 TABLE 1. CONTROL INPUTS AND FUNCTIONS
 FOR TM2000 P.G.
 ON-BOARD SPEED POTSWith the S3 input high (+5VDC) or open, the pulse generator is set up to use the four on-board speed pots.  With the S1 input high (+5VDC) or open, BASE speed is selected.  When
this input is pulled low ( 0VDC), MAX speed is selected.  The S2 input allows switching fromone set of BASE and MAX speeds to the other set of BASE and MAX speeds.  When this
input is high (+5VDC) or open, BASE1 and MAX1 are selected.  When this input is low
(0VDC), BASE2 and MAX2 are selected.
There are three basic modes of operation when using the on-board speed pots.  One mode
requires the use of the STOP/RUN input and the S1 input.  Normally in this mode both inputs
are high before running.  To start running, the STOP/RUN input is first pulled low (0VDC);
the pulse generator starts running at BASE speed.  The S1 line is pulled low (0VDC) some
time after; this causes the pulse generator to ramp up to MAX speed and continue runningat MAX speed.  If the S1 input is set high (+5VDC) again, the pulse generator will ramp down
to BASE speed and continue running until the STOP/RUN input is set high again.
The second mode of operation requires the use of only one input -- the RDS (Run-Down-Stop) input.  S1 must be high when using the RDS input.  When this input is pulled low
(0VDC), the pulse generator to starts running at BASE speed and immediately  ramps up to
MAX speed.  As long as this input is held low, the pulse generator will continue to run at
MAX speed.  When this input is set high (+5VDC), the pulse generator will ramp down to
BASE speed and then stop.

To operate in this mode, the STOP/RUN input and the S1 input are tied together.Refer to the Table 1 for proper control input settings.  This input is similar to the +VCO input

be used to control the direction and speed of the pulses.  When the joystick is in the middle
pot turned to the minimum gain (max clockwise position).  Push the joystick to one of the
ends, and slowly turn R2 counterclockwise (increasing the gain).  The output pulse rate
should keep increasing until pulses stop.  When the pulses stop, this means that the gain
is too high.  So, turn R2 clockwise a little (decreasing the gain) until output pulses appear
again.  Try this again with the joystick in the other direction, and adjust the pot accordingly.
OFF/ONThis input (pin 8 or TB1) is used to stop output pulses regardless of the operation mode.  A
logic 1 inhibits pulses or turns the output OFF.  A logic 0 enables pulses or turns the
output ON.  At times, it may be desirable to turn off output pulses.  Since the VCO and
Joystick inputs start and stop automatically, the OFF/ON input can be used to turn off
output pulses in these modes.  Normally this input will be grounded or at logic 0.
DIRECTION INPUTThe Direction input (pin 5, TB1) is used only with on-board pots, REMOTE POT, and the
+VCO input.  A logic 1 selects clockwise; a logic 0 selects counterclockwise.  This input
is basically sent straight out (buffered) to the drivers Direction Input.  The +/- VCO and
Joystick inputs do not use this input.

through this connector.  The Clock output on this connector may be the undivided Clock(2.56MHz max.) or a divided Clock;  this is selected by jumper JP2 (see Table 3).  The
