3.1.2. Configuration Strings
Configuration strings for the R2D7 are segmented into 3 parts:
* V ;
As with operating instructions, the first character is the header. This is always the
asterisk (“*”).
Next is the setting for the R2D7. The following is a table of valid commands:
V Print Version (followed by mode: R = Radio, B = Bus)
R Radio Mode (put system 7 in Radio mode)
B Bus Mode (put system 7 in Bus mode)
Finally, the terminator is either a semi-colon or the “CR” character.
3.2. Response Strings
Although the RP-Bus is not bi-directional, the R2D7 does report status information
back to the sender. The following table describes the responses for each event in the
R2D7:
Event Response
Power On “version, X-on”
Terminator Received “LF” if good command
“U” if command was not understood
“CR” after command was relayed to controls
Buffer Overflow “O”
Buffer In Empty “XOn” (Ctrl+Q), but only if XOff was sent
Buffer Is Half-Full “XOff” (Ctrl+s)
