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.

3. RS-232C (Except for VPL-DX125/VPL-DX145/VPL-DW125)
3-1. Connection
Communication is enabled by the use of a D-Sub 9 Pin cross (reverse) cable.
The pin assignment of D-Sub 9 Pin and D-Sub 25 Pin is as follows.
D-Sub 9 Pin D-Sub 25 Pin Name
Shell = FG 1 FG Grounding for safety protection or cable shield
3 2 TxD Transmission data
2 3 RxD Reception data
7 4 RTS Transmission request
8 5 CTS Transmission permission
6 6 DSR Data set ready
5 7 SG GND for signal
1 8 DCD Data channel signal carrier detection
4 20 DTR Data terminal ready
9 22 RI Calling display (Presence/absence of calling signal)
Pin numbers not indicated as D-Sub 25 Pin are not used.
Assured cable length: 15 m (However, assurance may not be applicable for some cables.)
The software for controlling the projector from a PC is intended for performing transmission and recep-
tion for only the TxD and RxD lines.
Therefore the handshake normally performed by RS-232C is not necessary.
3-2. Communication Specifications
.Full duplex communication channels (Flow control is not performed.)
.Start-stop synchronism system
.Baud rate: 38.4 kbps (Default)/19.2 kbps/9600 bps (bits per second)
n
The baud rate setting is able to be changed in the menu of service mode :
Device →Other →232C (38.4 k = 0/19.2 k = 1/9.6 k = 2).
.The bit configuration is defined as follows.
1 START Bit +8 DATA Bits +1 PARITY Bit +1 STOP Bit

3-3. Communication Procedure
3-3-1. Outline of Communication
All communication between CONTROLLER (PC, etc.) and DEVICE (PROJECTOR) is performed by the
command block format. Communication is started by the issue of a command at CONTROLLER and
ended when the return data is sent to CONTROLLER after DEVICE receives the command.
CONTROLLER is prohibited from sending several commands at one time. This means that after CON-
TROLLER sends one command, it cannot send other commands until DEVICE returns the return data.
DEVICE sends the return data after processing the command. The time from when CONTROLLER sends
the command until the return data is returned differs according to the contents of the command.
n
When SIRCS direct command is sent, return data is not sent.
3-4. Communication Rules
.When sending a command from CONTROLLER, the return data from PROJECTOR should be received
first before sending the next command. Even if the next command is sent before receiving the return
data, since PROJECTOR will not be able to receive that command, it does not return a response to
CONTROLLER. Consequently, no error code is also sent.
For detail of the waiting times for PROJECTOR to return the return data after CONTROLLER sends
the command, refer to the section 3-5.
.When a communication error occurs, PROJECTOR ignores the data received until now, and set into the
reception standby state.
.For undefined commands or commands determined as invalid by PROJECTOR, PROJECTOR will
send the “NAK” return data to CONTROLLER .
.Take note that when data is written when the input signal of PROJECTOR is unstable, that data (value)
will not be incorporated.
.When SIRCS direct command is transmitted, leave an interval of 45 msec until the next transmission. (Do
not return the return data (ACK, NAK) when the SIRCS direct command is received.)
.For POWER ON/OFF/TOGGLE of the SIRCS direct command, send the command twice when this
unit is in standby mode (Low) state.
3-5. Approximate Return Waiting Times
The await-return time is approx. 30 to 1000 msec.
n
This is the case, unless the communications are interfered anyway.

4-2. Communication Procedure
Communication sequence is shown below. SDCP commands must be issued by CONTROLLER and
PROJECTOR responses to it. On the other hand, SDAP commands are sent by PROJECTOR and have no
response from CONTROLLER.
Fig. 4-1 Command Sequence
It is prohibited that CONTROLLER send another command before receiving the response to the previous
command. Since PROJECTOR executes the command before sending the return data, CONTROLLER
must wait a while before receiving the response. The waiting time depends on not only the commands but
also network traffic.
CONTROLLER PROJECTOR
SDCP SET/GET Request
Response
(OK/NG)
The command is executed if it’s valid.
Then, the receive command is sent to
