Response to Query

Minimum

Data Rate

(MultiStream

Mode)

N/A

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

N/A

MDR?

MDR=xxxxxx.xxx

(see Description of

Arguments)

Ethernet

Data Rate

(MultiStream

Mode)

N/A

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

N/A

EDR?

EDR=xxxxxx.xxx

(see Description of

Arguments)

Total or

Aggregate

Data Rate

(MultiStream

Mode)

N/A

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

N/A

ADR?

ADR=xxxxxx.xxx

(see Description of

Arguments)

Local/Remot

e Status

LRS =

1 byte, value

of 0 thru 4

Command or Query.

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)

Arguments)

Network

Specification

NET =

1 byte, value

of 0 thru 2

Command or Query.

Sets or returns the modem’s NetSpec, in the form x, where:

0 = DVB-S2

1 = DVB-S2-EB1

2 = DVB-S2-EB2

EXAMPLE: <0/NET=0 (selects DVB-S2)

OPM =

1 byte, value

of 0-3

Command or Query.

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)
