there is no compatibility of commands between units. For details of the commands, refer

5. Connection
<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.
Pins 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.
tion 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.
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.
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.
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.)
(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.
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
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
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
However, F0 hex (COMM NAK) is set when the command the projector receives from the controller has
a communication line error or checksum inconsistency.
