System Configuration and Programming

EasyUSB Mixer/Amp:

The EasyUSB Mixer/Amp has an eight pin dip switch on the rear of the device for allowing installers to customize

product for the desired conferencing application. Available configuration functions are listed in Table below. The

“up” position on the dip switch represents enable and the “down” position represents disable.

Table: EasyUSB Mixer/Amp Dip Switch Configuration Settings

 Function Description

Default USBConference

Mode

This mixing mode sums the Line Input with the EasyMic audio and

sends it to the USB Transmit. The USB Receive is sent to the amplifier

output, Line Output, and AEC Reference. This will be the default mixing

operation when no switches are enabled.

1 RS‐232Mode

This mode switches the RS -232 port configuration from a DCE to a

DTE device. If DIP 1 is Down (disabled), the Mixer/Amp RS-232 port is

configured as a DCE device, allowing direct connection to a DTE

device such as a PC's RS-232 port or a WEBBi controller device. If

DIP 1 is Up (enabled), the Mixer/Amp RS-232 port will be configured as

a DTE device, allowing direct connection to a DCE device such

as the HD-USB camera. This switch setting takes effect immediately -

no power cycle required.
