Abstract
A multichannel communications recorder or logger. The recorder is formed from modular elements which may be configured into a large number of selectable configurations. 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. Control is provided by a user selecting to implement functions defined in accordance with a particular page displayed. Access to various pages is controlled by various levels of passwords with the highest level being used by a service person 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 provided with a door secured by an electro-mechanical lock. Because of the need to maintain continuous monitoring in many applications, the system is provided with the capability to be configured in configurations providing back-up for selected channels. Also, since each record deck is provided with a local controller in the event of a failure of communications with the system controller, a local controller may initiate transfer to a back-up record deck using a hardwired connection. The communications recorder of the subject invention also records a time code and a unique machine code identification number on each tape. The machine code may be changed through use of a unique one-time password obtained by a service person from the system manufacturer.
