Model 2090 Positioning Controller

ETS-EMCO’s Model 2090 P ositioning
Controller allows you to synchronize

simultaneou s movement of two primary
ETS-EMCO devices (towers or turn­tables), and on/off operation of up to
four auxili ary devices (LISNs, EUTs, et c.).
Indep endent op eration of primary
devices can be performed manually, by
either of the two front panel controls, or
remote ly, by a separat e GP IB ad dress for
each device. Fibe r optic control line s
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 ETS­EMCO models and non-ETS products.

Functions

The front panel de sign o f the Model 2090
features a user-friendly int erface which
simplifies device control and clearly
communicates primary device movement
to the operator. Two separate sets of
controls (Device One and Device Tw o),
eac h wi th i de n ti cal di sp l a y s a n d fun cti o n s ,
are included. Other front panel feature s
include four auxiliary control switches and
the Model 2090 pow er swit c h.

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 com mand
initiates cyclic movem ent of a device.
The CONFIG and LIMIT functions
enable the user to p r o gram operational
parameters and upper/lower or clock­wise/counte rclockwise limits for each
device. The POSITION and STEP
functions work together to control to wer
cross boom and/or turn ta ble posi ti oning.
Expanded details of these functions are
offer ed be low.

SEEK allows a target location to be
entere d to redirect the device from its
current location. Target locations can be
automatically incremented/decremented
by a given value. The SEEK command is
available o nly through the GPIB. All other
functions can be performed from both
the GPIB and the front panel. The SCAN
key initiate s cyclic movement of a device
between pre-progr ammed lim its. A cycle
is defined as movement from the lower/
count erclockwise limit to the upper/
clockwise limit and back to the lower/
count erclockwise limit. The total number

of cycles is programmable from 1 to 999
or an entry of “000” causes the device to
scan c o nt in uo u sl y.

The CONFIG (Configuration o f P aram­eters) and LIMIT keys work together for
system set up. The CONFIG function
enables the operator to select six
operational parame ters for both primary
devices.

The LIMIT keys allow the op erator to set
upper and lower, or clockwise and
counterclockwise limits. Th e 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, t he user can press the CURRENT
POSITION key.

Features

Automatic Target Overrun Correction

The Model 2090 constantly monitors
inertia-induced target overrun. If
overrun on turntables or towers occurs, it
is identified and tracked. Utilizing a
special algorithm, the Model 2090
continually ad j usts s u bsequent
positionings to minimize overrun,
allowing for proper device positioning
during tests.

Element Saving Limit Setting

To preven t damage to antenna elements
which may accide ntally rotate into the
ground plane or ceiling during polariza­tion, the Model 2090 allows you to
program two upper and two lower limit
settings. These settings allow you to
safely maximize antenna scan height in
either horizontal or vertical polarization
– especially useful with BiCo niLogs
biconicals, log periodics, and other
antennas with protruding elements.

Fiber Optic Input/Output Lines

The 2090 features fiber optic control
lines to eliminate conducted noise. Each
primary device cable contains two fiber

Now your older ETS-EMCO tower and
turntable can operate with all of the new
command features available with our
Model 2090 Positio ning Controller. All
you need is our Retrofit-Kit and a Model
2090 Controller to replace your existing
EMCO Model 1050, 1060, 1060C or 1090
Controller . You'll be able to control two
devices (tower or turntable) and fo ur
auxiliary devices at once, plus access the
SEEK, SCAN, target overrun, and
multiple limit functions. For a thorough
description of all Model 2090 features
and functions please turn to page one.
Note: Bore Sight functions are only
availa bl e with Model 2071 towers .

To install the Retrofit-Kit, the included
interface box is placed in line between
the tower/ turntable motor box and

controller. Existing cables ar e used
between the tower/turntable motor box
and the Retrofi t-Kit's interface box. Fiber
optic cables are connected between the
interface box and the new Mo del 2090
