Laptop Setup for Telemetry Communications

To verify that the satellite is sending data to the Internet site, the HyperTerminal communications will need to be set up differently than when it is used for DataRAM communications. Refer to the Setting Up a HyperTerminal section for the basics.

At the 'Port Settings' box, click on the arrow beside 'Bits per second'. Choose '19200'.
Data Bits > 8.
Parity > none.
Stop Bits > 1.
Flow Control > none.
Click 'OK'.

Attach the RS-232 cable (gray nine-pin cable stored inside the Pelican case) from the modem to the laptop. The Hyper-Terminal window should show 'Connected' at the bottom of the laptop screen. The data displayed on the screen will show:

Rx[12Oct01 16:23:21|268.00]Sync(20* 90 01): Dplr -2800 Pwr -100 Ebno 18.5 0/50

Update ser stats

Received f_val = 58.900002

Look for the 'Last value' number displayed in the scrolling data. It should match the displayed concentration value on the DataRAM.

Disconnect the RS-232 cable and place it back in the case. If you do not obtain the data, contact MTDC for help.
