Detailed Descriptions of Commands
REC PRESET (DAH+99H)
Sets the requirements for the Recording modes. Parameter bytes to follow to specify the requirements are the same format of those of the return data for REC PRESET SENSE (DAH+C9H).
The time mode and recording cycle cannot be set in combination. If both are specified, the time mode setting has priority, and the recording cycle setting is ignored.

First byte
Bits 2 to 0: Specify the Recording mode number.
Second and third bytes
Specify the tape length in units of minutes in BCD.
Fourth and fifth bytes
Each bit specifies whether to record the corresponding camera input.
0:Not to record
1:Record
Sixth byte
Specifies the image quality mode.
001:SUPER
010:HIGH
011:MID
100:LOW
111:No change
Seventh and eighth bytes
Specify the time mode in units of hours in BCD. When the time mode is not to be specified, pad both bytes with FFH.
Ninth and tenth bytes
Specify the recording cycle in units of 0.01 second by a BCD code.
When the cycle is not to be specified, pad both bytes with FFH.
ALARM PRESET (0AH+9AH)
Specifies the requirements for alarm recording.
The parameters to be set depend on the mode of alarm recording.
