• The Mini-MOD is equipped with a 6-pin phone socket (RS485) to connect to extension panels. The Mini-MOD Extension is
equipped with two 6-pin phone sockets to connect to Mini-MOD and an additional Mini-MOD Extension.
• Set each Extension to a different letter (EXT-A or EXT-B). The Mini-MOD will assign the stage letters based on the extension letter
selected.
• Extension A will have its stage and Power LEDs Green. However, Extension B will have the LEDs Red. See "Mini-MOD-
Extension Layout" on page 7.
• Configure the Output Types (See "Output Type" on page 17.) after connecting the Extension panels to be able to configure their
outputs.
• Only use the cable provided.
• Connection cable is provided as part of the Mini-MOD Extension package.
