Connecting to the RS-232 Port

WIRING THE MALE RS-232 PORT CONNECTOR

RS-232 PORT FEMALE CONNECTOR

Located on the back panel of the SACD Standard

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 thumb- screws) 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.
