RS-232 Control Protocol -- May 2010Note: The Ayre DX-5 Universal A/V Engine comes with AyreLink connectors for systemcommunications. The advantage of AyreLink is that it utilizes opto-isolators to ensure that noground loops are formed, and that any RFI generated by the CPU in the system controller iscompletely isolated from the audio and video systems.To use an RS-232C controller link for wired system control, an external Ayre RS-232C-to-AyreLink adapter unit is required. The RS-232C port is configured as a DCE device using afemale 9-pin D-Sub type connector.RS-232 Pin Configuration:The pin out of the DX-5 RS-232C-to-AyreLink adapter unit port is as follows:Pin 2 3 5Signal TXD RXD GNDThis pin configuration allows a PC running a serial terminal program (such as HyperTerminal) tocommunicate with the player using a straight-through DB9 9-pin RS-232 serial cable. Do NOTuse a “Null-Modem” type cable for PC connection. For connection to a system controller (eg,Crestron, AMX), please refer to the documentation that comes with the controller.Communication Settings:Baud Rate Data Bits Parity Stop Bit Flow Control9600 8 None 1 NoneCommand Structure:Each command starts with a # sign (ASCII 0x23), followed by a 3-character command code. Ifthere are any parameters for the command, the parameters are given in text format, separatedby a space (ASCII 0x20) from the command code. The # character (ASCII 0x23) must neverappear in the parameters. A carriage return (ASCII 0x0D) indicates the end of the command.Each command must not exceed 25 bytes including the start of command and end of commandbytes.The illustration of the command structure is as the followings: |
