Electronics Guide
XSTOP
Stop the hex sequencer. Return all servos to normal operation.
1. When a horizontal servo is moving, its speed will be adjusted based on the Front/Rear
pulse widths, the XL/XR percentage, and the XS percentage. Regardless of the travel
distance from front to rear (adjusted by XL/XR), the total move time will be the HT
divided by the XS percentage.
2. When a vertical servo is moving from Low to Mid or from Mid to Low, it will move at the
speed specified by the VS command. When a vertical servo is moving from Mid to High
or High to Mid, the vertical speed will be adjusted so that the horizontal and vertical
movements end at the same time.
3. Any of the Hex Sequencer commands can be issued while the sequencer is operating.
They will take effect immediately.
Hex Sequencer Examples:
"LH1000 LM1400 LL1800 RH2000 RM1600 RL1200 VS3000 <cr>"
Sets the vertical servo parameters.
"LF1700 LR1300 RF1300 RR1700 HT1500 <cr>"
Sets the horizontal servo parameters.
"XL50 XR100 XS100 <cr>"
Causes the gradual left turn at 100% speed (and starts the sequencer if it is not already
started).
"XL -100 XR 100 XS 50 <cr>"
Causes a left rotate in place at 50% speed.
"XSTOP <cr>"
Stops the sequencer and allows servo channels 0-5, 16-21 to be controlled using the normal
servo commands.
Query Hex Sequencer State.
XQ <cr>
Returns 1 digit representing the state of the hex sequencer, and the approximate percentage of
movement in the state. The high nibble will be '0' to '7', and the low nibble will be '0' to '9'. For
example, if the sequencer is 80% of the way through state 5, it will return the value 58 (hex).
