American Dynamics ad1641m-2 Operating Guide
FEATURES
Pan/Tilt and Lens Control
As shipped, the 1641 Receiver provides drive outputs at 24
VAC for control of Pan/Tilt motors and 10 VDC output for
lens control. The lens output voltage can be varied from 7 to
12 VDC with a potentiometer located on the side of the unit.
A 12-pin connector on the side of the unit contains all the
connections required for control of the Pan/Tilt and lens.

Note: Certain Pan/Tilt units require alternate voltages other
than those noted in this manual. If necessary, call the

Auxiliaries
Two form “C” relays are provided for auxiliary use, either for
latching or momentary operation control. The relay contacts
are for use with an external power source not exceeding
24VAC or 30VDC, and a load current not exceeding 1 Amp.
See Receiver Configuration Setup, page 4, to configure these
relays for latching or momentary operation.

Auto Sense
The 1641 has automatic sensing of pan/tilt and lens servo
voltage direction at initial power up when preset scenes are
enabled. This feature determines the polarity of the connected
reference voltages in order to determine proper motor direction
control. (See page 14, Power-up Auto Sense.)

control. (See page 14, Power-up Auto Sense.)
Preset Scene
The Preset Scene feature allows the operator to select and store
in the Receiver memory a specific camera scene, and to recall
that scene at a later time via keyboard commands. Preselection
of a scene is available only for Pan/Tilt and Lens units with
feedback potentiometers. The pre-selected scenes, also known
as a Programmed Scene, are saved in non-volatile memory for
protection in the event of a power failure.

When controlled by a Matrix Switching System, the 1641
Series Receiver can be programmed for 71 preset scenes for
that camera. (Note: This differs from the American Dynamics'
standard of 72 presets per camera.) Refer to the installation
and operation manuals for the particular Matrix Switching
System for programming procedures. Note that the setting of
position 1 and 2 on DIP Switch S7 (See SETUP, page 4,
determines if preset scenes are enabled for the unit. All units
are shipped from the factory with preset scenes enabled.

panning using Presets or Automatic panning using an
auxiliary.

Automatic Panning using Presets
The 1641 Series Receiver is capable of automatic panning
using preset end stops for a Pan/Tilt unit with preset capability.
When initiated by the operator, the automatic camera panning
will operate either continuously or for a 30 minute period,
depending on the Setup option chosen (see DIP Switch S7,
position 6, page 4).

Automatic Panning using an Auxiliary
The 1641 Series Receiver is capable of automatic panning
using an auxiliary relay (Aux 1) for a suitably equipped
Pan/Tilt unit which has internal Autopan capability. The
internal autopan control is provided by changing the Receiver
auxiliary 1 relay from a unpowered relay to a powered relay
with 24 VAC on it (see Setup, Autopan using Auxiliary 1,
page 5).
