2.產(chǎn) 品 詳 情 資 料：
WINGREEN 034STM4-00-200-RS連電纜暴露在外部噪聲源中，可能會導(dǎo)致信號導(dǎo)體和電纜負載端電路公共端之間的電壓差超過±1V? 用電阻器代替發(fā)電機。有必要盡量減少對其他信號的干擾。可能需要反轉(zhuǎn)信號（例如，通過反轉(zhuǎn)電纜對可以實現(xiàn)正極性標記到負極性標記）。WINGREEN 034STM4-00-200-RS表A-8和A-9中列出了適用于WINGREEN 034STM4-00-200-RS的EIA-485接口變送器（發(fā)電機）和接收器（負載）參數(shù)。接地。接地引腳的使用是需要考慮的一個重要問題。有兩個引腳標記為GND。針腳7是信號接地，必須連接到遠程設(shè)備才能完成電路。針腳1是底盤接地，但必須小心使用。機箱通過電源線中的綠色導(dǎo)線連接到電源接地，必須按照電氣規(guī)范進行連接
The interconnection cable is exposed to extraneous noise sources that may cause an unwanted voltage in excess of ±1V measured differentiallyWINGREEN 034STM4-00-200-RS between the signal conductor and circuit common at the load end of the cable, with a 50? resistor substituted for the generator.It is necessary to minimize interference with other signals.Inversion of signals may be required (e.g., plus polarity MARK to minus polarity MARK may be achieved by inverting the cable pair). EIA-485 interface transmitter (generator) and receiver (load) parameters applicable to the WINGREEN 034STM4-00-200-RS are listed in Tables A-8 and A-9.Proper Grounding An important subject to consider is the use of ground pins. There are two pins labeled GND. Pin 7 is the signal ground and must be connected to the distant device to complete the circuit. Pin 1 is the chassis ground, but it must be used with care. The chassis is connected to the power ground through the green wire in the power cord and must be connected to be in compliance with the electrical codeWINGREEN 034STM4-00-200-RS
