ETC L86 EMR User manual

L86EMR/EMAR
This manual describes ETC’s L86 EMR and EMAR electronics receiver modules. These two
L86 components are almost identical, the difference lying in the EMAR's ability to translate
multiple data formats. The EMR can only accept DMX512 control signal.
The EMR/EMAR electronics module is installed in the top center slot of the L86 dimmer
chassis. It receives dimmer output data from a lighting control console, then distributes
the data in DMX512 format to the rack’s EM64 electronics modules.
ETC configures the EMR/EMAR to customize the dimmer numbering within the chassis.
This allows chassis starting addresses other than the normal multiple of 48. The module
compensates for a mixture of dimmer types within the same chassis and can customize
the control curve for each dimmer. It can also be set by ETC to allow two consoles to
control two sets of lights independently, or two consoles to control the same lights with
highest level taking priority.
Generally, EMR/EMARs within installation racks are configured at ETC to match the
requirements of your system. For portable applications, standard configurations are
available without custom programming. For more details about standard and custom
configurations, see Configuring the EMR/EMAR on page 3.

Also, press [Reset] any time you install an EMR/EMAR into a system that has already
been turned on.
Fuse
To remove the fuse, push slightly on the center of the fuse cover with a screwdriver
and turn the cover counter-clockwise. Replace the fuse with type 3AG-1 only.

Indicator LEDs
When you first turn on your system (or press [Reset]) the module’s processor runs a series
of self tests. The LEDs turn on, then all flash together. Once the tests finish, the LEDs stop
flashing. Each indicator LED provides specific information about the operating status of
the module, as described below.

Note: If all LEDs flash simultaneously, the system has encountered a condition that makes
it impossible to function. Please contact ETC customer service at 608/831-4116 if this
happens. See Backup Jumpers on page 4 for more information.
Reset button
Press [Reset] any time you change the EMR/EMAR's internal jumper settings.
(See Configuring the EMR/EMAR on page 3 for more information on jumper settings.)

EMR/EMAR Users Manual 3
Configuring the EMR/EMAR
Most L86 Installation Racks and some L86 Touring Racks are shipped with specially
customized programming and non-standard jumper settings for their EMR/EMAR
modules. The following section describes jumper settings and configuration options for
non-customized systems only, except where noted. Customized systems include a
separate sheet noting your actual settings. If you have any questions, please contact
ETC Technical Service at 608/831-4116.
The modules are configured by adjusting settings on a bank of jumpers within the module.
Jumpers consist of either two or three vertical pins on the circuit board. A two-pin jumper
is On when a clip (a small, rectangular piece of plastic) is placed over both connectors
closing the circuit. It is Off when you remove the clip. A three-pin jumper is On with the
center pin connected to either of the side pins. It is Off when the clip is removed.
If the module malfunctions and you need to exchange it for a spare, be certain to adjust
all the jumper settings on the spare so they match the settings on the original module.
The circuit board illustrations on page 4 show the locations of all jumpers.
Selecting input data format
Jumpers 5 through 8 at location J3 allow you to select the incoming data format for
the module. Select the format by setting the jumpers according to the chart below.
Custom is the most common configuration for L86 racks. If you have a customized
system, your System Manual includes a separate page showing your actual EMR/EMAR
jumper settings.
K96 supports ten backups with 256 dimmers in each. AMX192 signals have filters to
remove excess noise.
The EMR lets you merge two incoming DMX512 signals into a single output signal. The
EMAR also lets you merge an incoming signal using a different protocol with a DMX512
signal into a single DMX512 output. The chart below indicates the jumper settings for
signals that combine the output types shown in the left column.

Setting starting address
Jumpers 1 through 4 at location J3 allow you to set the starting address for the
EMR/EMAR . Select the starting address by setting the jumpers according to the chart
below. Please note that the starting address and the dimmer number (as listed on your
console) do not necessarily correspond. If you need to make changes, write down
your original jumper settings for future reference.
Backup jumpers
If your module fails, you can temporarily continue to use the rack by setting the module to
Backup mode. Do this by changing the jumper settings at location J18 from Left to Right
(as shown to the left). You can also replace it with the EMRF module shipped with your
system for that purpose.
Standard jumper settings
The following table shows correct EMR/EMAR settings for all jumpers except those
at locations J3 and J18, both of which are discussed in Configuring the EMR/EMAR on
pages 3 and 4. Customized modules may have different settings, but you should never need
to change the settings on these jumpers except as instructed by ETC Technical Service.
Setting descriptions are based on module oriented as shown in the illustrations to the left.
