#161330 - without any repeater Responding to: ???'s previous message |
Kai Klaas said:
Again, DMX uses a RS485 bus! It's intended to have all the receivers attached to the common RS485 bus, without any repeater. This, in contrast to MIDI, which needs a repeater between each "MIDI IN" and "MIDI Thru" connector. Which is exactly what it says in the link cited by Grant: http://www.pangolin.com/LD2000/dmx-about.htm said: (my added emphasis)
DMX512 is connected using a daisy-chain methodology where the source connects to the input of the first device, the output of the first device connects to the input of the next device, and so on. The standard allows for up to 32 devices on a single DMX link. Although each device has an input and output connector, these are merely wired together -- no re-transmission or amplification is performed by each device. |
