NOTE: Codan’s KMS may be used to generate secure keys and to fill the CES
and AES encryptors.
NOTE: VCOM is used to provide virtual COM ports for programming secure
keys via KMS/KFS over the USB connector on the control point.
Secure keys may also be entered via the user interface of the control point, if
permitted. You can also replace a secure key with a new string of characters. You
cannot read existing secure keys.
CAUTION: If you edit a key, you must make the same change to the same key in
all other transceivers that want to communicate securely with this
station.
