Notes:
•
In some GSM networks the unanswered calls are, after elapse of a certain time delay,
automatically transferred to the voice mailbox. If the "calling time" is longer than the call
transfer time, the control will not be performed. If this is the case, you should limit the
"calling time" so that the module can reset the connection by itself and perform the control.
•
In order to fully utilize the CLIP control idea and to control the outputs without paying the
charges for telephone connections, you should disable the voice mail function. Rejection of
a call with enabled voice mail service will divert it to the voice mailbox, the call being
counted as realized. The call charge is borne by the calling party.

OCAL CONTROL
9.2.1
Control by using module keys
During normal operation, pressing and holding one of the module’s push-buttons for the
duration of 1 second will result in enabling/disabling the output, the number of which
corresponds to the push-button’s number. The message on the output’s status is displayed
on the LCD display and the module simultaneously generates the sound signal identical to
that during remote control by DTMF signals. If the output is enabled permanently, it is
indicated on the LCD display by the "O" character, and if disabled – by the "o" character.
If the output is enabled for a specified time, the "O" character is blinking.
The following push–buttons are used for controlling the status of outputs or for
bypassing/unbypassing the inputs:
ESC – controlling OT1; bypassing
IN1
CHANGE
– controlling OT2; bypassing
IN2
NEXT – controlling OT3; bypassing
IN3
OK
– switching OFF all outputs; bypassing
IN4
The manual bypassing/unbypassing the inputs is also implemented by the GSM-4S module’s
push-buttons. Pressing one of these push-buttons three time will cause bypassing the input
of the number corresponding to the number of a given push-button (see: description of
module’s push-button). The bypass of this input will be confirmed on LCD display by
displaying character "b" in the field indicating the status of a given input, and by displaying
the INn bypassed message, where n = 1,2,3,4 corresponds to the input’s number. At the
same time three short beeps are generated. If this input has been already bypassed,
the execution of this operational sequence will result in unbypassing this input. Unbypassing
should be acknowledged by changing the indication of the input’s status, by displaying the
message “INn unbypassed” and by audible signals (four short and one long beeps).
The function of manually bypassing particular inputs can be disabled. To do so, deselect the
INn bps.manual. option, where n denotes the input number. The inputs can be manually
bypassed at all times.
9.2.2
Tone control from terminals R-1, T-1
In order to make possible bypassing/unbypassing the inputs and enabling/disabling the
outputs, you must program the module accordingly:
•
Enter the device service mode.
•
Using
the
IN1–4 bps.manual function, indicate the inputs to be bypassed/unbypassed
locally.
•
Using
the
Controllable out. function, indicate the outputs to be controlled locally.
•
Using
the
Control function, program a six-character control code to make possible
bypassing/unbypassing the inputs and enabling/disabling the outputs.
•
Hang up to exit the service mode.
