    • A transmission cable having a nonhalogenated jacket and a nonhalogenated composition for use as a transmission cable jacket. The jacket is prepared from a nonhalogenated polyolefin based formulation having flame retardant, low corrosivity, low toxicity and low smoke characteristics. The jacket material insulates a core transmission medium such as a metallic conductor or optical fiber. The jacket is extruded about the core or insulator during manufacture. The inventive cable has a jacket formed of nonhalogenated polyethylene and nonhalogenated ethylene vinyl acetate and provides a combination of desired mechanical characteristics, improved performance and manufacturing features while eliminating undesirable corrosive products released during a fire.

    • An infrared RS 232 communication link protocol is particularly suited for correcting any errors introduced during a transmission of information. The information is transmitted from a transmitting station to a receiving station. Each of the stations has a control counter each of which toggles between a logic 0 and 1. The control counter for the transmitter and the receiver are phase locked so that all errors may be corrected. The receiver echoes each data bit back to the transmitter which compares the echoed data to the transmitted data. If there is a match, the transmission was successful. If there is no match, the data must be retransmitted. A retransmit control character RTXx is sent to indicate that the receiver should discard the previous character and prepare for a retransmission of the character having the error. Under the proper circumstances and if the counters are still phase locked, the receiver then discards the previously stored character and inverts the counter. If the receiver detects that it has received an erroneous character, such as one having multiple or no PPM pulses, the receiver will simply respond with the reject control character REJ. In such a case, the transmitter will respond with an RTXx which causes the receiver to discard the previously stored character and invert the counter.
    • 红外RS 232通信链路协议特别适用于校正在信息传输期间引入的任何错误。 信息从发送站发送到接收站。 每个站具有控制计数器,每个控制计数器在逻辑0和1之间切换。发射器和接收器的控制计数器被锁相,从而可以校正所有错误。 接收机将每个数据位回送到发送器,发送器将回波数据与发送的数据进行比较。 如果有匹配,则传输成功。 如果没有匹配,则必须重发数据。 发送重发控制字符RTXx以指示接收者应丢弃先前的字符并准备重发具有该错误的字符。 在适当的情况下,如果计数器仍然锁定,则接收器将丢弃先前存储的字符并反转计数器。 如果接收机检测到它已经接收到诸如具有多个或没有PPM脉冲的错误字符,则接收机将简单地用拒绝控制字符REJ进行响应。 在这种情况下,发射机将以RTXx进行响应,导致接收机丢弃先前存储的字符并反转计数器。
