Functions

The KNX-DMX Gateway has 1556 objects with three types of telegrams available:

• DPT 1.001 (1bit: switch) single channel
• DPT 1.001 (1bit; switch) save sequence and retrieve
• DPT 3.007 (4bit; relative dimming) single channel
• DPT 5.001 (1byte; show value) single channel
• The S2 rotary switch adjusts the transition period from one preset brightness to the next, 15 (F) being immediate, O a time period of 1 second from 0% to 100%.
• The S3 rotary switch automatically sets the dimming function parameters, O is no automatic dimming, other- wise dimming time = 1.5 sec * switch value (S3 = 1 .. 15 (F) ) in increments of 1% (dimming value 0111b or 1111b).
• The rotary switch settings will be prompted when starting and can be readjusted during operation by using the T1 button.
• Necessary requirements are a KNX bus, DMX 512 bus and a power supply.
• The KNX-DMX Gateway in REG casing IP20 is available in sizes of 6 DIN units.
• Firmware upgrades can be done via USB port.

Automatic Dimming Function:

• Automatic dimming function can be switched on or off for all channels using an object, or can be parameterized by S3 when booting up.
• Thereby the properties are controlled when dimming telegram (DPT 3.007) appears.
• Automatic function Off ( S3 = 0)
• A dimming object (4 bit) value range +7 .. -7 singularly reduces or increases the DMX value percentagewise.
• Automatic function On ( S3 <>0)
• A uniquely transmitted dimming setting is repeated during a time period (dimmer repetition) until it reaches a value of 0 or 100% or until it is manually stopped.
• When 100% is transmitted, the preset value in „dimming curve” is used (basic setting 1%).
• This function allows the integration of the KNX-Gateway for an installation with standard key buttons.
• A standard key button transmits a 100% upward or downward command in dimming function when pushed and held and a stop command when let go.
• A dimming setting can thus be set.
• The dimming time period can be adjusted separately using either the parameter repetition or the dimmer curve.
• The basic setting after booting up is 1% dimming.
• The repetition rate is controlled by the rotary switch S3 and gives a dimming time result of circa 1.5 sec switching value (S3 = 1 .. 15 (F).

Address Diagram

• The KNX-DMX Gateway is a master device in the DMX bus.
• It possesses an internal data memory and constantly transmits the data at a DMX rate of 250k baud to all 512 DMX channels.
• When receiving valid DMX telegrams the values in the memory are changed.
• The transfer of the KNX telegram is preconfigured so that individual programming is not necessary.
• The KNX data points are managed in 3 address rooms.
• That means that switching or dimming can be accessed on every channel.
• The group addresses diagram must be set up using the S1 rotary switch before initial operation (voltage supply).
• Changes become effective after a reset.
• The main group addresses from 0 – 15 are set up with the 16 stage rotary switch.
• The middle and lower group addresses are set by the predetermined address rooms (see table 1).
• The DPT 5.001 allocates the first 512 address on the KNX bus. After that the DPT 1.001 and DPT 3.007.
• Finally, the sequence commands, a test function and dimming parameters are coded.

Group Address Allocation Lower Group (bi-level KNX Address Room):
Set Channel Value:
Addresses 0 – 511
DMX bus.
with DPT 5.001 1 byte value ( 0 .. 100% )
To set a 1 byte value, use the lower group addresses 0-511 which correspond to the channels 1-512 on the Switch Channel Value:
with DPT 1.001 1 bit Value (Switching)
Addresses 512 – 1023
Using a switch, this function can be used to switch every channel separately.
When the value is 0 the channel is switched off (0), when it is 1 the saved value in sequence 8 is accessed and transmitted to the DMX512 bus.
Every DMX channel can be independently switched.

Group Address Allocation Lower Group (bi-level KNX Address Room):

• Before the values are transmitted, there must be defined values saved in Sequence 8.
• This is the case for default settings at the time of delivery (255 for all channels.
• To reset the default settings use either the defined value with DPT 5.001 (group address ×/0-511) or the function „Central On” (group address ×/1552) all values to 255.
• Then save this to Sequence 8 (group address ×/1551).
• This establishes a maximum value for every channel.

Dimming Channel: with DPT 3.007: 4 bit Value (Dimming)
Addresses 1024 – 1535

Table 1:
Possible Dimming Value as 4 bit Object:

• 0 =Stop
• 1 = 100% down
• 2 = 50% down
• 3 = 25% down
• 4 = 12% down
• 5 = 6% down
• 6 = 3% down
• 7 = 1% down
• 8 = Stop
• 9 = 100% up
• 10 = 50% up
• 11 = 25% up
• 12 = 12% up
• 13 = 6% up
