Pre-Sales FAQ



Pre-Sales Question - FAQ

Following is a list of pre-sales questions and answers.  We've seperated it into categories for convenience.


I've seen similar radios powered by 4 AA batteries.  Why do you use an internal battery?

AA NiMh batteries only have an output voltage of 1.2 Volts DC.  So the effective total voltage supply is 4 times 1.2 volts for a total of 4.8 volts.  While our Bluetooth radios are very efficient with power consumption, they require 5 - 12 Volts to function properly.  This is why we use an internal 6 Volt battery.

Can the internal battery be replaced?

The internal battery can be replaced when required.  The internal system has been setup with a quick connector for easy battery swapping.

How is the internal battery charged?

We use an advanced Li-Ion smart charger.  The smart charger ensures that the batteries are charged at the proper voltage, and will automatically switch to a trickle charge when the battery is fully charged.

How long does it take to charge a battery?

Normally it will take approximately 2 hours to fully charge a battery. 

Can I charge the internal battery anytime I want to?

Yes you can. You probably have heard that in order to maintain the life and performance of rechargeable batteries, you have to fully drain the batteries before recharging them. Thanks to "memory free" technology used for Li-Ion batteries, you can charge them anytime you wish, regardless if the batteries are fully drained or not.

How many times can I recharge the internal battery?

The number of times you can recharge your batteries will depend on the operating parameters, such as drain rate, battery care, etc.  In general, under desirable condition, Li-Ion can last 500 recharges or more.


Can FieldHawk draw power from my instrument?


Which instruments are you compatible with?

Pretty much every model made.  If you can connect your data collector to your instrument with a cable (direct connect), you can use FieldHawk.  Think of FieldHawk as a "virtual" cable; it replaces your cable with a wireless link.

What communication parameters do you support?

FieldHawk supports the following settings.

Serial Port Settings  Values
Baud Rate
1200, 2400, 4800, 9600, 19200, 57600, 115200, 230400
Data Bite
None, Even, Odd
Stop Bit
1, 2
Hardware Flow Control
Use, Don't Use

Do you support a wireless radio connection to a FieldHawk radio?

Absolutely. All you do is use the Bluetooth radio in your data collector.


When using the a single radio, what kind of range can I expect?

This depends on the Bluetooth Class in your data collector.  Most data collectors use Class 2 which has a effective range of 10 meters or 30 feet.  With FieldHawk, on average you can expect to get 20 - 50 meters (65 - 165 feet).

Can the radios be configured by me?

The default configuration for FieldHawk is 19200-None-1.  Included with your purchase is a software configuration utility that can be used to change the communication parameters. 

If there are objects in the way, will the radio link be affected?

FieldHawk uses an advaced Bluetooth radio system that automtically reconnects when the connection is lost. Since these radios are being used with total stations, you will normally have a clear line of sight.

Does the radio link connection slow down the further you are away?

At extreme distances you might notice that your shots take a little longer, but only by a few seconds.
