Numerical Command - Sony HVO-500MD Protocol Manual

Numerical Command

This command is used to specify numerical parameters. It is used also to return a numerical data such as
time data and CTL from this device. There are 3 formats available (byte-parameter input, multi-byte
parameter input, multi-type parameter input) as shown below.
Byte-parameter input
This is used to specify a 1-byte numerical parameter. NAK will be returned if a non-numerical command is
entered.
FWD SHUTTLE and REV SHUTTLE commands belong to this type.
Ex) Double speed playback

Command

"ACK"
Multi-byte parameter input
This is used to specify a multi-byte numerical parameter. Such a numerical parameter is composed of a
plurality of bytes including a sign code, and is always ended by ENTER (40H).
Each command has a fixed maximum number of bytes, and when this value is exceeded, the numerical part
that comes behind is valid. However, the sign command is given a special treatment.
CTL PRESET and SEARCH commands belong to this type.
Ex) An example of setting the preset value of CTL to "0:12:34:12"
