Input/output connector

The input/output connector is Hirose DF11-18DP-2DSA(01) (18-pin header). The mating

part is a crimping socket DF11-18DS-2C with DF11-2428SCFA contacts. The

recommended adapter cable length should not exceed 10 inches.

Microphone input

The microphone input is designed to work with condenser microphones. A microphone

bias circuit is provided (2.5 V via a 2.1 KΩ resistor).

Audio line input

Line inputs are designed to work with standard input levels (0.707 V RMS). The input

impedance is 10 KΩ.

Audio line output

Line outputs provide output levels of 0.707 V RMS into a 10 KΩ load.

General purpose inputs/outputs (GPIO)

Note: These GPIOs are not accessible on model 2253P.
