Abstract: A multichannel communications recorder having the capability to display channel activity, failsafe back-up capability, a unique identification code with provision for changing such code, and apparatus for securing access to the communications recorder. The recorder is formed from modular elements. In each configuration one or more record decks is controlled by a control module having a display. Control is provided by a user selecting to implement functions defined in accordance with a particular page displayed. Acces to various pages is controlled by various levels of passwords with the highest level being used by a service person to input information defining selected configuration and to run diagnostic tests and lower levels being provided to users of the system. Because of the need to provide physical security for recorded tapes, each tape deck is secured by an electro-mechanical lock, which operates under system control.

Abstract: A multichannel communications recorder with capability to display channel activity, failsafe back-up, and a unique identification code; and apparatus for securing access to the recorder. The recorder is formed from modular elements configurable into a large number of selectable configurations. One or more record decks are controlled by a control module which includes a system control microprocessor and a CRT control microprocessor. Control is provided by selecting functions defined in accordance with a displayed page or moving to another page using softkeys. Access to various pages is controlled by various passwords. Because of the need to provide physical security for recorded tapes, each tape deck is secured by an electro-mechanical lock, which operates under system control. The system is provided with the capability to be configured in configuration providing back-up for selected channels.

Abstract: A multichannel communications recorder or logger having the capability to display channel activity, failsafe back-up capability, a unique identification code with provision for changing such code, and apparatus for securing access to the communications recorder. The recorder is formed from modular elements which may be configured into a large number of selectable configurations. Possible configurations include provision of back-up record decks and back-up record amplifiers, as well as various selectable auxiliary components. In each configuration one or more record decks is controlled by a control module which includes a system control microprocessor and a CRT control microprocessor, which, in turn, controls a user interface including a CRT for displaying pages of control information and a plurality of softkeys.

Abstract: An apparatus and method for scanning a moveable record medium, detecting the presence of signal information on the moveable record medium and halting the moveable record medium at the detected signal information or automatically rerecording the detected signal information. The method and apparatus is particularly adapted to function in a multichannel logging system, wherein the desired signal information is intermixed with low frequency time and information signals. The method and apparatus is capable of filtering out the low frequency signals while the tape moves at speeds between playing speed and up to 100 times playing speed, detecting if any signal information remains, and either halting the tape at the detected signal information or automatically rerecording it.
