MADD-24

(Multiple Application Dimmer Driver)

The MADD-24 is the central electronic control system (aka brain) for all JS-ICON

Series dimmer racks.

The MADD-24 is located on the right-hand side of the dimmer rack, and mounts into card edge connectors

located on the Signal Distribution Board. The MADD-24 can easily be removed by unscrewing two #4-

40 mounting screws (use a small sized #1 Philips screwdriver) located on the top corners, and pulling

it forward using both hands. When re-installing a MADD-24, be sure it is fully seated into the card edge

connectors, and the two mounting screws are screwed in tight.
Located on the MADD-24 is a removable EEPROM memory module. The EEPROM memory module

slides into the PORT1 connector located on the upper center of the board. The EEPROM memory module

is used to backup important configuration settings and may be removed for safe storage. The EEPROM

memory module can also be used for firmware updates. Refer to menu items “EEPROM”, “FW-LOAD”,

“RESTORE” and “BACKUP” on page 27 to 29 for further details.
