SXBlue II GPS Series Technical Reference Manual
3
The connections required by the SXBlue II GPS are very straightforward. All cables necessary
for complete operation are provided.
-
The RS-232 port is a D-Sub 9-pin female connector
-
The USB port is a Type-B female connector
-
The Bluetooth port is a Class 1 type.
The SXBlue II GPS offers three communication options: Serial RS-232, USB and Bluetooth. In
order to use the USB port, a driver (supplied on CD-ROM with the unit) must be installed on
your computer. Refer to section 1.3 for instructions on how to install the drivers. In order to use
the Bluetooth (wireless) communication of the SXBlue II GPS, you must use a Bluetooth-
enabled PDA or computer. If you have a PDA or computer that does not support Bluetooth
natively, you can supplement your computing device with a Bluetooth card (CF, PCMCIA, SD)
or USB dongle. When configuring your Bluetooth device for communication with the SXBlue II
GPS, make sure that pairing (or bonding) with password (or passkey) is not activated. A
miniature DIP switch (see Figure 1-2) allows powering off of the Bluetooth radio when the
receiver is operated in places where the use of wireless communication is prohibited. Refer to
section 1.3.2 for more information on sample Bluetooth setups.
1.2.2 Battery Pack
The Lithium-Ion battery pack attaches to the receiver with four thumb screws. Modular contacts
are used to supply power to the receiver. Even though the Li-Ion battery pack has a built-in
protection circuitry, care must be taken not to
short the contacts on the battery pack.
Also, membrane vents are used on both the
receiver and battery pack. These small holes
should not be punctured, obstructed or
covered by labels or stickers.
The battery pack features an intelligent
battery “fuel gauge” that shows the level of
charge (see Figure 1-1). On initial usage, it
might take one or two charge/discharge
cycles for the gauge to reflect the proper
charge level. When unit is not used for an
extended period of time, it is normal that the
battery pack discharges. The field autonomy
of the pack is roughly 9.5 to 15 hours
depending on the model and after 500 cycles,
battery capacity starts decreasing to about
80%.

Since the SXBlue II GPS uses Li-Ion battery chemistry, there is no memory effect as for NiMH
or NiCad batteries; therefore it is not necessary to discharge the pack before recharging it.
Only
proper Li-Ion battery charger must be used with the SXBlue II GPS battery
. Using any
other type of charger might result in explosion and injuries. The SXBlue II GPS battery pack
