4 LED’s

Tune:
Under optimum conditions, only the two outermost LED´s of the tuning indicator light
up. With PACTOR-II the frequency offset is additionally displayed (center display LED)
in red. In this case the middle of the tuning indicator is corresponding to the own
frequency and the LED in the middle represents the frequency of the distant station. If the
middle indicator drifts to the left, the frequency of the distant station is too low. If the
middle indicator drifts to the right, the frequency of the distant station is too high.
Besides the tuning-display it also serves to inditace several system conditions:
Autobaud:
After power-up the PTC-IIex tries to detect the baudrate of the terminal connected to. It
indicates this with a LED running from right to left and opposite.
Loading:
After a firmware update the firmware needs to be copied to the 32 bit wide SRAM
(loading). This condition is indicated with each second LED being on and off:
Update:
When the firmware or the BIOS are updated then the tuning-display shows an illuminated
dot running from left to right.
