3-14. C3ECC ERROR CORRECTION (Applies to DDS Tape Drives Only).
C3ECC
error correction can be enabled or disabled by this configuration option. By default, it is
left disabled, because enabling it can significantly reduce the capacity of the media. There is
typically no need for this additional level of error correction on audio because, unlike data, there
is an enormous amount of redundancy built into speech, and if an error were to occur, it would
likely not be noticeable. We recommend that it be left disabled.

3-15. RELAY.
Relay
configures operation of the relay contacts connected to the front (mini-plug) and rear
panel (1/4” phone jack). One contact of the relay is connected to ground (the connector sleeve).
The other is connected to the tip on the front jack, the ring on the rear jack. The relay is
“normally closed”, so that if no power is applied to the unit, there is continuity across the
contacts. In this way, the relay unconditionally closes when the unit loses power and can
provide a remote indication of this condition. The relay can also be programmed to
Close
under
certain circumstances. When you hit the
Relay
soft key, the legend
RELAY CLOSES ON:
appears on the top line of the display and three soft keys appear on the bottom.
