FITTING THE VEDOGSM4G MODULE
Make sure the board on which you intend to
fit the module is not connected to the power
supply.
IMPORTANT: any operation involving the assembly
or disassembly of expansion modules must be
performed with all input power (from power supply
unit or battery) OFF, in order to avoid permanently
damaging the expansion module you intend to add
or remove, as well as the control panel board.
Insert the plastic spacers in the relevant holes.
Then, taking care to plug the module connector
into the control panel connector designated MOD5
correctly, apply sufficient pressure to engage the
spacers in the GSM expansion card and plug the
connector in almost completely.
Fig. 1
For the module to work,
at least one of the two
antennas must be connected
and fastened to
connector
ANT1.
Connecting the second antenna improves
performance in weak signal conditions.
The antennas must be positioned
perpendicular to one another!
Fasten the cable connector onto the gold-coloured
ANT1 connector on the VEDOGSM4G module.
If using the second antenna, proceed by fastening
the cable to the gold-coloured connector ANT2 on
the VEDOGSM4G module.
Fig. 2
It is important that each antenna is connected
correctly and tightened fully.
Antenna presence can only be detected using
the antennas supplied. In all other cases antenna
presence detection must be excluded from the GSM
dialler options.
