FX16 Master Controller Technical Bulletin 113
Performing a Programming Key Memory Erase
If the key is already loaded with an application and you need to
substitute it with a different application, you can perform a memory
erase.
FX Loader automatically performs the memory erase when the
application is loaded from a computer. When the application is
uploaded from another FX16, you need to manually perform the
memory erase.
To perform a Programming Key memory erase:
1. Turn on the key, either by hot-plugging it to an FX16 (already on)
or with an AC/DC adapter.
2. Initiate the memory erase by pressing the key button down for
15 seconds.
During the erase, the green Light-Emitting Diode (LED) slowly
blinks. Then the green and the yellow LEDs blink twice alternately.
Finally the green LED remains steady on. The flash memory erases.
If the two LEDs blink simultaneously, it means that the erase process
has failed. Retry. When the memory completely erases, the LEDs stop
blinking. The key is now ready for a new upload. The memory erase is
also necessary if the previous upload from the FX16 did not finish
successfully (for example, if the communication failed or was
interrupted).
