The control unit has been developed to provide full STANAG 5017 facilitates for the ESD446 microminiature transponder. Capable of operating simultaneously on modes 1, 2, 3/A and C, the unit incorporates special features for reply code selection. Code entry for modes 1 and 3/A is manually effected by use of the keypad, thus eliminating difficult to operate thumb-wheel switches. Pressing the •#’ key enables the keypad for 10 seconds during which period the four digit code may be entered. The loaded code is displayed in the pending windows and may be transferred to the active window and stored by the operation of a single toggle switch.
