VISTA F404002A总线接模块，是用于总线扩充的模块，可以扩展成2个回路。

VISTA F404002A总线接模块接线方式为：端口接J8左起第一针，6端口接J8左起第七针，7、8端口接主板7、6端口供电。

总线系统一般由传输线+接口+总线控制器组成，其电气特性为：每根传输线上信号的传递方向和有效电平范围，分为单向总线（单工），双向总线（全双工、半双工）。最基本的电气特性为：在任一时刻，只能有一个方向的信息流动，不允许有相向行为。可以一发一收，一发多收；不能多发一收，多发多收。F404002A挂接在总线上的主设备，在任意时刻只允许有一个主设备向总线上发送数据。

总线系统按照传递信息的不同被分为三类：

数据总线：用于传输数据，是双向线。

地址总线：用于传输明确的地址信息，是单向线。

控制总线：用于传输CPU发出的控制信号，是双向线。

VISTA Bus interface module Steinstein

Part number :F404002A

Product name :VISTA bus connection module

Product status: Discontinued

Product packaging: original packaging

The VISTA F404002A bus connection module is a module for bus expansion that can be expanded into 2 loops.

The wiring mode of the VISTA F404002A bus connection module is: port is connected to the first pin from the left of J8, port 6 is connected to the seventh pin from the left of J8, and port 7 and 8 are connected to the power supply of port 7 and port 6 on the mainboard.

The bus system is generally composed of a transmission line + interface + bus controller, and its electrical characteristics are: the transmission direction and effective level range of the signal on each transmission line are divided into one-way bus (simplex), bidirectional bus (full duplex, half duplex). The most basic electrical characteristics are: at any time, there can only be one direction of information flow, no action is allowed. You can collect one, one more; We can't take more. We can take more. F404002A Master device connected to the bus. Only one master device is allowed to send data to the bus at any time.

Bus systems are divided into three categories according to the information they transmit:

Data bus: Used to transmit data, is a two-way line.

Address bus: Used to transmit clear address information, is a one-way line.

Control bus: used to transmit the control signal issued by the CPU, is a two-way line.
