OPERATION

NORMAL MODE (non-chaser)

A green LED in the end panel will indicate that a valid control signal (DMX) is applied to the unit. A DIP switch

block on the end panel selects the starting channel number of the dimmer. The 7 right hand switches control this

function. For example, if all switch positions are down - the dimmer will respond to console channels 1-4. Moving

the switch position on the far right to up will set the dimmer to respond to channels 5-8. A complete table of

channel assignments is provided at the end of this manual. You can address up to 512 channels using DMX

control.

RELAY MODE: Pairs of channels (1/2 and/or 3/4) may be switched into the relay mode. In this mode the output

of these channels will be either off or full on depending on the control console channel setting. The trip point for

turn on is aprox. 50%. The 2 left hand switches on the DIP switch block control relay mode channel selection.

CHASER MODE

When operating in the chaser mode the AS-40D becomes independent of the control console and other dimmers.

The green LED indicator is OUT when in the chaser mode. Chaser mode is turned on and off by one of the DIP

switches on the end of the unit. A diagram on the unit cover shows the switch settings for controlling chaser

operation.

Eight different chaser patterns are available. A “bounce” condition may be imposed on several of the chase

patterns by setting one of the DIP switches. The bounce condition causes the chase pattern to run in alternating

directions.

The chase step time may be controlled for up to 64 seconds per step. Step fade time is proportional to the step

time. If a channel is in the relay mode during chaser operation - it will “snap” on and off (zero fade time). The

tables below show the details of chaser settings.
