Protocol Overview
The Serial Control Protocol consists of three command characters and parameter characters of variable length.
C ha racters are the ASCII Code.
RS 232C Protocol
Controller –> Device Message Example
Disc Tray (Open) Special Character
[CR] Carriage Return ASCII Code 0x0D
Device– > Controller Message Example
Status = Play
ETHERNET Protocol
Protocol is TCP. (Transmission Control Protocol)
Destination Port Number is 9030. fixed)
Controller –> Device Message Example
Disc Tray (Open)
Special Character
[CR] Carriage Return ASCII Code 0x0D
Device –> Controller Message Example
Status = Play
1 Unit Type is the model category ID. The Blu ray player is “7”.
Note: The connection between server and client should be held open continuously. If the connection is closed, the client will not be able to see Status notification messages from the server. Only one client connection at a time can be made.
Communication Protocol
Message Structure
There are three kinds of message, “COMMAND”, “REQUEST”, and “ANSWER /NOTIFICATION”.
ACK (Acknowledge) and NACK (Not
ACK
It is an affirmative reply sent to a controller from a device. When data transfer completes properly, a device notify of that to a controller.
NACK
It is a negative reply sent to a controller from a device. When data transfer does not complete properly, a device notify of that to a controller. Name| Value(HEX)| Transmission Requirement
---|---|---
ACK| ‘ack’ (0x61/0x63/0x6B)| The device acknowledged that the command was received normally from the controller.
NACK| ‘nack’ (0x6E/0x61/0x63/0x6B)|

    * The device received the End Character ‘CR(0x0D)’ before receiving the Start Character ‘!(0x21)’.
    * The device does not receive ID’7(0x37)’just after Start Character’!(0x21)’.
    * The device receives an unknown character just after ’!7’.
    * The device receives an unknown command just after ’!7’.
    * Parameter is out of range.
    * The size of data is abnormal.
    * 5msec passed before the device receives the next code necessary to complete the command.  
3.  **Communication Rules

**

  1. Initiative of Communication

In the communication between a controller and a device, the controller must have the initiative. However, the Status Information notification automatically from the device is an exception.
When the device receives a command from the host, the device returns the following.

    * When receiving the command which doesn’t require a status information ACK (‘ack’)
    * When receiving the command which require a status information

ACK (‘ack’)＋(‘+’) Status information (ANSWER)

    * For the communication failure or an unknown commands etc. NACK (‘nack’)
  2.  **Communication Sequence

** The host must not send any new command after the previous command before the host receives ACK or NACK, or the timeout (see ”4.3.3. Timeout”) has expired.

  3.  **Timeout**

After a controller sends a message to a device, the host waits for a reply from the device for 30 ms (IP Control) / 300 ms (RS-232C). When the controller does not receive a reply over 30 ms (IP Control) / 300ms (RS-232C) from the device, the controller sends the same message to the device. However, when the controller does not receive a reply from the device after sending the same message 3 times (that means Tim Out), the controller sends End character ‘CR’ (0x0D) to the device. After that, the controller should execute the recovery process such as retry. TASCAM-BD-MP4K-
Control-I-O-Terminals-8

  4.  **ACK**

Refer to “4.2.1. ACK”.

  5.  **NACK**

The device returns a NACK immediately after detecting a failure in the communication with the controller (see ”4.2.2. NACK”). If the host receives a NACK, it must stop sending the current remaining command immediately and execute the recovery process such as retry.

  6.  **Command Interval time**
    * Interval time between Characters from a controller must be less than 5ms. The device sends NACK when 5msec passed before the device receives the next character code.
    *  Interval time between Commands is more than 30 ms.

In case of less than 30 ms as interval time between commands,

      1. Executing the subsequent command is not guaranteed.
      2. When there are buffer spaces of a device for a command, the device will execute the command.
      3. When there is no buffer space of a device for a command, the device does not execute the command, and will send Busy (@0BDERBUSY) to the host instead.![TASCAM-BD-MP4K-Control-I-O-Terminals-09](https://manuals.plus/wp-content/uploads/2022/09/TASCAM-BD-MP4K-Control-I-O-Terminals-09.png)
4.  **Basic Control Flow**
  1. Device Control Flow

The device sends the controller an ACK (Acknowledgement) and executes that command when the device receives a Control command from the controller. The list of the Control command is shown in “ 5. Command TableIf the device receives an unknown command or an End Character ‘CR’ (0x0D) without a Start Character ‘!’, it causes transmission failure and the device returns a NACK. Refer to ” 4.2.2. NACK ” about NACK transmission condition.

  2.  **Status Request Flow**

The device returns an ACK and the ANSWER requested by the controller when the device receives the Status Request from the controller. The list of the Status Request and the corresponding answer is shown in 5.3. Current Status Request TASCAM-BD-MP4K-Control-I-O-Terminals-11 When a device receives Status Request from a controller, the device sends an ACK to the controller. After that, the device gets the current status, and then sends it to the controller. If the device receives an unknown command or an End Character ‘CR ’ (0x0D) without a Start Character ‘!’, it causes transmission failure and the device returns a NACK. Refer to 4.2.2. NACK ” about NACK transmission condition.

  3.  **Status Notification Flow**

A device notifies of Status Information listed in “ 5.3. Current Status Request ” whenever the status of the device is changed, such as the transport status, the current track, the storage media status, and other status . TASCAM-BD-MP4K-Control-I-O-Terminals-12 A device sends Status Notification to a controller. The controller replies ACK to the device. The device waits for the ACK for Max 30ms. When the device does not receive the ACK from the host, the device sends the same Status Notification to the host again. After that, the device does not send the same Status Notification even if it does not receive an ACK from the host.
The Status Information is same as the answer for the Status Request listed in “5.3. Current Status Request”.
