Meter Display
DIP switch 8 controls what the 5 LEDs on the daughter board display. The 5
LEDs can display Signal Strength or Ambient RF Energy. Refer to the diagram
above (on page 25) in order set the unit to display Signal Strength or Ambient RF
Energy.
Signal Strength Meter
When the unit is set to display signal strength, the LEDs will display the signal
strength of the last received transmission from a device with the same network
ID. Refer to the Signal Strength Meter diagram to see how the LEDs behave in
this mode. The signal strength can be used to make the user aware of poor
signal quality and determine a better location to mount the units.
Antenna Select
DIP switch 9 controls the antenna mode of the unit. Refer to the Antenna Select diagram (see page 25) to set the
Antenna Select DIP switch to the appropriate setting. The mode the unit should set to depends on the part number. The
SPX-5631 and SPX-5641 will have the antenna selection set correctly from the factory. When changing the Antenna
Select DIP Switch, the unit will need to be power cycled twice for the change to take effect.
Chip Antenna
The SPX-5631 should be be set to Chip Antenna setting at all times. The SPX-5631 does not include a dipole antenna
and will not function properly if the unit is set to the External Dipole Antenna setting.
External Dipole Antenna
The SPX-5641 should be set to the External Dipole Antenna setting at all times. The SPX-5641 will not be able
communicate over the full 10,000 foot range if the unit is set to the Chip Antenna setting.
Pairing
DIP switch 10 determines if the unit is in Pairing Mode. When DIP switch 10 is on, the unit will enter pairing mode (refer
to Pairing diagram above on page 25). The Central and Remote units will come paired from the factory. After pairing
mode is first entered, the radio will reboot. After one second, the LEDs display a “scanning” sequence (see diagram
below) indicating the radio is “looking” for another radio also in pairing mode.
Ambient RF Energy
When the unit is set to display ambient RF energy, the LEDs will display the ambient RF energy of the selected channel
regardless of network ID. A greater number of illuminated LEDs indicates less ambient RF energy. A lesser number of
LEDs illuminated indicates more ambient RF energy. Detecting the ambient RF energy can be used to find a channel
most suitable for operation.
Put another unit into Pairing Mode to establish a pair. Both units must be
set to the same channel and network ID to be paired. It is recommended
that the two units be near each other when pairing. Once another unit is
detected which is also in Pairing Mode, the LEDs will flicker, pause,
reset, and finally the 3 center LEDs will settle into a dim-to-bright-to-dim
pattern. This indicates pairing is successful. Pairing Mode can now be
switched off on both units for normal operation.
Cypress Suprex® RF Series - Radio Configuration (Continued)
The pairing function does not affect other units that have already been paired and are NOT in Pairing Mode. However, if
more than two units are put into Pairing Mode at the same time, the results will be arbitrary. The first two radios to
discover each other will be paired regardless of distance or signal strength.
