A communication system includes: a transmitter configured to be responsive to a control request from a local device that facilitates toggling of the transmitter On and Off in a pattern of interruption to generate multiple consecutive On/Off bits having On/Off signals with a same pulse width that represents control information, the transmitter configured to transmit data via a communication medium at a first end thereof, the communication medium also having a second end; and, in response to the pattern of interruption, the transmitter is configured to interrupt the communication medium at the first end, each interrupting of the communication medium at the first end resulting in a detection of a loss of signal at the second end.

Method, apparatus and system for changing to which remote device a local device is in communication via a communication medium through use of interruption of the communication medium

A method, apparatus and system for changing to which remote device a local device is in communication via a communication medium, communicates with a matrix switch forming part of the system by interruption of the communication medium by the local device. Upon receipt of a unit of information via interruption of the communication medium, the matrix switch causes the local device to be in communication with another remote device other than the remote device that it was previously in communication. In one embodiment, the switching is to a next available remote device of a plurality of remote devices while in another embodiment, the matrix switch switches the local device to a switch configuration device for further communication therewith via the communication medium, thereby allowing the local device to select which other remote device it desires to be in communication.

A video data extension system includes a transmitter and a receiver for transmitting and receiving encoded serial data. Transmitter is configured to receive one SDI 3G video stream at 2.97 Gb/s, two HD-SDI video streams at 1.485 Gb/s, two SD-SDI at 270 Mb/s, or one HD-SDI at 1.485 Gb/s and one SD-SDI at 270 Mb/s. Received data is segmented into packets to form an extended video stream for transmission at 3.75 Gb/s. To each packet, idle and header are provided. Data such as RS422 data may be included in the extended video stream. Where the received data includes data from two HD streams, received data are segmented into two groups of data packets for arranging into extended video stream in an alternate manner. Upon receiving the extended video stream, receiver uses idles to align data and header information to separate the HD streams.

Wiring tester plug

A master control unit of a cable tester in accordance with the present invention comprises a housing having an upper portion and a lower portion. The master control unit includes a display, a pivotal cover, an indicator, a modular jack, and an activation/selection button. Electronics of the cable tester are disposed with the housing. A remote unit compatible with standard modular jacks comprises a housing for supporting a printed circuit board and a cover. The housing comprises an elongated generally rectangular portion which is sized so as to be compatible with standard modular jacks. During use the master control unit is connected by a jumper cable to a modular jack under test. The modular jack under test is connected by wiring to another modular jack, also under test, at another location. The remote unit is inserted into and mates with the other modular jack. Testing is performed at master control unit. The master control unit includes display indications for low battery and for the presence of line voltage at the display. The switch is used to index through the test modes. The indicator lights each time the button is pushed, with each screen change, during testing, and remains lit to indicate a pass condition.

Cable tester

A shielded connector assembly having a snap locking mounting scheme. The assembly includes a panel yoke (2) with snap locking elements (21) for snap lockingly, removably securing the panel yoke (2) in a panel or cover plate. The panel yoke (2) is also constructed to snap lockingly engage a shielding device (30) which in turn is constructed to snap lockingly engage a connector assembly comprising an interconnecting device (61) which may be a printed circuit board (59) including integrally defined reactive elements designed to compensate for reactive imbalance of electrical components connected thereto. A pair of wire termination blocks (70) mounted to a first side of the circuit board are connected by circuitry on the circuit board to a corresponding modular jack (60) mounted on a second side of the circuit board. The reactive elements produce an impedance between selected leads of the modular jack and the wire termination blocks by the circuitry. A snap locking combination of the shield device (30) and a shielding cover (90) completely shields the connector assembly (61). For joining the assembly parts, the shield includes pawls (32) and engagement members (33) that latch to cutouts (18) in the yoke and to apertures (94) in the shield cover, respectively. The shield device (30) includes a cable shield restraint (36). In one embodiment, a dual opening yoke receives two shielding devices. In another embodiment, a single opening yoke receives one shielding device.
