INSYS Modem 336/56k 4.1 (UL) Functions
5.10.2 Operation
After the message ”OK” (short low tone – short pause – short high tone), the
modem expects the input of the PIN.
If the modem recognizes the dial tone of a modem that wants to establish a
connection, it will immediately switch to data mode.
After the PIN was entered, the caller will receive a response or a confirmation
of his/her action:
“OK” short low tone – short pause – short high tone
(command executed)
“ERROR” long low tone (invalid command)
The following commands can be performed via the phone keys:
Key Meaning
0* Terminate connection.
1*x Control switch output 1:
x: 1 Set switch output 1
0 Reset switch output 1
Return: “OK”
2*x Control switch output 2:
x: 1 Set switch output 2
0 Reset switch output 2
Return: “OK”
3* Query of the two alarm inputs:
Both alarm inputs are output in succession.
After the “OK”, for each alarm input state a tone will occur. If the alarm input is set to
“HIGH”, a high long tone is output, and for the LOW state a low long tone.
HIGH high long tone
LOW low long tone
Note: If nothing is entered for more than 25 seconds, the modem will
automatically disconnect.
