Mode Selector
REMOTE:
Local commands and indications are deactivated. Commands are only
executed when sent from the central unit.
OFF:
Internal relays are disabled. No commands, either remote- or local are
executed.
LOCAL
Local command buttons and LED indications are activated. Commands are
only executed when using the command buttons. Remote operation is
deactivated.
Communication is not affected by the position of the Mode Switch. It will therefore be
possible to send status requests and new configuration settings even if the Mode Switch is in
the OFF or Local position. Any change on the digital and analog status will also be sent back
to the central in OFF or Local position.
The Mode Switch must be in one of the three positions for more than 2 seconds before an
SMS is sent with the new position. E.g. if the Mode Switch is switched from REMOTE to
LOCAL, and the switch is in the OFF position less than 2 seconds, only the LOCAL position
message are sent.
Local Command buttons
The command buttons ‘Open’ and ‘Close’ are activated only when Mode Switch is in the
LOCAL mode. The buttons must be pressed more than 1 sec to execute the OPEN or CLOSE
command. The new status will be reported back to the central unit either as a SMS or CSD
connection dependent upon the configuration setting.
Hardware Setup
Preparing the SIM Card
The PIN code must be deactivated before inserting it in the SIM card socket. Insert it into a
cell-phone and follow the procedure explained in the cell-phone manual.
If the PIN code is activated when powering the ComTroll 333 RTU, the red ERROR LED will be
ON and the green NETWORK LED will flash. Normally, SIM cards can be provided without PIN
codes from the network operator.
Selecting the correct type of SIM card/subscription
We strongly recommend disabling voice feature on the SIM cards. Also, pre-paid SIM cards
should not be used for this application.
The SIM cards must be supporting CSD communication (GSM Data, 9600bps) and SMS. As the
telephone numbers are used as identification of the devices in the network, the Caller ID
(CLIP) service must be activated.
