RCS10 Modem and Redundancy Control System

TM058 - Rev. 2.3

xvii

Demodulator Opcode <240CH>

Change Status Bytes <1> Alarm 5 to:

(Bit 0 = Trellis Decoder Lock, Bit 1 = FM DSP Lock Mask, Bit 2 = T1 signaling fault, Bit 3 = Turbo Codec
lock fault, Bits 4 – 7 = Spares)

Add to the end of Status Bytes:

<1> Spare
<4> Symbol Rate

(Binary Value, 1bps steps)


Demodulator Opcode <2409H>

Change <2> Sweep Delay to:

(Binary value, 0.1 second steps. Reserved)


Change <1> Convolutional Decoder (18 =… to:

18 = Trellis 8/9 Rate, 19 = Comstream SEQ 3/4 rate 20 = TPC.793 2D, 21 = TPC.495 3D, 22 = TPC.325 3D)

Change <1> Alarm 5 Masks to:

(Bit 0 = Trellis Decoder Lock, Bit 1 = FM DSP Lock Mask, Bit 2 = T1 signaling fault, Bit 3 = Turbo Codec
lock fault, Bits 4 – 7 = Spares)

Demodulator Opcode <2A08H>

Change <1> Convolutional Decoder (18 =… to:

18 = Trellis 8/9 Rate, 19 = Comstream SEQ 3/4 rate 20 = TPC.793 2D, 21 = TPC.495 3D, 22 = TPC.325 3D)

Add to the end of Demodulator Opcodes:

Opcode: <2C0BH>

Command modem terminal emulation

<1>

Emulation Mode

(0 = Add viewpoint, 1 = VT 100, 2 = WYSE50)


Opcode: <2C0CH>

Command modem terminal baud rate

<1>

Baud Rate

(0 = 300 baud, 1 = 600 baud, 2 = 1200 baud, 3 = 2400 baud, 4 = 800 baud, 5 =

9600 baud, 6 = 19200 baud, 7 = 38400 baud)

Opcode: <2C0DH>

Command modem configuration copy

<1>

Source Configuration

(0 = current, 1 = configuration 1, 2 = configuration 2, 3 =

configuration 3, 4 = configuration 4, 5 = configuration 5)

<1>

Destination Configuration

(0 = current, 1 = configuration 1, 2 = configuration 2, 3 =

configuration 3, 4 = configuration 4, 5 = configuration 5)

Note: Source and destination configuration configurations must be different. Error 0x441 will be
returned if they are the same
