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.
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 SACD Standard RS-232 connection port is set to the follow­ing protocols:
9600 Baud 8 Data Bits 1 Stop Bit No Parity

RS-232 Status Feedback Description for the SACD Standard
RS-232 Status Block Descriptions for the SACD Standard
The SACD Standard reports its operational status by transmitting a block of status data via the RS-232 connector. 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.
