2.5 Standby Off – 0x20 0x04
This has no effect on the device. It will respond with ACK to maintain
compatibility with typical controllers.
2.6 Standby On – 0x20 0x05
This has no effect on the device. It will respond with ACK to maintain
compatibility with typical controllers.
2.7 Deterministic Play Arm – 0x20 0x08
This arms the deterministic (i.e. frame accurate) playback start. Please see the
Deterministic Playback chapter later in this document for details on this feature.
This command responds with ACK.
2.8 Deterministic Play Disarm – 0x20 0x09
This disarms a previously armed deterministic play command. Please see the
deterministic play section later in this document for details on this feature. This
command responds with ACK.
2.9 Eject – 0x20 0x0F
This command has no effect on the device. It will respond with ACK to maintain
compatibility with typical controllers.
2. 1 0 Fast Forward – 0x20 0x10
This command puts the device in fast forward playback. This is roughly 20x real
time speed. This command responds with ACK, but will do so before the transport
state has changed. Use the status bits to determine when the device has actually
changed state.
Speed Data Payload Description
When one of the commands listed below is received, the DEVICE starts running in
accordance with speed data defined by DATA-1 and DATA-2.
• Var Forward – 0x2X 0x12
• Shuttle Forward – 0x2X 0x13
• Jog Reverse – 0x2X 0x21
• Variable Reverse – 0x2X 0x22
• Shuttle Reverse – 0x2X 0x23
When only DATA-1 is given, (X = 1) and the tape speed will be defined as follows.
TAPE SPEED = 10
TAPE SPEED
STILL
0.1 times normal speed
1.0 times normal speed
About 2.9 times normal speed
TAPE SPEED = 10
N = SPEED DATA OF DATA-1 (DECIMAL), N' = SPEED DATA OF DATA-2 (DECIMAL)
