Model 1007 Merger Manual

OVERVIEW

Pathway eDIN Mergers combine two DMX
streams in a number of different ways,
depending on your application. The DIN form
factor makes installation fast and easy.
Modules may be cascaded together, up to
four levels deep.

CONNECTIONS

eDIN Mergers feature terminal strips that can be removed
from the module to facilitate wiring. Make the following
connections, WITH THE POWER TURNED OFF:

POWER

The module will run on a range from 9 to 30 VDC at
500mA per card connected. Observe the correct polarity
when connecting to the V+ and V-. A second set of termi­nals are provided on the connector to daisy-chain power
to other eDIN modules. A grounding terminal is also pro­vided for connection to earth ground.

DMX

DMX connections consist of a shield and one or two data
pairs. The two DMX IN usually come from control con­soles, architectural controllers or opto-splitters. DMX
THRU pins on each connector may be daisy-chained to
the DMX IN of other eDIN modules or other DMX equip­ment. DMX OUT sends the merged signal and is con­nected to the DMX inputs of the appropriate downstream
devices.
Connect the DATA+ and DATA– wires to D1+ and D1­respectively for each of DMX A, DMX B and DMX OUT.
Observe the same polarity convention throughout the sys­tem. Connect the cable shield to the SHLD COM terminal.
A DMX reference chart is provided on the next page.

CONTACT INPUT

Pins 4 and 5, on the same terminal strip as the DMX OUT
pins, may be connected to an external contact closure.
Closing the contact (shorting pins 4 and 5) forces a switch
from DMX A to DMX B in operating modes 7 & 8.

CONFIGURATION

The user interface has 2 operating modes: Function and
Edit. Press the ▲ or ▼ buttons to cycle through the
available functions: ADDRESS, MODE, UTIL, and TEST.
When the LED beside the desired function is lit, press
and hold the ENTER button until a dot appears at the bot­tom right of the numeric display. The card is now in EDIT
mode.
ADDRESS sets the DMX offset start-address for
modes requiring one. MODE sets the operating mode.
UTIL is reserved for future use. TEST toggles each output
channel on or off.
When done editing a parameter, press the ENTER
button again. The dot will disappear, the parameter will
be saved, and the card will be ready for operation.

Hint: You can press and hold the ▲ or ▼ buttons to
speed through values.

SET DMX ADDRESS OFFSET

Once in ADDRESS edit mode, press ▲ or ▼ to change
the DMX offset start-address to the desired value.
Press enter to save the new value.
DMX offset start-address is applied to the DMX B
input only, and its effect is dependent on the operating
mode of the module.

TEST MODE

Once in TEST mode, press ▲ or ▼ to cycle the display
from 1 to 512. The corresponding channel will cut to full
and hold. Press ENTER to exit test mode.
While in test mode, normal DMX input will be ignored
and only the test channel will be active.

SET OPERATING MODE

Once in MODE edit, use ▲ or ▼ to choose from:
Mode 1: HTP Merge with 2 second status quo
DMX A and DMX B are merged using a highest-takes­precedence comparison, on a channel-by-channel basis.
If DMX A channel 5 is at 10% and DMX B channel 5 is at
50%, the DMX output for channel 5 will be 50%. DMX B
input will start at the channel number set by DMX address
offset. If all DMX input is lost, the last DMX look is main­tained for two seconds then stops.
Mode 2: HTP Merge with 5 minute status quo
DMX A and DMX B are merged using a highest-takes­precedence comparison, on a channel-by-channel basis.
DMX B input will start at the channel number set by DMX
address offset. If all DMX input is lost, the last DMX look
is maintained for five minutes then stops.
Mode 3: HTP Merge with offset and 2 sec status quo
Input channels below the DMX address offset on DMX B
will be ignored. Channels above and including the offset
will be merged with their respective input channels on
DMX A using a highest-takes-precedence comparison, on
a channel-by-channel basis. If all DMX input is lost, the
last DMX look is maintained for two seconds then stops.
Mode 4: HTP Merge with offset and 5 min status quo
Input channels below the DMX address offset on DMX B
will be ignored. Channels above and including the offset
will be merged with their respective input channels on
DMX A using a highest-takes-precedence comparison, on
a channel-by-channel basis. If all DMX input is lost, the
last DMX look is maintained for five minutes then stops.
Mode 5: Auto Backup with 2 second status quo
DMX B is ignored as long as signal is present on DMX A.
If DMX A is lost, the output will immediately switch to
DMX B. If DMX A returns, output will immediately switch
back. If all DMX input is lost, the last DMX look is main­tained for two seconds then stops.
Mode 6: Auto Backup with 5 minutes status quo
DMX B is ignored as long as signal is present on DMX A.
If DMX A is lost, the output will immediately switch to
DMX B. If DMX A returns, output will immediately switch
back. If all DMX input is lost, the last DMX look is main­tained for five minutes then stops.

Mode 7: External Backup using a switch, 2 second
status quo. DMX B is ignored until the contact closure

input is closed (pins 4 and 5 on the DMX OUT shorted).
When the contact input is opened, DMX A is immediately
restored. Output source is controlled solely by the switch,
not loss of signal. If all DMX input is lost, the last DMX
look is maintained for two seconds then stops.

Mode 8: External Backup using a switch, 5 minute
status quo. DMX B is ignored until the contact closure

input is closed (pins 4 and 5 on the DMX OUT shorted).
When the contact input is opened, DMX A is immediately
restored. Output source is controlled solely by the switch,

not loss of signal. If all DMX input is lost, the last DMX
look is maintained for two seconds then stops.
Mode 9: Append with 2 second status quo
DMX B is appended to DMX A beginning at the DMX ad­dress offset. The appended channels are not merged. If
DMX input is lost, the last DMX look is maintained for two
seconds then stops. Ideal for consoles in different rooms
accessing separate ranges of the same dimmer rack.
Mode 10: Append with 5 minute status quo
DMX B is appended to DMX A beginning at the DMX ad­dress offset. The appended channels are not merged. If
DMX input is lost, the last DMX look is maintained for five
minutes then stops. Ideal for consoles in different rooms
accessing separate ranges of the same dimmer rack.
Mode 11: Test Mode with channel fade
Similar to TEST mode, only the selected channel fades
up and down. The default channel is the set by the DMX
address offset. If TEST is entered while in this mode, the
active channel can be selected using ▲ or ▼. DMX A
and B inputs are ignored while in this mode.
Modes 12 –15: Reserved for future use

DMX TERMINATE

The rules of DMX require the last device on a DMX line
be terminated with a 120Ω resistor between pins 2 and 3
to prevent signal reflection. The Merger module has ter­mination switches for both DMX A and DMX B. If there is
no connection to the DMX THRU terminals, the DMX Ter­minate switch for that input should be ON. If there are
other devices connected to the DMX THRU terminals, the
DMX Terminate switch should be OFF and termination be
applied to the final device in the daisy-chain.

REMOTE DEVICE MANAGEMENT

The #1007 eDIN Merger is not compatible with the E1.20
Remote Device Management (RDM) protocol. The RDM
standard has no provision for signal merging at this time.
