General Product Description
The ASC Signal Corporation, NGC Antenna Controller Outdoor Unit Models, all of which are designed to be used with
ASC Signal motorizable fixed antennas:
NGC-ODU-208-3 NGC-ODU-208-3-HA
NGC-ODU-208-5 NGC-ODU-208-5-HA
NGC-ODU-380-3 NGC-ODU-380-3-HA
NGC-ODU-380-5 NGC-ODU-380-5-HA
The ASC Signal NGC is a modular, scalable, adaptable advanced-level antenna pointing and tracking controller intended
for motorized satellite earth station antennas used with geosynchronous communications satellites.
The system is intended for new installations, and as a replacement for legacy control systems such as the ASC Signal
APC100, APC400, and ACS3000 systems.
The NGC provides the following basic and optional features:
Variable Speed motor control for two- and three-axis motor systems complying with the standard ASC Signal
interface, using VFDs for driving the azimuth and elevation axes.
Support for single phase AC polarization rotators.
Automatic positioning of antennas to pre-programmed look angles.
Optical Interfacility link
Local control from the indoor unit through an advanced touch panel LCD and keypad.
Local control from the outdoor unit through an advanced handheld unit
Automatic installation commissioning assistance
10/100 BaseT Ethernet interface for external M&Cs (via the IDU)
Remote control through network-based and serial-port-based communications protocols, including both legacy
protocols and SNMP.
Integral beacon receiver interfaces to support ASC Signal’s patented three-point peaking step-track and
SmarTrack® hybrid feedback/predictive program tracking algorithms.
NORAD and Intelsat program tracking
Optional integrated subreflector tracking (SRT) capability for high-accuracy Ka-band tracking, including hybrid
main dish and SRT positioning and tracking
The NGC is physically divided into an Indoor Unit (NGC-IDU) and an Outdoor Unit (NGC-ODU), connected by a dedicated
multimode optical fiber link. The NGC-IDU is a 3RU 19-inch rackmount chassis that is mounted inside the equipment
shelter or building. It provides the user interface and the interface to the tracking receivers. All NGC variants have the
same NGC-IDU package.
The NGC-ODU is packaged in multiple layouts based on application. All are generally mounted outside, on the positioned,
pedestal or tripod mount. Depending on the ordered chassis variant, the NGC-ODU may use 208VAC or 380VAC three-
phase wye power, or 230VAC single-phase power. The NGC-ODU may use common or separate sources for technical
and service power, as desired by the customer.
The functional allocation between NGC-IDU and NGU-ODU follows one basic principle: the indoor unit generates all
pointing commands and the outdoor unit executes them. All tracking functions are isolated to the NGC-IDU, which as
mentioned is indoors, where the beacon receiver or other signal measurement device will be located. All motion control
functions are isolated to the NGC-ODU, which is located on the positioner or pedestal, allowing the termination of all local
control cables after short runs and minimizing the interconnection between indoor and outdoor to AC power, transmit and
receive signals, and a single control fiber.

7580368_Rev D Page 6of 89
Unlike many previous systems, pointing commands from the NGC-IDU to the NGC-ODU are always given in horizon-
oriented coordinates (that is, true azimuth and true elevation). The NGC-ODU software performs all necessary coordinate
transformations to determine “local” azimuth and elevation position commands, and to provide feedback in both local and
horizon-oriented coordinate frames.
No configuration of the dedicated link between NGC-IDU and NGC-ODU is required. This avoids the need for the installer
to understand TCP/IP networking configuration.

I.VI Summary of Safety Precautions
The following safety precautions are not related to any specific procedure, and so will not appear elsewhere in this
manual. Ensure all personnel understand & apply these precautions in all phases of installation, operation, &
maintenance. Failure to do so may result in loss of life.
KEEP AWAY FROM LIVE CIRCUITS: Personnel must observe all applicable safety regulations at all times. Ensure
power is disconnected or removed from the unit BEFORE replacing any components. Potential hazards may exist even
though the power control switch is in OFF position. Capacitors retain electrical charges. Always REMOVE POWER & use
test equipment to confirm a circuit is at ground potential BEFORE touching it. NEVER reach into or enter an enclosure to
service or adjust the equipment until the absence of power has been confirmed.
DO NOT SERVICE OR ADJUST ALONE: Under NO circumstances should ANY person reach into or enter the
enclosure for the purpose of servicing or adjusting the equipment except in the presence of someone who is capable
of rendering aid in case of an accident/emergency.
RESUSCITATION: Personnel working with or near high voltage should be familiar with resuscitation methods (CPR
and/or AED). CPR info may be obtained from medical personnel. For AED (Automated External Defibrillator) information,
contact supervisor or hosting administration for details on the availability and/or location of an AED unit at your worksite.
ELECTROSTATIC DISCHARGE PRECAUTION
This equipment contains electrostatic discharge (ESD) sensitive devices. ESD sensitive equipment handling methods
must be used to prevent equipment damage during handling and servicing.
ESSENTIAL HEALTH AND SAFETY REQUIREMENT
Refer to document “P/N 240117—Essential Health and Safety Requirements”.

7580368_Rev D Page 8of 89
I.VII THINGS TO NEVER DO
NEVER touch circuits or reach into an enclosure until the disconnection of power and absence of charge has been
confirmed
NEVER service or adjust equipment alone. Electric shock can lead to cardiac arrest. Presence of immediate aid gives
you a 90% chance of survival, but this drops by 10% with every passing minute. After 5 minutes, resuscitation
without permanent heart and/or brain damage is nearly impossible. Consider this: Without the immediate aid of
CPR or an AED, what are the odds you will be found and successfully revived in under 5 minutes?
NEVER ignore warning symbols or fail to read safety signs
NEVER skip steps in a sequence, unless specifically instructed to do so by the manual, software, and/or authorized
ASC Tech Support Personnel. Aside from risking harm to yourself, you risk doing permanent damage to the equipment
NEVER touch or stand near any potentially moving parts (even if they are not in motion at the time) when the unit is in
operation or powered on, as they may move without warning
NEVER stand underneath any object while it is being lifted
NEVER remove, disable, or exceed the unit’s safety, software, security, or movement limits, unless specifically
instructed to do so by the manual, software, and/or authorized ASC Tech Support Personnel. The careless disabling of
such safeguards is one of the most common causes of serious equipment damage during installation and operation
I.VIII Parts Verification
STOP! READ BEFORE BEGINNING ASSEMBLY OR INSTALLATION!
Upon receipt of your order, the shipment should be verified to ensure that all parts have reached your site. This process
should occur before the installation process begins. ASC Signal Corporation thoroughly inspects and carefully packs all
equipment before shipment. If you find that there are missing or damaged components, please refer to the step-by-step
instructions (located in back of this manual) on how to properly report equipment loss or damage. When you have
received your order, verify that all parts contained in the shipment correspond to the parts listed on your packing
slip/inventory.

1.0 Operation of Handheld Controller
The NGC-ODU may be controlled from the pedestal base, via use of the Handheld Controller (shown below in
Figure 1-1).
Figure 1-1: Handheld Controller with Connection Cable
The Handheld Controller is QTERM-G55 model controller with a 320x240 pixel, LCD transflective FSTN,
grayscale (16 shades) display. The display screen employs a light emitting diode (LED) backlight. The LED
provides excellent readability under most lighting conditions and can operate in either portrait or landscape
mode. The FSTN contrast is software-controlled and compensated for temperature. The transflective display
provides excellent sunlight or high ambient light readability. The backlight also provides white lighting for high
contrast and easy readability. Brightness of the backlight and FSTN contrast are controlled by software. User
input occurs through a rugged 24-key membrane keypad with steel domes. This 24-key keypad allows for
function/soft keys, four-way directional control and alphanumeric data entry. Certain keys can perform alternate
functions when the shift key is enabled (refer to Table below Figure 1-2 for specifics).
Setup parameters are password protected in the handheld terminal and can only be accessed by logging
into the handheld. In most cases, the handheld terminal will be shipped with the Persistent Password
already logged in. If the handheld terminal requests that you login, use one of passwords listed below.
The “Temporary” password will automatically logout when power to the handheld is disconnected. The
“Persistent” password will keep the handheld logged in until the user forces it to logout. You will need the
following passwords to access the system:
ODU/Handheld TEMPORARY Installer Password:JFQB23
ODU/Handheld PERSISTENT Admin Password:32BQFJ
The handheld terminal’s LCD screen is a backlit graphical interface. The LCD displays messages to
indicate the antenna functions and status. Antenna functions and status include whether or not the
antenna is moving, if a satellite signal is found, if a signal is lost, etc. The LCD indicates soft key
functions on a given screen. Additionally, the LCD alerts you if a system fault occurs, and allows you to
troubleshoot the antenna.

7580368_Rev D Page 10 of 89
DO NOT LEAVE HANDHELD SCREEN IN DIRECT SUNLIGHT! Screensaver does not protect screen from
sunlight. Prolonged exposure to sunlight will cause screen to become temporarily washed out, making it unusable
until returned to shade for a time. If exposed for too long, such as an entire day, screen may be permanently damaged.
The screen saver becomes active:
After 10 minutes = screen dims
After 30 minutes = screen saver comes on
After 50 minutes = screen goes dark
To reactivate the dark screen, simply press any key on the handheld.
The user operates the handheld terminal by using soft keys and implemented by pressing function keys. The
handheld terminal has four function keys, labeled F1–F4. When one of these four keys has a specific function,
the function for that key is displayed above it on the LCD. If a key does not have a function for the current
screen, field, and/or mode, then the space above it on the LCD will remain blank.
Operational configuration is used to indicate the basic system setup of the NGC-ODU. It usually matches the
role the antenna system plays. It is primarily a setting about what kinds of equipment are expected to be
present in the system.
Fixed antenna is a system whose geographic location is not normally assumed to change. The location
is generally entered by hand using the handheld or the NGC-IDU. In this configuration, the system will
use the attitude sensor if it has access to it, but does not require it to be present for normal operation. A
fixed antenna may also include an SRT (this is called a ‘combined system’) but of course does not
require it.
Mobile antenna paused is a system with a changing location, including frequent relocations, but is
normally used on the pause, and which includes as AS-1, which is equipment to ascertain the geographic
location of the system as a regular part of operation. This operational configuration enables certain extra
functions designed to assist in operation.
SRT-only is a system with a main reflector that is not motorized and cannot move, but has an SRT
installed
SRT Slave Only is reserved for future applications
Other settings are reserved for future applications.
LocalRemote indicates which entity has control of the system (can move the antenna, change parameters).
Other modes are as follows:
Local means the system is under control of the IDU front panel or the IDU remote front panel software
Remote means the system is under control of the SNMP Agent
Local handheld means the system is under control of the handheld terminal
1.1 Handheld-to-ODU Connection
To connect Handheld Controller to the NGC-ODU:
1. Remove the tethered plug, normally plugged into J3 (on the underside of the ODU cabinet)
NOTE: Removing tethered plug from J3 will lock out all control (the same as pressing an ESTOP button), prohibiting
antenna movement until either Handheld cable is plugged in J3 or tethered plug is returned to J3.
2. Plug the Handheld Controller cable (as shown in Figure 1-1) into J3
3. Handheld Controller should power on automatically, so there is no need to press the power button
To ENGAGE an ESTOP:
Press in any red ESTOP button
Depending on the options for your particular system/equipment, ESTOP buttons can be present in any
number of locations, such as on the ODU, IDU, Handheld Controller, or mounted on nearby walls (or other
structures)
NOTE: Engaging any ESTOP button will lock out all movement/control for antenna. (Also locks out movement/control
from IDU)
To RELEASE an ESTOP:
Handheld & IDU ESTOP buttons are released by turning ESTOP knob Clockwise until it pops out
ESTOP on side of ODU (or at optional ESTOP stations) can be released by pulling out the button

2. Jog [Main Dish] SCREEN
The JOG SCREEN (see Figure 1-5 and related table) is used to move the antenna. This screen can be
used to jog any axis, as well as to see angle feedback from the encoders or resolvers, and to view any
faults or alarm conditions. The JOG screen can also be used to change the Jog speed (10%-90%) for the
Az and El axes using the number pad.
Path: HOME SCREEN -> F1 (JOG)

3. GoTo SCREEN
The GoTo SCREEN (Figure 1-6), same as the JOG SCREEN, may also be used to move the antenna.
However, this screen is more precise and less labor intensive than the JOG SCREEN. With the GoTo
SCREEN, the user can edit the Az, El, and/or Pol fields, as well as command/execute antenna movement
with the GoTo AZ, EL, POL soft-key (F4).

4. Parameters SCREENS & PAGES
The Handheld controller has dozens of screens which allow the advanced user to view almost all of the
NGC-ODU’s configuration parameters. The basic user, however, is authorized to view only a handful of
these parameters.
This section provides you with some representative examples. The DETAILED STATUS screens (Figures
1-7a & 1-7b) display lists of parameters that are associated with attitude, site location, current location,
operational configuration, and any faults/alarms associated with said parameters. See Appendix C (Table
C.1) for all parameter field descriptions.
