External I/O
2.4.2
J3 — RS232 Interface
This connector can be used for debugging or for in-field updating of the microcontroller code. To use this port for debugging, the SDI software
must be used. See Section 2.2.4, Debugger and Microcontroller Configuration for the proper jumper settings to use this interface.
2.4.3
J4 — Parallel Port Debugger Interface
This connector is used for the on-board Suite56 Parallel Port Command Converter. In conjunction with the Suite56 software, this interface
provides a high-speed debugger connection through the JTAG/OnCE port of the DSP. See Section 2.2.4, Debugger and Microcontroller
Configuration for the proper jumper settings to use this interface.

External I/O
J9 / J10 — Microphone Inputs
There are two microphone inputs available at 1/8inch microphone connectors J9 and J10 labeled MIC1 and MIC2. These can also be
monitored via headphones by switching MIC1 and MIC2 on. The input levels of these can be adjusted with the potentiometers at RV1 and
RV2 labeled MIC1 LEVEL and MIC2 LEVEL. These signals are connected to the ADC2 A/D converter.
NOTE
If 1/4 inch to 1/8 inch adaptors are used for the microphone connection use only stereo-stereo or
mono-mono style adapters. Stereo-mono or mono-stereo adapters will result in a short of the
incoming audio signal to ground.
2.5.1.1
RV1/RV2 - Microphone Gain Control
These potentiometers control the input levels for MIC1 and MIC2 respectively. To prevent damage, always start with these controls in a low
setting, i.e., twisted left. These inputs can be monitored directly, using the on-board headphone amplifier.
2.5.2
J11 / J12 — Analog Outputs
Fixed pre-amp outputs (Variable through Digital Volume control on the DSP) are provided for 12 channels of output. These RCA connections
can be fed into a variable or fixed amplifier stage. Care should be taken to verify signal integrity before connecting to large fixed amplifiers
to avoid audible noise or speaker damage.
These outputs are located at J11 and J12.
