Section 5: Operation
The Pegasus communicates with a computer or Weather Display
console via wireless interface. The Control Module has two ports
available on the back panel (RJ-11 jacks).
RS-232 Modem serial port
This is the main serial port in the system. It is usually connected to
the radio transceiver for communication with a computer or a
Weather Display.
RS-232 Aux serial port
This is a secondary serial port. It is usually used for direct
communication with a computer or a Palm device.
Communication
Normally the weather software or the Weather Display is used for
monitoring. Configuration is done through the menu selection of the
software or the display console.
The commands described in this section are used when the user
wishes to communicate directly with the system using a “terminal”
software program such as Hyper Terminal (available with Windows
operating systems).
The protocol for both serial ports is the following:
Bits per Second (baud rate): 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
All commands must be entered using upper case letters and
followed by a carriage return.
The weather station will return "ok" after the results of each
command. If the command is incorrect, the weather station will
return "?".
