Connect the HOT side of the secondary to the HI input on the BASR
and the LO side to COM on the BASR. All other half-wave devices
sharing the same AC power source need to follow the same convention.
When using a DC power source, connect the positive terminal of the
source to the HI input and the negative terminal to COM on the BASR.
Reversing polarity to the BASR will not damage the BASR.
WARNING: Devices powered from a common AC source could be
damaged if a mix of half-wave and full-wave rectified devices exist. If
you are not sure of the type of rectifier used by another device, do not
share the AC source with it.
Limited Power Sources
The BASR should be powered by a limited power source complying
with the requirements of the National Electric Code (NEC) article 725
or other international codes meeting the same intent of limiting the
amount of power of the source. Under NEC article 725, a Class 2
circuit is that portion of the wiring system between the load side of a
Class 2 power source and the connected equipment. For AC or DC
voltages up to 30 volts, the power rating of a Class 2 power source is
limited to 100 VA. The transformer or power supply complying with
the Class 2 rating must carry a corresponding listing from a regulatory
agency such as Underwriters Laboratories (UL).

Status: During boot-up, this LED flashes green. Once all files are
loaded, it glows solid green to indicate the unit is operational. If a
problem exists, it will glow solid red.
Ethernet: This LED glows if a valid link exists to an operating
Ethernet device. It indicates speed by colour: green for 100 Mbps and
yellow for 10 Mbps. It flashes to indicate activity.
I/O: Each of these LEDs glows green when the associated I/O point is
in normal condition. Depending on the programmed function, some of
these LEDs will glow red to indicate abnormal conditions. Refer to the
User Manual for a complete explanation of these LEDs.
