4.

What is the RMA Process for Trimble InTech's GNSS OEM Receiver Boards?

The RMA Process for Trimble OEM GNSS Receiver Boards, OEM GNSS Enclosures, and Antennas, is begun by email to Repair_Services@Trimble.com.  The customer will receive a Return Merchandise Number (RMA) and further shipping instructions. 

Alternatively, if the customer has a login for http://support.trimble.com/arsys/shared/login.jsp, the customer can fill out RMA forms directly and receive further shipping instructions.

5.

How do I enable Data Logging using the Trimble OEM GNSS Receiver Boards?

Data Logging can be extremely useful during any evaluation process. The Web user Interface can be used to set the data output and a binary data collection program (RCAPTURE) can be used for recording.

5.1 RT17/27 Output using the Web User Interface.

Data Logging, or RT17/27 Output, is enabled using the Web User Interface. RT17/27 Output can be configured in a variety of ways using ‘I/O Configuration’ screen.


5.1.1 Select any Serial, USB, or Ethernet port for configuration.

The above example will configure Serial1/COM1 (38400/Parity None) for RT17/27 Output of both Measurements and Positions at 1Hz. The options selected exclude ‘Smooth Pseudorange’ and ‘Smooth Phase’ as the raw data are usually of greater interest.

A data output rate of 1Hz is sufficient for static data collection. However, for dynamic situations a higher (5Hz or higher) output rate is recommended.

5.2. Record RT17/27 Output.

RCAPTURE is recommended to record RT17/27 data, although any binary logging program can work.  RCAPTURE can be downloaded from the ‘Receiver Configuration Software’ section located at: http://www.trimble.com/gnss-inertial/bd970.aspx?dtID=support

The RCAPTURE.zip file contains instructions for operation.

6.

What is the BD9xx RTK Engine Time Out set to?

Following a loss of RTK Corrections, the default RTK Engine Time Out is set to 20 seconds by default.

7.

How do I enable NMEA (GGA and HDT) output from a BD9xx OEM Receiver?

NMEA output can be enabled via 64h APPFILE Commands.  Documentation of the 64h APPFILE Commands are located within the OEM Receiver Help online manual located at:

• OEM Receiver Help Online Manual: 
  http://www.trimble.com/OEM_ReceiverHelp
• 64h APPFILE Documentation: 
  http://www.trimble.com/OEM_ReceiverHelp/v4.91/en/ICD_Pkt_Command64hAPPFILE.html

The following table contains some common NMEA (GGA and HDT) output options:

8.

Can InTech provide I/O Board Reference Designs?

GNSS OEM Engineering Support can provide the I/O Board Reference Designs in the following formats:
• .DSN
• .pdf

Also, see the ‘Electrical System Integration’ section of the OEM Receiver Help Online Manual for the selected BD9xx product.
http://www.trimble.com/OEM_ReceiverHelp  (Product Guides » BD9xx GNSS Receiver Module » Electrical System Integration) 

Our I/O Evaluation Boards may also be used as reference designs.

9.

What are RAIM and FDE? Do the Trimble InTech BD9xx OEM Receiver Boards have RAIM and FDE?

RAIM (Receiver Autonomous Integrity Monitoring) and FDE (Fault Detection and Exclusion) are included on Trimble InTech GNSS OEM Receiver boards.

The RAIM/FDE algorithms determine individual SV’s which are not consistent in the solution (pseudoranges, clocks, ephemerides, etc.). Faults are flagged in the RT27, RT29, NMEA GBS & GRS, and on the Web UI in the Satellite Tracking Table.

Code solutions have always used the RAIM flags to exclude SV’s.

In the v4.8x & later firmware the RTK engine also uses the RAIM flags to exclude SV’s from RTK solutions.

10.

What are the Ethernet settings on the Trimble InTech BD9xx OEM Receiver Boards?

BD9xx OEM Receiver Boards come equipped with an Ethernet port.  This allows the receiver to connect to an Ethernet network.  Access permits configuration and monitoring of the receiver without the need for a serial cable connection.

The receiver requires the following Ethernet settings:

• IP Setup: Static or DHCP
• IP Address
• Netmask
• Broadcast
• Gateway

• DNS Address
• HTTP Port
• Username (if applicable)
• Password (if applicable)

The default setting for the HTTP Port is 80.  The HTTP Port is not assigned by the network.  HTTP Port 80 is the standard port for web servers, this allows for only entering the IP address in most web browsers (Firefox, Chrome, etc…). 
• For example (192.168.1.1) –using HTTP Port 80.

If the receiver is set up to use a port other than 80, the IP address and port will need to be entered into the web browser. 
• For example (192.168.1.1:5825) –using HTTP Port 5825.

By default, upon connection with the receiver, a Username and Password is required.  The username is ‘admin’ and the password is ‘password’.

The default setting of the receiver is to use DHCP.  Using DHCP enables the receiver to automatically obtain the IP address, Netmask, Broadcast, Gateway, and DNS address from the network.

How do I make a connection using Windows 7 to Trimble InTech OEM Receiver on an evaluation board?

15.

How do I monitor the position quality of the BD9xx receiver?

Position quality indicators are typically one or more of the following parameters:
• Position Type (RTK Fixed, RTK Float, etc…)
• Position Solution (3D, 2D, etc…)
• Age of Corrections (20 second timeout by default)
• Sigma Error Estimates (East, North, Up)
• Satellites Used / Tracked
• RAIM / FDE Status
• Velocity
• DOP’s (Dilution of Precision)
• SV Signal Strength (C/No dB-Hz)

Each of these indicators can be monitored by:
NMEA / PTNL ASCII Protocol
GSOF Binary Protocol
RT17/RT27 (57h) Binary Protocol
Web Interface Menus

The following table illustrates the methods these parameters can be monitored:
