HOLUX GR-231 Bluetooth GPS Receiver Manual

1. Overview

(Fig.1)

The

HOLUX

GR-231 Smart wire-less Bluetooth GPS Receiver (Fig. 1) is a total

solution GPS receiver with Bluetooth, UART interface and built-in rechargeable battery

for high sensitivity to tracking signal. GR-231 design is based on SiRF Star IIe/LP low

power Architecture.

GR-231 is a dual-function GPS receiver. Not only transmit satellite information

through the PDA or Notebook with Bluetooth interfaces but also is a G-Mouse GPS

receiver through a data cable to deliver satellite signal to the device without Bluetooth

interface.

This positioning application meets strict needs such as car navigation, mapping,

surveying, security, agriculture and so on. Only clear view of sky and certain power

supply are necessary to the unit. GR-231 contacts to other device through Bluetooth

device, compatible interface of RS-232 or USB, and built-in recharge battery to save

satellite information such as the status of satellite signal, the last location, date and time

of last use.

3

HOLUX GR-231 Bluetooth GPS Receiver Manual

With low power consumption, the GR-231 tracks up to 12 satellites at a time,

re-acquires satellite signals in 100 ms and updates position data every second.

Trickle-Power allows the unit operates a fraction of the time and Push-to-Fix permits

user to have a quick position fix even though the receiver usually stays off.

7. Driver Installation

You can use any GR231 accessories data cable without installing driver except

GR230-A2 USB cable. The following is the steps of installation GR230-A2 USB

cable.

7.1 System Requirement

CPU: IBM, Pentium, or other compatible PC.
Memory: above 16 MB

System: Windows 98/Me/2000/XP

7.2 Installation

I. Copy entire GM231 USB folder from CD to hard disk.

II. Connect GR-230-A2 USB connector to computer without GR-231 GPS receiver.

While the computer automatically starts the installation program, please direct

the driver to the GR231 USB folder.

7.3 Important

Verify the COM port to start using your own navigation software.

I. Click <Start> menu, select → <Setting>, then enter→ <Controller>

II. After entering <Controller>, and select <System>.

III. Select <Device Manager>.

IV. Find the < Connector(COM & LPT)> and check the Virtual COM Port, which

was created by the USB driver.

Please note that the virtual COM port number might be different from every

computer. Before using navigation software, please confirm the COM Port numbers

created by your computer and provided by your navigation software. Otherwise, the

navigating software won’t receive the satellite signal, because of the un-match

COM Port setting.

8. Warranty

The GR-231 is warranted to be free from defects in material and functions for a

period of one year from the date of purchase. Any failure of this product within this period

under normal conditions will be replaced at no charge to the customers.
