assigned to Auxiliary #1 and random-pan is assigned
to Auxiliary #7. With the switch in the ON position,
auto-pan is assigned to Auxiliary #7 and random-pan
is assigned to Auxiliary #1. This allows the LTC 5135
Series Controller/Followers to access the random-pan
function through its Auxiliary #1.
The random-pan function works only when the auto-
pan software control mode of operation is selected.
This is selected by using switch #4 of S102, Auto-pan.
4.8
Auto-pan (S102, #4)
This unit offers two types of auto-pan circuits. With
S102, #4 in the OFF position, this unit turns on and
off voltage to a socket which is at the same voltage as
the pan/tilt head. This mode should be selected for a
pan/tilt which includes a separate hardwire connection
for auto-panning. Operation is controlled using the
AUX 1 command.
With S102, #4 in the ON position, this unit uses a
current sensor and software to continuously pan left
and right. This is the mode which should be selected
for a pan/tilt which does not have a separate hardwire
connection for auto-panning. Operation is still
controlled using the AUX 1 command.
In the current sensing mode, the hardware circuit is
not used for auto-pan. It is automatically reassigned as
AUX 6.
4.9
Pre-position Adjust (S103, #1)
This switch is used to fine tune the pre-position
function to the particular pan/tilt motor being used.
The default position is OFF. If the motor tends to
overshoot the pre-position, this switch can be switched
ON to improve the operation.
4.10 Manual-iris Override (S103, #2)
This switch is used to enable control of zoom lenses
which provide an Auto-iris/Manual-iris Override
feature. For lenses which do not have a Manual-iris
Override feature, this switch should be placed in the
OFF position. In the manual-iris override mode,
Auxiliary #3 operates as a circuit switch between the
special ground wire of the zoom lens and the lens
motor common terminal (see lens data sheet for
pinout/connection information). When the switch is
ON, Auxiliary #3 is automatically activated and
latched when the IRIS control on the system keyboard
is used. This action then switches the lens between
normal auto-iris mode and manual-iris override mode.
Manually turning Auxiliary #3 to its OFF position
returns the lens to its normal auto-iris mode.
4.11 RS-232 Baud Rate (S103, #4)
This switch is used to select the baud rate of the
RS-232 port. The OFF position selects 4800 baud
while the ON position selects 9600 baud.
4.12 AutoSpeed (S104, #1)
AutoSpeed provides variable lens speed operation. The
lens speed starts slow and increases as the lens control
is held on. The speed resets to slow when the lens
control is released.
4.13 Lens Speed (S104, #2 & #3)
The lens speed switches provide for a fixed lens speed,
slow or fast. The lens speed can be set by referring to
the Lens Speed Table.
4.14 Lens Voltage (S104, #4)
This setting allows the use of lenses with a nominal
voltage of either 6 volts or 12 volts. Set this switch OFF
for 6 volt lens types and ON for 12 volt lens types.
4.15 Site Address
The control signal, which is distributed to the
receiver/driver, is common to all such devices. The
code contains an address for each instruction. Several
devices can be connected to the same code wire,
making installation and modification simple. Each
remote device on the common signal must be set with
a unique address.
Follow this procedure to set the site address:
1. Locate the four digit thumbwheel switch on the
top of the receiver/driver printed circuit board.
2. Dial the number of the camera at this site. This
number should match the camera number that
you select from the keyboard.
