Serial Control Protocol
The RDMS is controlled via a simple three-wire serial interface (transmit, receive, and ground). Configure your
controller’s serial port to the following settings:
•
Baud rate of 115,200
•
8 bits
•
No parity
•
1 stop bit
For setup and configuration via a standard Windows-based PC, Quasonix recommends the application called
Terminal
, a flexible, full-featured control interface that is included in the RDMS Product CD. Otherwise, one can
use other terminal emulators, such as PuTTY or TeraTerm.
When power is applied to the receiver, a welcome message, shown in Figure 5, displays. After the welcome
message, the mode status displays (in this example, PCM/FM). This varies depending on the modes and versions
loaded into the RDMS. Additional status information about RDMS initialization displays last. This also varies
depending on RDMS settings and options.

Figure 8
: RDMS™ Welcome Message Example
The base command syntax is “a command followed by zero or more command parameters
.
”
If the command is
issued with arguments, there must be a space after the alphabetic characters. The commands are not case sensitive.
All commands generate a response of one or more lines. The length of the response depends on the verbosity level.
The last response line is always the currently selected mode (PCM/FM, SOQPSK, CPM, or PSK), followed by the
character “+” or “>”, depending on the version of the firmware. This prompt signifies that the RDMS is ready to
accept new characters.
