1 About this Guide
This guide explains communication commands for controlling the “DFS-01UHD”and “DFS-01HD”(hereafter
referred to as “DFS”, scan-converter equipped frame synchronizer.
■You can perform the following operations using communication commands.
・Setting I/O, audio, and EDID.
・Setting preset memory.

2.1.3 Setting up LAN communication
(1) Connect the DFS and the control device via a LAN cable.
(2) Set up LAN communication as follows:
・Set IP address and subnet mask
・TCP pot number: 1100, 6000 to 6999
【Reference: User’s Guide】
(3) Establish the connection from the control device to the IP address and TCP port that are set to the
DFS in step (2) above.
(4) Send a communication command from the control device to the MSD in order to check the control
status of the MSD.

2.1.4 The number of TCP-IP connections
The DFS series can connect up to eight connections (eight ports) simultaneously. If the DFS is controlled from
nine or more PCs, they may not be connected to the DFS normally, since the number of connections that can
be used is limited.
If you use nine connections or more, execute TCP-IP connection/close every time the communication
command is sent or received from the software of user’s side. By doing so, DFS’s ports are occupied or
released so that nine or more connections can be connected logically.
[Table 2.2] Increasing connections
Your PC software
DFS
TCP-IP connection
→
(Occupied by 1 port)
Send command (@xxx)
→
←
Send back command (@xxx)
TCP-IP close
→
(Release 1 port)
Note: If any command is not sent from the PC side to the DFS for 30 seconds, the DFS disconnects the
connection to avoid the limitation problem on the number of connections. As a result, connection needs to be
established again from the PC side after the current connection of the PC is disconnected.
(Since the number of ports in the DFS is eight, ports are occupied permanently if the PC is turned off while
connections are valid. To prevent this, the DFS disconnects connections if no communication command is
sent from the PC side.)

3 Command
3.1 Command outline
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), and parameters (one-byte numbers*). For some commands, several parameters can be specified or
no parameter is required. Processing is executed by sending a delimiter at the end of the command.
Example: @SPM,2
“,”( a comma, “2C” in hexadecimal) is indicated between a command and parameter and between two
parameters.
■If there is an error:
An error command is returned if an undefined command or wrong parameter is included.
Example: @SOT,1
@ERR,1
■Using as HELP
If only delimiter is sent, command list as the help command is returned.
