RS 232 Control

By far, the most accurate way to control or integrate the DTV-992 / 992 ULTRA into a home theater system is by RS 232 control. In this section, you will find hardware configuration and how to format the control data, command strings and examples.

Hardware Configuration

Baud Rate is selectable between 8 rates at the projector up to 9600 Baud (9600 is default).

NOTE: Some automation systems may only use/require pins 3, 2, 5 be connected.

How to format the control data

Every command sent to the projector is a group of 9 bytes that is called a record. Even a simple ON command is sent as a record. Below is an explanation of the syn- tax of a record. It is not necessary to memorize the syntax since the next section contains a chart of strings that work with any DTV-992 / 992 ULTRA and can be entered directly into most automation systems to control all the functions of the pro- jector.
