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
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 too much.
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. Find the
travel (mechanical) limit adjustment knobs on the side of the motor
base enclosure. To increase the amount of travel in either direction,
turn the knob in the direction indicated by the positive (+) sign. To
decrease the amount of travel in either direction, turn the knob in
direction indicated by the minus (-) sign.
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
