4 Evaluation Kit Setup
4.1 Installing the USB Drivers
Before connecting the SE873 Evaluation Kit, install the necessary USB drivers.
Double-click the USB driver executable CDM v2.12.00 WHQL Certified.exe, and follow
the directions to install the USB drivers.
Figure 4-1 Hardware Installation
Click “Continue Anyway” to install the USB COM port driver
When the EVK board is connected to a personal computer USB port, the driver will
create a COM port.
Use the Windows “Device Manager” to check the identification of the new COM port.
This port identification is necessary for EVK tools to connect to the evaluation kit.

4.2 Installing SiRFLive
Minimum PC requirements:
Pentium CPU 2 GHz
1 GB of RAM
100 MB hard drive
Recommended:
2 GB of RAM
1280 x 1024 screen resolution
Double-click the SiRFLiveInstaller_MKTG_Lite.msi file to install the SiRFLive program, then
follow the installer directions until finished.
It is recommended that SiRFLive be installed to the default location – C:\CSR\SiRFLive.
SE873 EVK User Guide SE873 Evaluation Board Operation
1VV0301214 Rev. 1 Page 20 of 43 2016-10-24
5 SE873 Evaluation Board Operation
1. Power will be applied to the SE873 module when the USB interface is connected to a
USB port on a personal computer. When the EVK On-Off switch is turned ON, the
module ON_OFF pin will be powered up and the module will begin operation.
2. Connect the provided GNSS Active Antenna.
NOTE: The evaluation kit supplies 3.3V to the antenna. For a passive antenna, jumper PL106
must be removed.
3. Place the antenna face up in a location with a clear view of open sky.
4. Use SiRFLive or TelitView to send commands to and display output from the module.

1VV0301214 Rev. 1 Page 21 of 43 2016-10-24
6 Using SiRFLive
6.1 Starting SiRFLive
1. Connect Power and Antenna to the EVK.
See Section Error! Reference source not found. Error! Reference source not
und..
2. Turn on the EVK Power switch (up).
3. Launch the SiRFLive application.
4. Connection Settings window: Select the Receiver. This is where you select the COM
port that was previously created by the USB driver. See Section Error! Reference
ource not found. Error! Reference source not found..
Use the Receiver drop-down box.
Figure 6-1 Connection settings window
5. If the default Baud Rate is 115200 and Protocol is OSP on your EVK, leave those
boxes with their values as presented.
If the default Baud Rate is 9600 and Protocol is NMEA on your EVK, change those
boxes to match.
If you have changed the receiver’s defaults, select them using the Baud Rate and
Protocol drop-down boxes.
6. Click OK. The remainder of these screen captures will show NMEA protocol. OSP will
present somewhat different data.
7. If necessary, click Receiver, then Connect on the menu bar.

8. The SE873 defaults to a power-saving mode called SmartGNSS2, so you may see
the GLONASS satellites disappear from the Radar View. This is normal. If you wish to
command the full-time use of GLONASS as well as GPS, use the following
procedure:
a. Click Receiver, Command, then Switch Comm Settings.
Figure 6-3 Switch Comm Settings window
b. Verify that Switch Protocol (to OSP) and Baud Rate of 115200 are
selected as shown above.
c. Click Set. The receiver and display will both switch to OSP protocol at
115,200 bps.

6.4.1 Reset commands
(Tool Bar icon)
Select from the Menu Bar Receiver, Command, Reset
or click the Reset icon on the Tool Bar.
Resets are used to measure the TTFF of the receiver. The TTFF/Nav Accuracy window
conveniently displays the TTFF in seconds and Navigation accuracy based on the Reference
Location.
Reference Location allows the user to change the position used as the reference. This helps
determine position accuracy in conjunction with Time-To-First-Fix values.

6.4.2 Switching Protocols
On the Menu Bar, select Receiver, Command, Switch COMM Settings.
Click Set to apply settings.
OSP has many commands that are not available in NMEA. Therefore, switching to OSP is
recommended for testing purposes.

6.4.4 Enabling 5Hz Update
First, set the baud rate high enough so that characters are not dropped. The default rates
(9600 for NMEA and 115.200 for OSP) may be too low depending on the configured message
set.
Through the SiRFLive Menu Bar, click Receiver, Navigation, Set 5Hz Nav and select Enable
5Hz Nav.

8 Software Interface
The host serial I/O port (UART, I2C, or SPI) supports full duplex communication between the
receiver and the user.
The default UART configuration is: NMEA, 9600 bps, 8 data bits, no parity, and 1 stop bit.
Two protocols are available for data output and command input:
NMEA-0183 V4.10
SiRF One Socket Protocol (OSP)
More information regarding the software interface can be found in the Telit CSR Software User
Guide. Access to this document requires a Non-Disclosure Agreement (NDA) with Telit.

Proprietary Messages
The receiver can issue several proprietary NMEA output messages ($PSRF) which report
additional receiver data and status information.

8.2 NMEA Input Commands
The receiver uses NMEA proprietary messages for commands and command responses. This
interface provides configuration and control over selected firmware features and operational
properties of the module.
The format of a command is:
$<command-ID>[,<parameters>]*<cr><lf>
Commands are NMEA proprietary format and begin with “$PSRF”.
Parameters, if present, are comma-delimited as specified in the NMEA
8.3 One Socket Protocol (OSP) Output Messages
SiRF One Socket Protocol (OSP) is supported. This is an extension of the existing SiRF Binary
protocol. The following messages are output once per second:
− MID 2
− MID 3
− MID 4
− MID 7
− MID 9
− MID 41
− MID 64 SUB ID 2 (One message for each satellite being tracked).
− MID 138
