4.5 Auxiliary Operation (S101, #1–4)
An auxiliary function is one that can be turned on and
off by a remote receiver. It is in addition to the four
pan/tilt functions and three lens control functions.
They may be used for any purpose such as auto-pan or
lighting control.
Each receiver/driver has four auxiliary outputs. Note
that auxiliary 1 can be associated with the auto-pan
function and is wired through the pan/tilt connector.
Each auxiliary may be the latch or momentary type.
Latch means the auxiliary can be turned on and will
stay on until it is turned off. Momentary means the
function will be on as long as the enter key of the
keyboard is pressed.
To select whether an auxiliary is latch or momentary:
1. Locate the two 4-position DIP switches on
the top of the printed circuit board.

2. Each switch is numbered 1 to 4 and
corresponds to the auxiliaries 1 to 4.
3. To make an auxiliary momentary, push the
switch of the desired auxiliary to the OFF
direction.
4. To make an auxiliary latching, push the switch
of the desired auxiliary to the ON direction.
These switches may be easily changed at any time or
may be set prior to installation.

4.6 Lens Polarity (S102, #2)

To accommodate different manufacturers of motorized
lenses, the receiver/driver lens driver polarity can be
reversed. This provides the capability to coordinate all
zoom lenses so that each moves in the same direction
as long as the same control position is activated by
system operators. The following table shows the lens
voltage polarity for ON and OFF positions of S102, #2.

Zoom In – Volts
Zoom Out + Volts
Focus Far + Volts
Focus Near – Volts
Iris Open – Volts
Iris Close + Volts
Using the data that accompanies the lens used at this
camera location, determine which selection accepts the
lens and set the switch accordingly.

4.7 Auto-/Random-pan (S102, #3)

The auto-pan feature provides automatic and
continuous panning between limit switches. The
random-pan feature is similar to auto-pan in that it
provides automatic panning between limit switches.
With random-pan, the panning motion is turned on
and off at random intervals and the direction of
motion is random. Since random-pan provides a duty
cycle of not more than 50%, it is the recommended
mode when using a pan/tilt which is not rated for
100% duty cycle operation.
The assignment of auto-pan and random-pan may be
changed using switch #3 of S102 when software
control auto-pan type is selected. See Auto-pan (S102,
#4). With the switch in the OFF position, auto-pan is
