A data gathering and transmitting system includes a portable data gathering device having a keyboard and an input/output connector, each operable for entering data into, and for providing access to data previously entered into, a random access memory. Data as entered is displayed simultaneously; data in memory may be selectively accessed for display by addressed locations and in various automatic scan modes. The portable device thus operates as a true electronic notebook. An interface-formatter located at a remote terminal communicates with a computer, and provides for read-out of data from the portable data gathering device and automatic conversion and formatting of the data to a form suitable for direct transmission to the computer, and for print-out of a hard copy of the data. Where a hard copy print-out is not required, a read-out unit may simply transmit the data without formatting to a distant central receiver suitably programmed to receive and interpret the data transmission. Data may also be transmitted from a computer or distant central transmitter to the interface-formatter for entering data into the memory of the electronic notebook via the input-output connector. Thus, data can be loaded into the electronic notebook from a remote computer, the data can be displayed for reference, and field changes and additions can be made to the data. The massaged data can then be transmitted back to the computer.
