Your Laser Tracker ships as a complete measuring system: the instrument itself, the cabling, and a set of accessories packed in the transport container. The AT500 and the AT930 share most of that hardware, and the differences come down to one thing: the AT930 needs a separate AT Controller, while the AT500 has the controller built into the instrument.

What Dusty ships you

You receive one laser tracker — the Leica Absolute Tracker AT500, the AT930, or the AT930-NRT. Which model you get determines the radio and cabling in the case.

AT500

☐  Leica Absolute Tracker AT500	☐  AC Power Adapter	☐  AC Power Extension
☐  4 × Leica AT500 Batteries	☐  2 × Tracker Battery Charger	☐  2 × Double Shielded Cat6 Ethernet Cable
☐  2 × Milwaukee M18 Battery	☐  Radio 2 or Radio 3	☐  Radio Power Adapter

AT930

☐  Leica Absolute Tracker AT930	☐  AC Power Adapter	☐  AC Power Extension
☐  Leica AT930 Controller	☐  Tracker-to-Controller Cable	☐  2 × Double Shielded Cat6 Ethernet Cable
☐  2 × Radio 1 Power Cable (USB Type A to Type B Cable)	☐  Radio 1 or Radio 3	☐  Radio Power Adapter (if needed for Radio 2)

AT930-NRT

☐  Leica Absolute Tracker AT930	☐  AC Power Adapter	☐  AC Power Extension
☐  Leica AT930 Controller	☐  Tracker-to-Controller Cable	☐  2 × Double Shielded Cat6 Ethernet Cable
☐  2 × Milwaukee M18 Battery	☐  Radio 2 or Radio 3	☐  Radio Power Adapter

The two trackers handle power differently. The AT500 has internal GEB364 batteries and ships with two of them. The AT930 has no internal battery: it draws power through the AT Controller, which takes an AC power supply, a battery unit, or both. Leica does not include a battery unit in the AT930 container.

Both containers hold the laser tracker, cabling, and radio. The AT500 container adds batteries and chargers. The AT930 container adds the AT Controller and its sensor cable.

The AT500 container has no sensor cable because there is no separate controller to connect. The AT930 container has no batteries or charger because the AT930 has no internal battery.

AT500 instrument components

Part	What it does
Carry handle	Lift point on top of the instrument.
Coaxial optics	Angle and distance measurement, and the exit port for the visible pointer laser beam.
IR receiver	Receives commands from the AT Remote Control 400. Not used for Dusty.
PowerLock	Finds and locks onto the reflector without you aiming the tracker (10° field of view).
Overview camera	Shows reflectors on screen so you can identify and select one to lock onto. Focus and aperture are fixed. Not used for Dusty.
Circular level	Bubble level on the back of the instrument, used to level the tracker.
PowerLock LEDs	Indicate PowerLock state.
Connector area	Where the cables land.
Status LEDs	Report system state.
Telescope	Houses the Absolute Distance Meter (ADM) and Automatic Target Recognition (ATR).

Description of AT500 Status LEDs

	Red	Tracker is warming up.
	Red, blue, red	Tracker is not locked to a reflector.
	Solid green	Tracker is locked to a reflector. Tracker is not connected to a radio.
	Flashing green	Tracker is locked to a reflector. Tracker is connected to a radio.
	Off	Tracker is off.

Buttons and LEDs on the left side

Control	What it does
Battery level LEDs	Show remaining charge, and flag battery overheating or an out-of-range charging temperature.
Power button and status LED	Long press turns the sensor on or off. Short press with the sensor off shows battery charge for five seconds.
Bluetooth status LED and pairing button	Press and hold 1 to 2 seconds to pair a new device. Not used for Dusty.
WLAN status LED	Shows wireless state. Not used for Dusty.

RESET button

The RESET button sits inside the battery compartment on the right side of the instrument, not with the other buttons on the left. DO NOT PRESS. Pressing the RESET button will unconfigure the tracker making it incompatible with the radio and the FieldPrinter.

AT500 connectors

AT930 instrument components

Description of AT930 Status LEDs

The AT930 uses three LED colors: Red, Green, and Blue in various patterns. Use the table below to identify what each combination means.

AT Controller components

The AT Controller runs the system software and is the interface between the AT930 and the radio. The AT500 has no equivalent unit.

Top

Part	What it does
Power status LED	Green and static when the controller is powered up. Off means controller power is off.
WLAN status LED	Yellow and static when the WLAN module is active. Not used for Dusty.
Touch-sensitive status display	Shows system information pages.
Main power switch	Turns on both the AT Controller and the instrument.
Clip for Universal Stand Fixture	On the back. Attaches the controller to the stand.
Connectors	Front panel, listed below.

Front connectors

One port on the front panel is not supported.

Real-Time Feature Pack and the AT930-NRT

RTFP (Real-Time Feature Pack)

The optional Real-Time Feature Pack for Absolute Tracker AT930/AT960 is designed to provide cyclic measurement data in real-time over an industrial field bus protocol, for example EtherCAT, with minimum jitter and small latency. The RTFP acts as a slave in the external automation bus system.

The RTFP is an add-on to the AT Controller which is service fitted by Dusty.

Laser tracker sets with an RTFP will come with a Radio 1 or Radio 3. Laser tracker sets without an RTFP will come with a Radio 2 or Radio 3.

Shutting the AT930 down

Always shut the AT930 system down properly. Press the power switch for 2 seconds, then release it as soon as the shut-down splash screen appears.
