2.2.4 The number of TCP-IP connections
The FDX series can connect up to eight connections (eight ports) simultaneously. If the FDX is controlled from
nine or more PCs, they may not be connected to the FDX normally, since the number of connections that can
be used simultaneously is limited.
If you use nine connections or more, TCP-IP connection will be executed/closed every time the
communication command is sent or received from the software of user’s side. By doing so, FDX’s ports are
occupied or released so that nine or more connections can be connected logically.
[Table 2.3] Increasing connections
Your PC software
FDX-32
TCP-IP connection
→
(1 port occupied)
Send command (@xxx)
→
←
The command (@xxx) replied
TCP-IP close
→
(1 port released)
Note:If any command is not sent from the PC to the FDX for 30 seconds, the FDX 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 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.)

4Command
4.1 Command specification
The FDX can be controlled by regular command or compatible mode communication command.
4.1.1 Regular command
A command consists of “@” (“40” in hex), 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 hex) is used between a command and parameter and between two parameters.
: delimiter CR LF (return+line feed, “0D” and “0A” in hex)
An error command is returned if an undefined command or wrong 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: Get Cross Point Video and Audio
@IOV : Input/Output Video Select
@GCP: Get Cross Point Video
@IOA : Input/Output Audio Select

A command consists of one-byte alphabetical characters (upper and lower cases) and parameters (one-byte
numbers). Processing is executed by sending a delimiter at the end of the command.
Example: s,3
“,”( a comma, “2C” in hex) is used between a command and parameter and between two parameters.
: delimiter CR (return, “0D” in hex)
Example: wva
