1. Introduction
This is the manual to control the projector from the network (LAN) using the PJ Talk.
2. PJCP
This manual describes the PJCP (Projector Control Protocol) that the PJ Talk supports.
2-1. Communication Procedure
Network version 1 does not support the user authentication. Therefore, the TCP connection can be opened
immediately and command can also be sent immediately. The desired port number can be specified.
(Default port number is 53484.) For setting the projector port number, refer to Section 3-2-2.

2-1-1. Time-out Processing
Connection
The PJ Talk closes the connection if it does not receive any command for a set time. Duration of the time-
out is 60 seconds.
ACK
If ACK is not returned within 30 seconds or longer for the command that has been sent, the control
application executes the time-out processing and closes the connection with the PJ Talk.

2-2. Format
The PJCP is installed in the TCP. Datagram of the PJCP consists of the Internet (IP) header, the datagram
(TCP) header and the PJCP header. Construction of the PJCP headers is shown below. The PJCP header
is followed by the PJCP data.

1 Command is sent from the control application.
2 The PJ Talk sends the received command to PJ Comm.
3 The PJ Comm sends the command to the main CPU and receives the execution result.
If no response is returned for 30 seconds or more from the main CPU, the PJ Comm executes the
time-out processing.
4 The PJ Comm sends the received command to the PJ Talk.
5 The PJ Talk sends the execution result of the command.
2-3-1. Note on Installation
When using the control application, it must send the next command after receiving the response from the
PJ Talk for the previous command.

3. PJ Talk
The PJ Talk that is the network service of projector, is the application program that enables communica-
tion control of the projector from the network (LAN) that has been provided by RS-232C/485. Vendor
can create the control application easily in a short time by using the PJCP protocol (projector Control
Protocol) that is compatible with the existing RS-232C/485.

3-1. Features
This section describes the main features of the PJ Talk.
Remote control
The controls such as turning on/off the power and selecting inputs can be performed from a personal
computer or the control device at the remote location on the same LAN network.
PJCP
The PJCP uses the same format and command systems as those of the serial protocol of the VPL-FX50.
Port number
The desired port number can be used. Therefore, the port numbers that are unique to the SI vendor can be
supported.. Default is 53484.
