l Element Saving Limit Setting
l Fiber Optic Control Lines
l IEEE-488.2 I/O Port
l Speed Control Model 2090 Positioning Controller
ETS-EMCO’s Model 2090 Positioning
Controller
allows you to synchronize
simultaneous movement of two primary
ETS-EMCO devices (towers or turn-
tables), and on/off operation of up to
four auxiliary devices (LISNs, EUTs, etc.).
Independent operation of primary
devices can be performed manually, by
either of the two front panel controls, or
remotely, by a separate GPIB address for
each device. Fiber optic control lines
eliminate RF interference that can be
conducted through traditional wire cables.
The Model 2090 is designed to maximize
the features of ETS-EMCO antenna
towers and turntables. See page 4 for
information about retrofits to earlier ETS-
EMCO models and non-ETS products.
Functions
The front panel design of the Model 2090
features a user-friendly interface which
simplifies device control and clearly
communicates primary device movement
to the operator. Two separate sets of
controls (Device One and Device Two),
each with identical displays and functions,
are included. Other front panel features
include four auxiliary control switches and
the Model 2090 power switch.
Model 2090
A number of useful primary device
commands can be performed by the
operator. The SEEK function enables the
user to reposition a device to a new
target location and the SCAN command
initiates cyclic movement of a device.
The CONFIG and LIMIT functions
enable the user to program operational
parameters and upper/lower or clock-
wise/counterclockwise limits for each
device. The POSITION and STEP
functions work together to control tower
cross boom and/or turntable positioning.
Expanded details of these functions are
offered below.
SEEK & SC SEEK & SC SEEK & SC SEEK & SC SEEK & SCAN AN AN AN AN
SEEK allows a target location to be
entered to redirect the device from its
current location. Target locations can be
automatically incremented/decremented
by a given value. The SEEK command is
available only through the GPIB. All other
functions can be performed from both
the GPIB and the front panel. The SCAN
key initiates cyclic movement of a device
between pre-programmed limits. A cycle
is defined as movement from the lower/
counterclockwise limit to the upper/
clockwise limit and back to the lower/
counterclockwise limit. The total number
of cycles is programmable from 1 to 999
or an entry of “000” causes the device to
scan continuously.
CCCCCONFIG & LIMIT ONFIG & LIMIT ONFIG & LIMIT ONFIG & LIMIT ONFIG & LIMIT
The CONFIG (Configuration of Param-
eters) and LIMIT keys work together for
system set up. The CONFIG function
enables the operator to select six
operational parameters for both primary
devices.
The LIMIT keys allow the operator to set
upper and lower, or clockwise and
counterclockwise limits. The user simply
sets the limit by pressing the INCRM or
DECRM keys until the desired limit is
shown on the display and then selects
the ENTER key. To verify or set the
current position of a device under
control, the user can press the CURRENT
POSITION key.
POSITION & STEP POSITION & STEP POSITION & STEP POSITION & STEP POSITION & STEP
The POSITION and STEP functions
work together to manually position the
tower cross boom and/or turntable. Four
POSITION keys and two STEP keys are
available to achieve this control.
