SPOT-1 EMITTER SET-UP
SPOT-1 SET-UP OVERVIEW
When driving SPOT-1 with a carrier frequency operating
at 76.8 kHz, 95 kHz, or 250 kHz, SPOT-1 can be configured
to automatically turn off when no carrier frequency is
detected. SPOT-1 will turn on again when it detects the
appropriate carrier frequency. This feature conserves
energy and extends the life of the 72 emitter diodes.
If the transmitter is operating at a carrier frequency other
than 76.8 kHz, 95 kHz, or 250 kHz, jumper P5 has to be
set to the OFF position. This causes SPOT-1 to remain on
until its power is removed. If P5 is set to the OFF position,
jumpers P6 and P7 are removed from the circuit and can
be left in any position.
FACTORY SETTINGS ARE:
P5 - Carrier Detection On
P6 - 95 kHz Selected
P7 - 250 kHz Selected
JUMPER CONFIGURATION
(Refer to Figure 2.0)
Jumper P5
If the RF modulator is operating at 76.8 kHz, 95 kHz, or
250 kHz, move jumper P5 to the ON position. If the RF
modulator is operating at any other frequency, jumper P5
must be in the OFF position.
Jumper P6
If the RF modulator is operating at 76.8 kHz, move jumper
P6 to the 76.8 kHz position and P7 to the OFF position. If
the RF modulator is operating at 95 kHz, move jumper P6
to the 95 kHz position and P7 to the OFF position.
Jumper P7
If the RF modulator is operating at 250 kHz, move jumper
P7 to the 250 kHz position. P6 can be positioned either to
76.8 kHz or 95 kHz when operating at 250 kHz.
CAUTION: If the 250 kHz frequency is not used, be sure
to position the 250 kHz detector in the OFF position!
