■3-pin Terminal block RS-232C ports
Fix RS-232C cable to the attached 3-pin terminal block, and then connect it to the MSD.
AWG28 to AWG16 conductor gauge is recommended. The recommended wire strip length is 7 mm/0.28 inch.
If it is connected to a D-sub9 pin, cut RTS, CTS, DTR, and DSR (unused) as needed.

2.1.3 Setting up RS-232C communication
(1) Connect the MSD and the control device via an RS-232C cable.
(2) Set the RS-232C communication as follows:
・RS-232C communication: baud rate, data bit length, parity check, and stop bit
・Operation mode of RS-232C communication: “RECEIVER”
【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 MSD in order to check the control status of
the MSD.

2.2.4 The number of TCP-IP connections
The MSD series can connect up to eight connections (eight ports) simultaneously. If the MSD is controlled
from nine or more PCs, they may not be connected to the MSD 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, MSD’s ports are occupied or
released so that nine or more connections can be connected logically.
[Table 2.4] Increasing connections
Your PC software
MSD
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 MSD for 30 seconds, the MSD 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 MDS is eight, ports are occupied permanently if the PC is turned off while
connections are valid. To prevent this, the MSD 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.
: 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: @SOT,1
@ERR,1
■Using as HELP:
If only delimiter is sent, command list as the help command is returned.
Example:
--------------- HELP (1/13) ---------------
(CHANNEL SELECT Command)
@SSW / @GSW : Set/Get Input Channel
@SSV / @GSV : Set/Get Video Input Channel
@SSA / @GSA : Set/Get Audio Input Channel
--------------- HELP (2/13) ---------------
(OUTPUT TIMING Command)
@SOT / @GOT / @GTD : Set/Get Output Timing
@SUM / @GUM : Set/Get Monitor Aspect
@SAP / @GAP : Set/Get Aspect
@SAR / @GAR : Set/Get Aspect Restore Mode
