USB Port, RS232 Interface | Wisdom Wands SC-1 instruction

erly wired adapters are available from Wisdom Audio for an additional charge.

5USB Port

This USB port is used by your installer to connect a Windows-compatible PC for setup and calibration. It provides two-way communication between the SC-1 and the computer that is used for adjusting the many parameters of the system controller.

6RS232 Interface

The RS232 interface allows an external control system such as AMX or Crestron to control the SC-1. All basic operational modes are supported (operate, standby, selecting setup memories).

When the SC-1 is first powered up, it will identify itself to the control system via the RS-232 port, sending either

Wisdom Audio SC-1	or	Wisdom Audio SC-1
Ready...		ERROR

…depending on whether there is at least one setup memory that has been calibrated and is available for use. (For proper operation, at least one setup memory must be saved into the SC-1’s non-volatile memory.)

The commands available to your control system programmer are as fol- lows:

•OPERATE

•STANDBY

•EQ1

•EQ2

•EQ3

•EQOFF

Commands are terminated by either a CR (carriage return) or LF (line feed) character. Communication parameters are 9600, N, 8, 1. Responses to all commands are either OK or ERROR (as when trying to address a non- existent setup memory).

The calibration routines are not supported via the RS-232 port. Your in- staller will need to use the USB port for the calibration process.

712v Trigger In and Out

These 12v trigger jacks provide compatibility with a wide range of prod- ucts to facilitate remote turn-on and turn-off in systems. These 1⁄8" (3.5

mm)“mini-jacks” allow other components to bring the SC-1 in and out of standby. Two such mini-jacks are provided to allow “daisy-chaining” of this turn-on signal with other components, such as amplifiers.

The remote trigger input will be operated by any positive-polarity DC signal between 3–20 volts (only a few milliamps are required), with tip po- larity as shown below:
