SNL2-E
Ethernet/RS232/RS485 Gateway
SNL2-E – the optimal solution for connection
of serial interfaces and Ethernet networks of up to 100 Mbit/s. SNL2-E
allows the connection of two serial end devices. The serial interfaces
can be configured via software as RS232- or RS422/RS485 interfaces. Also,
a mixed operation mode is possible.
In addition, for operating the RS485 bus, terminating resistors can be
switched on via software. Operation in TTY mode can be realized by means
of an external adapter.
Both interfaces support full duplex DMA mode operation. In synchronous
operation mode, rates of up to 1 Mbit/s can be reached.
The protocol firmware is loadable. The serial interfaces can be run completely
independent from each other. On every serial interface a different protocol
driver can be loaded and run.
DF-compatible driver interface
For Windows, as well as UNIX operating systems the DF-board compatible
interface allows the replacement of an existing DF-board by an SNL2-E
module without any changes in the application software. Compared to solutions
based on conventional PC communication boards, SNL2-E offers completely
new aspects for the connection of PC-based systems:
- Hardware/driver installation with its typical problems is bypassed
- Access to the serial interface is possible from every PC in the network
- Trouble-free integration of lower automation levels into the control
and design level
