4 General Description

The intention of the SDP-40 serial port and protocol communication is for an external connected HOST to control and obtain status from the SDP-40. The protocol has been designed to focus on two specific goals. The first is HOST uploading and downloading of SDP-40 configuration, and system/effect setups. The second is HOST control of basic user adjustable parameters. (i.e. input, volume, balance…)

HOST

Rs-232 Serial Link

JBL Synthesis SDP-40

JBL Synthesis SDP-40 Serial Communications Protocol Printed on: 01/11/02

The SDP-40 uses simple notification, command, response and acknowledgment packets to have communication transactions with a given HOST. This protocol is designed for point to point communication between a HOST and SDP-40. The SDP-40 Protocol is a 3 layered system. The SDP-40 serial protocol allows for the SDP-40, or the HOST, to initiate a communication transaction. Most transactions are initiated by the HOST. SDP-40 then responds to the HOST command with either a response or acknowledgment packet. There are a few asynchronous notifications that SDP-40 initiates indicating system changes. Each transaction initiated must wait for a corresponding response before initiating the next transmission.

The 3 protocol layers are: Physical, Data Link, and Application Layers.

The SDP-40 Serial Protocol attempts to be as backward compatible with the SDP-3 as possible. This document will try to inform the user/programmer of the consistencies and differences between the SDP-3 protocol and the SDP-40 protocol. The basic structure of the protocol has not changed. A number of command/responses/notifications packets have been implemented exactly as they were in the SDP-3. These commands may not fully exercise the functionality of the SDP-40 (i.e. SDP-3 has 8 inputs that have been mapped to 8 of the 12 inputs on the SDP-40, SDP-3 IR codes are not the same as SDP-40 IR codes) In the case of these commands additional SDP-40 commands have been added to fully implement the SDP-40 functionality. In addition, some of the inter nal structure of the SDP-40 has forced the protocol to be unable to support some SDP-3 commands. These commands have been totally replaced with new commands that provide more control over the SDP-40 than was capable in the SDP-3. (Parameter Set/Get commands)

5.2 Serial Port Driver

SDP-40 serial port has been setup to operate as follows:

Operating Mode: Full Duplex Baud rate: 19.2K baud Data Size: 8 bits (1 byte) Parity: Odd Stop Bits: 1

5.3 Errors

The SDP-40 will detect parity, framing and data overrun errors. If any of the physical layer error s are detected, the complete packet is corrupted and the SDP-40 will reset the transaction and begin to look for a start of packet byte.

5.4 SDP-40 Receive Buffer

The SDP-40 has an internal receive buffer. The buffer is 256 Bytes and will transmit a NAK packet with an error code of DC_ERR_BUFFER_FULL to the HOST if the buffer is full. If the buffer is full, all data transmitted to the SDP-40 will be ignored. Therefore, making the currently transmitted packet, if partially transmitted invalid.

5.5 SDP-40 Hardware Verification (Not Supported in SDP-40 V1.00, V1.01)

This test verifies the RS232 ports are working by comparing the transmitted signal (at pin 2) to the received signal (at pin 3). The SDP-40 transmits a known test signal just following a power up. The SDP-40 monitors the serial port receivers while transmitting the test signal. If the signals are the same, the test passes. In order to test this circuit, RS232 Wraparound plug(s) are needed and must be installed at the female D9 connector(s) on the rear panel of the SDP-40 labeled “RS232”. The wraparound plug shorts pins 2 to 3, allowing for the SDP-40 to receive the signal it is transmitting. Once installed, power cycle the SDP-40 and verify the following message is displayed on the FPD:

JBL Synthesis SDP-40 Serial Communications Protocol Printed on: 01/11/02

SERIAL PORT A PASSED SERIAL PORT B PASSED

This message is displayed for about 2 seconds before entering normal operating mode. If no messages are displayed, then both wrap tests failed.

6 Data Link Layer

The data link layer is used to define a transmission packet. The layer appends a header and tail that encloses the transmitted application packet data. The data link header will contain the start of packet byte and count of bytes to follow. The data link tail will contain the end of packet byte.

Data Link Header: Byte Number Description Value

First Byte(0) Start of Packet (SOP) 0xF1 Byte(1) DLL Data Count nn

Application Heade r: Byte(2) Command nn Byte(3) APP Data Count (number of application data bytes to Follow) nn

Application Data: Byte(4) Data[0] nn Byte(5) Data[1] nn … Data[…] nn Last Data Byte -1 Data[Data Count -1] nn

Data Link Tail: Last Byte End of Packet (EOP) 0xF2

6.1 Errors

If the number of DLL data bytes received is the same as the data count and an EOP has not been received, the SDP-40 responds by transmitting a NAK packet with an error code DC_ERR_INVALID_PACKET. The SDP-40 then continues to look for a SOP byte and will not process the erroneous application packet. The HOST can use this as an indicator to retransmit the corrupted packet.

In addition, each byte of a packet must be received sequentially and within the INTER_PACKET_TIME. If any of the bytes within a packet transmission exceeds the INTER_PACKET_TIME, the SDP-40 will respond by transmitting a NAK packet with an error code DC_ERR_INVALID_PACKET. The SDP-40 then continues to look for a SOP byte and will not process the erroneous application packet. The HOST can use this as an indicator to retransmit the corrupted packet.

7 Application Layer

7.1 SDP-40 Asynchronous Notification Packets

SDP-40 has been designed to transmit the asynchronous notification packets following these system changes:

1. Power On

2. Entering Standby

3. Front Panel Display update

4. Parameter Value Changes.

The notification packets are defined as follows:

7.1.1 Wakeup Notification (SDP-40, SDP-3)

By transmitting the Wakeup Notification, SDP-40 indicates the unit has just “powered on” or reset and is ready to receive host commands. This notification is primarily for the HOST to know the status of the SDP-

40.

7.1.1.1 Notification Packet Description

Application Header: Command DC_WAKEUP 0x01 Data Count 0 0x00 Application Data: N/A

7.1.1.2 Host Response

The SDP-40 does not expect any response from the HOST.

7.1.2 Sleep Notification (SDP-40, SDP-3)

By transmitting the Sleep Notification, SDP-40 indicates the unit is shutting down into a standby mode. Because the hard power switch could be activated independently of the SDP-40 system software, hard power down will not be notified. Acknowledgment of the Sleep Notification is not required. This notification is primarily for the HOST to know the operating status of the SDP-40.

7.1.2.1 Notification Packet Description

Application Header: Command DC_SLEEP 0x02 Data Count 0 0x00 Application Data: N/A

7.1.3 Front Panel Display (SDP-40, SDP-3)

SDP-40 will transmit the front panel display buffer following the update to the SDP-40 front panel display. The SDP-40 front panel display is 2 X 20 ASCII character display. The HOST can control the operation of this notification message by FPD internal control registers. Individual notifications can be enabled or disabled and the minimum transmit interval can be adjusted. Transmission of the display buffer is

JBL Synthesis SDP-40 Serial Communications Protocol Printed on: 01/11/02

asynchronous to other host/SDP-40 communicati on and will only transmit following the completion of any communication exchanges in progress or pending. The FPD control register command packets are described in section 7.3.14 Get FPD Control Registers.

7.1.3.1 Notification Packet Description

Application Header: Command DC_FPD 0x03 Data Count 42 0x2A Application Data: Data[0] - Data[21] Line1 ch ch ch… 0x00 Data[22] - Data[42] Line2 ch ch ch … 0x00

Line2

Data Type: Null (0x00) terminated ASCII character string. Max Length: DISP_LINE_LENGTH defined in Appendix G Protocol Constants.

The SDP-40 includes 8 custom characters that are defined to display increments of a display block . (i.e. Volume Bar) The custom characters are ASCII character codes 08 - 0F(hex). The codes are used as follows:

'08' - left 1 bar '09' - left 2 bars '0A' - left 3 bars '0B' - left 4 bars '0C' - Full Cell '0D' - Underscore '0E' - right 3 bars '0F' - not in use

7.1.3.3 HOST Response

The SDP-40 does not expect any response from the HOST.

7.1.4 SDP-3 Parameter Change (SDP-40, SDP-3)

SDP-40 will transmit predetermined parameter change notifications. If a parameter value is changed due to any user action or system action the SDP-40 will transmit the current value of the parameter that is changing.

This command has been maintained for backward compatibility with SDP-3. In order to maintain backward compatibility, the SDP-40 Parameters have been mapped to the SDP-3 parameters as described in the Supported System Parameters table listed below.

Application Notes and Examples

7.4 Box initializations:

7.4.1 SDP-40:

When the SDP-40 is powered on it will initialize the serial port and then transmit the DC_WAKEUP Packet, and look for an ACK from the HOST. Currently, if an ACK is not received, the SDP-40 continues to operate. This message is mostly for the HOST to know if the SDP-40 is in an operational state.

7.4.2 HOST:

When the HOST issues a HOST_WAKEUP Packet the SDP-40 responds with an ACK and then transmits the current FPD buffer with a DC_FPD notification. If the Host issues a HOST_WAKEUP command and does not receive the ACK it should assume it is not connected or the SDP-40 is not capable of responding on the RS232 and therefore further serial communications will not be possible. If the SDP-40 RS232 is capable of communicating, the SDP-40 will respond to a HOST_WAKEUP Command in any “Powered up” state including standby.

7.5 Getting System Wide Status and Setup:

TBD

7.6 Downloading the System Setup to the SDP-40:

TBD

7.7 Simple System Control & System Stat us:

The HOST can control the system via the IR commands thus making any direct IR code a direct command. Because of some limitations in the IR codes the HOST also has direct control over the system volume, balance, fader, effect selection, zone 2 volume, balance and input selection through dedicated commands.
