Technical Manual Multimedia Gateway SCN‐MMG01.01 2 Introduction The MDT Multimedia Gateway offers possibilities for connecting Multimedia devices to the KNX‐Bus. Connection between Multimedia Gateway and Multimedia device is established by a RS232 interface, which is included in delivery. The Gateway offers prepared settings for devices of the Companies Russound, Löwe TV and the T+A K8 series. Via the setting Universal Plaintext and Universal Hex other devices with the appropriate data format can be controlled. 2.1 Connector pin assignment Figure 1: Connector pin assignment MDT technologies GmbH • 51766 Engelskirchen • Papiermühle 1 Tel.: +49-2263-880 • Fax: +49-2263-4588 • knx@mdt.de • www.mdt.de... -

If one of the predefined producers is in use, this producer can be adjusted at this menu. There are predefined commands available for this producer, which can be used directly. The settings for the transfer should be made form the manual of the device.

Page 7: Header/Footer
Technical Manual Multimedia Gateway SCN‐MMG01.01 4.2 Header/Footer The following figure shows the settings for the Header and the Footer of the telegram: Figure 3: Header and Footer Because most of the producer use a fixed device identification at the begin and the end of the device as well as a Checksum at the end, up to three header and footer can be adjusted. The Header is put in front of the telegram and the footer is put at the end of the telegram. Which Header and Footer shall be used can be adjusted for each group of telegrams. There are two predefined settings for calculating the checksum: T+A/Metz and Russound. The checksum of T+A/Metz devices is calculated as follows: (Sum Byte 1‐5)/0xFF. The checksum of Russound devices is calculated as follows: (Sum of all command bytes + decimal value 6) masked with 0xF7. If other checksums shall be used, the checksum at the Header Footer menu must be deactivated and must be calculated for every command individually.

Figure 4: KNX => RS232 (1 Bit) The Group of the objects from 0 to 39 can transmit telegrams to the multimedia device as well at a 0‐ command as at a 1‐command. The Group of the objects from 40 to 79 can transmit telegrams to the multimedia device only at a 1‐command. The transmitted telegram contains of the adjusted Header (here H1) + the adjusted telegram + the adjusted Footer (here F1). 4.4 KNX => RS232 (1 Byte) The following figure shows the available settings for 1 Byte communication objects: Figure 5: KNX => RS232 (1 Byte) Received byte values from the KNX‐Bus can be transmitted to the multimedia device via the objects 80‐99. The character string “%1” in the telegram indicates that the Byte value is calculated into a relative value from 0 to 100% and transmitted as this to the device. The character string “#1” in the telegram indicates that the Byte value is transmitted directly as absolute value to the device. At this setting the KNX value is limited to 100.

At the objects 110 to 119 telegrams can only be adjusted for sending a logical 1. The whole telegram, with Header and Footer, must be adjusted for the status objects. The Header and Footer functions are not used at this group.

Technical Manual Multimedia Gateway SCN‐MMG01.01 4.8 Macro functions The following figure shows the available settings for the macro functions: Figure 9: Macro functions The Macro functions enable the sequential sending of multiple commands via activating one object. Up to 7 commands can be selected for each macro. For selecting the commands, the objects 0‐99 are available. Each object can be called with an individual adjusted value. The byte values are transmitted 1:1 and will not be calculated into a relative value. Additional can be selected which value (0/1) activates the macro function.

End of the telegram via the telegram: Figure 11: Example 1, general settings At this example, the length of the telegram is transmitted at the second byte, so the position of length specification is assigned to 2. To the end of the telegram (without checksum) are 3 bytes remaining (Offset of length specification = 3). So the whole length of the telegram is defined. The data end (timeout) can be adjusted to the minimum value, because the baud rate of the RS232 is 115200, which makes crossovers of telegrams impossible. The telegram example contains start values before the command and end values after the command. These values are adjusted for the Header and Footer. Figure 12: Example 1 ‐ Settings for Header At first the length of the Header must be adjusted. Now a value for the Header can be assigned, here 0103C4.

As option for this parameter the character %1 is set behind the value 0x00. So the value 00%1 must be signed in for this object. The option in combination with the telegram affects that the Byte value is calculated into a percental value and transmitted as this to the multimedia device.

The Header and the address (Byte 1 and 3) are inscribed 1:1 for the parameter. Byte 2: The length of the telegram (Byte 2) shall be taken from the RS232 telegram. So the Code $L is signed in, which indicates that the value for the length of the string is transmitted here. Byte 4 and 5: For taking the byte values for Status 1 and 2 (Byte 4 and 5) the codes #0 and #1 is used. So the values are transmitted 1:1 to the objects 120 and 121. Byte 6 – 22: The Clear text is transmitted with the bytes 6 to 22 with the maximum of 16 signs. The code $0 is signed in to transmit the character string to object 130.If a RS232 telegram with character string is send from the device, the Multimedia Gateway sends this content via the object 130 to the KNX Bus.

Page 18: Settings For Löwe Tv
Figure 17: Example 2, general functions For performing a command with a 1 Bit value, the Clear text values with the appropriate commands must be signed in: Figure 18: Example 2, 1‐Bit command So the TV is switched off by sending a “0” to object 0 and switched on by sending a “1” to this object. At this example the Multimedia Gateway can transmit a value for the loudness: Figure 19: Example 2, 1 Byte value With the Code %1, the Byte value is calculated to 0‐100%. So if you send the value 0x128 to the Byte object, the Gateway transmits the value 50% to the TV.
