28 SMART-AG User Manual Rev 2
Chapter 3 Operation
Refer to CDU’s Help file by selecting the Help | Contents menu. Ensure you can see the Console and
ASCII Messages windows by selecting them from the View menu.
When the receiver is first turned on, no data is transmitted from the COM ports except for the port
prompt. The Console window displays a port name:
[COM1] if connected to COM1 port,
or
[COM2] if connected to COM2 port,
Any of the above prompts indicate that the receiver is ready and waiting for command input.
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. Refer to the OEMV Family Firmware Reference Manual 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 the command FRESET STANDARD. You should now be able to use your original
communication port again.
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
