CONNECTING THE MODEL 2090
POSITIONING CONTROLLER
Any combination of primary devices (towers, turntables,
reverberation paddles, MAPS, etc.) can be connected to the two
Device Interface ports located on the rear panel of the Model 2090
controller. For easy set up of an EMC facility, it is recommended
that the turntable be connected to the Device 2 interface port. The
controllers default settings are for a tower connected to the Device
1 interface port and a turntable connected to the Device 2 port.
Primary device connection is accomplished by way of 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; either end can be connected to the controller. A fiber
optic cable that is connect to the IN port of a device should, at the
other end, be connected to the primary OUT port of the motorbase.
A fiber connected to the OUT port of the device should, at the
other end, be connected to the primary IN port of the motorbase.
Older motor base designs have only one fiber optic connector pair,
while the newest motor base interface provides a secondary
interface reserved for future expansion.
NOTE:
Fiber optic cabling for each device should not be allowed
to hang unsupported from the rear panel of the controller. 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.
Using the Model 2090 Position Controller (or hand controller),
rotate the motor base shaft to verify proper operation. Run the
motorbase down to the lower limit CCW and then back it off from
the lower limit just a bit. This step will help after the turntable is
attached to the motorbase and it is time to set the rotation limits for
the turntable.
CAUTION
The soft rotational limits in the Model 2090 controller
must be set. Ensure the travel limit settings will not cause damage
to user installed cables and equipment mounted on the table.
