                   For BDX Signs

Introduction
GSM Monitor for BDX Signs is designed to monitor and report the operating status of BDX Scrolling signs via
SMS (Short Message Service) of GSM cellular network.
A GSM Monitor services up to two BDX scrolling systems, i.e. a double-sided BDX scrolling sign requires only one
GSM Monitor.


Installation
The GSM Monitor can be installed inside BDX scrolling sign. The connections are as follows.




           Power Control
     1                       Connect to the main power of the Scrolling system, e.g. the 24V DC for SPDE.
          (Cont and Gnd)
               Power         Connect to the battery of the POPS (Power Off Post Settling) is POPS is fitted.

Installing SIM card
GSM Monitor requires a GSM SIM card to operate. Before installing the SIM card,
please test it on a GSM cellular phone and make sure the SIM card is activated,
SMS-enabled and not PIN protected.
To install the SIM card:
    Turn off the GSM Monitor;
    Press Eject button to take out the SIM card holder;
    Place the SIM card on the holder;
    Push the holder fully back in the original position.


Testing the GSM Monitor
After installing the SIM card, turn on the GSM Monitor. The red GSM indicator will be on and the green one
blinking. This should last approximately 10 to 15 seconds before the red indicator goes off and the green one starts
blinking at a 3 second interval.
If the red indicator stays on, it means the GSM Monitor is not successfully connected to the cellular network. Please
make sure:
    Cellular network is available and the SIM card is activated;
    The antenna is properly installed.


Programming the GSM Monitor
The GSM Monitor can be programmed via SMS. Simply use a cellular phone to sent command(s) followed by
parameters to the GSM Monitor.
