Each Filler field contains 7 hexadecimal characters representing the 2 type bits and 26 information bits of the control filler/message word. The dotting, word sync, and parity bits are generated automatically.

Operating Considerations

The control filler is sent continuously when Send Filler is selected, or after a control message has been sent using Send. The control message is stopped whenever Stop Filler, Filler, Channel, Data Rate, Polarity, or AFGen2 To is selected.

Both filler fields must be full (seven digits) for the forward control channel information to be structured correctly. Do not leave any blank spaces.
