The COMM BAUD RATE item selects the baud rate that the controller’s serial port will be initialized to.

Valid values for this parameter are 3 (300 baud), 6 (600 baud), 12 (1200 baud), 24 (2400 baud), 48 (4800

baud) and 96 (9600 baud).

5.8.4 Position Display Offsets

AZIM DISPLAY OFFSET: 45.5 CONFIG

-179.99 TO 180.00 ENT,BKSP,SCRLL ^v

ELEV DISPLAY OFFSET: -13.5 CONFIG

-179.99 TO 180.00 ENT,BKSP,SCRLL ^v

POL DISPLAY OFFSET: 2.5 CONFIG

-179.99 TO 180.00 ENT,BKSP,SCRLL ^v

The values specified for the AZIM DISPLAY OFFSET, ELEV DISPLAY OFFSET, and POL DISPLAY

OFFSET CONFIG mode items are added to the position values sensed by the azimuth, elevation, and

polarization position sensors, respectively. These CONFIG mode items can be used to convert the

antenna’s sensed positions into actual pointing angle.

Note that the resolvers must be installed such that the sensed position does not wrap around (from 0.00

to 360.00 or 360.00 to 0.00) within the antenna’s normal range of movement for a given installation. The

controller’s Azim Display Offset, Elev Display Offset, and Pol Display Offset CONFIG mode items can be

used to correct for any position offsets introduced by this requirement.

5.8.5 Polarization Equipment Code

The RC2500 can support a polarization control device. The user can specify that either no polarization

control device is present (as for circular polarization), a single port polarization control device is present,

or a dual port polarization control device is present. The POL CONTROL EQUIPMENT Code CONFIG

mode item specifies the type of polarization control present for a given installation.

POL CONTROL EQUIPMENT CODE:1 CONFIG

0-NONE,1-1PORT,2-2PORT ENT,BKSP,SCRLL ^v

5.8.6 Azimuth, Elevation, and Polarization Drive Options

The CONFIG mode items described in this section set the antenna movement parameters. Access to the

CONFIG mode items described in this section is permitted only when the Expert Access flag is set.

The AZ/EL/POL DRIVE OPTIONS ENABLE CONFIG mode item is the controlling item for the other

CONFIG mode items described in this chapter. When this item is disabled, the user does not have

access (via CONFIG mode) to the other items described in this section. Note that when this item is

disabled, the current values of the other items described in this section are used to control azimuth and

elevation movement. In other words, disabling this item does not reset the other items described in this

section to their default values.

AZ/EL/POL DRIVE OPTIONS:0 CONFIG

0-DISABLE, 1-ENABLE ENT,BKSP,SCRLL ^v
