(disabled) then the other two items will not appear in the list of CONFIG mode items. In the descriptions
which follow the controlling items and the items, which are controlled by other items will be clearly
delineated.

4.10.1 AutoPol

The AutoPol system allows the controller's polarization control function to be slaved to the level of a
digital input derived from a satellite receiver. Please refer to sections 2.5 and 3.8 for more information
on the AutoPol system.

The AutoPol system is disabled and enabled via the AutoPol Enable CONFIG mode item.

AUTOPOL ENABLE:0 CONFIG
0-DISABLE, 1-ENABLE ENT,BKSP,SCRLL ^v

The AutoPol Vpol Level CONFIG mode item specifies the polarity of the AutoPol digital input signal. A
value of zero implies that a low on the AutoPol digital input specifies vertical polarization and a value of
one implies that a high level on the AutoPol input selects vertical polarization. Access to this item is
only allowed when the Expert Access Flag is set.

AUTOPOL VPOL LEVEL:1 CONFIG
0-LOW, 1-HIGH ENT,BKSP,SCRLL ^v

4.10.2 Simultaneous Azimuth and Elevation Movement

The Simultaneous Az/El Enable CONFIG mode item is used to enable simultaneous azimuth and
elevation movement when moving to a satellite selected via SETUP mode.

SIMULTANEOUS AZ/EL ENABLE:0 CONFIG
0-DISABLE, 1-ENABLE ENT,BKSP,SCRLL ^v

NOTE: If the total current draw from both motors exceeds 8 amps, it is not possible to utilize this
feature. Trying to enable it in this case will cause a breaker to open, which will disable the drive and
generate an antenna jammed error.

4.10.3 Remote Communication Parameters

The following items are used to enable and configure the remote RS-422 communications capability.
Access to these parameters is allowed only when the Expert Access Flag is set. The Remote Mode
Enable
item is the controlling item for the Comm Port Address and Comm Baud Rate items.

The Remote Mode Enable item is used to enable access to REMOTE mode. If this item is enabled,
REMOTE mode will activate whenever a valid command is received via the serial port or in response to
MODE key manipulations.

REMOTE MODE ENABLE:0 CONFIG
0-DISABLE, 1-ENABLE ENT,BKSP,SCRLL ^v

The Comm Port Address item selects the address of the communications port. See the Appendix
covering the communications protocol. Valid values for this parameter are 49 to 111.

COMM PORT ADDRESS: 50 CONFIG
49 - 111 ENT,BKSP,SCRLL ^v

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).
