GPS Mouse Receiver(SiRF-III)
The ProGin SGM-209 series GPS receiver incorporates low noise, high sensitivity, low power consumption SiRF Star chipset solution in a compact, waterproof enclosure. ¢ó The receiver is very suitable for broad applications such as car navigation, mapping, surveying, etc. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other host device via
one full duplex serial communication RS-232 port or one universal USB port. With its ultra low power consumption, the receiver tracks up to 20 satellites at a time while offering fast time-to-first-fix.
The SGM-209 series provides a host of features that make it easy for integration and use.
1. Based on SiRF¡¯s GSC3f low power single chip.
2. High performance: -159dBm tracking sensitivity.
3. Low power: 31/44mA at continuous tracking.
4. Backup battery support for faster position fix.
5. Waterproof design for all weather..
6. One full duplex serial RS-232 port or USB port meets all applications.
7. Blue LED for position fix indication.
8. Built-in low noise, high gain active antenna.
9. SBAS (WAAS and EGNOS) support (optional).
10. Support Standard NMEA-0183 and SiRF Binary protocol.

2. Hardware Interface
The receiver enclosure is with the dimension:
36 mm (L) x 42 mm (W) x 15 mm (H)
The SGM-209 series GPS receiver includes a variety of models. The main difference is the output
connector. These interface options are described in the following.
SGM-209 is with a PS2 DIN jack output connector. Following figure shows various connection
arrangements. The one-piece cigarette lighter adapter assembly allows you to utilize power from the
front power socket of vehicles. Simply connect SGM-209 to the PS-2 plug of the adapter assembly
and link the other connector to your PDA. For Notebook users, a PS-2 to USB adapter assembly is
required. This is an optional purchase. A CD with USB driver is provided with the assembly. For
users intend to use RS-232 port of PC or Notebook, the other optional adaptor assembly can be
This model provides users a direct connection to a Notebook or other host devices with USB
connectors. USB driver is required and provided in the CD.
This model provides users a direct connection to SN4 connector. It is convenient for users with SN4
connector in their host devices.
Following are the description of the output connector.
Standard cable is two meters in length with a female PS-2 Jack. Pin assignment of standard PS-2 Din
Jack connector is in the following drawing and table.
