• Faders: These represent the station's virtual faders. Faders can be set to any level from zero
to full on (100%). Each virtual fader also has a virtual LED, which is also a read-only
property.
• Rates: The station also utilizes fade rates to facilitate smooth and level transitions given the
limited bandwidth of RS232. There is a configurable rate that corresponds with each fader
of the station. When a new fader level is given, the fader is moved at the set rate to the
new level. Rate is set in a unit of seconds.
• Levels: A Level is a configurable feedback mechanism for up to 16 zones that report the
actual level of the configured zone to the serially connected device.
With Emphasis [Serial Button Protocol]
The Unison AV/Serial Interface has a second mode of
operation that interfaces with an Emphasis
Facepanel or ECS LPC via RS232 and Serial Button
Protocol. This mode of operation is set either by
installing the jumper on J2 to the “B” side (the
preferred method), or by sending a specified serial
command to the device. In this mode, commands that
set the LED state for buttons 1 thru 16 result in
activation of macros 101 thru 116 on the serially
connected Emphasis. Please see the Emphasis User
Manual (v1.4.0 or later) for more details about the
Emphasis Serial Button Protocol.
The Unison AV/Serial Interface station protocol as
defined in this document is still accepted from host to
station to allow any reconfiguration of the station. The
Unison Light Manager configuration must be
configured with the default AV/Serial Interface station
type (ST3300). Enabling Emphasis mode forces the
station to be the default type if it was previously changed; alternate station types are not
allowed. If the Unison configuration uses any other station, the physical station will not
bind/connect to the system.
Emphasis mode Light Manager configuration example:
The 16 buttons of the AV/Serial Interface station are configured as zone bump toggle for
zones 1 - 16. When zone one’s level changes from 0% to 100%, the AV/Serial Interface
station sends a command to execute macro number 101 of the serially connected
Emphasis system. Nothing is sent when zone one is returned to 0%.
