Unison® DRd Right I/O Card Upgrade Kit

Overview

The DRd Right I/O Upgrade kit is available to upgrade an existing DRd enclosure to be used with the
Unison Echo Architectural Control Processor.

Note:

Kit includes:

The DRd right I/O card and five 6-32 x .250 screws.

Required tools:

• No. 2 Phillips screwdriver

• Slotted screwdriver (optional)

Procedure

WARNING:

Preparation

Step 1: Turn off power to the DRd enclosure.

The right I/O card in this upgrade kit maintains compatibility for all existing Paradigm
and SmartLink Architectural Control Processors.

Power must be turned OFF when you perform this procedure. Before service,
de-energize main feed to dimmer enclosure and follow appropriate Lockout/
Tagout procedures as described in NFPA Standard 70E.

It is important to note that electrical equipment such as dimmer enclosures can
present an arc flash safety hazard if improperly serviced. This is due to available
large short circuit currents on the feeders of the equipment. Any work on
energized equipment must comply with OSHA Electrical Safe Working
Practices.

WARNING:

Failure to disconnect all power to the DRd before working in the enclosure
could result in serious injury or death.

Step 2: Loosen screws on the module retention rail on the left side of the DRd enclosure and slide

the rail to the left.

Step 3: If installed, remove the Architectural Control Processor, Station Power Module, and at

least three dimmer modules from the lower portion of the dimmer enclosure to provide
work space inside the enclosure.

Step 4: Use a digital voltmeter and verify that power is off by checking voltages for all

combinations between the phase bars, neutral, and ground (earth).

Note:

The connector plugs can be difficult to disconnect. Do not pull on any of the wires to
remove the connection. If you are having difficulty removing the connectors, carefully
use the edge of a slotted screwdriver to pry the connector free from the receptacle.

Retain this original right I/O card to verify DMX termination settings for the
replacement I/O card.

Once the upgrade is complete, this right I/O card is no longer needed and can be
recycled at a local certified electronics recycler or it can be sent back to ETC for proper
disposal. The circuit board should not be disposed of in the general trash.

setting based on your installation. You may refer to the old right I/O card to determine the
previous DMX termination settings.

• Source - reserved for future development

• Off - no termination, DMX will pass by this device to the next DMX device in the data
run

• End - termination is on. Used for the last DMX device (e.g. DRd enclosure) that is
