Configuring the EMAP


Most L86 Installation Racks used for architectural control are shipped with specially customized settings for their EMAP modules. Your EMAP module is configured at the factory specifically for your dimming system.

If the module malfunctions and it is necessary to exchange it for a spare, be certain to adjust the jumper settings at location J3 on the spare so they match the settings on the original module. The illustrations to the left show the location of J3, and illustrate how to set the jumpers.

Jumper settings

A jumper consists of two or three vertical pins on the circuit board. A twopin 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 side pin. It is Off when the clip is removed or placed over just one pin.

Setting EMAP fade time

On systems that don’t include LCD control stations, Jumpers 1 through 6 at location J3 allow you to set the fade time for the EMAP. ETC sets Jumper 3 On for a default five second fade time. On other systems, Jumpers 1 through 6 at location J3 are generally left off.

Clear memory

Jumpers 7 and 8 at location J3 allow you to clear the EMAP’s memory (normally saved by a back-up battery). Set both jumpers to on and press the [Reset] button. The EMAP flushes out its memory and resets itself completely. Remove both jumpers and press [Reset] again to return the EMAP to active status.

Backup jumpers

If your module fails, you can temporarily continue to function by setting your module to Backup mode. This is accomplished by changing the jumper setting at location J18 from Left to Right (as shown to the left).

Setting the module to Backup mode connects your lighting console’s input directly to your dimmers, bypassing all the EMAP’s functions. Thus, if the EMAP has special configuration tables for dimmers, the console will not necesarily be able to address all dimmers while the module is in backup mode. In addition, house lighting control stations will not function.
