Slim-Link® W eb Server-Controller

June 2001

Micro-Controller incorporates Web-Enabled, Real-time Operating System

DESCRIPTION

The Slim-Link family of Web Server-Controller products provides the ideal core technology for Internet enabled instruments and control systems. The Slim-Link Web Server Controllers are based on a 40 MHz AMD186ES microcontroller and feature MicroRTOS, a web enabled, real-time operating system developed spedifically for control system applications. MicroRTOS is embedded into each Slim-Link Web Server-Controller product with no additional cost or licensing fees.

MicroRTOS

MicroRT OS was created to simplify the process of designing a web enabled instrument or control system. This is accomplished by integrating a Preemptive Real-time Kernel, thin Web Server, and TCP/IP Stack into the fully-functioning operating system. The designer can then concentrate on the design of his application rather than integrating source codes from disparate applications. Three editions of MicroRT OS are available to support your application; the Basic edition, PPP Client Edition with Point-to-Point protocol for dial out applciations and the PPP Server Editon with Point-to-Point protocol for in bound dial-up applications.

an impedance of 100 ohms.

2 TD- All TD- is the negative lead of the 10Base-T transmit pair. The transmit pair presents

an impedance of 100 ohms.

3 RD+ All RD+ is the positive lead of the 10Base-T receive pair. The receive pair presents

an impedance of 100 ohms.

4 RD- All RD- is the negative lead of the 10Base-T receive pair . The receive pair presents

an impedance of 100 ohms. 5 All No Pin 6 NSTAT All NSTAT is an active low output which indicates the status of the LAN connection

to the Slim-Link® Server. A low indicates the LAN connection is active. The

NSTAT output can sink up to 12 milliamps to drive an LED indicator. 7 NXMT All NXMT is an active low output. It goes low to indicate that the Slim-Link

Server is transmitting data onto the Local Area Network. The function of this

signal can be altered in the Ethernet Controller’s ISA Controller Status Register

7. The NXMT output can sink up to 12 milliamps to drive an LED indicator.

8 N/C All No Connection; reserved for future use. 9 N/C All No Connection; reserved for future use.

10 DIO0(TXDA) All This pin provides access to Programmable Input/Output 27 from the AMD186

controller. This I/O line can also be used as the Transmit Data input for Serial

Port A. Hardware Flow Control is not available on Serial Port A.

11 DIO1(RXDA) All This pin provides access to Programmable Input/Output 28 from the AMD186

controller. This I/O line can also be used as the Received Data output for Serial

Port A. Hardware Flow Control is not available on Serial Port A.

12 DIO2(/R TSB) All This pin provides access to Programmable Input/Output 20 from the AMD186

controller. This I/O line can also be used as the Request to Send output for

Serial Port B. Request to Send is used for hardware flow control. The Slim-

Link® Server deactivates Request to Send to stop the flow of data from the

peripheral equipment.

13 DIIO3(/CTSB) All This pin provides access to Programmable Input/Output 21 from the AMD186

controller. This I/O line can also be used as the Clear to Send input for Serial

Port B. Clear to Send is used for hardware flow control. When Clear to Send is

inactive, the Slim-Link® Server will not transmit data to the peripheral equipment.

controller. This I/O line can also be used as the Transmit Data input for Serial

Port B.

15 DIO5(RXDB) All This pin provides access to Programmable Input/Output number 23 from the

AMD186 controller. This I/O line can also be used as the Transmit Data input

for Serial Port B.
