AS-42L END VIEW
OPERATION
NORMAL MODE (Non-Chaser):
A green LED in the end panel will indicate that a valid LMX-128 control signal 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 channels 1-4. Raising the
switch on the far right will set the dimmer to respond to channels 5-8. A complete table of channel assignments
is provided in this manual. You can address up to 512 channels with multiplex 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.
The UP position of the switches invokes RELAY MODE.
CHASER MODE:
When operating in the chaser mode the AS-42L 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 chase 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.
