IS230TBAIH2C控制燃机卡件，GE使用在哪里

EIA-232-D标准定义了该系统的电气和机械方面串行接口。该接口采用不平衡（单端）信令通常与DB25连接器一起使用，尽管其他连接器样式有时也会使用（例如DB9和RJ45）。表A-1列出了标准EIA-232-D互连。中未列出所有管脚该表在每个应用中都是必要的。要正确解释信息，请记住EIA-232-D串行开发了将终端连接到调制解调器的接口。串行数据页发送设备位于传输数据（TxD）线上，并到达接收端接收数据（RxD）线上的设备。

IS230TBAIH2C控制燃机卡件当计算设备在没有调制解调器的情况下互连，其中一个单元必须配置为终端（数据终端设备：DTE），另一个作为调制解调器（数据电路终端设备：DCE）。因为计算机通常配置为与终端一起工作，它们被称为配置为调制解调器在大多数情况下。1.EIA-232-D高信号电平为+3至+15伏。低水平是-3至-15伏。并联连接装置可能会产生超出范围的电压，这违反了规范。2.EIA-232-D接口旨在将终端连接到调制解调器当连接计算机时没有调制解调器，一台计算机必须配置为调制解调器，另一台计算机必须配置为调制解调器作为终端。接口特性EIA-232-D接口标准规定了串行二进制文件的所有参数使用不平衡线路在DTE和DCE设备之间进行数据交换。适用于MVME162的EIA232-D发射器和接收器参数为在表A-2和A-3中列出。MVME162符合EIA-232-D规范。注意，虽然EIA-232-D标准建议使用短互连电缆如果电缆长度超过50英尺（15m），则允许使用更长的电缆在接口点测量的总负载电容，包括信号终止器不超过2500pF。EIA-530连接EIA-530接口在功能上补充了EIA-232-D接口。这个EIA-530标准定义了该接口的机械方面，即用于传输串行二进制数据，包括同步和异步。它适用于平衡（双端）和不平衡（单端）信令，并提供更高数据的可能性使用相同的DB25连接器时，速率高于EIA-232-D。表A-4列出了串行端口B上可用的EIA-530互连（前面板上的串行端口2），当通过串行端口配置端口时作为EIA-530 DCE或DTE端口的接口模块。

The EIA-232-D standard defines the electrical and mechanical aspects of this

serial interface. The interface employs unbalanced (single-ended) signaling

and is generally used with DB25 connectors, although other connector styles

(e.g., DB9 and RJ45) are sometimes used as well.

Table A-1 lists the standard EIA-232-D interconnections. Not all pins listed in

the table are necessary in every application.

To interpret the information correctly, remember that the EIA-232-D serial

interface was developed to connect a terminal to a modem. Serial data leaves

the sending device on a Transmit Data (TxD) line and arrives at the receiving

device on a Receive Data (RxD) line. When computing equipment is

interconnected without modems, one of the units must be configured as a

terminal (data terminal equipment: DTE) and the other as a modem (data

circuit-terminating equipment: DCE). Since computers are normally

configured to work with terminals, they are said to be configured as a modem

in most cases.1. A high EIA-232-D signal level is +3 to +15 volts. A low level is

-3 to -15 volts. Connecting units in parallel may produce outof-range voltages and is contrary to specifications.

2. The EIA-232-D interface is intended to connect a terminal to a

modem. When computers are connected without modems,

one computer must be configured as a modem and the other

as a terminal.

Interface Characteristics

The EIA-232-D interface standard specifies all parameters for serial binary

data interchange between DTE and DCE devices using unbalanced lines. EIA232-D transmitter and receiver parameters applicable to the MVME162 are

listed in Tables A-2 and A-3.The MVME162 conforms to EIA-232-D specifications. Note that although the

EIA-232-D standard recommends the use of short interconnection cables not

more than 50 feet (15m) in length, longer cables are permissible provided the

total load capacitance measured at the interface point and including signal

terminator does not exceed 2500pF.

EIA-530 Connections

The EIA-530 interface complements the EIA-232-D interface in function. The

EIA-530 standard defines the mechanical aspects of this interface, which is

used for transmission of serial binary data, both synchronous and

asynchronous. It is adaptable to balanced (double-ended) as well as

unbalanced (single-ended) signaling and offers the possibility of higher data

rates than EIA-232-D with the same DB25 connector.

Table A-4 lists the EIA-530 interconnections that are available at serial port B

(SERIAL PORT 2 on the front panel) when the port is configured via serial

interface modules as an EIA-530 DCE or DTE port.
