Unity 4600 User's Manual
SAVEP [entry#] [channel_label]
entry#: A Preset Table Entry number or the text, "PERM". If a preset entry,
must be equal to number between 1 and N inclusive, where N is highest entry
number.
channel_label: Channel Label associated with a unit setting or a Preset Table
entry. If attempting to supply the channel_label parameter alone, a value of
"PERM" is not legal. Parameter must be a string of continuous non-white-
space keyboard characters. Unit will truncate user input to 10 characters.
Command saves current Unit Settings to a Preset Table entry, or if entry# is
"PERM", a current Transient Setting is loaded into the unit's Permanent unit
setting. Those metadata fields in the extended Preset Entry that have no analog
in the current Unit setting will be populated with spec defaults. User must use
ADDE to set those fields.
If entry# is supplied alone, current unit settings are written to that entry, over-
writing existing data if it had been in use. If channel_label is supplied alone,
and if that same Label already appears at a used Preset Table entry, then the
current unit settings overwrite that old Preset data. If channel_label is supplied
alone and no used Preset has that Label, then the current settings are written to
the lowest empty Preset Table entry and then given that same Label. If both
entry# and channel_label parameters are supplied, then the current unit set-
tings are written at that Entry (overwriting existing data if any) and that entry is
supplied that same Label (equal to channel_label).
SERVICE video_pid [pcr_pid] [audio1_pid] [audio2_pid]
video_pid: Hex value between 20 and 1ffe.
audio1_pid: Hex value between 20 and 1ffe.
audio2_pid: Hex value between 20 and 1ffe.
pcr_pid: Hex value between 20 and 1ffe.
Command selects A/V services directly by PID number only. This changes
Unit Setting #11 to "By PID" if not already set that way.
