1892 1335 - Orion Radio Modem Operating Instructions - v2.9 / Aug 2009 43
Click on the COM port listed at the top left-hand corner to which you have connected the
Orion, e.g. COM1. This should establish contact with the Orion, and the window appearance
should change, with the message Modem Connected displayed. The unit’s details are
uploaded to the GUI and some are displayed.
Note that this overwrites any details that are currently held by the GUI.
Figure 14 - Orion connected
v The main reason for failure to connect to an Orion is that your terminal
equipment is not set to the same protocols as the serial port which it is
connected to (default 38400bps, no parity).
If the message Modem connected does not appear immediately, select the correct baud rate
and parity, then click the COMn radio button again (even if it is already selected). The
message Modem connected appears when the connection is established.
Depending on current settings, an extra set of tabs may appear at the bottom of the window.
These are related to telemetry functions, and are explained later in this manual.
Nothing is written from the GUI to the Orion until you explicitly write it using the menu command
Link > Write Parameters. This writes to the non-volatile memory and, with the exception of
serial link parameters, all changes come immediately into force.
To disconnect from the Orion, click the DISC button.
To close the GUI, select File > Exit or press Ctrl+Q.
