Control Via Telnet Commands
To control the RS 500 in an automation
network, you will need nerves of steel,
and a controller that can send and receive
telnet commands and responses.
The command and response structures
of the controls provided via telnet are
in simple human language.
Power on
is
simply “power1” followed by a carriage
return to end the command. Command
feedback is confirmed by an echo of
the command, followed by a carriage
return, then another statement of “01”
followed by the command string, then a
carriage return and a line feed to end the
response string. If there is a value-change
like volume up, then the confirmation
response will include the new value at the
end of the string.
Telnet Session Length
:
Sending a command to the RS 500 opens
a telnet session – nothing tricky, just
send it a command and it will respond.
The session will remain open for 4 hours,
and then close. If another command is
received within that 4 hours, then the
clock restarts. The session will close 4
hours from the time of the last command
received. If your automation system treats
such activity as dropping off the network,
then pinging it in the early AM every day is
probably a good practice.
Control Command Examples:
Increment volume by 1 where volume
before the command is 51:
Command Z1vol+<CR>
Response: Z1vol+<CR>
01Z1vol52<CR><LF>
To mute:
Command: Z1mute<CR>
Response: Z1mute<CR>
01Z1mute<CR><LF>
Note:
Queries like ZONEON<CR> return a 1
for on and 0(zero) for off. If you query
ZONEOFF<CR> then the response will be
0 (zero) for on and 1 for off.
