USB Base unit. No add-on modules or cables are needed because the wireless is built directly into
the Diamondback Indicator.
In order to send readings the Wireless Diamondback needs to be associated to a specific Base Unit
connected to a PC.
STEPS TO ASSOCIATE TO A USB BASE:
1. Prior to association the MicroRidge Mobile Collect Setup Utility should be installed on the PC
and the base should be connected to the USB port. Refer to the Utility User Manual that came
with your base.
2. Open the Mobile Collect Setup Utility and select “Find Base” The base settings should
populate the data entry field.
3. In the utility Select the Mobile Module Setup Tab
4. On the indicator Press and Hold the “in/mm” button for 3 seconds to put the Diamondback into
setup mode. You will see “SEt UP” flash on the screen and the LEFT/RIGHT tolerance arrows
will continue to flash.
5. Once the Diamondback is in SETUP mode, press and release the “in/mm” button again to send
the indicator parameters to the base. You should see the data fields such as Module ID populate
in the utility.
6. In the wireless utility select the box “associate with Base unit connected to this setup program”
and press the “Send Setup to Mobile Module” button in the lower right hand corner.
7. Press and Hold the “in/mm” button on the indicator for 3 seconds to exit the setup mode. After
5 minutes of inactivity the unit will exit the setup mode automatically.
Unit should now be associated with the base and when the blue “SEND DATA” button is pressed
the reading is transmitted to the base. The LCD “DATA” icon appears in the upper right hand
corner of the LCD during transmission. If the base unit did not receive the reading correctly the
message “rF Err” will appear on the LCD.
The range of wireless transmission is greatly affected by the environment in which the unit is used.
Average distance for good transmissions is approximately 100 feet.
The AAA Alkaline batteries that come with the unit are good for approximately 500,000 data
transmissions.
