Rotel RSP-976

RS232 HEX Protocol

The RS232 protocol structure for the RSP-976 is detailed below. This is a HEX

based communication protocol.

Connection Settings

Baud Rate Parity Valid Data Bits Stop Bit Value

Handshaking Data Type

2400 N 8 1 None String

All commands sent to the attached Rotel device must follow the command structure

detailed below, unless specified otherwise. Send only the bytes only, no spaces,

delimeter, etc.

Standard Command String Format

Start Count Device ID Type Key Checksum

0xFE 0x03 0xC0 0x10 0xXX 0xXX

Note: The count byte only includes the ID, Type, and Key bytes; it does not include the

Start or Checksum bytes.

Note 2: Do not include any carriage returns or line feeds after the commands

Communication Protocol

Command and response messages are included on the following pages. The

standard response string of the unit mirrors the data that would be available on the front

panel of the unit.

Any change to the status of the front display on the unit will prompt a feedback string

mirroring that change.

Note that the spaces shown between hex bytes below are for clarity only; do not include

spaces in the actual command sent to the unit.

Meta Encoding

The start byte for all command and response strings is FE. To keep the device

from encountering the start byte FE in any position other than as the start byte, any

occurrence of the byes FD or FE in a command string must be converted to either FD 00

(for FD), or FD 01 (for FE). This will allow the string to pass while masking any

occurrence of the byte FE except as the start byte. Commands that have Meta Encoding

applied will be highlighted in red.
