No target readings in PDA. 

Target LEDs illuminated 

(means target is detecting 

laser) 

 

 

 

 

Check Zigbee radio communication. There should be 2 green LED 

lights in PDA boot, (1) solid, (1) blinking. If no lights, hold green 

power button down for three seconds and release, restart PDA and 

tap Cancel on Unidentified USB Device Pop-up. 

 

Check Radio Receiver battery – plug in A/C adapter to ensure it has 

power. 

 

Ensure the check box to the left of the display window in Read15 

(see manual) is checked for each target. 

 

Ensure channel setting (system ID) on A-1519/1520 matches the 

setting in PDA – See Read15 Manual. 

 

Ensure Target ID on A-1519/1520 is set to 1-4 for first screen or 5-

8 in second screen in Read15. 

 

Target is too close to laser (target LEDs blink). 

 

Check for reflections. 

 

Check for strobe lights and rotary lights. 

 

Check for excess background light (normally target LEDs blink)  

 

Plug target into computer via USB cable and open Target Utility 

software.  If software shows reading, then there is probably a 

problem with the radio. 

 

Ensure PDA has same radio frequency as Target (900 MHz or 2.4 

GHz) 

 

Hit reset switch on target (use paper clip in hole near Target 

ID/Channel Selector Panel). 

 

Laser could be hitting too low or high on target window (it should 

be near the window).  It is possible for the laser to activate the auto 

wake up feature of target, but not enough of the beam is hitting the 

PSD (target sensor) to get a reading.

No target readings in 

software. Target LED 

illuminated 

 

Ensure A-910 radio base station is connected to USB port. 

 

Ensure the correct COM port is selected for the USB bridge controller – 

see Windows Device Manager (has to be lower than COM10). 

 

Check Device Manager in Windows Control Panel. Set COM port for 

USB bridge controller lower than COM10. 

 

Ensure the correct target ID is chosen in Machine Tool Geometry or 

Read8 software.    

 

Ensure channel setting (system ID) on A-1519/1520 matches the setting in 

A-910 (see the Target Utility Manual). 

 

Ensure SND/RC LEDs on A-910 are blinking (see the Target Utility 

Manual). 

 

Ensure ACTUAL TARGETS (RADIO in Plane5) is selected in Read8, 

Plane5 or Machine Tool Geometry software. 

 

Ensure antenna is connected to A-910. 

 

Target may be too close to laser (target LED’s blink). 

 

Check for excess background light (normally target LEDs blink). 

 

Ensure A-910 radio base station has same radio frequency as target (900 

MHz or 2.4 GHz). 

 

Laser could be hitting too low or high on target window (it should be near 

the window).  It’s possible for the laser to activate the auto wake up 

feature of target, but not enough of the beam is hitting the PSD (target 

sensor) to get a reading.
