Serial - Ethernet fieldbus gateway COMSOFT
RS232 / RS485

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.
