1. Overview
1-1. Introduction
The projector is remotely controllable over RS-232C as well as Ethernet. It is useful for setting up the
projector away from the operator.
This protocol manual describes the specifications such as packet format and procedures for controlling the
projector.
In the following sections below, the term “CONTROLLER” is used as a device which controls the projec-
tor. CONTROLLER can be a PC or other specific device that is able to handle RS-232C or Ethernet.
Although most of commands are available for both RS-232C and Ethernet, some commands are dedicated
to Ethernet.
*Ethernet is a registered trademark of Xerox Corporation.
1-2. Glossary of Terms
Table 1-1 Glossary of Terms
Terms Abbreviated Description
CONTROLLER _Command initiator such as PCs.
PROJECTOR _Front projector.
SDAP Simple Display Advertisement Protocol Protocol name for advertising the projector status over
Ethernet.
SDCP Simple Display Control Protocol Protocol name for controlling projector over Ethernet.
PJLink _Protocol name for controlling projector over Ethernet.
1-3. Protocol Stack Structure
The protocol stack structure diagram is shown below. Though the stack is drawn for RS-232C and Ether-
net separately, the following portions are common.
Table 1-2 Common Portions in Protocol Stack
Layer Name Description
Sub Command Value is assigned for projector’s functions. Refer to the section 2-1 for detail description.
Simplified Command Packet format for sending/receiving “Sub Command”. Refer to the section 3-6-1 for detail
description.

(1) RS-232C
Fig. 1-1 RS-232C Protocol Stack
“RS-232C” layer is physical portion and “Asynchronous” is the traditional protocol layer as shown in the
section 3-2.
(2) Ethernet
Fig. 1-2 Ethernet Protocol Stack
Ethernet corresponding model
VPL-SX125, VPL-SW125
Because of traditional portions for Ethernet general layer, “TCP/IP”, “UDP/IP” and “HTTP” are out of
scope in this document.
SDCP specific command is described in the section 4-3-2.
SDAP and SDCP (PJ Talk) are SONY original protocol stack, which are described in the sections 4-3-1
and 4-3-3 respectively.

Sub Command is the value which is used by Simplified Command. Value is assigned for executing func-
tion. For example, if you want to change the picture mode, the appropriate value assigned for the desired
picture mode should be chosen.
