Morse Code Messages
Homer produces sounds on Server programs start and termination. The sound may be a melody or a Morse code
message.
If there is no error preventing Server from running, a server identification message is played in Morse code on
Server start. The message identifies the running Server and its communication mode.
On Server termination, a melody (downward musical scale) is played.
In case of error, the message depends on the Server version.
Server versions V53 and less:
In case of error, the startup identification message is not played and the Server terminates immediately, playing first
the melody, then twice an error message, identifying the error due to which the Server is forced to terminate.
Following this, file transfer server SrvDld.exe is started (one long beep – Morse code for T).
Server versions V54 and more:
Server identifies the first of the errors that occurred by playing the corresponding error message (see below),
followed by a standard server identification message. Server does not terminate but sets itself in a “low-profile”
mode with reduced command set, which does not allow measurements or motor movements, but essentially only file
transfers so that you are able to remedy the situation that caused the error(s).
Server Identification Messages
Message
RS
RSA
Nxx
T
Description
Error Messages
SrvHo.exe Server in RS232 (or RS422) communication mode; results transmitted in
binary format
SrvHo.exe Server in RS232 (or RS422) communication mode; results transmitted in
ASCII format
SrvHo.exe Server in CAN Bus communication mode; xx, which may be 1 to 20, stands
for Homer CAN address (only relevant for MultiCAN network)
SrvDld.exe file transfer Server: only in RS232 (or RS422) communication mode
Morse codes other than those above represent error messages, forcing Server to either terminate or work in the
reduced mode. Error messages are played twice.
