1. Introduction
1.1 Overview
The DA-80101 series GPS receiver incorporates low noise, high sensitivity, low power consumption
SiRF StarⅢchipset solution in a compact, waterproof enclosure. 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,
re-acquires satellite signals less than 1 second (average) and updates position data every second.
1.2 Features
The DA-80101 series provides a host of features that make it easy for integration and use.
1. With SiRF StarⅢhigh sensitivity chipset.
2. High performance receiver tracks up to 20 satellites.
3. Compact design ideal for applications with minimal space.
4. A rechargeable battery sustains internal clock and memory.
5. User initialization is not required.
6. One full duplex serial RS-232 port or USB port meets all applications.
7. Waterproof design for all weather.
8. Built-in low noise, high gain active antenna.
9. LED display provides users visible positioning status.
10. Support Standard NMEA-0183 and SiRF Binary protocol.

2. Hardware Interface
2.1 Dimension
The receiver enclosure is with the dimension:
59.7 mm (L) x 39 mm (W) x 16.4 mm (H)
2.2 Interface
The DA-80101 series GPS receiver includes a variety of models. The main difference is the output
connector. These interface options are described in the following.
DA-80101
DA-80101 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 DA-80101 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
purchased.

2.3 Connector
Following are the description of the output connector.
DA-80101
Standard cable is two meters in length with a female PS-2 Jack as shown in the following.
Pin assignment of standard PS-2 Din Jack connector is in the following drawing and table.
Pin Signal
1 Tx (RS-232)
2 +5VDC
3 Tx (TTL)
4 GND
5 Rx (TTL)
6 Rx (RS-232)
DA-80101 PS2
The accessory is a Y-cable with a cigarette lighter adapter to a vehicle’s front power socket. Please
refer to the drawing on previous page. The Y cable is with one branch of PS2 Plug to connect to the
PS2 Jack of DA-80101, while the other branch to connect to a PDA. However, due to the many
variety of PDAs, an appropriate adaptor type must be specified.
For users with PC or Notebook, a USB interface cable or RS-232 adaptor cable shown in previous page
may be used. Drivers for the USB interface cable are available on a CD associated with the cable.
These are optional purchases.
