power to the station unless a suitable antenna or load is connected to the
transmitter output.
2.2 Mounting
The station is intended to be installed in a standard EIA “19 inch” rack. The
station is “one rack unit” high (or about 1.75 inches), and requires about 19
inches of depth to provide space for rear panel connectors. The station is
designed to draw fresh air in from the front panel and left front side panel, and
exhaust air from the rear and right rear side panels. So, the front and rear of the
station should be unobstructed to allow air to freely flow.
The 19 inch rack mounting brackets may be installed in any one of several
locations. 6-32 machine screws are provided to attach the brackets to the chassis,
and the brackets may be installed using the appropriate tapped holes, six per
bracket, located at the front, middle and rear of each side of the chassis.
Consequently, the station may be installed in a standard EIA 19 inch rack frame,
either from the front or the rear. The station may also be installed in an
“open-frame” rack where equipment is generally center mounted. DWC base
station cabinets further allow for simultaneous front and rear mounting to
provide additional earthquake stability, and have additional air filtering and
forced air cooling to allow for less than ideal air quality conditions.
It is highly recommended that the station be installed in one of the following (a) a
clean environment in a suitable rack cabinet, (b) in a DWC base station cabinet
(which itself has filtered air intakes and fans) or (c) other cabinetry with filtered
air intakes to reduce airborne particles being drawn into the base station fans.
Dirt and dust will not effect the operation of the base station other than reducing
the life of the fan bearings. Serious buildups of dirt and dust may cause the
transmitter or power supply to overheat.

There are several connectors on the rear panel:
DIGITAL AUDIO I/O
RS-232 serial port carrying digital audio, payload
