3.13 POWER PARAMETERS
Power-Save functions are implemented in Ver >= 31.1.0. By use of these functions, the RT may
save a lot of power. Typical example with 2W Zinwell Ku-band BUC:
• Normal operation: 1.78 A @ 24 V = 43 W
• Listen mode – 10MHz: 1.25 A @ 24 V = 30 W
• Listen mode – Power: 1.09 A @ 24 V = 26 W
• Sleep mode: 0.45 A @ 24 V = 11 W
LISTEN Mode
The BUC is normally turned OFF, and will be turned ON when RT has something to send. You can
select to turn off 10 MHz and/or Power to the BUC.
- Switching 10 MHz is fast (less than 1 ms), but RT will consume more power.
- Switching Power consume less power, but it take longer time (approx 50 ms – one or more slots)
to turn on the BUC. Also, turning Power on/off could make disturbance to the receiver, and RT will
normally receive 1 or 2 CRC errors when Power is turned ON. Sometimes also a single CRC error
when Power is turned OFF.
In addition, RT may be excluded from the normal circular polling scheme, to decrease the time BUC
has to be ON.
RT will consume maximal Power when BUC is turned ON. Therefore, total Power consumption will
be something between 26 and 43 W, depending on how much data that is sent from RT to HUB.
LISTEN mode is configured by the following MIB parameters:
- POW_LISTEN_HPA_MODE
-
POW_LISTEN_HPA_ON
-
POW_LISTEN_HPA_OFF
-
POW_LISTEN_POLL
SLEEP Mode
Power to BUC, LNB, TX-board and RX-board are turned OFF – Only Main-board is alive, and unit
(HUB or RT) consumes minimum Power (11 W). Sleep mode may be activated:
- by Connected Application (DTR or CTS input signals).
- at Regular Intervals.
- by NMS Operator.
SLEEP mode is configured by the following MIB parameters:
- POW_WAKEUP_FIRST_TIME
-
POW_WAKEUP_INTERVAL
-
POW_LINK_UP_DURATION
-
COM_SIGNAL_IN [n]
