摘要： A remote staton is disclosed for use in a supervisory system capable of effecting both monitoring and controlling functions. The station includes transmitter and receiver sequencers for both transmitting and receiving coded instructions and responses. Each received message is decoded by the receiver sequencer and the correct field point addressed, while the message is verified, and a response encoded and transmitted.

摘要： A method and apparatus for decoding biphase signals are disclosed in which each bit of a received biphase signal causes generation of a window in which the next successive bit must fall. By this means the received message is distinguished from noise and timed. The received signal message preferably includes a synchronization code and a double word body formed by a single word which is transmitted twice. The synchronization code is examined for both timing and pattern. The second word is compared bit by bit with the first word to verify the received message and further preclude the possibility of noise being erroneously considered as a message bit. If the two words are not identical this indicates an error and all further action is inhibited.
摘要翻译：公开了一种用于对双相信号进行解码的方法和装置，其中所接收的双相信号的每个位引起产生下一个连续位必须下降的窗口。通过这种方式，接收到的消息与噪声和定时不同。接收到的信号消息优选地包括同步码和由单个字形成的双字体，其被发送两次。对时序和模式进行同步码的检查。将第二个字与第一个字逐个比较，以验证接收到的消息，并进一步排除噪声被错误地视为消息位的可能性。如果两个字不相同，则表示错误，并且所有进一步的操作被禁止。

摘要： A transmitter sequencer is disclosed having an encoder section and a transmission line driving section. The encoder serves to generate a biphase output code from an input level and to pass the coded message to the line driver. The line driver is normally inhibited to prevent undue loading of the transmission line, but is enabled when a message in biphase code is to be transmitted.

摘要： An analog to digital converter is disclosed having control and comparator portions. The control portion is formed by a number of J-K flip flops arranged to sequentially receive on their J inputs the decoded output of a binary counter. The flip flops in turn control by their Q outputs a number of analog switches in the comparator portion. The switches are connected to feed a reference voltage to a ladder network and obtain a voltage for comparison with a multiplexed analog voltage in a comparator. The output of the comparator controls the setting and resetting of the flip flops with their final set giving the binary analog to digital output.
