NOTE: VCOM is used to provide virtual COM ports for
programming secure keys via KMS/KFS over the
USB connector on the control point.
NOTE: Only one application connected via VCOM may be
serviced by the RFU at a time. Refer to Using VCOM
services on page 126 for further details on this
limitation.

Convoy Web Portal or via a USB stick. Refer to

encryptor via the user interface of the control point, the transceiver

secure key.

point, KMS/KFS, Codan Convoy or USB sticks.
