System Planning and Specification

• To contribute to an optimal operating temperature, where possible keep this device out of direct sunlight.
• Any twisted pair, 120ohm, shielded EIA-485 cable is suitable to transmit DMX512 data to or from the DIN RDS4. The DMX cable should be suitable for EIA-485 (RS-485) with one or more low capacitance twisted pairs, with overall braid and foil shielding. Conductors should be 24 AWG (7/0.2) or larger for mechanical strength and to minimize volt drop on long lines.
• A maximum of 32 devices should be used on a DMX line before re-generating the signal using a DMX buffer/ repeater / splitter.
• Always terminate DMX chains using a 120Ohm resistor to stop signal degradation or data bounce-back.
• The maximum recommended DMX cable run is 300m (984ft). ENTTEC advises against running data cabling close to sources of electromagnetic interference (EMF) i.e., mains power cabling / air conditioning units.
• This device has an IP20 rating and is not designed to be exposed to moisture or condensing humidity.
• Ensure this device is operated within the specified ranges within its product datasheet.

• Always use suitable personal protective equipment when installing ENTTEC products.
• Once installation is completed, check that all hardware and components are securely in place and fastened to supporting structures if applicable.

Installation Safety Guidelines

• The device is convection cooled, ensure it receives sufficient airflow so heat can be dissipated.
• Do not cover the device with insulating material of any kind.
• Do not operate the device if the ambient temperature exceeds that stated in the device specifications.
• Do not cover or enclose the device without a suitable and proven method of dissipating heat.
• Do not install the device in damp or wet environments.
• Do not modify the device hardware in any way.
• Do not use the device if you see any signs of damage.
• Do not handle the device in an energized state.

Physical Dimensions

Mounting Options

Note: The surface mount tabs have been designed to hold the weight of the RDS4 only, excess force by caused by cable strain can cause damage.

Wiring Diagrams

• To reduce the likelihood of voltage or Electro Magnetic Interference (EMI) being induced on the OMX lines, where possible, run control cabling away from mains electricity or devices that produce high EMI, (i.e., air conditioning units).
• The maximum cable distance OMX can be run without re-buffering is 300m (ft 984ft).
• Never exceed 32 devices in a OMX chain without an intermediary OMX splitter (i.e. another DIN RDS4).
• Terminate all OMX chains to eliminate signal bounce back. This can be done by wiring a 120 Ohm resistor between Data+ and Data- or with a ‘OMX terminator’.
• To ensure a reliable connection, ENTTEC recommends the use of cable ferrules for all stranded cables connected to the DIN RDS4’s screw terminals.
• When using multiple DIN RDS4 units to increase the number of OMX input ports on your installation, do not double wire Inputs together for the input, (thereby making a pass-through). Instead, use one of the four outputs to connect to the next RDS4 input. Using the input as a passthrough will likely result in ‘ROM clashing’.
