CUL FAQ
1. My CUL was initialized with X21 to receive data but there is no
output. I am sure that there is traffic on air. CUL responds as expected to
other commands like V. Is my CUL defect?
Please check the response to command C35
. Reception mode is
turned on if the return value is 13
. If reception mode is
enabled but nothing is received, the EEPROM data is probably corrupt. You
can reinitialize the EEPROM data with the default setting from program code
with the command e (which will result in a reboot of the CUL).
