RC4000 ACU Boardset
3.3.1.2 INSTALLATION ACCESS ITEMS
This set of configuration groups allows the user to modify parameters that are most typically changed for
a particular installation.
3.3.1.2.1 System Definition
MODE:2
GPS:3
COMP:2
<1-LOCATE 2-MENU 3-MANUAL 4-VSAT 5-POS>
The CONFIG-SYSTEM screen allows the user to indicate the existence of optional equipment. Indicating
that the item is not present will keep the controller from waiting for a valid response from the item in
various modes. For example, if the GPS receiver is not present, the RC4000 will simply report "NO GPS
PRESENT" vs. waiting for a period of time to decide that it is not receiving data from the GPS.
MODE:
INITIAL MODE <1-LOCATE 2-MENU 3-MANUAL 4-VSAT 5-POS>
This item specifies to which of the modes listed the RC4000 will go to upon power up.
Selections 1, 2, 3 or 5 will direct the RC4000 to go to LOCATE, MENU, MANUAL or POSITION mode
upon power up. For example, if the controller does not have the GPS and compass options, the user
may want to power on to the POSITION mode.
Selection 4 puts the controller in "VSAT" mode described in
thoroughly reviewed prior to placing the controller into "VSAT" mode.
ANT_SIZE:
ANTENNA SIZE <1-9999 CM>
This item specifies the size of the reflector in centimeters. For example, a 5.9 ft. diameter reflector (1.8m)
would require a value of 180 (cm.) be specified.
The antenna_size_cm is used by inclined orbit tracking algorithms to characterize the antenna's
beamwidth thus affecting timing of various tracking movements. The value is also used by autopeak
algorithms to determine the size of autopeak step movements.
GPS :
<0>NONE <1>TRUCK <2>TOP <3>BACK
This item specifies whether or not the optional GPS receiver is present and how the GPS is mounted if it
is present. If specified as not present (0), the "NO GPS PRESENT" message will be displayed in various
RC4000 screens. If the GPS option was not purchased, this field will always remain at 0. If the GPS is
specified as "TOP" or "BACK" (referring to an antenna mounted GPS), the RC4000 will require that the
dish be moved to the DEPLOY position to obtain GPS location information.
ANT LOOK:
ANT LOOK REFERENCE <1>HIGH <0>LOW
The elevation_lat_configuration item is used for mount types that have different feed boom configurations
to achieve different elevation pointing angles. The reported elevation angle will be offset by different
values according to whether the high or low elevation configuration is specified. Other elevation related
items such as stow and deploy positions will also be affected. NOTE: for mounts that have only one
feed boom configuration, this configuration item may be set to either value with no consequence.
DRIVE:
DRIVE OPTION <0-SINGLE 1-AE 2-AP 3-AEP>
This item determines the status of multi-axis motion. For example, setting this item to 1 will have both the
Azimuth and Elevation axes operating simultaneously. Some systems with particularly heavy current
requirements may only operate successfully one axis at a time.
