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.
2. Communication Specifications
<RS-232C Communication Signal>
. Full duplex communication channels (Flow control not performed.)
. Start-stop synchronism system
. Baud rate: 38.4 kbps (bits per second)
. The bit configuration is defined as follows.
1 START Bit + 8 DATA Bits + 1 PARITY Bit + 1 STOP Bit
START D3D2D1D0
BIT
EVEN Parity.....Total number of “1”s from D0 to D7 is an even number.
D4 D5 D6 D7

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.
