1. Introduction
This protocol manual describes the basic configuration and basic operations of various commands used for projector. Projector can be controlled using the commands in the List of Commands provided in
Section 9 “COMMANDS”. Using an external CONTROLLER , etc., inputs can be switched and the power can also be turned on and off. In the following paragraphs, “CONTROLLER” means an external device such as a PC which controls projector using these commands.

Note: CMD1 and CMD2 are assigned with different commands for each unit. Consequently, there is no compatibility of commands between units. For details of the commands, refer to the respective list of commands for the units. Since there is no index function of this unit, the receiver INDEX will be ignored even if the command is designated.

<RS-232C 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.

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 reception for only the TxD and RxD lines.
Therefore there is no handshake normally performed by RS-232C.

6. Communication Procedure
6-1. 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
CONTROLLER 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.
In some cases, CONTROLLER may receive data from DEVICE even though it has not sent a command.
(For example, during SYS setting, SIRCS command, and switcher information when switcher is selected.)
Note: When Sircs Direct Command (CMD1 = 17 hex) is sent, return data may not be returned in some cases.
6-2. Reading the Command Tables
The command tables can be found in Section 9 (page 11).
CMD1 indicates the command category. The ACK from the projector is returned attached with the command category sent from the controller. However, when errors of the communication line occur, 10 hex (COMMON) will be returned.
CMD2 indicates the command processing method and processing results. 00 hex (SET) is set when setting data from the controller to the projector or when requesting for data processing. 01 hex (GET) is set when acquiring data. 2 hex (RETURN) is set when returning the ACK of the command received from the projector to the controller and when attaching data. 03 hex (ACK) is set when returning only the processing results.
However, F0 hex (COMM NAK) is set when the command the projector receives from the controller has a communication line error or checksum inconsistency.
The top of each category indicates the meaning of the data.

7. Communication Rules
. When sending a command from CONTROLLER, the return data (CMD1 = 10 hex or CMD1 = each category value, CMD2 = 03 hex) 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.
The following lists the approximate waiting times for PROJECTOR to return the return data after
CONTROLLER sends the command.
. When a communication error occurs, PROJECTOR ignores the data received until now, and set into the reception standby state.
. For undefined commands or commends 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 INDEX specified SIRCS direct command (CMD1 = 17 hex) 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.)
