New high-speed DMX512 multi-axis RS422 or RS485 protocol for JVL’s ServoStep™ motors

PRESS release: June 2021

Birkerød, Denmark - JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, can now deliver the DMX512 protocol on RS485/RS422 interface for all the
integrated stepper motors in their ServoStep™ series, from 0.3 to 25 Nm, sizes NEMA 17 to 43. DMX512 are mostly used for application in stage lighting, special effects and theatres but can also fast and efficiently control more than 100 motors from the same DMX master.
NB. With Cat 5 cables each system can control up to 32768 universes of DMX512 using the Art-Net protocol and each DMX512 Master universe has 512 channels. 
  • Virtually unlimited number of axes on the network using Cat 5 cables and the Art-Net protocol
  • Fast and efficient control of more than 100 motors using a single DMX512 master
  • Select DMX512 on the motors RS485 or RS422 channel
  • Advanced motion control tasks can be triggered from DMX512 commands
  • Dual supply motors with M12 connectors
  • Built-in ePLC™ with 8 I/O-points (or AI 0…5 V) for extra functionality
  • Communications diagnostics available in the MacTalk® software
  • Jogging using digital inputs
  • For OEM’s bespoke functionality can be developed
  • Available on all ServoStep™ motors
  • Theatre and stage lighting control for focus, color, intensity
  • Low cost control of water flow valves
  • Pan and Tilt of lighting fixtures
  • Triggering of advanced motion profiles by simple DMX512 input
  • Low cost high-speed multi axis control for any motion control application

8 IO-points are available locally on each motor, each point is selectable between DI, DO or AI (5 V). They can be used for home sensor signal or end limit inputs or other sensor inputs thus eliminating long cables to the DMX512 master. Local IOs can also be accessed via DMX512 commands. The DMX512 has a fixed communications speed of 250 kbit/s. It might not seem fast, but it enables sending new position data to 512 motors in just 16.4 ms. DMX512 has proved it’s worth in several stage and art projects with more than 200 axes. 
General DMX512 Information
DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the primary method for linking controllers (such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights. DMX has also expanded to uses in non-theatrical interior and architectural lighting, at scales ranging from strings of Christmas lights to electronic billboards. DMX can now be used to control almost anything, reflecting its popularity in theatres and venues. 
DMX512 employs EIA-485 (RS485) differential signaling at its physical layer, in conjunction with a variable-size, packet-based communication protocol. It is unidirectional. 
DMX512 does not include automatic error checking and correction, and so is not an appropriate control for hazardous applications, such as pyrotechnics or movement of theatrical rigging. False triggering may be caused by electromagnetic interference, static electricity discharges, improper cable termination, excessively long cables, or cables of low quality.
