Output loops all adopt the photoelectric isolation , its anti - interference ability is strong . and it can also carry serial communication interfaces 可带串行通讯接口，可与各种带串行接口的设备进行双向通信，组成网络控制系统。
Pipes are bi - directional . os 2 returns a single handle when a pipe is created , and this handle is used for bi - directional communication between processes 在os / 2中，管道是双向的，当创建管道时会返回一个句柄，这个句柄可以用来在进程间实现双向通信。
Semiconductor planar flight emitting device make it high brightness , softened color , low power consumption , parallel driven , long lifespan and convenient replacement of screens 可带串行通讯接口，可与各种带串行接口的设备进行双向通信，组成网络控制系统。
Application settings uses the windows forms data binding architecture to provide two - way communication of settings updates between the settings object and components 设置绑定应用程序设置使用windows窗体数据绑定结构，提供设置对象和组件间设置更新的双向通信。
But , the prospect of rebuilding existing cable plants for high - speed bidirectional communications and extending cable until it matches the reach of copper is a difficult challenge 但是，把现有的电缆线路设备改建成适合高速双向通信延伸电缆直至与电话铜线相匹配是一个困难的挑战。
If the event notification targets a service on a remote server , both the source server and the target server must have routes defined on them to make sure that two - way communication occurs 如果事件通知指向远程服务器中的服务，则源服务器和目标服务器必须都定义了路由，确保实现双向通信。
Between the center and the devices , the duplex communication links are created through the public switched telephone network , thus the remote management for the devices is realized 集中管理中心与集中管理式电话计费器之间可通过公众电话网以拨号方式建立双向通信链路，从而实现对集中管理式电话计费器的远程管理。
With a server - driven system the only way to achieve this level of control is to have regular two - way communication between the providers and the work unit broker and for each provider to process one work unit at a time 对于服务器驱动的系统，惟一实现这一级别控制的方法是使提供者和工作单元代理之间有定期的双向通信，并让每一个提供者每一次处理一个工作单元。
As to the bipolar communication , we not only afford a serial communication port , but also design an integrated scheme for communication network . it provides a necessary condition for packing machine to achieve the goal of computer integral guide 在吸塑机的双向通信功能上，我们不仅仅停留在提供通信接口，而是从目前包装机械的发展趋势着眼，提供了一整套开放式的包装机械连网方案，为日后机群控制功能的实现提供了必要条件。
Furthermore , by using the normal serial interface rs - 232c , we make the intelligence releaser realize communication with pc computer . by using the bus system , the target of remote controlling is realized . all of them strengthen the releaser ' s functions and make it accord with requirements of distribution system 此外，采用目前最常用的串行通信标准总线接口rs - 232c ，实现了现场智能脱扣器与pc机的双向通信功能，通过总线系统达到遥调、遥控的目的，使得脱扣器的性能得到提高，功能得到增强，符合配电系统的要求。
