The Select Desired IRIG Code Menu allows the user to select the desired IRIG Serial Time Code to
be translated by the Translator.
Pressing the PREV switch while this menu is shown on the LCD Display will return it
to the Set-Up Translator Menu, Figure 3.
A blinking cursor appears at the presently selected IRIG code to be translated. If the desired code
has been selected, pressing the NEXT switch will cause the Translating Menu, Figure 8 to be
displayed on the LCD Display.
If there is not a blinking cursor on this menu no IRIG code has been selected. If it is desired to see

appear on the LCD Display showing the selected Translator code selected in the upper right hand
corner after “Translating”.
If the input code is different from that shown on the display, it is necessary to select the correct
code. Changing the code selection is accomplished by pressing the switch beneath the desired code.
When the new desired code is selected, the LCD Display will change to that shown in Figure 8 with
the selected code being translated shown in the upper right hand corner of the display.
The selection of SP1 or SP2 are reserved for translation of special codes, and the message “Selected
option is not installed…(See Figure 11) will appear. If either one of these special codes are
provided, its option description will be inserted at the end of this Appendix.
