Interface circuitry was designed so that telemetered data originating from various remote stations could be recorded by both a digital computer and an analog recorder. The entire interface circuitry is mounted on a 3-1/2 x 2-1/2 inch printed circuit card and installed in the receiver. Data from the two methods of collection can, therefore, be collected and a comparison can be made. A switching network also permits computer control with computer and recorder logging; or computer logging only; or recorder logging only.
