TSAT 3000 - Telemetry and data transfer via SATellite
TSAT 3000 Configuration Parameter Description, January 2013 Page 103 of 124
3.13.5 POW_LISTEN_HPA_ON
Ver <= 31.0.1: Default 0, Range 0… 255
Ver >= 31.1.0: Default 0, Range 0…2000
Ver <= 31.0.1
Not Used.
Ver >= 31.1.0
HUB: Not Used.
RT: Controls LISTEN mode operation.
Value Description
0
Set BUC ON – Send packet immediately (i.e. wait
MAC_TIMESLOT_MARGIN u-sec).
10 MHz settle time is defined to be 790 micro-sec for Zinwell 2W Ku-band BUC.
Therefore, recommended value is 0 when
POW_LISTEN_HPA_MODE is 1.
1 … 10 Set BUC ON – Wait specified number of slots – Then send packet to HUB.
11 … 2000
Set BUC ON – Wait specified number of millisec
(round-up to nearest slot) – Then
send packet to HUB.
Power settle time is defined to be 47.2 ms for Zinwell 2W Ku-band BUC.
Therefore, recommended value is 50 ms when
POW_LISTEN_HPA_MODE is 2 or 3.
Note 1: When PPR (Pulse Position Reservation –
PHL_SLOT_PHASE_MODE) is enabled, at
least one
of the RTs in the network should have both POW_LISTEN_HPA_ON and
POW_LISTEN_POLL = 0. That is to ensure that at least some POLL_ACK packets are sent
to HUB in slot-zero.
Note 2: POW_LISTEN_HPA_ON should be zero when HUB Ver <= 31.0.1.
Note 3: POW_LISTEN_HPA_ON has now effect when POW_LISTEN_HPA_MODE is zero.
3.13.6 POW_LISTEN_HPA_OFF
Ver <= 31.0.1: Default 0, Range 0… 255
Ver >= 31.1.0: Default 0, Range 0…20000
Ver <= 31.0.1
Not Used.
Ver >= 31.1.0
HUB: Not Used.
RT: Controls LISTEN mode operation.
Value Description
0
Wait 2 slots – Then turn BUC OFF.
Recommended value is 0 when
POW_LISTEN_HPA_MODE is 1.
1 … 10 Wait specified number of slots (minimum 2) – Then turn BUC OFF
11 … 20.000
Wait specified number of millisec
(round-up to nearest slot, minimum 2) – Then
turn BUC OFF.
Note:
POW_LISTEN_HPA_OFF has now effect when POW_LISTEN_HPA_MODE is zero.
