3.1.2Communicating Using a Remote Terminal

One method of communicating with the receiver is through a remote terminal. The receiver has been pre-wired to allow proper RS-232 interface with your data terminal. To communicate with the terminal the receiver only requires the RX, TX, and GND lines to be used. Handshaking is not required, although it can optionally be used. Ensure the terminal’s communications set-up matches the receiver’s RS-232 protocol. In the case of the DL-V3, Bluetooth and Ethernet are available.

3.1.3Communicating Using a Personal Computer

An IBM-compatible PC/laptop can be set up to emulate a remote terminal as well as provide the added flexibility of creating multiple-command batch files and data logging storage files. Any standard communications software package that emulates a terminal can be used to establish bidirectional communications with the receiver, for example, HyperTerminal or our own graphic user interface (GUI) program, CDU. All data is sent as raw 8-bit binary or ASCII characters.

3.2Getting Started

Included with your receiver are NovAtel’s CDU and Convert programs. CDU is a windows-based GUI which allows you to access the receiver's many features without the need for communications protocol or to write special software. The Convert utility is a windows-based utility that allows you to convert between file formats, and strips unwanted records for data file compilation. See the DL-V3 quick start guide or installation.

3.2.1Starting the Receiver

The receiver’s software resides in flash memory. When first powered, it undergoes a complete self- test. If an error condition is detected during a self-test, the self-test status word changes. This self-test status word can be viewed in the header of any data output log. Refer to the chapter on Messages in the OEMV Firmware Reference Manual for header information. If a persistent error develops, please contact your local NovAtel dealer first. If the problem is still unresolved, please contact NovAtel directly through on of the methods listed in the Customer Service section at the beginning of this manual on Page 20.

3.2.2Communicating with the Receiver Using CDU

Launch the CDU program and select Device Open from its main menu. The Open Configuration window appears. The example below shows an Open Configuration window with two possible configurations already set up. Your configurations may be different or you may have none at all, in which case, the Open Configuration window is empty.
