RS-232/GPI
Mitto’s RS-232/GPI port is dual functioning. In the Config Menu you can set the function of the
RS-232/GPI connector to Console or to Memory Regs.
When set to Memory Regs, the D connector provides GPI outputs for use with an external control
panel, such as the Ensemble Designs Avenue GPI control panel (part number XYCP). External control
panels provide recall only, they cannot memorize settings.
When set to Console, the D connector provides RS-232 control for an external device to control Mitto,
such as AMX or Crestron.
See the following page for detailed pin out information.
Analog/Digital Audio In
Analog Stereo: This is a two-channel input using a standard 1/8” mini-jack. It can be connected
directly to the analog audio line level output of a tower, desktop, or laptop computer. If your computer
does not have a line level output, you can also use the headphone output of the computer. The level
of this output can depend upon several settings in the computer. The Windows or Mac OS X audio
control panels as well as the specific application software will both affect the output level. The general
recommendation is to set both of these controls to 80% of their maximum value.
AES or S/PDIF Digital Audio: Mitto can accept four channels of digital audio. A pair of digital audio
channels is carried in an AES or S/PDIF bit stream. Mitto can receive digital bit streams on the same
audio mini-jack connector. The channels 1/2 bit stream is received on the left input of the connector,
and the channels 3/4 bitstream is received on the right input of the connector. These inputs are
processed through sample rate converters which accommodate sampling frequencies from 44.1
to 96 KHz.
