EM100 Embedded Ethernet Module |
|||
|
Features:
Provides a way to quickly network-enable any Serial-based Product
Can be used as a communications coprocessor, or as a main building block of a standalone communications device (similar to the DS100 Serial Device Server)
Very compact, dimensions 46mm(l) x 28mm(w) x 13mm(h) only
No external components needed- just add a RJ45 connector
10BaseT Ethernet interface on one "side"
Serial (TTL) interface on another side- connects directly to the serial pins of microcontrollers, microprocessors, etc.
Supports both RS232 and RS485 communications (through the use of external driver IC)
Supports a subset of a standard TCP/IP protocol stack
Ideally suited for equipment utilizing Command/Reply- style (packet-based) serial communications protocol
Flexible, has many adjustable functioning parameters and internal non-volatile memory to keep them
No changes to the original Serial Device's communications protocol or firmware required
Supplied with a Virtual Serial Port Driver (VSPD) for Windows- existing PC software can be used without any modification too
Fully compatible with the DS100 Serial Device Server
Internal firmware can be upgraded in the field
12 general-purpose digital I/O lines can be used to control loads, input sensor states, etc.
EM100SK Starter Kit available
FCC/CE approved
Description:
The EM100 Ethernet Module is a compact Ethernet-to-Serial converter that fits easily into any existing Serial Device and provides a fast and inexpensive way to connect it to the 10BaseT Ethernet LAN. One side of the EM100 attaches directly to the serial pins of the Host microcontroller (microprocessor, etc.), another side- to the Ethernet (RJ45) connector.
There are several ways in which you can communicate with the DS100-equipped Device:
COM port redirection. If you want to continue using existing PC/Windows software (that was meant to communicate with your Serial Device directly, via the RS232 or RS485), then our Virtual Serial Port Driver (VSPD) is the solution for you. VSPD creates a number of Virtual Serial Ports on your PC. Each port works exactly like a normal hardware port but in reality reroutes the data via the TCP/IP network. With the VSPD installed you can continue using your PC software as if your Serial Device was still attached to the PC’s Serial port.
Direct Socket Communications. If you are creating your own PC software, then you can communicate with the Device directly. Modern software design packages like Visual Basic from Microsoft make it extremely easy to send and receive UDP packets. Our Application Note Using VB to communicate with the DS100/EM100 provides a detailed information on this subject.
Virtual Serial Link. If you are using a non-PC device to communicate with your Device or your PC is not running Windows, then you can use an additional DS100 Serial Device Server to form a virtual serial link. This way you will still have a simple Serial interface on both sides of the link.
Applications:
The EM100 can be used to network-enable many existing Serial Devices, such as...
