Power Cord
The motor base is provided with an input AC power cord that is approximately
2.45 m (8 ft) long. This power cord is suitable for portable or indoor applications
without modification.
Connecting the Model 2090
Any combination of primary devices (towers, turntables, reverberation paddles,
MAPS, and so on) can be connected to the two device interface ports located on
the rear panel of the Model 2090 Series Multi-Device Controller. For easy set up
of an EMC facility, it is recommended that the Model 2070B and Model 2071B
Antenna Positioning Towers be connected to the Device 1 port. The default
settings are for a tower connected to the Device 1 port and a turntable
connected to the Device 2 port.
Primary device connection is accomplished with a dual fiber optic cable included
with the device. This cable terminates into two ST connectors that are identical at
both ends. The cable is symmetrical, so either end can be connected to the
Model 2090. A fiber optic cable connected to the IN port of a device should be
connected to the primary OUT port of the motor base at the other end. Similarly,
a fiber optic cable connected to the OUT port of the device should be connected
to the primary IN port of the motor base at the other end. Older motor base
designs have only one fiber optic connector pair, but the newer motor base
interface provides a secondary interface reserved for future expansion.
Fiber optic cabling for each device should not hang
unsupported from the rear panel of the Model 2090. The fibers
and connectors are easily broken if twisted or bent. Keep the
fiber optic cables as straight as possible from the connector to
the protective sheath.
