11.5.1. Serial Ports
The device is built with 3-pole Phoenix connector. See the examples below of connecting to a DCE (Data
Circuit-terminating Equipment) or a DTE (Data Terminal Equipment) type device:

11.5.2. Audio Ports
Inputs and outputs of audio devices are symmetric or asymmetric. The main advantage of the symmetric
lines is the better protection against the noise, therefore they are widely used in the professional audio
industry. Symmetric audio is most often referred to as balanced audio, as opposed to asymmetric, which is
referred to as unbalanced audio. Lightware products are usually built with 5-pole Phoenix connectors, so we
would like to help users assembling their own audio cables. See the most common cases below.

ATTENTION! Symmetric and asymmetric lines can be linked with passive accessories (e.g. special
cables), but in this case half of the line level is lost.

ATTENTION! There are numerous types of regularly used connector and cable types to connect audio
devices. Please always make sure that a connector or cable fits your system before use.

ATTENTION! Never join the phase-inverted (negative, cold or -) poles (either right and left) to the ground
or to each other on the output side, as this can damage the unit.

INFO: Use a galvanic isolation in case of a ground loop.

11.5.3. OCS Sensor
The switcher is supplied with a 3.81mm 3-pole 90° Reversed Gender Plug Phoenix
for connecting an occupancy sensor. The figure below is an example about how to connect a Leviton OCS10-
M0W device. This sensor is a so-called 'active-high' type, thus the setup requires an external 1kR pull-down
resistor between the input and the ground pins. If your sensor is 'open drain' type, the grey-colored wire and
the resistor is not recommended to install.
* The extra wire and the resistor are recommended only for 'active high' type sensors.
