Opcode: <2626h>

Command a Modulator’s Async Terrestrial Interface Type

Note: Command <2626h> is only valid if an asynchronous interface card is installed. If
not, this command is ignored. Note: The following command will also turn the carrier off
to protect the satellite.

Opcode: <2631h>

Command a Modulator’s CTS Mode and Polarity

<1>

CTS Control

Bit 0 = Polarity

0 = Normal, 1 = Inverted

Bits 1 and 2 = Mode

0 = Always On (factory default)

1 = CTS reflects the state of the RTS Input

2 = CTS reflects CTS Level Remote Command

Bit 3 - 7 = Spares


Opcode: <2632h>

Command a Modulator’s CTS Level

Query Response

<1>

CTS Level

Bit 0 = Level

0 = Off, 1 = On – only valid if CTS Control Mode bits
are equal to “2”

Bits 1 - 7 = Spares
