HOLUX GPSlim236 Wireless Bluetooth GPS Receiver Manual 

1. Overview 

The Holux GPS receiver is a total solution GPS receiver with Bluetooth, UART interface and built-in rechargeable battery for high sensitivity to tracking signal. GPSlim 236 design is based on SiRF Star III low power Architecture. 

GPSlim 236 is a dual-function GPS receiver. Not only does it transmit satellite information through the PDA or Notebook with Bluetooth interfaces but it is also 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 a clear view of the sky and a power supply are necessary to the unit. GPSlim 236 connects to other devices through a Bluetooth compatible interface, RS-232 or USB, and built-in rechargeable battery to save satellite information such as the status of satellite signal, the last location, date and time of last use. 

With low power consumption, the GPSlim 236 tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second. Trickle-Power allows the unit to operate at a fraction of the time and Push-to-Fix permits the user to have a quick position fix even though the receiver usually stays off.

4. Getting Started 

STEP 1. Charge Battery 
Please charge battery until the LED turns off for the first time. 

Power cable plug in Power cable connect to power socket to charge battery

Battery indicator light: 
Power too low -------- red LED 
Charging -------------- green LED 
Full or Not charging -- LED off 

STEP 2. Turn on Power 

Bluetooth Status

When you turn on GPSlim236 power it will begin to search for a bluetooth device, the blue LED will blink once per second.  Once the data is transferring, the blue LED will blink once per 3 seconds.  If the receiver needs to reconnect to the bluetooth device, the blue LED will blink once per second.  
Note: Some PDAs have to re-open Bluetooth manager for Bluetooth device re-connection. 

GPS Status -- Put GPSlim236 in clear view of the sky without any obstruction for better satellite acquisition.

Turn on GPSlim236 Power, you will see a steady orange LED when the receiver is searching for a GPS fix.  You will see the orange LED blinking when your position is fixed.

Turn off GPSlim236, note that the orange LED will be off.



4.1. Hardware Description 

1). Body description see Fig. 2: 

The image of the GPSlim236 receiver is placed diagonally with the Power Jack facing down and to the left.  The LEDs from left to right are first the LED for GPS (Orange light),. Second, the Bluetooth LED (Blue light) , and the LED for the Battery (Red or Green light)
The Power Jack is located on the bottom edge in the middle.

2). LED status : 

Bluetooth is represented by the color Blue.  It's status can be determined by the frequency of the blinking of the blue light. If the blue light is blinking:
* 1 times / 1 sec - Searching for Bluetooth Device 
* 1 time / 1 sec - Standby Mode 
* 1 time / 3 sec - Transferring Data 
 
The battery is represented by the colors Red and Green.  When the light is Red, the Power is too low.  When the light is Green the battery is charging.  When there is no light, the battery is full or not charging.

GPS is represented by the color orange.  If the orange light is on continuously, the receiver is acquiring satellites.  If the light is blinking, the receiver has a position fix.
