All rights reserved Overview This document is designed for application developers who want to control the SACD Standard using an external computer-based device. The document contains five sections: 1 Connecting to the RS-232 Port, including the RS-232 connector diagram, and RS-232 Port Protocols, on page 4 2 RS-232 Commands, on page 5 3 RS-232 Status Feedback Description, on page 6 4 RS-232 Status Block Descriptions, showing how the SACD Standard reports operational status, on pages 6-7 5 RC-6 Commands, describing the codes used for controlling the SACD Standard via IR, on page 8 Krell SACD Standard Developer’s Reference Connecting to the RS-232 Port A 9-pin RS-232 port is located on the right-hand side of the SACD Standard 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 SACD Standard. Refer to the operating manual of your external computer-based device for instructions on connecting to the SACD Standard. WIRING THE MALE To wire the male connector, follow these steps: RS-232 PORT 1. Locate the pin numbers on the male connector plug CONNECTOR (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 block is configured as three 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 SACD Standard 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". SACD Standard 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. RS-232 Status Block Descriptions for the SACD Standard All numeric values described in the following charts are decimal values unless otherwise noted. The description of the three 8-bit words follow.
