The RADSCOM package is a menu driven program containing functions that enable communications between
the CADU and an IBM or IBM compatible computer. These functions allow the user to initialize the CADU RAM
disk, create the CADU file structure, transfer data from the CADU to the PC, transfer data from the PC to the
CADU, and create the Credit Card file structure.
The following notations are used in this section:
file name: name of a file residing on the PC
path to the file to be referenced on the disk (e.g. C:\RADSCOM\AC_Types
Listed below are the most commonly used RADSCOM single-letter selections and a short description of each.
They are sorted according to the RADSCOM menu in which they appear. Some commands appear more than
once in the program and will therefore appear more than once in the description:
Main Menu (see figure 1)
Allows CADU backup data to be transferred to the PC when using Backup to PC option on the CADU.
Load a data or aircraft setup file into the CADU from the IBM (or compatible) PC.

Loading Aircraft Script Files to CADU
The following is the procedure for installing the individual aircraft script files for AVA system operations:
It is not required to install all aircraft script files from the
PC to the CADU. It is recommended that only the
required aircraft files needed by the user be installed.
a. Connect CADU RS232 port (9-pin connector) to PC RS232 port.
b. Reboot CADU as described in Section 8 of this procedure..
c. When the boot menu appears on the CADU, select Option 2, set up for host communications.
