Installation and Wiring
This section covers the steps necessary to connect and operate a PT10-ADD Additional Camera
Pan/Tilt System. Before continuing, verify that you have received the correct components for your
package. Refer to the PT10-ADD System Components section on page 1 for more information.
Preparing the AXB-PT10 for Communication
When you add one or more AXB-PT10s to your system, it will be necessary to set the AXlink
Device DIP switches on the additional PT10s. The AXB-PT10 that came with your kit was factory
set as AXlink device number 90. The first additional AXB-PT10 must have its AXlink device value
incremented by a value of 1, up to 95 (for a maximum total of six PT10s).
The AXlink Device DIP switch is located beneath the round cover on the back of the AXB-PT10.
FIG. 2 shows the location of the DIP switch and each of the possible AXlink Device DIP switch
settings for additional AXB-PT10s.
Mounting the AXB-PT10
Mount the AXB-PT10 to a flat horizontal surface, either upright or inverted.
1. Select a surface that can support the combined weight of the AXB-PT10 (8.00 lbs./3.63 kg),
camera/lens (10 lbs./4.54 kg), and control cables. Some support surfaces include the
WM-CAM, PM-CAM, and TM-CAM mounts available for use with these units.
2. Locate the external white position markers located on the pan and tilt axis. The position
markers must align with the pan and tilt axis in order to be considered in the home position.
FIG. 3 shows the camera cradle attachment in the center position.
3. Mount the PosiTrack unit to a flat surface by drilling four holes, according to the mounting-
plate dimensions shown in FIG. 4. Secure the unit to the surface using four 1/4" x 20 machine

Wiring Information for the AXB-PT10
Each PosiTrack Controller has an RS-232 DB-9 connector, lens control DB-15 high-density
connector, and an AXlink 4-pin connector. Always provide enough cable to accommodate the
desired range of motion for the PosiTrack unit and its camera/lens. The Lens Power switch on the
control panel (FIG. 10), removes any power noise on the incoming video by turning power On/Off
to Pin 1 of the DB-15 lens control connector when the camera/lens is powered from a separate
supply.
The AXB-PT10 receives all power through the +12 VDC and GND connections on the 4-pin
AXlink connector. The portion of the power directed toward the pan and tilt motors is fused. The
fuses are self-resetting.
The AXB-PT10 power rating is 2 amps @ 12 VDC. Refer to FIG. 11 for details.

Wiring Guidelines
The PosiTrack Controller requires local +12 VDC power (optional) to operate properly. The
maximum wiring distance between the power supply and the PosiTrack Controller is determined by
power consumption, supplied voltage, and the wire gauge used for the cable. The following table
lists wire sizes and the maximum lengths allowable between the PT10 and the power supply. The
maximum wiring lengths are based on a minimum of 13.5 VDC, available at the power supply.
The PosiTrack Controller is powered from an optional local power supply. The wiring distances
listed for the AXB-PT10 in the above table are based on a +12 VDC power supply and are capable
of 2 amps (continuous) with a maximum current of 20 amps. The PosiTrack unit provides power
outputs for the camera/lens combination.
Using the AXlink connector for data and power
To use the AXlink 4-pin connector for data communication with the AXB-EM232 and power
transfer from the PSN6.5 power supply, the incoming PWR and GND cable from the PSN6.5 must
be connected to the AXlink cable connector going to the AXB-PT10. FIG. 11 shows how the power
cable from the PSN6.5 is used to power the AXB-PT10. This same figure shows how the GND
cable is connected onto the existing GND cable on the AXlink cable coming from the AXB-
EM232. Always use a local power supply to power the AXB-PT10. This is the configuration of the
supplied CC-AXL AXlink Connection Cable.

Suggested Wire Types For Custom Cables
AXlink is a control network that uses four wires to carry data and power to all remote devices in the
system. Two wires carry a balanced-line data signal; the other two provide ground and +12 VDC
power. Large distributed systems that use long AXlink runs with a maximum of 3,000 feet
(914.4 m) should use low-capacitance (12-14 pF/ft) shielded twisted pair cable.
! The length of an AXlink wire run is equal to the total length of wire used; a star run made
of one 300' section and six 50' sections equals one 600' AXlink line.
! AXlink data lines (AXM and AXP) are designed for balance-line operation; wire the data
lines in the same twisted pair.
! Use a shielded cable for best results, both to reduce electronic interference radiated by
adjacent wiring and to eliminate noise from AXlink cabling to adjacent audio cabling.
If you find that the included 100' (30.48 m) AXlink cables are not long enough for your application,
use the wire types suggested below to make custom cables.
AXlink - (local-area, low-power requirement)
22/24 AWG 4-conductor cables can be used for short wiring runs.
! Level 3, 4, or 5 unshielded, twisted pair
! Belden 8102, 2 twisted pair, 1 shield 12 pF/ft, PVC and plenum cable available.
