Programming Interface and IR Remote Commands for No5101

Controlling the No5101 via RS232/NET

Introduction

This document describes the remote control protocol for controlling the No5101 via the RS232/NET interface. The No5101 implements virtual IR commands in order to simplify the protocol. Any operation that can be invoked using the IR remote control can be achieved over RS232 using the Simulate RC5 IR command (0x08). See page 05 for details of this command. The RC5 IR code set is listed on page 9
IP control is via port 50000 of the IP address of the unit (in the Network Settings menu).
Conventions

• All hexadecimal numbers begin 0x. A
• ny character in single quotes gives the ASCII equivalent of a hex value.
• represents an unknown or variable number.

Serial Cable Specification The cable is wired as a “straight-through” cable:

Data transfer format

• Transfer rate: 38,400bps.
• 1 start bit, 8 data bits, 1 stop bit, no parity, no flow control.

Command and response formats
Communication between the remote controller (RC) and the No5101 takes the form of sequences of bytes, with all commands and responses having the same basic format. The No5101 shall always respond to a received command but may also send messages at other times.
Each transmission by the RC is the following format:

• St (Start transmission): 0x21
• Zn (0x01): see below.
• Cc (Command code): the code for the command
• Dl (Data length): the number of data items following this item, excluding the ETR
• Data: the parameters for the command
• Et (End transmission): 0x0D

Each response by the No5101 is the following format::

• St (Start transmission): 0x21 `
• Zn (0x01): see below.
• Cc (Command code): the code for the command
• Ac (Answer code): see below.
• Dl (Data Length): the number of data items following this item, excluding the ETR
• Data: the parameters for the response of length n. n is limited to 255.
• Et (End transmission): 0x0D The No5101 responds to each command from the RC within three seconds.

The RC may send further commands before a previous command response has been received.
Zones
The following Zones are defined: 0x01 ­ Zone 1.
Answer codes
The following answer codes are defined:

• 0x00 ­ Status update.
• 0x82 ­Zone Invalid.
• 0x83 ­ Command not recognized.
• 0x84 ­ Parameter not recognized.
• 0x85 ­ Command invalid at this time.
• 0x86 ­ Invalid data length.

State changes as a result of other inputs
It is possible that the state of the No5101 may be changed as a result of user input via the front panel buttons or via the IR remote control. Any change resulting from these inputs is relayed to the RC using the appropriate message type.
For example, if the user advanced to the next chapter using the / button on the front panel, a Title/Chapter status message (defined below) would be sent to the RC. Similar action would be taken for all other state changes (including elapsed time).
Reserved Commands
Commands 0xF0 to 0xFF (inclusive) are reserved for test functions and should never be used.
Example command and response sequence
As an example, the command to simulate the RC5 command “20­53”, PLAY:

Assuming that the command was accepted by the player and is being processed, the No5101 responds to this command with the following sequence:

AMX DuetTM Support

The No5101 shall be fully compatible with AMX DuetTM Dynamic Device Discovery Protocol (DDDP) The following description of Dynamic Device Discovery comes from the AMX website (www.amx.com). Dynamic Device Discovery is part of AMX’s DuetTM platform, which combines the proven reliability and power of NetLinx with the extensive capabilities of the Java 2 Micro Edition (J2ME) platform. When integrating a serial or IP device from a manufacturer embedding the Dynamic Device Discovery Protocol (DDDP), Duet recognizes the device and loads the appropriate Duet module, which automatically installs the new device. AMX’s NetLinx Master can then find and install the Duet device module either from a library on the master, from AMX’s Web site, or from the manufacturer’s Web site. Duet also allows for device swapping so that programming changes are not required when devices with DDDP are removed or replaced ­ a huge benefit for end-users. The Duet platform is an extension of AMX’s InConcert® manufacturer partner program, which was developed to ensure seamless communication between partners’ devices and the AMX control system.
Data is specified in the ASCII format. All ASCII characters between the quotes “” should be recognized/transmitted. “r” is a carriage return (0x0D)
Command:…………………… “AMXr”
No5101 Response: “AMXB<Device-SDKClass=CD Player><Device-Make=Mark Levinson
