Packaging & Contents
Each EDI-120 retrot control system is shipped in a custom designed box and packaging for
protection of the unit. It’s recommended to keep the box and packaging stored in a safe place. In
the unlikely event that the system needs to be returned to the JSI Factory, the packaging will help
prevent shipping damage and maintain warranty.
Each EDI-120 retrot control system includes all of the parts required to complete the retrot.
Parts included with the EDI-120 retrot control system:
• 10’ (3m) Belden 9829 (or equivalent) length of cable used to extend existing DMX cable(s).
• Two (2) 3-position breakaway connectors used to splice the existing DMX cable(s) to the
supplied DMX cable.
• Four (4) 1’ (30.5cm) extension ribbon cables used to extend the OEM P3, P4, P5 and P6
ribbon cables.
• 8’ (2.4m) #18 AWG green wire used to connect the EDI-120 retrot control system chassis to
earth ground.
• 5’ (1.5m) #18AWG yellow and brown wires used to connect the fan control wiring from the
OEM P1 connector to the fan SSR. Typical installations already contain the control wiring
within the OEM P1 connector wiring, and these wires are not required.
• 10’ (3m) yellow CAT 5e patch cable used to daisy-chain the DMX-A and DMX-B between
multiple EDI-120 retrot control systems. Only supplied when multiple EDI-120 retrot
control systems are purchased.

Installation
•
Disconnect (turn off) the power supply to the EDI Mark VII dimmer rack(s).
WARNING! Verify all power is disconnected (turned off) before proceeding.
Removal of the old EDI Control Module
• Remove the four (4) mounting screws securing the EDI Mark VII control
module.
• Carefully pull the control module forward until all of the rear wiring
connections are visible. Do not disconnect any wiring at this point.
• If you are not familiar with the EDI Mark VII control module electronics
and wiring, it is strongly advised that you take a few minutes to inspect
the OEM (Original Equipment Manufacturer) wiring (P1 through P6). If
the cables aren’t already labeled, label them using a permanent marker
(Sharpie).
P1 contains the AC power supply conductors (Neutral, Phase A, Phase
B and Phase C) used to power the control module, as well as the low
voltage fan control wiring (positive DC voltage control and common).
Observe the location of the P1 connector and compare it to the location
of the P1 connector on the EDI-120 retrot. If the P1 connector is
located on the opposite side, refer to the installation of the new EDI-120
retrot system for details.
On some earlier versions of EDI Mark VII dimmer racks, the fan
control was sensed from the house control inputs, and the fan control
wiring does not come through the P1 connector. If this is the case, the
fan control will need to be rewired from the P1 connector to the fan
SSR. More information regarding this modication is provided in the
“Installation of the new EDI-120 retrot system” section of this manual.
P2 contains the eld wiring connections for DMX and analog control.
NOTE: The P2 connection is obsolete when the EDI-120 retrot control
module is installed, and all the eld wiring must be terminated
on the back of the EDI-120 retrot control module. Refer to the
installation of the new EDI-120 retrot system for more details.
P3 contains the PWM output control signals for dimmers 1 through 36.
P4 contains the PWM output control signals for dimmers 25 through 60.
P5 contains the PWM output control signals for dimmers 61 through 96.
P6 contains the PWM output control signals for dimmers 85 through 120.
• All of the internal OEM wiring must remain intact to complete the retrot.
Compare these connections to the ones on the back of the EDI-120
retrot control module. Do not disconnect any wiring until you are
completely satised with how easy this is going to be.
NOTE: Never pull directly on the wires to remove connectors.
www.johnsonsystems.com 5
• Disconnect the P1 power connector/cable. Carefully squeeze the
latches on each side of the connector together to release the connector
and then pull the connector out. Inspect the connector and the
termination of the wires in the connector. Be sure everything looks okay.
• Disconnect the P2 connector/cable. This cable will not be re-used on the
EDI-120 retrot, so once the old control module is removed, it should
be coiled up, wire-tied and carefully set aside inside the dimmer rack,
making sure it is isolated from any AC line voltage.
• Disconnect the P3, P4, P5 and P6 connectors/cables. Again, be sure
not to pull directly on the ribbon cable to remove the connector as this
may cause damage. Carefully pull the connectors straight out.
• The old control module should now be free and clear of all connections,
and can now be completely pulled out of the dimmer rack and set aside.
• With the old control module removed, it is a great opportunity to do
some preventative maintenance. The dimmer rack should be thoroughly
cleaned, vacuumed and sprayed out using compressed air. All of the
AC line and load connections should be inspected and tightened if
necessary.
• Inspect the fan blower and be sure it spins freely. If required,
replacement fans are available.
Installation of the new EDI-120 Retrofit Control System
• Remove your new EDI-120 retrot control system from the box.
• Take a look at the eld wiring connections on the back of the EDI-120
retrot. There is a connector for DMX-A input, a connector for DMX-A
thru, a connector for DMX-B input, a connector for DMX-B thru, a
connector for four (4) 0-10VDC analog inputs, a connector for dry
contact inputs and a connector for +12VDC to power peripheral devices.
All of the eld wiring terminates on these connectors.
• Refer to the “Control Input/Output Connections” section on page 11 and
12 for details.
• On the old EDI control module (Multi-Link), the DMX input came through
the P2 connector. Since this connection/cable is now obsolete, locate
the DMX input and thru (if applicable) cable(s) coming into the dimmer
rack from the eld. Once the cable(s) has been located, disconnect
it. Inspect the cable(s) and ensure it will be long enough to reach the
connectors on the EDI-120 retrot, once it is installed. Two (2) 3-position
breakaway connectors and a 10’ (3m) Belden 9829 (or equivalent)
length of cable is supplied for extending the cable(s) if it isn’t long
enough. The cable(s) can now be dressed out and terminated on the
DMX-A input and DMX-A thru (if applicable) breakaway connectors
provided. Be sure to isolate and protect all shield wires and comply with
standard RS-485 termination practices.
• On the old EDI control module, the 0-10VDC analog inputs came
through the P2 connector. Since this connection/cable is now obsolete,
locate the analog input cable(s) coming into the dimmer rack from
the eld. Note the EDI-120 retrot only has four (4) 0-10VDC analog
inputs, versus ten (10) on the old control module. Once the analog input
cable(s) have been located, disconnect them. If required, extend the
cables. The cable(s) can now be dressed out and terminated on the
analog input breakaway connector provided.

www.johnsonsystems.com
If more than four (4) analog inputs are required, additional equipment may be necessary to
facilitate them. Consult the factory for options and further information.
• Dress out and terminate any applicable connections for the input/output contacts on the
breakaway connector provided.
• Dress out and terminate any applicable +12VDC power supply connections on the
breakaway connector provided.
• The intention is for the DMX input receptacle (5-pin male XLR) on the front of the EDI
dimmer rack to be connected to the DMX-B input on the EDI-120 retrot. To do this, the
existing wires connected to the XLR must be disconnected, and an applicable length of the
supplied 10’ (3m) Belden 9829 (or equivalent) cable must be reconnected to the XLR on one
end, and terminated on the DMX-B input breakaway connector provided on the other end.
Be sure to isolate and protect all shield wires and comply with standard RS-485 termination
practices.
Alternatively, the DMX-B input and thru connectors can be used for other purposes.
• Conrm all applicable eld wiring is terminated on the breakaway connectors provided. For
future reference, be sure all cables are labeled using a permanent marker (Sharpie).
• Inspect the OEM P3, P4, P5 and P6 ribbon cables and determine if they are long enough
to easily connect to the EDI-120 retrot. Four (4) 1’ (30.5cm) extension ribbon cables have
been provided to extend the OEM ribbon cables for ease of installation. When connecting,
be sure the OEM ribbon cable connector is fully seated in the provided extension ribbon
cable connector.
• An 8’ (2.4m) #18 AWG green wire has been provided for connection of earth ground to the
EDI-120 chassis. One end of the ground wire has a 0.250” female disconnect, and connects
to the male on the back of the EDI-120 retrot. Locate a place inside the dimmer rack
chassis to connect the other end of the ground wire. Cut the wire to length, dress it out and
connect (fasten) it to the dimmer rack chassis.
WARNING: Ensure chassis is connected to earth ground.
• On some earlier versions of EDI Mark VII dimmer racks, the fan control was sensed from the
house control inputs, and the fan control wiring does not come through the P1 connector. If
this is the case, the fan control will need to be rewired from the P1 connector to the fan SSR.
5’ (1.5m) #18AWG yellow and brown wires have been provided to implement fan control
from the EDI-120 retrot via the P1 connector to the fan SSR. For the yellow (fan control V+)
wire, the female pin on the one end inserts into pin 5 of the P1 connector and the other end
terminates to V+ on the fan SSR. For the brown (fan control V- (common)) wire, the female
pin on the one end inserts into pin 6 of the P1 connector and the other end terminates to V(common) on the fan SSR. Refer to page 10 for the P1 power connector pinout information.
• There are two (2) locations on the back of the EDI-120 retrot where the P1 power
connector/cable can be installed - one (1) on the right-hand side and one (1) on the left-hand
side. When looking at the EDI-120 from the rear view, the P1 connector is installed on the
left-hand side location (more common) by the factory. Have a look at which side the power
cable comes out in the dimmer rack and determine if the P1 connector needs to be moved to
the right-hand side location.

If the connector needs to be moved, follow the following procedure:
First, remove the ten (10) #4-40 x 1/4” mounting screws that fasten the
lid onto the EDI-120 chassis. Remove the lid and set it aside, along
with the screws. Remove the metal cover plate on right-hand side P1
location by unscrewing the two (2) #4-40 x 1/4” mounting screws. Set
the cover plate aside, along with the screws. Release the P1 power
connector by carefully squeezing the tabs on each side of the connector
together and pushing the connector back. Cut and remove the wire-tie
securing the cable to the EDI-120 chassis via the bridge lance located
on the front-side of the chassis. The P1 connector/cable can now be
moved to the right-hand side location. Neatly route the cable and then
clip the P1 connector into place. Be sure the P1 connector is fully
seated and secure. Use a wire-tie to secure the cable to the chassis –
there is a bridge lance located above the power supply on the front-side
of the chassis. Reinstall the cover plate over the P1 connector opening
on the left-hand side of the chassis. Reinstall the lid.
• A 10’ (3m) yellow CAT 5e patch cable is supplied to daisy-chain the
DMX-A and DMX-B between multiple EDI-120 retrot systems, in multirack installations and racks containing more than 120 dimmer circuits. If
applicable, route the cable into place.
• Everything should now we prepared and ready for nal installation of the
EDI-120 retrot.
• Put the EDI-120 retrot into a position where all the eld wiring and
OEM wiring can be plugged in.
• Connect (plug in) in the green ground wire onto the EDI-120 chassis
connector.
• If applicable, connect (plug in) in the yellow CAT 5e patch cable.
• Connect (plug in) the prepared DMX input and thru connectors.
• Connect (plug in) the prepared input/output contacts connector.
• Connect (plug in) the prepared analog input connector.
• Connect (plug in) the prepared +12VDC power supply connector.
• Connect (plug in) the OEM P1 power connector.
• Connect (plug in) the OEM P3, P4, P5 and P6 ribbon cable connectors.
• All of the eld wiring and OEM cables should now be connected
(plugged in).
• Be sure all connections are secure and fully seated.
• Slide the EDI-120 retrot along the guide rails and into place. Be sure
not to pinch any of the cables.
On some earlier versions of EDI Mark VII dimmer racks, the guide rail
opening for the EDI-120 retrot may be much narrower. If this is the
case, the guide rails will need to be removed. Once the guide rails are
removed, the EDI-120 retrot will need to held in place and secured
using the mounting screws provided.
• Secure the EDI-120 retrot using the four (4) #10-32 x 3/8” mounting
screws provided.

Turn on and test the new EDI-120 Retrofit System
• Connect (turn on) the power supply to the EDI Mark VII dimmer rack.
• Verify the operation of the system status LED indicators, LCD display
and programming switches.
• Refer to the programming section of this manual for system
conguration.
• Test the system thoroughly to ensure all wiring terminations are
functioning.
• Verify all of the dimmer control outputs have the correct phase
referencing. If a dimmer control output is patched to the incorrect phase
reference, the dimmer will not dim correctly and will go to full output at
around 1% DMX input. The factory conguration for EDI-120 retrot
systems is for 3-phase applications, with the dimmer phase reference
patch set at AABBCCAABBCC... For true single-phase applications
with the phases 180° out of phase from each other, set the default
(DEFAULT) menu phase patch to phase patch 2 (ØPATCH2). The
phase patch (Ø-PATCH) menu must be used to congure non-standard
applications or for single-phase applications with the phases 120° out of
phase from each other.
• Verify the fan blower is operating properly. The fan blower should turn
on with between 6-7% DMX or analog control - when DMX or analog
control drops below 6-7%, there is a 5 minute timeout on the fan blower
blower to ensure the dimmers have been cooled sufciently.
