General Description
The Black Box Data Recorder (model: MUX-8A) is an 8-channel data recorder packaged in a 4.1" by
2.6" by 1.7" black box which is tie wrapped under the instrument panel. Also, there is a Control Switch,
Record Light and RS-232 Port that may be mounted on the aircraft instrument panel. Channels 1 through 7
on the Data Recorder are designed to receive the RS-232 (5V) output signals from any Electronics Interna-
tional Instrument equipped with the RS-232 (5V) option. E.I.'s Ultimate Bar Graph Engine Analyzer (model
UBG-16) comes with a RS-232 output. Other E.I. Instruments must to be ordered with the RS-232 option
to be able to operate with the Data Recorder. Channel 8 on the Data Recorder is designed to receive RS-
232 moving map data from a GPS instrument (most GPS instruments output moving map data).
Any channel on the Data Recorder can be enabled or disabled with the DIP switchs found in an open-
ing on the side of the Data Recorder's black box. The Data Recorder scans the enabled input channels,
formats the incoming data and stores the data to internal memory. Also, as the data is stored in memory it is
transmitted to the RS-232 Port. This allows data to be transmitted directly to a P.C. using Electronics
International's Professional Data Recording Software (DRS-18).

If the Control Switch is placed in the "ON" position, the Data Recorder will
store data to internal memory according to the Storage Time Interval setting (1, 3, or
6 minutes) set by the DIP switches found in an opening on the side of the Data
Recorder's black box.
If the Control Switch is place in the "BURST" mode, the Data Recorder will
store data as fast as it can. The Storage Rate is determined by totaling the Transmit
Rates of the instruments to which its connected. The Transmit Rate for various E.I. Instruments are shown
below:
