3. Select the RTS/CTS handshaking checkbox (optionally).
It is strongly recommended that you select the RTS/CTS checkbox as this makes
data exchange between the receiver and computer more reliable. Prior to select-
ing this option, make sure that:
• RTS/CTS handshaking is supported both at the computer and at the receiver.
• The cable used allows RTS/CTS handshaking.
4. Press Connect.
Along with the above listed options, the user may need to adjust some of the settings in the
Program Settings panel. This panel includes the following three options:
• Passive mode
• Manual mode only
• Restore the receiver’s original baud rate on Disconnect
In Passive mode PC-CDU is not allowed to change any receiver parameters. Note that in this
mode PC-CDU will display in the main window only those satellites whose elevation angles are lar-
ger than the elevation mask specified by the parameter Terminal Elevation Mask (see
4.2.4.1). Once Passive mode is off, PC-CDU will automatically force Terminal Elevation
Mask to -90º. Therefore the user will be able to view in PC-CDU’s main window (see 4.1) all of
the satellites that are being tracked. It is important to remember that this setting (-90º) will be ef-
fective as long as the main window remains open. Note however that the original value of
Terminal Elevation Mask will not be lost in this case; once the main window is closed, PC-
CDU will automatically restore the original mask.
If Manual mode only is on, PC-CDU will perform as an input/output terminal, which allows the
user to send commands to and receive information from the receiver.
If the user has selected the checkbox Restore the receiver’s original baud rate on
Disconnect, PC-CDU will determine and save the receiver’s original baud rate and then restore
this setting automatically on disconnecting the receiver (by pressing the Disconnect menu
item).
3.1.2. ‘Internet Server’ Mode
When running PC-CDU in Internet Server mode, the user can configure a TPS receiver

to
perform as a
PC-CDU server
. Remote receivers (PC-CDU clients) can then access this PC-CDU-
server via the Internet

.
The parameters Port, Baud rate, Infrared port, RTS/CTS handshaking, Passive
mode and Manual mode serve the same purposes as in Direct mode (see 3.1.1). The other

It is assumed that the receiver is connected to your computer directly.

This version allows a TPS receiver configured as PC-CDU-server to be accessed by only one remote re-
ceiver (PC-CDU-client) at a time.
