5.3. Operating via DyNet protocol
1.Unplug from the mains before installation.
.Connect LED modules to the fixtures.
Connect first fixture to the control panel which suports DyNet protocol.
3.Connect the DMX output of the first fixture in a data link with the DMX input of the second fixture. Always
connect output with the input of the next fixture until all fixtures are connected.Up to 3 fixtures can be con-
nected in data chain.
4.Insert the termination plug (with 120 Ohm) into DMX output of the last fixture in order to ensure proper trans
-
mission on the data link.
5.Connect fixtures to the mains
6.Select the DyNet protocol on all fixtures
(
menu SPE"---> Prt---> "dYn").
A description of each byte in the DyNet protocol is the following:
Byte 0: 1C - hexadecimal Logical Message
(fixed value)
Byte 1: 01 - Area
Byte 2: 00 – Channel level
Byte 3: 80 - Channel
Byte 4: ff – Channel Offset
Byte 5: 00 – Fade Rate
Byte 6: FF
(fixed value)
Byte 7: 1C Checksum
Area
- (0 to 255), as set on the Arcpower to give a unique address for each Arcpower unit (i.e. DMX base
address)
Channel Level
- (0 to 255), level - 01=100%, FF=0%
Channel
- (80 to 83), 80= channel 1, 81= channel 2, 82= channel 3, 83= channel 4, (see Channel Offset
if more than 4 channels)
Channel Offset
- (0-255), default (FF)- channel offset in blocks of 4: (FF = CH 1-4, 00 = CH 5-8,
01 = CH 9-12, etc up to 3E = CH 253-256 )
Fade Rate
- (0-255), fade rate with 1 second resolution (0= 0 seconds, 255= 255 seconds)
Checksum
- (0-255), checksum Byte - used to ensure the integrity of the packet.
Negative two's compliment of the preceding 7 bytes.
Example 1:
0x1C,0x10,0x00,0x80,0xff,0x05,0xff,0x5
This would control channel 1 (i.e. Red) of Arcpower unit, address 16 to a Level of 100% with a fade of 5
seconds.
Example :
0x1C,0x05,0xCC,0x8,0xff,0x0A,0xff,0x5
This would control channel 3 (i.e. Blue) of Arcpower unit, address 5 to a level of 20% with a fade of 10
seconds.
