power strip. The power indicator LED on the side of the CO2
will light.  Next, choose the CO2's mode of operation by
setting the slide switch in the side of the CO2.              For best results, when using the CO2 RCA jacks, use a
good-quality S/PDIF cable.  The cable should be coaxial

The CO2 has three different modes of operation:
? OPTICAL --> COAX.  Data at the optical input is converted
to coaxial output, and also copied "thru" to the optical        Figure 1 - Optical to Coaxial with Thru
output.  See Figure 1 for an example.  In this example, the
CO2 is a converter and a repeater.                                                 Device #1
? BI-DIRECTIONAL.  Data at the optical input is converted

to coaxial output, and data at the coaxial input is
converted to optical output.  Both conversions occur
simultaneously (also known as "full-duplex" operation).
This is the most popular mode.  See Figure 2 for an
example.  In this example, the CO2 is a bi-directional
converter.
