2.产 品 详 情 资 料：
HONEYWELL 51401551-301接口特性在为DTE和DCE设备之间的串行二进制数据交换指定参数时，EIA-530标准假定使用平衡线路，远程环回、本地环回和测试模式线路除外，这些线路是单端的。在以下任何一种情况下，平衡线路数据交换通常优先于非平衡线路数据互换：❏ 互连电缆过长，无法进行有效的不平衡操作。❏ 互连电缆暴露在外部噪声源中，HONEYWELL 51401551-301可能会导致在电缆负载端的信号导体和电路接地之间差分测量的电压超过±1VΩ 用电阻器代替变送器。❏ 有必要尽量减少对其他信号的干扰。❏ 可能需要反转信号（例如，通过反转电缆对可以实现正极性标记到负极性标记）。表A-5和A-6列出了适用于MVME162FX的EIA-530接口发射机和接收机参数。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 50Ω 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
