Operator Messaging Address Enable Packet
The contents of this section apply to the FLEX Roaming Decoder. They are not applicable to
the FLEX Non-Roaming Decoder.
The operator messaging address enable packet is used to enable and disable the built-in FLEX
operator messaging addresses. Enabling and disabling operator messaging addresses does not
affect what frames the decoder IC decodes. To decode the proper frames, the host must modify the
FF bits in the Control Packet or the AF bits in the Frame Assignment Packets. The ID of the
operator messaging address enable packet is 4.
