[COM3] if connected to COM3 port

Any of the above prompts indicate that the receiver is ready and waiting for command input. The

screen may display other port names for other port types, for example USB1, USB2, USB3 or AUX.

 1. You may also have to wait for output from receiver self tests. For example, on start-up,

the OEMV family receiver is set to log the RXSTATUSEVENTA log ONNEW on all

ports. See Section 7.4, RXSTATUSEVENT Log on Page 119 for more details.

2. If you find that CDU is unable to locate your OEMV family receiver, it may be that you

have previously used the SAVECONFIG command. In this case, try using a different

COM port to communicate to the receiver. Once communication has been established,

issue a FRESET STANDARD command. You should now be able to use your original

communication port again.

3. XCOM1, XCOM2 and XCOM3 virtual ports can be generated by the receiver. However they

are unlikely to appear as a port prompt as you cannot connect to these types of ports using

CDU. Also, they are not available with the COM command but may be used with other

commands, such as INTERFACEMODE and LOG. Refer to the OEMV Firmware Reference

Manual for the virtual ports available and details on the above mentioned logs.

Commands are typed at the interfacing computing device’s keypad or keyboard, and executed after

issuing a carriage return command which is usually the same as pressing the <Enter> key.

An example of a response to an input command is the FIX POSITION command. It can be as:

[COM2] fix position 51.11635 -114.0383 1048.2 [carriage return]

<OK

where

[COM2] is the port prompt, followed by the command you enter from your keypad or keyboard

and [carriage return] indicates that you should press the <Enter> key.

The above example illustrates command input to the base receiver’s COM2 port which sets the

position of the base station receiver for differential operation. Confirmation that the command was

actually accepted is the appearance of <OK.

If a command is entered incorrectly, the receiver responds with:

NVALID MESSAGE ID (or a more detailed message)

WARNING!: Ensure the Control Panel’s Power Settings on your PC are not set to go into

Hibernate or Standby modes. Data will be lost if one of these modes occurs

during a logging session.
