Angle Monitor Commands
The following commands are available in the angle monitor:

Use the following commands to set up drive levels, or to start an the internal servo, for both the azimuth and the elevation axes. The range of -100 ... +100 represent the digital value that is applied to the output D/A converters.
| Command | Value | Purpose |
|---|---|---|
| ad or ed | Number in the range of -100 ... +100 | Output a given motor drive. |
| ap or ep | Angle in degrees (°) | Move the antenna to a fixed position. |
The host computer serial interface continues to control RCP8 until you type a command that moves the antenna on the TTY screen. RCP8 remains under the terminal's control until you exit the local monitor mode.
| The terminal may be used as a monitor however, do not input commands that can seize control from the host computer. |
If commands are used to move the antenna, checks are usually performed that restrict the antenna's travel to ensure the soft limits (lower and upper) are not exceeded. The checks are done by executing the position servo silently in the background using the 2 soft limits as target points. If the present motor drive does not rest in between the calculated drives, the drive is automatically overridden by either one of those values. This safety measure prevents the antenna from running into its stops.
