What's LT200

LT200 is a PC-based digital I/O module that is designed to connect your devices and equipment. This solution allows a remote PC or Terminal to monitor, configure, manage, and send/receive data via the LAN or Internet. Users can use specific software or browser to view and control LT200, a product of web-based DIO control terminal.

LT200 is equipped with 8 Relay output (support up to AV250V/5A or DC30V/5A) and 8 Relay input. The input Relay module can option AC110/240V or DC24V, etc. It is one PS/2 keyboard, 10 Base-T (RJ-45) Ethernet and a RS232 port for user's usage. In addition, there are 18 LEDs (input x8, output x8, power x1, and LAN x1) outside the case for status display.

The dimension is 103(D)x210(W)x53(H) mm, and the whole system will only need a +5V/1.6A power adapter.

The kernel control board of LT200 is designed by ICOP Mity-mite 386SX-40MHz CPU module with 4MB memory onboard. ICOP integrates BIOS and DOS and control software, which program base on ICOP DSock - DOS TCP/IP library, into a 512k Flash chip.

Both source code of both control board and remote PC are open for programmer's reference. LT200 can be widely applied, depending on your requirement, as a security system in stores, offices, and public facilities; or as a monitor system to make any product check in factory.

Features

8 relay inputs and 8 replay outputs. Serial port to Ethernet function support. Support TCP command to send/receive I/O message. Support HTTP command for web applications to control I/O. Support UDP initial command set to setup LT200. Firmware update via FTP protocol. DSock Update utility compatible. Web server inside. Full source code for user to modify.

Because source code released (LT200 firmware source code, Windows TCP control program source code, Windows UDP setup program source code and Windows Console SerTest program source code ), you can get a lot of benefits:

• Learn how to use our DSock in real application.
• Learn how to use our SerPort library.
• Learn how to develop web based application.
• Learn how to implement UDP setup protocol.
• Learn how to implement TCP control protocol.
• Learn how to use our "BIOS + X-DOS + User application" in one Flash.

• Installation
Show you how to setup LT200. You can use our UdpSetup.exe to...
• LT200 Usage
There are three ways to use LT200...
• Development
We use some DM&P libraries and divide our program function into those parts:
• TCP/IP & Server Functions
We start the development with DSock start-up project which already contains web server, FTP server and TELNET server. We remove the TELNET server that we do not need this function.
• UDP Setup Protocol
When use install LT200, the network configuration should be setup. At this time, the TCP function may not work. Use UDP broadcast function is best choice for this. Just plug network cable and user can use UDP setup program to initialize LT200.
• TCP Control Protocol
Because of TCP property, user can use TCP to control LT200 every where in the world. We define simple control protocol and write a Windows TcpCtrl program. We will show your more detail later.
• HTTP Control Protocol
For some application, we do not know what platform(Windows, Linux...) user use. A web based control page is useful for this. User can use any browser on any O/S platform to control message. You can find some useful technical coding on our source code.
• COM-to-Ethernet Function
Convert data between COM port and Ethernet like RSIP do is useful for some special application. It works as host-based mode of RSIP. To do this is very easy with our DSock and SerPort library.
• Save/Restore Parameters
We save all parameters in DSOCK.CFG. You will see how we save and reload data from file with UDP setup prptocol.
• Install Firmware & Maintain
When you finish development, we will show you how to install your program and update firmware in the future.
