B.) RS-422 Connector: The RS-422 (RJ-11) connector allows the PTC80 to communi-
cate to a Graflex pan & tilt head using the serial balanced RS-422 communications stan-
dard. The connections are described below:
Pin 1: Data to the PTC 80 from the pan & tilt head -
Pin 2: Data to the PTC 80 from the pan & tilt head +
Pin 3: Data from the PTC 80 to the pan & tilt head -
Pin 4: Data from the PTC 80 to the pan & tilt head +
RS-422
C.) Power Connector: The power (DC jack) connector pro-
vides power to the PTC80. The connections are described be-
low:
Center Pin: Ground
Outer Shield: +12 VDC
DC Jack
D.) Power Switch: The power switch turns the +12VDC input power ON (1) or OFF
(O). The switch is shown below:
Power Switch
2.3 Power Up
After all connections have been made and verified, the power switch may be placed in
the ON position. The front panel red LEDs should sequence from all off to all on and
then back to all off.
The front panel Green LED will remain ON and the unit is ready to use.

3.1 Front Panel
The front Panel of the PTC80 Controller is shown below in Figure 3.1. Each of the con-
trol groups is identified with a letter and explained in the following paragraphs.
3.0 Operation
Figure 3.1
A
B
C
A.) Joystick: The joystick, shown in Figure 3.1A, provides a
proportional speed control over pan & tilt. The further the
joystick is deflected, the faster the pan & tilt head will move.
Both axes may be moved simultaneously.
The speed of the joystick is further controlled by the Speed
range potentiometer item B. As the Speed Range potentiome-
ter is increased, rotated clockwise, the maximum speed of the
joystick is increased. Conversely, as the Speed Range Poten-
tiometer is rotated counter-clockwise, the maximum speed of
the joystick is decreased.

C.) Presets: There are two sets of preset switches which work together to provide the abil-
ity to program and recall up to 10 presets. The Preset Switch group shown in Figure 3.1C
and the PRG/PAGE switch group shown in Figure 3.1D are used to operate the preset
functions.
To program a preset, position the pan and tilt head to the desired pan and tilt positions and
depress the PRG switch. The PRG LED will then be illuminated and stay illuminated until
either a preset switch is depressed or the PRG switch is again de-
pressed.
To complete the programming of preset 1-5,
simply depress the preset switch 1, 2, 3, 4 or 5.
The selected preset LED will become illumi-
nated and the PRG LED will be extinguished.
To Program presets 6-10, once again depress the
PRG switch but this time also depress the PAGE
switch. Both the PRG and PAGE LEDs will become illuminated. As
before, complete the programming by selecting a preset switch (1
through 5)and depress the switch. The PRG LED will be extin-
guished but the PAGE LED and the selected Preset LED will remain
illuminated.
To recall preset 1 through 5, make sure the PRG and PAGE LEDs are
not illuminated and depress the desired preset switch. The pan and tilt
head will then return to the pan and tilt positions programmed for this preset. To recall pre-
set 6 through 10, make sure the PRG LED is not illuminated but the PAGE LED is illumi-
nated. Depress the desired preset switch and the pan and tilt head will then return to the
pan and tilt positions programmed for this preset
B.) Speed Range Potentiometer: As described in the joystick discussion,
the Speed Range potentiometer, shown in Figure 3.1B, controls maxi-
mum speed of the joystick.
During a preset move, the Speed Range potentiometer controls how fast
the pan & tilt head will move between presets. Again, the further the
potentiometer is rotated clockwise, the faster the preset motion.

There are several functions which may be selected by using the preset switches in combi-
nations described below. Figure 3.2 shows a label located on the bottom of the chassis.
The label is a description of these functions .
3.2 Special Functions
To activate any of these functions, both the PRG and the PAGE switches must be simulta-
neously depressed and held down.
A.) Depress and release Preset Switch 1 and then release the PRG and PAGE switches.
The pan & tilt head will begin a continuous preset 1 to 5 sequence and continuously
repeat the sequence until another control is activated.
B.) Depress and release Preset Switch 2 and then release the PRG and PAGE switches.
The pan & tilt head will begin a continuous preset 6 to 10 sequence and continuously
repeat the sequence until another control is activated.
C) Not Used
D.) Depress and release Preset Switch 4 and then release the PRG and PAGE switches.
The azimuth position encoders will be zeroed.
E.) Depress and release Preset Switch 5 and then release the PRG and PAGE switches.
The elevation position encoders will be zeroed.

There are several functions which may be selected by using the switches located on the PCB
(Printed Circuit Board) inside of the PTC80 Controller. Figure 3.3A illustrates the PCB in-
side the chassis and Figure 3.3B is shows the actual switches. Figure 3.3 C shows the label
attached to the inside bottom of the chassis describing the function of each switch.
3.3 PCB Functions
The switches are numbered 1 through 6 and may either be ON (0) or OFF (1). The list-
ing below describes the function of each switch.
Switch #1: Not Used
Switch #2: Not Used. The label says to but in the ON (0) position but this has no effect.
The PTC80 Controller transmits in both RS-232 and RS-422 communications for
mats simultaneously. Simply connect to the one desired and ignore the other.
Switch #3: ON (0) reverses the pan direction of the joystick
Switch #4: ON ((0) reverses the tilt direction of the joystick. This is sometimes used by
people who want the joystick to operate like an aircraft stick.
Switch #5 and Switch #6 work together to select the proper BAUD Rate.
Make sure that Switch #5 is ON (0) and Switch #6 is OFF (0). This setting is for
38400 BAUD which is the BAUD rate used by all Graflex pan and tilt heads. Set
ting Switch #5 and Switch #6 to any other positions will prevent the PTC80 from
communicating with the pan and tilt head.
