NAMEPLATE ILLUMINATION JUMPER JP2
The nameplate LED illumination jumper JP2 is located behind the GSM module’s
front facia, shown in Fig.7,
. To access the jumper the facia must be removed
and the jumper can be adjusted as required. When JP2 is set in position A (upper
2 pins) the LED is set for bright illumination, when JP2 is set in position B (lower
2 pins) the LED is set for low illumination and if JP2 is completely removed this
will disable the nameplate LED’s, see Fig.8.
