2.1.3 Setting up RS-232C communication
Follow the procedure below to set RS-232C communication between the IMP-400UHD and control devices.
(1) Connect the IMP-400UHD and the control device via an appropriate cable. (2) Set the RS-232C communication as follows:
・RS-232C communication: Baud rate, data bit length, parity check, and stop bit
【Reference: User’s Guide】
(3) For the control device, set the same values in the same way as RS-232C communication (baud rate, data
bit length, parity check, and stop bit) in step (2) above.
(4) Send a communication command from the control device to the IMP-400UHD in order to check the control
status of the IMP-400UHD.

2.2.3 Setting up LAN communication
Follow the procedure below to set LAN communication between the IMP-400UHD and control devices.
(1) Connect the IMP-400UHD and the control device via a LAN cable. (2) Set up LAN communication as follows:
・Set IP address and subnet mask ・TCP pot number: 23, 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
IMP-400UHD in step (2) above.
(4) Send a communication command from the control device to the IMP-400UHD in order to check the
control status of the IMP-400UHD.

2.2.4 The number of TCP-IP connections
The IMP-400UHD series can connect up to seven connections (seven ports) simultaneously. If the IMP-400UHD is controlled from eight or more PCs, they may not be connected to the IMP-400UHD, since the number of connections that can be used is limited.
If you use eight connections or more, execute TCP-IP connection/close every time the communication command is sent or received from the software of user’s side. It makes IMP-400UHD’s ports occupied or released so that eight or more connections can be connected logically.
[Table 2.3] Increasing connections
Your PC’s software
IMP-400UHD
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 IMP-400UHD for 30 seconds, the IMP-400UHD 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 IMP-400UHD is seven, ports are occupied permanently if the PC is turned off while connections are valid. To prevent this, the IMP-400UHD 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: @SSW,2
“,”( a comma, “2C” in hexadecimal) is indicated between a command and parameter and between two
parameters.
: delimiter CR LF (return+line feed, “0D” and “0A” in hex)
■ If there is an error:
An error command is returned if an undefined command or wrong parameter is included. Example:@SSW,5
@ERR,1
■ Using as HELP:
If only delimiter is sent, command list as the help command is returned.
Example:
--------------- HELP (1/8) --------------- (CHANNEL SELECT Command) @GSW / @SSW : Get/Set Input Channel @GCP / @IOS : Get/Set Input Channel
--------------- HELP (2/8) --------------- (INPUT SETTING Command) @GDT / @SDT : Get/Set Digital Input Signal Detect Time @GHE / @SHE : Get/Set HDCP Input Enable @GAU / @SAU : Get/Set Auto Switching On @GOF / @SOF : Get/Set Auto Switching Off
