1 Communication specifications

1.1 RS-232C Port

The MSD-804FD controls peripheral devices externally by serial communication with RS-232C connector.
Connect control devices such as computers and the MSD with a RS-232C cable, and then control the MSD
and acquire status using commands. For command character notations and RS-232C connector
configuration, see sections “2 ASCII codes” in this manual and “8.10 COM Ports” in Users Guide.

[Table 1.1] Spec of serial communication

1.2 LAN Port

The MSD-804FD controls peripheral devices externally using LAN. Connect control devices such as
computers and the MSD-804FD with LAN, and then control the MSD and acquire the status using commands.
For command character notations, see “2 ASCII code”. For control using commands, use ports 6000 to 6999,
1100, and 23. Connection will be disconnected if no communication for 30 seconds or longer after connection.
For LAN settings, refer to “8.11 LAN Settings” in the Users Manual.

Physical layer 10BASE-T (IEEE802.3i)/100Base-TX (IEEE802.3u)

Network layer ARP, IP, ICMP

Transport layer

Application layer HTTP, TELNET

Port used for command control: 23, 1100, 6000 to 6999
Port used for WEB browser control (HTTP): 80, 5000 to 5999

[Figure 1.2] LAN connector

1.2.1 The number of TCP-IP connections

The MSD-804FD can connect up to eight connections (eight ports) at a time. If the MSD is controlled from
nine or more computers, they may not be connected to the MSD.
For nine or more connections, use your software to establish and close TCP-IP connections for each sending
and receiving communication commands. By doing so, ports are occupied and released in the MSD side so
that logically eight or more connections (8 ports) can be connected.

MSD-804FD Users Guide (Command Guide)

Note: If any command is not sent from the computer side to the MSD for 30 seconds, it disconnects the

connection to avoid the limitation problem on the number of connections. As a result, connection needs to be
established again from the computer side after the current connection of the computer is disconnected. (As
the number of ports in the MDS-804FD is eight, if the computer is turned off while it is connected, ports are
occupied permanently. To prevent this, the connection is disconnected if no communication command is sent
from the computer side.)

Example of programing with Microsoft Visual Basic.NET 2008:
Acquiring the following three data using Button1_Click in line 105 and sending the communication command
to the MSD:

- “communication command to be sent” of TextBox1

- “target host” of TextBox2

- “port number” of TextBox3
In this example, the following programing is run to solve the data transmission delay occurred when
connection and close are performed repeatedly. This is correspondent to the lines 4, 5, 14, 15, 16 in the
programing example.

'Open the cliant
Private stClient As TcpClient 'client class
Private stns As System.Net.Sockets.NetworkStream 'Stream class
Private portNum As Integer 'Port number
Private hostName As String 'Host name

stClient = New System.Net.Sockets.TcpClient(hostName, portNum)
stClient.NoDelay = True 'Disable delay
stns = stClient.GetStream() 'Open stream

TcpClient.NoDelay: This disables the delay if send or receive buffer does not exceed the set size. The

specified value is “False”. The delay time can be reduced by changing the NoDelay
property.

3 Commands

3.1 Summary

MSD-804FD Users Guide (Command Guide)

A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), and parameters (one-byte numbers
no parameter is required. Processing is executed by sending a delimiter at the end of the command.

Example: @SSW,1,1

“,”( a comma, “2C” in hexadecimal) is indicated between a command and parameter and between two
parameters.

: A “delimiter” is CR+LF, ”0D+0A” in hexadecimal.

* Some commands contain parameters specifying ASCII codes.

1. Commands for changing settings of the MSD
Commands and parameters with a comma are sent. (For some commands, several parameters can be
specified or no parameter is required.) When a command is processed correctly, the received command
is sent back without any change.

Example: @SSW,1,1 ←Sent command

@SSW,1,1 ←Reply from the MSD

2. Commands for receiving settings of the MSD
Commands are sent.( For some commands, parameters are required.) When a command is executed
correctly, the current settings are sent back following the received command. (For some commands,
several parameters are sent back.)

*

). For some commands, several parameters can be specified or

Example: @GSW ←Sent command

@GSW,1,1,1,1,1,1 ←Reply from the MSD

3. Error commands
If there is an undefined command or wrong parameter, the error command and the error details (one-byte
number) are sent back.

Example: @SSW,1,4 ←Sent command (This example contains wrong parameter)

@ERR,1 ←Error command from the MSD

4. Help
If only delimiter is sent without specifying any command, the command list is sent back. (If you want to
receive the whole list of the all commands, send a delimiter for 13 times, since the list is divided into 13
parts.)

Example: ←Sent delimiter
