产品描述

34-0394001 是 Delta Tau 数据系统 （PMAC 2） ACC 28A 微型模数转换器 PCI（外围组件互连）。 这是一个复杂的电路板，具有两个连接的辅助板和大量的表面布线。

34-0394001的主板一端标记为“PCI 5V 32位原型板，P/N 34-0394001”。 电路板在每个角落都经过工厂钻孔，用于安装选项。电路板表面印有圆线，然后将其分解成一个叠加网格，该网格在电路板表面上巧妙地标记，其坐标注释位于电路板边缘（Y01/Y11/Y31、X51/x61/x71/x81/x91/x101）。该板有一个连接器以 5 度角连接到一个短边。该连接器通过两个螺钉安装连接到电路板表面。数十根红色、橙色、黄色和黑色电线从连接器穿过两个辅助板上的接线端子。主板有一排从一条长边延伸的导电针脚，每个针脚都有四个指定给每个针脚的圆形开口，并标记（通常两次）。其中一些标签是+<>V，接地，停止#，Trdy#和TDI。

连接到34-0394001板表面的两个辅助板本质上是彼此的重复。端子条位于每块板的前面。两块板都装有两个稳压器，表面还有五个电位计。这些板同时使用碳复合电阻器和金属膜电阻器。电容器往往由陶瓷材料制成。每块板都有多个电阻网络阵列、多个集成电路和一个用于连接带状电缆连接器的垂直引脚连接器

34-0394001 is a Delta Tau Data System (PMAC 2) ACC 28A Micro Analog to Digital Converter PCI (Peripheral Component Interconnection). This is a complex circuit board with two connected auxiliary boards and a large amount of surface wiring.

One end of the motherboard of 34-0394001 is marked as "PCI 5V 32-bit prototype board, P/N 34-0394001". The circuit board is factory drilled in every corner for installation options. The surface of the circuit board is printed with circular lines, which are then decomposed into a superimposed grid cleverly marked on the surface of the circuit board, with coordinate annotations located at the edges of the circuit board (Y01/Y11/Y31, X51/x61/x71/x81/x91/x101). The board has a connector connected to a short edge at a 5 degree angle. The connector is installed and connected to the surface of the circuit board through two screws. Dozens of red, orange, yellow, and black wires pass through the wiring terminals on the two auxiliary boards from the connectors. The motherboard has a row of conductive pins extending from a long edge, each with four circular openings assigned to each pin and marked (usually twice). Some of the labels are+<>V, grounded, stop #, Trdy #, and TDI.

The two auxiliary boards connected to the surface of the 34-0394001 board are essentially duplicates of each other. The terminal strip is located at the front of each board. Both boards are equipped with two voltage regulators and five potentiometers on the surface. These boards use both carbon composite resistors and metal film resistors. Capacitors are often made of ceramic materials. Each board has multiple resistive network arrays, multiple integrated circuits, and a vertical pin connector for connecting ribbon cable connectors
