Getting Started
The following sections describe how to launch the RGA program and start acquiring data from the RGA
Head.
Note:
For detailed information and command description of the RGA program please refer to the RGA
On-Line Help files provided with the program disks. The RGA help system includes current and
detailed description of all the features, procedures and commands available in the program.
Starting the RGA Software
To start the RGA software simply double-click on the RGA icon in the "SRS" program
group created by the RGA installation program. You may also type the full path name
of the RGA program in the Run command from the Program manager.
You can only run one copy of RGA at the same time. If you attempt to start another
copy of RGA while it is already running, the existing copy is activated and brought to the
front of the screen.
Connecting to a Head
Connecting to an SRS RGA Head requires an available RS232 port on your PC and a full
DB9-DB9 RS232 cable.
To connect to an RGA Head do the following:
1. Connect the RS232 cable to the DB9 connector on the Head labeled
"RS232/DCE/28.8k.Baud".
2. Connect the other end of the cable to the RS232 port on the PC side (computer or
serial adapter).
3. Turn On the SRS RGA Head.
4. Start MS Windows and the RGA Program.
5. Select Connector List Setup from the Head menu or click the shortcut button (the
RS232 button).
6. Select the port to which the RGA head is connected from the connector column.
7. Press the Connect button.
The connection is made when “connected” is displayed in the status column, the RS232
button is checked, the toolbar GO button turns green, and the Scan and Head menu
commands get enabled.
