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 10 “COMMANDS”. Using an external CONTROLLER or SWITCHER, 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.

Calculate the actual 6Data length using the following method.
Calculate the Total Data Length using the B15 and B16 Data.
<Example>
If B15 = 02 h and B16 = 7 Fh, calculate the Total Data Size as follows.

5. BASIC OPERATIONS
5-1. COMMON OPERATIONS OF RS-232C/422A
RS-232C and RS-422A use the same port. Transmission and reception are performed only for the TX line
and RX line in the case of softwares using the same commands (based on the software conditions).
Handshaking normally established by RS-232C is therefore not performed.
5-2. PJ COM OPERATIONS
PJ COM is a port specially developed for projector based on RS-485. It therefore has no compatibility
with the commercially available RS-485. (Special uses only)
PJ COM is a half duplex communication composed of the data line and control line. The control line is
normally called as busy line, indicating whether the PJ COM line is available for use. Transmission is
performed only when this line is free. If in use, data is transmitted to the Data line.
5-3. BASIC OPERATIONS
Transmission and reception by RS-232C/422A and PJ COM are performed using the same protocols. The
data received by RS-232C/422A is input to the unit once to confirm that there are no errors in the data,
and it is then transmitted to PJ COM again. Basic operations at PJ COM are the same. The data input to
the unit once is checked that there are no errors, and is transmitted to RS-232C/422A again. The unit
serves as a communication bridge.
