开关主机和插卡是否兼容系统中的其它设备，以实现触发、控制及连接？
Are the switch mainframe and CARDS compatible with other equipment in the system with respect to triggering, controls, and connections?
为了将开关卡的输出连接在一起，特定开关卡的输出都会被连接到扫描仪主机的背板。
To connect the outputs of the cards together, certain cards have their outputs connected to the backplane of the scanner mainframe.
在收集完这些信息后，就能够很容易地确定所需开关主机及开关卡的类型和数量。
Once this information has been gathered, determining the type and number of switch mainframes and CARDS required is straightforward.
依据程序清单进行编程，写入PLC主机。调整PLC主板后面的地址开关，再软起动，机床恢复正常。
Programming according to the list, write PLC host. Adjust the address switch on the back of the PLC board, and then soft start, the machine is back to normal.
大多数开关主机都可通过触发输入进行外部触发，并且在继电器触点稳定之后可输出一个触发脉冲。
Most switch mainframes can be triggered externally via the trigger input and can send an output trigger pulse when the relay contacts have settled.
扫描仪主机的背板可连接每个开的相应开关组。
The backplane of the scanner mainframe will connect the appropriate Banks of each card.
如果将没有背板连接的特殊开关卡安装到主机的某个插槽，那么它和主机中安装的其它插卡则是电气隔离的。
If a particular switch card with no backplane connection is installed in a slot of the mainframe, it will be electrically isolated from other CARDS installed in the mainframe.
这样就可以将主机内某个开关卡的输出连接到其它开关卡。
This allows the outputs from one card to be connected to the other CARDS in the mainframe.
在开关主机中精心配置开关卡，以及在设备机柜中精心配置开关系统，都可以减小这种影响。
Such effects can be reduced by thoughtful placement of a switch card within a switch mainframe and of a switch system within an equipment rack.
第3章着重介绍了开关卡和主机。
Section 3 addresses switch card and mainframe considerations.
第3章详细介绍开关卡和主机的技术指标。
Section 3 provides a detailed description of switch card and mainframe specifications.
该值可和开关主机的驱动电流容量一起来确定主机内同时可闭合多少继电器。
This value can be used with the drive current capacity specification for a switch mainframe to determine how many relays the mainframe can close at one time.
将开关卡安装到主机上，并使仪器预热。
Install the switch card into the mainframe and allow the instruments to warm up.
请确保导线足够长，能够方便地从主机中拆下开关卡。
Make sure the wires are long enough so that the switch CARDS can be removed easily from the mainframe for service.
当源表和开关主机通过TriggerLink连接时，它们能够彼此触发，可更快地进行测试。
When the SourceMeter instruments and switch mainframe are connected via trigger Link, they can trigger each other to allow faster test execution.
主机也被称为扫描仪、复用器、矩阵或可编程开关。
A mainframe is also referred to as a Scanner, Multiplexer, Matrix, or Programmable Switch.
在707a型开关主机中，可按这种方式连接多达6块矩阵卡。
Up to six Model 7174a matrix CARDS can be connected in this manner in a Model 707a Switching Mainframe.
主机总电源开关不能启动：检查主令继电器是否损坏，过流继电器是否跳闸。
Total mainframe power switch could not be activated: check whether the Master relay is damaged, whether the flow relay tripped.
根据测试流程，给出了主机控制程序设计及部分实现代码，并针对开关矩阵硬件构成，分别给出了各个组成部分的固件程序代码。
According to test flow, the host program and its partial code are given, and according to the hardware structure of switch matrix, the firmware of each part is also given.
开关包括获取模式，其中主机仅看见存储设备中的空闲空间而看不见存储了信息的部分。
The switch includes a get mode wherein the host sees only the free space in the storage device and not the part storing the information.
一种连接至主机的移动存储系统，该移动存储系统包括用于存储信息的存储设备和开关。
A portable storage system for connecting to a host, the portable storage system includes a storage device for storing information and a switch.
对于兼容Keithley 7001和7002型主机的开关卡，利用卡上的跳线可连接或断开背板连接。
For some switch CARDS compatible with Keithley's Models 7001 and 7002 mainframes, jumpers on the switch CARDS enable connection or disconnection from the back plane.
