Ex:
TU is on CH3. RU #1 is on CH2. RU #2 is on CH1.
1. Press the Calibrate/Channel Switch for 5 seconds.
2. RU #1 and #2 both beep three times. All devices are now on CH3, and the Communication LEDs are
lit.
3. Press the Calibrate/Channel Switch for 0.5 second.
4. RU #1 and #2 both beep once. All devices are now on CH1.
5. Press the Calibrate/Channel Switch for 0.5 second.
6. RU #1 and #2 both beep twice. All devices are now on CH2.
7. Press the Calibrate/Channel Switch for 3 seconds.
8. RU #1 and #2 both beep twice. All devices are now programmed to CH2.
Note: While several RUs can be used with one TU, use of multiple TUs with a single RU is not guaranteed to
work, due to potential wireless communication interference.
5.5.4 RU
Power
Management
The RU shall be required to sync to any incoming message; therefore, significant power management is not
possible during the ‘active’ state.
To maximize battery life, an RU that has not received a transmission from the TU for 30 minutes shall enter a
power-saving mode:
possible during the ‘active’ state.
To maximize battery life, an RU that has not received a transmission from the TU for 30 minutes shall enter a
power-saving mode:
• The nRF905 shall be disabled.
• All indicators except the Power LED shall be disabled.
• The RU shall beep once every 20 seconds to denote the power-saving mode.
• All indicators except the Power LED shall be disabled.
• The RU shall beep once every 20 seconds to denote the power-saving mode.
Once the RU has entered this mode, it must be turned off and on again to return to normal operation.
5.5.5 TU
Power
Management
The TU shall implement full-time power management of the RF transmitter, its greatest power sink. The
nRF905 shall be disabled at the end of each transmission, reducing the power consumption by 80-90%.
Because of the minimal transmission rate of the TU (duty cycle ~1%), the RF system shall thus be in low-power
mode most of the time.
