Description of Arguments
Command or
(Note that all arguments are ASCII numeric codes from 48 to 57)
Query
10 bytes Query only.
Applies to MultiStream Mode. Returns the minimum data rate of the modem, in the form xxxxxx.xxx.
In MultiStream mode, the minimum data rate calc is EDR + MDR=ADR where:
MDR=(PIIC1 + PIIC2) * 1.015 for Normal Frames
MDR=(PIIC1 + PIIC2) * 1.05 for Short Frames
In non-MultiStream mode (Ethernet Only): MDR=ADR
In non-MultiStream mode (Assume PIIC 1 G703-E3): MDR=ADR
10 bytes Query only.
Applies to MultiStream Mode. Returns the Ethernet data rate of the modem in the form xxxxxx.xxx.
In MultiStream mode, the Ethernet data rate calc is EDR=ADR - MDR
In non-Multistream mode (Ethernet only): EDR=ADR.
In non-MultiStream mode (G703-E3): EDR=00000.000 kbps
10 bytes Query only.
Applies to MultiStream Mode. Returns the total or aggregate data rate of the modem (which is the same as the Tx
Data Rate) in the form xxxxxx.xxx.
In MultiStream mode, the aggregate data rate calc is ADR=EDR+ MDR
In non-Multistream mode (Ethernet only): ADR=EDR.
In non-MultiStream mode (G703-E3): EDR=00000.000 kbps
1 byte, value of 0 Command or Query.
thru 4 Sets or returns the user's Local/Remote status in the form x, where:
0=Local
1=Serial Remote (RS-232/RS-485)
2=reserved
3=Ethernet Remote
4=Ethernet plus Serial (DEFAULT)
EXAMPLE: <0/LRS=0 (selects Local)
1 byte, value of 0 Command or Query.
thru 2 Sets or returns the modem's NetSpec, in the form x, where:
0=DVB-S2
1=DVB-S2-EB1
2=DVB-S2-EB2
3=DVB-S2X
EXAMPLE: <0/NET=0 (selects DVB-S2)
1 byte, value of 0- Command or Query.
3 Sets or returns the modem's Operating Mode, in the form x, where:
0=Normal
1=MEO Hub TxRx
2=MEO Remote TxRx
3=MEO RxOnly
EXAMPLE: <0/OPM=0 (selects Normal)
