The Serial-to-Serial
solutions are used when protocol conversions and/or emulation between two or
more serial interfaces are required. Typical applications are:
-
RS232-to-RS485 conversion.
With or without multiplexing and de-multiplexing of data from multiple RS485
devices into one RS232 data stream.
-
Realizing a FTP or email
interface for data transfer with a serial OEM device using a direct SLIP or PPP
connection to a PC, Laptop or PDA with RS232 interface.
-
Realizing a PPP
dial-in/dial-out
modem interface for a device that only supports direct SLIP or PPP over a serial
line. (device that does not include modem support)
-
Web enabling a serial
device using a direct SLIP or PPP connection to a PC, Laptop or PDA with RS232
interface.
Solution example 1: OEM
specific RS232-to-RS485 converter
Solution
The NCS0401 is used for
realizing a standalone protocol converter that supports dedicated or OEM
specific conversion functions that simple commercially available RS-converters
do not supports. Examples of such functions are:
-
Multiplexing/de-multiplexing
of multiple RS485 connections over a single RS232 link.
-
Intelligent
bridging (time-out or BOOT/EOT character based or using dedicated OEM message
parser
-
Conversion from
protocol X on RS232 link to protocol Y on RS485 link.
-
Conversion from
synchronous to asynchronous protocols. Synchronous communication is supported
for RS232 ports of NCS0401.
-
Multi-port
conversion. (NCS0410 has total of 3 serial ports)
