NAMEPLATE ILLUMINATION JUMPER JP2
The nameplate LED illumination jumper JP2 is located behind the GSM module’s front fascia, as shown in Fig.7,
. To access the
jumper the fascia 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.
