Universal interface unit
First Claim
1. A universal interface unit for receiving input signals and generating corresponding output signals in one of a number of different formats in dependence upon the requirements of an external device to which the output signals are to be applied, comprising:
- means for generating a data signal relating to the signal format requirements of an external device;
a memory unit containing information relating to a plurality of different formats of output signals to be generated and, in response to said data signal, producing output information pertaining to the particular signal format requirements of the external device; and
processing means for receiving the input signals and generating the corresponding output signals in the format indicated by the output information from said memory unit.

Abstract
A universal interface unit for providing output signals in any one of a plurality of different signal formats stores information relating to each of the different available formats. When signals are to be provided to a particular device, personality data regarding the device enables the particular signal format requirements of the device to be read from the stored information. A signal processor responsive to this information generates output signals in that format. The output signals are transmitted to the device through a switching circuit that is appropriately connected to the device to provide the proper polarity.

8. A synchronizer for controlling the operation of any one of a number of different types of tape recorders having different control signal format requirements, comprising:
-
means for generating output signals indicating operations to be performed by the recorder; means for generating a personality signal that identifies the control signal format requirements of the recorder; a memory unit containing information relating to a plurality of different control signal formats and responsive to said personality signal to produce a format signal relating to the control signal format required by the recorder; a signal processor for receiving said output signals and generating corresponding switching signals having a format determined by said format signal; a switching device having two terminals that are selectively connected to one another in response to said switching signals; means for biasing one of said terminals to a predetermined potential; and means for connecting one of said terminals to the recorder. - View Dependent Claims (9, 10, 11, 12, 13)
