Introduction

Lens Control Modes

The Servomotor and Motor modes are two Analog Voltage Control methods available on the

PosiTrack units.

Servomotor Mode

This method is generally used in broadcast or videoconference-style lenses. The voltage range used for servomotor style lenses is +2.5 to +7.5 VDC. These lenses can be controlled in two different modes: positional mode and speed mode.

! Positional mode is the most common Servomotor mode. When voltage changes, the lens moves and remains still until the voltage changes. For example, if a lens receives a voltage of +3 VDC, the lens moves to the corresponding position and stays there as long as the voltage remains at +3 VDC. The movement speed of the lens motor is a function of the PosiTrack unit’s analog output. The lens servomotor receives the preset voltage when a preset is recalled in the positional mode.

! Speed mode moves the lens when the voltage deviates from the center point of its range.

The farther the voltage moves away from the center point of reference, the faster the lens motor moves. The lens must have POT outputs when recalling a preset in this mode,. The outputs pass to the PosiTrack unit, and when the received voltage level matches the level stored in the preset, the voltage returns to zero. Servomotor mode lenses not having POT outputs do not have preset recall capability.

Motor Mode

Motor mode is used when the lens requires the motors be directly driven from an external source.

The standard voltage ranges are

± 6 VDC or ± 12 VDC with a center (no motion) of 0 VDC. Unlike servomotor lenses, these only operate in speed mode.

The lens moves in relation to the voltage offset from zero. The farther the voltage moves away from the center point, the faster the lens motor moves. The lens must have POT outputs when recalling a preset in this mode, these outputs are then passed to the PosiTrack unit. When the received voltage level matches the level stored in the preset, the voltage returns to zero. Motor mode lenses not having POT outputs do not have preset recall capability.

Pan and Tilt Control

Presets and travel limit stops are based on encoder counts from a home position index, located at the center of each axis’ range of motion. The SETUP button, on the rear of the unit, allows you to run a series of pre-set movements designed to test a sample of the PosiTrack unit‘s field of motion.

The system does 10-degree tests of motion for both directions of pan and tilt, and then returns to its

center position. Refer to Configuration Settings section on page 5 for more information on the

SETUP button.

AXB-PT10/30 PosiTrack Camera Controllers 3

Introduction

Zoom, Focus, and Iris Control

Each PosiTrack unit delivers a low voltage pulse-width-modulated output for zoom, focus, and iris functions for motor mode lenses. These units are also capable of receiving reference voltage rails and sending zoom, focus, and iris control signals in response to these rails. In this setting (slideswitch configured), no active control signals will reach the lens before power (+ 12 VDC and

GND) is supplied to the lens. This motor mode applies to the control of the Fujinon and Canon teleconferencing lenses. During preset recall operation, these outputs are synchronized with the pan

and tilt motions. Refer to the PosiTrack Unit Lens Compatibility table on page 1. Four solid state

relays are also provided to control the zoom, focus, and iris speed/position mode selection and iris local/auto selection on the Fujinon MD series and Canon KTSA series lenses.

Pre-Installation


There are four SPDT slide switches in the lens control section (FIG. 3). Three of the switches toggle the lens control selection between servomotor or motor mode hardware for control of zoom, focus, and iris. The fourth selects between ± 6 VDC and ± 12 VDC control for motor mode lens functions.

An SPDT switch is a Single Pole-Double Throw switch. This switch is completed at both positions. An example is the Volt switch that is active in both the 6 and 12 positions.

Each PosiTrack unit consists of two main Printed Circuit Boards (PCBs):

! PosiTrack Processor PCB (PosiTrack Mother Board) contains the main processor, 2MB

FlashROM, and 2MB SRAM.

! PosiTrack Power Management PCB (PosiTrack Daughter Board) contains power conditioning circuitry, control outputs/inputs to the pan/tilt drives, and zoom/focus/iris outputs, and inputs to the lenses.

Configuration Settings

Both PosiTrack units contain switches for setting the control mode, lens control voltage, RS-232 baud rate, and AXlink address. Before installing the PosiTrack unit, you must set the DIP switches, lens control mode switches, and lens control voltage switch.

Once your settings match your systems requirements, press the SETUP button (FIG. 3) (this

procedure checks for proper lens connection). FIG. 3 shows the configuration switch access port with AXlink LED, setup button, and lens control switches accessible on the back panel.

When pressed, the SETUP button causes the PosiTrack unit to briefly exercise a preset series of

10-degree test motions on both the pan and tilt axis; allowing the installer to verify correct installation. You must configure the PosiTrack software to match the switch settings.

to the Wiring the Connectors section on page 18 for more information about the control panel.

! Flip the Lens Power switch to the left if you are only providing power to the camera/lens assembly through the PosiTrack unit.

! Flip the Lens Power switch to the right if you are providing external power to the camera/ lens assembly. By turning the switch Off, the dedicated +12 VDC stops providing additional power to the camera/lens; preventing damage to power supplies and noise in the video cables.




Installation

Installation

The PosiTrack units enable pan and tilt functionality for mounted camera/lens assemblies and provides lens control functions for teleconferencing lenses. Digital encoders are installed on both the pan and tilt drives, allowing positional feedback for presets, and to provide accurate speed control. Software adjustable stop limits are used on the pan and tilt drives to limit the range of motion.

Do not mount a PosiTrack unit in any location where the motion of the camera/lens is obstructed by any object.

Mounting the PT10 and PT30

Mount the PosiTrack units 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) or

AXB-PT30 (13.05 lbs./5.92 kg), PT10 camera/lens (10 lbs./4.54 kg), PT30 camera/lens

(30 lbs./13.61 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.

Wiring the Connectors

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 units and their camera/lenses. The Lens Power switch on the control panel, removes any power noise on the incoming video by turning power On/Off to Pin

1 of the DB-15 lens control connector.

The LENS POWER switch can turn power Off to the DB-15 pin 1 when the camera/ lens is powered from a separate supply.

FIG. 21 shows the location of each connector on the AXB-PT10. The PosiTrack Controller receives

all power from the +12 VDC and GND connections on the four-pin AXlink connector. The portion of the power directed toward the pan/tilt motors is fused to protect the PosiTrack Controller and pan/tilt motors; the fuses reset themselves.

When applying power to the AXB-PT10, adjust the soft-set pan/tilt limit stops to a safe position to prevent camera or PT10 damage.

Wiring Guidelines

The PosiTrack Controllers require 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 wiring table lists wire sizes and the maximum lengths allowable between the PT10/PT30 and the power supply. The maximum wiring lengths are based on a minimum of 13.5 VDC, available at the power supply output.

The AXB-PT10 power rating is 2 A @ 12 VDC. The AXB-PT30 power rating is

6 A @ 12 VDC. These power supplies must be provided locally.

To reduce the possible effects of ground loop noise in the video, use a single-source power supply mounted within distances specified in the following table.

Installation

The PosiTrack units are both powered from an optional local power supply. The wiring distances for the AXB-PT10 are based on a +12 VDC power supply and are capable of 2 A (continuous) with a maximum current of 20 amps.

The wiring distances for the AXB-PT30 are based on a +12 VDC power supply and are capable of

6 A (continuous) with a maximum current of 20 amps. The PosiTrack unit provides power outputs for the camera/lens combination.

Preparing captive wires

You will need a wire stripper and flat-blade screwdriver to prepare and connect the captive wires.

Never pre-tin wires for compression-type connections.

1.

Strip 0.25 inch (6.35 mm) of insulation off all wires.

2.

Insert each wire into the appropriate opening on the connector, according to the wiring diagrams and connector types described in this section.

3.

Turn the screws clockwise to secure the wire in the connector. Do not tighten the screws excessively; doing so may strip the threads and damage the connector.

Using the AXlink connector for data and power

To use the AXlink 4-pin connector for data communication with the Central Controller 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 PosiTrack Controller. FIG. 22 shows how

the power cable from the PSN6.5 is used to power the PosiTrack Controller and the GND cable is connected onto the existing GND cable on the AXlink cable coming from the Central Controller.

Always use a local power supply to power the PosiTrack unit.

Servomotor driven outputs are intended to drive servo-type motors only. The outputs have very low current (milliampere range) capability. DO NOT attempt to drive conventional motors with these outputs or you may damage the output drivers. If you are not sure about the motor type, refer to the

Specifications section on page 1for more information.

Pan Characteristics

The pan drive has a maximum pan range of ± 174° (348° total). The maximum pan rate is 35° per second. Pan travel is capable of being limited to a restricted range around the center of pan travel by software limits adjustable by the programmer/end user. Pan limits refer to the horizontal range of motion available to the PosiTrack unit. These limits are set via the Axcess program. The center position marks the center of the range.

If you are using firmware version 1.01, do not set a preset at the same location as a limit stop.

Setting the adjustable pan-limit stops

The Central Controller should be programmed by an AMX Axcess programmer before beginning.

Refer to the Specifications section on page 1 for more information on programming devices. To set

the adjustable pan-limit stops:


Installation

1.

Ensure that there is enough slack in the lens, camera, and PT10/30 AXlink cables to accommodate the full range of pan motion.

2.

Confirm that the necessary programming has been done to the system before beginning the installation process.

3.

Mount the camera controller to the desired horizontal surface.

4.

Pan the unit as far to the left as desired and enter this position into the Axcess program as the left pan-limit stop. The LEFT limit stop MUST be set left of the Home position.

5.

Pan the unit as far to the right as desired and enter this position into the Axcess program as the right pan-limit stop. The Right limit stop MUST be set right of the Home position.

6.

Pan to both programmed stop positions and ensure the pan-limit stops are set correctly.

Tilt Characteristics

The tilt drive is factory set to a maximum tilt range of ± 90

° (for a total of 180°). The maximum tilt rate is 35

° per second. Tilt limit stops refer to the vertical range of motion available to the PosiTrack unit and are set via the Axcess program. The center position marks the center of the range/

If you are using firmware version 1.01, do not set a preset at the same location as a limit stop.

Setting the adjustable tilt-limit stops

The Central Controller should be programmed by an AMX Axcess programmer before beginning.

Refer to the Specifications section on page 1 for more information on programming devices. To set

the adjustable tilt-limit stops:

1.

Ensure that there is enough slack in the lens, camera, and PosiTrack controller AXlink cables to accommodate the full range of tilt motion.

2.

Mount the PosiTrack Controller to the desired surface.

3.

Tilt the unit as far up as desired and enter this position into the Axcess program as the upper tilt-limit stop. The UP limit stop MUST be set above the Home position.

4.

Tilt the unit as far down as desired and enter this position into the Axcess program as the lower tilt-limit stop. The DOWN limit stop MUST be set below the Home position.

5.

Tilt to both stop positions and ensure the tilt-limit stops are set correctly.

If you have problems setting the range of motion on either PosiTrack units, you may be setting both limits on the same side of the HOME position. Repeat the instructions in the Pan and Tilt

Characteristics sections to correct the problem.

Diagnostic error values

In the Terminal Emulator, of the AxcessX program, you can use the Device Status command to diagnose any problems with the PosiTrack Controller. The following is an example of how to diagnose problems using the DEVICE STATUS and CLEAR ERRORS commands to obtain error values that can help you better track any problems.

1.

Turn the PosiTrack Controller On and make sure the proper connections are plugged into the unit. Open Terminal Emulator in the AxcessX program.

2.

Type DEVICE STATUS (device 90) in the Terminal Emulator. The 90 used in this example is the Device Number assigned to the PosiTrack. The same process can be sent in Axcess using

SEND_COMMAND CAM, <camera #>, "‘GET STATUS’". Refer to the GET ERRORS

Send_Command for more information.

3.

Give the Emulator at least 30 seconds to respond with an error value, if any exists.

4.

If there is an error present, the emulator displays the number 230 and other values, listed in the Error Values and Descriptions table on page 40, that correspond to particular problems encountered during the diagnostic cycle.

5.

Type SEND_COMMAND 90, "'CLEAR ERRORS'" to clear the errors in the PosiTrack unit after the problem is resolved. This command clears all the error messages that may have appeared while you were diagnosing problems.

6.

Turn the PosiTrack Controller Off and fix the problem.

7.

Turn the unit On once the problem has been fixed.

8.

Repeat steps 3 through 7 until the problem no longer exists.

When using version 2.04 firmware or higher, the PosiTrack stops all pan and tilt operations if an internal error is logged. Correct the source of the error and cycle power on the unit to resume operation. The error channels remain On until a CLEAR

ERRORS or ZAP! command is sent.

Description

Shows there is an error on the system. This value always appears in conjunction with another number. It acts as a precursor to any other error messages, as an announcement that an error has been found and the following values are the errors found.

Shows that there is a problem with the Pan Encoder on the PosiTrack. The encoder is a device that counts the revolutions of the pan motor.

Shows that there is a problem with the Tilt Encoder on the PosiTrack. The encoder is a device that counts the revolutions of the tilt motor.

Shows that there is a problem with the Pan Optical reader on the PosiTrack. The reader is a device that detects the home position of the pan gear.

Shows that there is a problem with the Tilt Optical reader on the PosiTrack. The reader is a device that detects the home position of the tilt gear.

Shows that there is a Worm ECC error (pan) on the system. This error occurs when the worn gear is not fitting properly along the pan’s gears.

Shows that there is a Worm Eccentric error (tilt) on the system. This error occurs when the worm gear is not fitting properly along the tilt’s gears.

Shows that the pan stalled. Occurs when the pan motor locks up.

Shows that the tilt stalled. Occurs when the tilt motor locks up.

If there are any errors found, the 230 error value displays that there is an error, and is then followed by another number to indicate the precise problem. For example, a problem with the Pan Encoder will return the message: 230 , 240 .

Enables software handshaking on the device.

RS-232 Send_Strings

PosiTracks have special Send_String escape sequences. If any of the three-character combinations listed below are found anywhere within a Send_String program instruction, they are treated as a command and not the literal characters.

RS-232 Send_Strings

"'27,18,0'"

"'27,18,1'"

"'27,19,<time>'"

"'27,20,0'"

"'27,20,1'"

Clears the ninth data bit to 0 for all subsequent characters to be transmitted. It is used in conjunction with the 'B9MON' command.

Sets the ninth bit to 1 for all subsequent characters to be transmitted. It is used in conjunction with the 'B9MON' command.

Inserts a delay before the next character to be transmitted.

Variable: time = 1 - 255 in 1 millisecond increments

De-asserts RTS hardware handshake output high.

Asserts an RTS hardware handshake output low.

In 485 mode, if the delay escape code characters are the last in the Tx buffer, the 485

Tx output will tri-state at the beginning of the delay.

If you need to send a string containing sequences "27,17," "27,18," "27,19," or "27,20," use two

Send_String commands. The first containing characters up to and including "27", the second beginning with "17", "18", "19", or "20", and all subsequent characters.

To send the string "$1B,'C',0,27,17,13" , use:

{

SEND_STRING <dev>, ’"$1B,'C',0,27"’

SEND_STRING <dev>, ’"17,13"’

}

Stand-Alone RS-232 Protocol

The stand-alone RS-232 protocol (in the General Format table) is the AXlink-to-PC Comm Port

Interface (AXB-PCCOM) protocol, with the inclusion of the device byte of the protocol being fixed at 0.

Upgrading the Firmware

Upgrading the Firmware

Your PC must be connected to the PROGRAM DB-9 connector on the Controller or camera control unit connector using a Programming Cable in order to upgrade the firmware in the panel.

If power is lost during the download process, the unit powers up with the same set of code it had prior to the download. There is a small window during which a loss of power can be catastrophic. If power is lost between the erase of flash memory and the completion of copying the new boot code from RAM to flash memory, the unit will not operate at all when power returns.

If you have not already installed the SOFTROM program, do so by following the steps contained on the AMX Control Disc.

Configuration

To configure the communication setting for the SOFTROM program:

1.

Press F1, the Configuration screen appears.

2.

Using the up/down arrow keys, select the communications port you are using to interface with the controller and press ENTER.

3.

Using the right arrow key, move to the BAUD RATE column. Then, use the up/down arrow keys to select the interface communications speed and press ENTER. Be sure the BAUD

RATE selections match the setting on the Controller.

4.

Press F10 to save the communication settings and to exit the CONFIGURE screen.

Downloading the Firmware

To download the firmware:

1.

Press F5 to acquire the list of online programmable devices.

You can press F2 to select all ONLINE programmable devices and F3 to clear all devices.

2.

Using the up/down arrow keys, select your firmware versions listed in the Firmware column of the screen, and press ENTER.

3.

Using the Tab key, switch to the ONLINE MASTERS list.

4.

Using the up/down arrow keys, select the device to be programmed.

5.

Press ENTER for each device as it is selected

6.

Press F4 to program the selected device; a loading message appears.

7.

Press F5 to refresh the screen. Verify that the selected device has the correct firmware version.

If any devices still appear with an old firmware version, repeat steps 3 - 5 until it appears with the correct version

Firmware can be downloaded to multiple device numbers automatically. If multiple devices are selected, the bottom half of the loading bar indicates the percentage complete for the selected devices.

8.

Press F10 to exit the SOFTROM program.
