RDM
RDM (E1.20) is supported as standard on the DMX USB PRO Mk2.
Remote Device Management (RDM) is a protocol enhancement to USITT DMX512 that allows bi-directional
communication between the DMX USB Pro Mk2 and RDM compliant devices over a standard DMX line. This protocol
will allow configuration, status monitoring, and management of these devices.
Not all control software which has implemented the DMX USB Pro Mk2 as a device support RDM.
Standalone
The standalone mode built into the DMX USB Pro Mk2 allows the recording and playback of a DMX sequence/show.
The DMX USB Pro Mk2 Standalone Mode is limited to 1 Universe only and can be configured using the EMU software.
Recordings can be made either by using the DMX USB Pro Mk2’s DMX input or Art-Net through the connected
computers internal loopback IP address (127.0.0.1) or network.
The DMX USB Pro Mk2 only records the changing frames, to maximum the length of the recording. With 512 channels
(1 Universe) being recorded, with a frame rate of 40 fps with each frame being unique from the previous, the
maximum record length will be 100 seconds. If the number of channels or unique frames per second are halved, this
will double the maximum recording length.
The playback of the Standalone sequence/show can be triggered from within EMU or on Power Up of the DMX USB
Pro Mk2. Note: Upon opening EMU to access DMX USB PRO MK2, the standalone show will stop automatically. User
will have to power cycle device or select PLAY option for standalone show to continue playing.
The DMX USB Pro Mk2 draws its power from the USB connection. The DMX USB Pro Mk2 doesn’t require a computer
connection during Standalone Playback. The DMX USB Pro Mk2 can be powered through a 5v USB power adaptor,
allowing the DMX USB Pro Mk2 to be powered from the mains.
Any DMX generated by software which will output on the DMX port that is outputting standalone mode will stop
playing the sequence/show and output DMX as directed by the software.
