Connecting to the RS-232 Port

A 9-pin RS-232 port is located on the right-hand side of the Home Theater Standard 7.1 back panel. Make sure the clamping screws (or thumbscrews) securely fasten the connection cable from the external computer-based device to the RS-232 port on the Home Theater Standard 7.1.

Refer to the operating manual of your external computer-based device for instructions on connecting to the Home Theater Standard 7.1.

To wire the male connector, follow these steps:

1. Locate the pin numbers on the male connector plug (not shown).

2. Locate the pinout numbers on the female connector. (See Pinout Signal list below).

3. Wire the male connector, matching the pin numbers on the connector plug to the pinout numbers on the female connector. Only three signals are necessary: 2=Received Data, 3=Transmitted Data, and 5=Signal Ground.

The Home Theater Standard 7.1 RS-232 connection port is set to the following protocols:

RS-232 Status Feedback Description for the Home Theater Standard 7.1

RS-232 Status Block Descriptions for the Home Theater Standard 7.1

The Home Theater Standard 7.1 reports its operational status by transmitting a block of status data via the RS-232 connector. The block is configured as eighteen 8-bit words. The first and last word always contains hexadecimal code 55 to facilitate message framing and synchronization. When the data block is sent through an RS-232 port, each 8-bit word transmitted will also have 1 stop bit associated with it. The exact RS-232 protocol settings for both status and Home Theater Standard 7.1 control are as follows:

9600 Baud 8 Data Bits 1 Stop Bit No Parity

The feedback system is available only through the RS-232 connector. The status can be activated in two ways. The first is to ask for status to be sent by sending the RS-232 command code "STAZ". The second is to enable auto status by sending the RS-232 command code "ASTEZ". Once the auto status command is sent, the Home Theater Standard 7.1 will transmit a status block whenever the status changes. Auto status is disabled by sending the RS-232 command code "ASTDZ". Auto status remains enabled until AC power is removed or turned off. When AC power is reapplied, auto status is disabled.

19 3A 25 58 367A SET MODE

The SET MODE command allows the user to set a specific audio decode mode using RC 5 commands. The code is set by sending the unit the SET MODE command, then the two DIGIT commands which define the mode. These three commands must occur in sequence; any command sent after the SET MODE command, other than the DIGIT commands, causes the SET MODE sequence to be reset. Refer to the list of audio decode modes on page 20. Modes that do not apply to the current input stream are ignored.
