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 wiring is as follows.




             Power control    connected to the main power of the Scrolling system, e.g.
           (Cont and Gnd)     the 24V DC for SPDE.
                    Power     power supply of the GSM Monitor. Typically connected to
            (Pwr and Gnd)     the battery of the POPS (Power Off Post Settling) is POPS
                              is fitted.
         Side A connector:    connected to synchronisation port of the scrolling system.
         Side B connector:    connected to synchronisation port of the other scrolling
                              system in a double-sided sign.
          Side A indicator:   status indicator of the scrolling system.
          Side B indicator:   status indicator of the other scrolling system in a double-
                              sided sign.
          SIM CARD slot:      slot with a SIM card holder for installing the GSM SIM
                              card.
            Eject button:     push to eject the SIM card holder.
          GSM indicators:     indicators for the GSM network connection
          MCU indicators:     operation status of the GSM Monitor


The GSM Monitor is shipped with an antenna with an elbow SMA connector. The antenna
socket is wired from the GSM monitor box, and recommended to be fitted on side of the
scrolling sign. Please install the antenna before using the GSM Monitor.
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.
