transfer signal end RS232 signal to balance difference RS-422 or RS-485 signal, inner photo electricity isolation transmitter and DC/DC direct current transmitter, can supply 3500V isolation voltage, double – quick twinkling voltage suppresser (TVS) can effectively restrain lightning and ESD, can supply 600W per wire thunder surge protective, can effectively prevent thunder and shear earth interfere. RS-232 port can connect with PC, IPC or laptop with a DB9 female connector. RS-422, RS-485 port can connect using a 7 bit connection extremity. Because RS-485 support 2 wire semi duplex, that is to say RS-485 only has 2 circuitries (not only sending data, but also receiving data), handshake signal (e g RTS, Request To Send) normally control the direction of the data sending,
USTR-108 inner circuit can automatically feel the data stream direction, and automatically switch control, can conveniently compose a RS-485 work net no need any handshake signal. Such RS-485 control is full transparent, no need do any revise to the previous RS232 working.
US TR-108 can provide dependable connection to point to point or point to more point communication. Point to more point can allow to connect with 32 pcs RS-422 or RS-485 interface equipment. Data communication rate from 0 to 115.2 KBPS, 3 power supplies and data flux indicator light can indicate the failure instance, support the communication mode RS-232C to RS-422, RS-232 to RS-485 transfer point to point, or point to more points com.
