HONEYWELL 51401551-301接口特性在為DTE和DCE設(shè)備之間的串行二進制數(shù)據(jù)交換指定參數(shù)時，EIA-530標(biāo)準(zhǔn)假定使用平衡線路，遠(yuǎn)程環(huán)回、本地環(huán)回和測試模式線路除外，這些線路是單端的。在以下任何一種情況下，平衡線路數(shù)據(jù)交換通常優(yōu)先于非平衡線路數(shù)據(jù)互換：? 互連電纜過長，無法進行有效的不平衡操作。? 互連電纜暴露在外部噪聲源中，HONEYWELL 51401551-301可能會導(dǎo)致在電纜負(fù)載端的信號導(dǎo)體和電路接地之間差分測量的電壓超過±1V? 用電阻器代替變送器。? 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(biāo)記到負(fù)極性標(biāo)記）。表A-5和A-6列出了適用于MVME162FX的EIA-530接口發(fā)射機和接收機參數(shù)。HONEYWELL 51401551-301
Interface Characteristics In specifying parameters for serial binary data interchange between DTE and DCE devices, the EIA-530 standard assumes the use of balanced lines, except for the Remote Loopback, Local Loopback, and Test Mode lines,HONEYWELL 51401551-301which are single-ended. Balanced-line data interchange is generally employed in preference to unbalanced-line data interchange where any of the following conditions prevail: ? The interconnection cable is too long for effective unbalanced operation.HONEYWELL 51401551-301? The interconnection cable is exposed to extraneous noise sources that may cause an unwanted voltage in excess of ±1V measured differentially between the signal conductor and circuit ground at the load end of the cable, with a 50? resistor substituted for the transmitter. ? 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-530 interface transmitter and receiver parameters applicable to the MVME162FX are listed in Tables A-5 and A-6.HONEYWELL 51401551-301
