Converting from ISO to conversational format and back

Question:

Is it still possible to switch from DIN/ISO programming to conversational programming on the new controls?

Answer:

This function was only possible up to the TNC 355.

On the successor controls TNC 4xx, iTNC 530, TNC6xx, TNC 320 and TNC 128 you can store DIN/ISO as well as conversational (plain-language) programs on the control at the same time (with .I as the file extension for DIN/ISO, and .H for conversational), without having to reboot the control each time.

Furthermore, you can call a conversational program from a DIN/ISO program just as well as a DIN/ISO program from a conversational program.
