2.2 LAN communication
2.2.1 LAN communication
The FDX can be controlled via LAN communication. Connect the FDX with a control device (such as PC) via
an LAN cable and use commands to control the FDX and acquire its status.
For command control, use ports 6000 to 6999 or 1100. If no command is sent for 30 seconds after connection
established, the connection will be disconnected.

2.2.2 LAN connector specification
LAN connector assignments are as follows.
Since Auto MDI/MDI-X that distinguishes and switches straight/cross cables automatically is supported, extra
care is not necessary to connect the FDX to PC, HUB or the like.

2.2.4 Limit on the number of TCP-IP connections and port overload management
The FDX’s maintenance port supports a maximum of eight simultaneous connections (eight logical ports).
To maintain optimal system accessibility, it is advisable to issue “port-open” and “port-close” commands
before and after command or query strings are issued. This approach enables eight or more control devices to
be effectively interfaced simultaneously and without concern for communication errors.
[Table 2.3] Increasing connections
Your PC software
FDX-08
TCP-IP connection →(1 port occupied)
Send command (@xxx) →
←The command (@xxx) replied
TCP-IP close →(1 port released)
Note:
If no command is sent from the PC side to the FDX for 30 seconds, the FDX automatically disconnects from
that device. As a result, connection needs to be established again from the PC side after connection of the PC
is disconnected. (Since the number of ports in the FDX is eight, ports are occupied permanently if the PC is
turned off while connections are valid. To prevent this, the FDX disconnects connections if no communication
command is sent from the PC side.)

3 Channel Configuration
3.1 Outline
An I/O board has four channels.
An output board has four channels or two channels (scan converter output board).
3.1.1 Channel of output board
・The channel numbers of scan converter output board are the first two channels only; the rest of two
channels cannot be set.
・In the configuration shown below, valid channels and invalid channels are as follows.
Digital scan converter output board: No.5 and 6 are valid; No.7 and 8 are not used.

4 Command
4.1 Summary
4.1.1 Regular command
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases) followed by parameters (one-byte numbers). For some commands, multiple parameter values can be
specified or parameters are not necessary. Processing is executed by sending a delimiter at the end of the
command.
Example: @SPM,2
“,”(a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (return+line feed, “0D” and “0A” in hex).
An error response is returned if an undefined command or inappropriate parameter is included.
Example: @SSW,1
@ERR,1
If only a delimiter is sent, a list of help commands is returned.
Example:
- HELP (1/8) - (CHANNEL SELECT Command)
@IOS : Input/Output Select
@GVA: Getting Cross Point Video and Audio
@IOV : Input/Output Video Select
