If the voltage varies outside of the operating voltage margins, a
message will be displayed warning the operator the voltage is low or
high.
If the voltage goes beyond the maximum or below the minimum safe
operating voltage, the system will fault and stop motor movement,
halting operations with the error message; “Halting / Hi Volts” or
“Halting / LowVolts” To clear the condition, adjust the DC power to
within the above specification and power cycle the system.
The Rotor Unit will monitor its operating temperature, reporting the
data to the Hand Controller. If the operating temperature reaches 65
degrees C (149 degrees F) a warning message is displayed. If the
temperature reaches 70 degrees C (158 degrees F) and above the
system will stop operating, requiring a power cycle to restart normal
operations. This is designed to protect the electronics when
operating in extremely hot environments.
Remote Control
The Az/El Rotor Controller primary use mode is to be attached to a
computer system using the USB Type-B jack found on the front of the
Controller. The controller supports the Yaesu
1
GS232A Rotator
Control Protocol. Default serial parameters supported are: 9600
baud, 1 Start, 1 Stop, No Parity, No Handshake.
To enter the Remote Control mode of operation, with the controller
on, press and hold both the CW and CCW buttons. The display will
show the following message:
The ‘Antenna Jam’ Red LED will flash each time the controller
receives and responds to a command from the host computer.
While in the Remote Control Mode, manual control of Az/El
movement along with all other user operations are disabled. You
must exit the Remote Control Mode to make any manual azimuth or
elevation changes; do not force by hand any antenna position
changes.

19,200 baud. Press the button that corresponds to the desired baud
rate. The new baud rate will be displayed for a few seconds then the
controller enters its previous operating mode. The new value is
saved in flash memory and is persistent over power cycles.
Setting
your Call Sign / Vanity Text
The 12PRSAT Rotor Controller allows you to set and will display
during idle time where the controller is not turning the antenna, 8
Characters of your choice on the top line of the display. This can be
your call sign, antenna information, or any other message you want
displayed. This information can be changed as often as you like.
The process of setting the text message is similar to setting the initial
antenna heading. Turn on the controller and when the “Portable
Rotation” message is displayed, hold down the CCW button [left
Button]. Continue holding the button until the “Ent Call” message is
displayed, then Release the button. The bottom line will now display
the current message text and the first character position will show
that it is ready for input as it will be underlined. Use the CCW and
CW buttons to go forward or backward through the Letters and
Numbers, pressing the MODE button after the correct character is
selected. You must do this operation for all 8 character positions. If
no change is needed, just press the MODE button to move to the
next character.
