Initial Power-Up
The ROC will startup with all controls in a neutral position. If the surface is
connected to the Audio Engine then the engine will reset all the switches and
router assignments to the current values for the Control Surface port. The Control
Surfaces reflect the configuration of the Audio Engine port to which they are
attached so that the Control Surfaces may be easily interchanged.
Configuration of the Control Surface port is accomplished in conjunction with
configuration of the Audio Engine. The configuration software runs in Windows
95/98/NT and requires an available RS232 serial port on the computer to connect
to Port 4 on the AE-C2 card in the Audio Engine. See the section covering
operation of the software for details on Control Surface setup.
In the event of loss of power at the Control Surface, all switches and indicators
are returned to the same state as before the power loss when the power returns.
The same is true of power loss at the Audio Engine. When power returns the
Audio Engine will return to the same state as before the power failure. When
power is restored, the Audio Engine boot-up time is only a few seconds. Loss of
power at the Control Surface will not interrupt audio unless the current audio
source ends and the next audio source fader is OFF .
The Control Surfaces also incorporate a “Watchdog” timer which checks the
processor several times a second. In the event of a software error which locks up
the Control Surface, the lockup will be released by this watchdog in less than one
second.
To minimize the chance of program interruptions, use of an uninterruptible power
supply (UPS) is recommended for the Audio Engine. The ROC 5 and ROC 10
Control Surfaces consume approximately 25 watts of power. Select a UPS size to
provide the protection time you need.
