SATLNB LNB LN
Gets and sets parameters for the satellite lnb power.
Form:
Command Handler: SYSD
SATLNB|LNB|LN [TUNER INDEX] [KEY] [VALUE]
[TUNER INDEX]: 0 or 1, this is the tuner index that the key/value applies to.
[KEY]: Possible values for [KEY]
Terse Verbose Description
0 ENABLE This control will either enable or disable the DC
power supply that is used to provide power to the LNB. (newtec, pc88 ONLY)
1 POLARITY This control is primarily used in “Universal” LNB
applications. The LNB Polarity control allows for LNB
polarization selection; the 13VDC source will select
the Vertical polarity and the 18VDC source will select
the horizontal polarity. For typical “C” and “Ku” band
applications, the 18 VDC option is recommended.
2 TONE This control is used only for Universal LNB applications.
A universal LNB can route the high or low band from either
polarity to the IRD. The high band is selected by enabling
the 22 kHz tone and the low band is selected when the 0 Hz
tone is enabled.
3 CURRENT (Only applies to pc88 device)
6 DEVICE Device type (Read-Only)
[VALUE]: Possible values for [VALUE]
Terse Verbose Description
0 OFF ENABLE (newtec, pc88 ONLY)
1 ON ENABLE (newtec, pc88 ONLY)
0 H POLARITY Horizontal
1 V POLARITY Vertical
2 H+ POLARITY Horizontal Plus (pc88 ONLY)
3 V+ POLARITY Vertical Plus (pc88 ONLY)
4 OFF POLARITY Off (newtec, teamcast ONLY)
0 0KHZ TONE
1 22KHZ TONE
0 425mA CURRENT (pc88 ONLY)
1 775mA CURRENT (pc88 ONLY)
0 NEWTEC DEVICE (Read-Only)
1 PC88 DEVICE (Read-Only)
Response:
SATLNB RESPONSE
Verbose- "OK\r\n" to acknowledge receipt of command, or
"ERROR- [Description]\r\n" if error, ending command
Terse- "0\r\n" to acknowledge receipt of command, or
"[NON-ZERO NUMERIC VALUE]\r\n" if error, ending command
"\r\n" concludes modify responses (empty line)
Examples:
Get all settings for both tuners. Note that this example is with the PC88 device:
*.SYSD SATLNB
OK
DEVICE= PC88
Tuner[0]:
ENABLE= OFF
POLARITY= H
TONE= 0KHZ
CURRENT= 425mA
Tuner[1]:
ENABLE= OFF
POLARITY= H
TONE= 0KHZ
CURRENT= 425mA
Set tuner 0 ENABLE to ON:
*.SYSD SATLNB 0 ENABLE ON
OK
Get all settings for both tuners (terse). The order of variables is [DEVICE] [Tuner 0 settings, 3 in this case] [Tuner 1 settings].
With the PC88 device, each tuner will have an extra setting (CURRENT). This behaviour (device specific output) is similar to the
verbose command.
*.SYSD LN
0
0 1 0 0 0 0 0
Notes:
The output is based on the device. Some settings are only applicable to the PC88 board, so when the set device is NEWTEC, the PC88
Parameters are not displayed. Likewise these parameters can not be set when the NEWTEC board is installed.
For Newtec devices, polarity and tone cannot be set while enable is off.
