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.
Starting address
Backup jumpers
Backup
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
J3
pages 3 and 4. Customized modules may have different settings, but you should never need
J12
to change the settings on these jumpers except as instructed by ETC Technical Service.
J16
Setting descriptions are based on module oriented as shown in the illustrations to the left.
