Dalcnet Easy DMX over UDP
(ETHERNET)
DGM01 allows to receive and/or transmit a RDM universe from/to other DGM01 or other devices through UPD protocol.
Just need to send a packet of 512 bytes on the configured UDP port (default: 1025) for the communication of 512 levels of light intensity.
Each byte represents a RDM slot. RDM slot is a RDM brightness level from 0 to 255. As there are 512 slots,
512 levels of brightness from 0 to 255 are controlled.
It is not necessary to send any other command, since the interface is able to process data by itself.
When you want to change brightness levels, you have to re-send the packet, otherwise the device will continue the transmission of last values
received.
For example, setting up:
send:
1° byte
2° byte
3° byte
...
512° byte
the first lamp to max level and the others off
255
0
0
...
0
the second lamp to max level and the others off
0
255
0
...
0
the second lamp to 50% level and the others off
0
128
0
...
0
Configuration
It is possible to set up a UPD receiving port and a UPD transmission port, or make a broadcast transmission.
The packets are transmitted with frequency fixed on “min scan time” every time that packets are received from Ethernet network or from field-
buses (RDM/DALI/MODBUS). If there are no variations, packets are periodically sent according to the time fixed on “max scan
time”. The zero value disables the periodical transmission.
