Signamax 065-1063FSx series RS-232/422/485 to 100Base/FX Device Server / Media Converter
29
While using this unit in the Device Server mode, in case you are using a serial device
with a 2-wire RS-485 application or Modbus RTU protocol, do not forget to “Enable” the
“Packet” mode of serial input. Also enter the appropriate inter-packet timeout or
delimiter byte values to enable smooth data communication.
Note:
You will not be able to change the serial port settings (Baud Rate, Parity, Stop
bits etc) while working in Device Server mode; they are managed through IP Serial
Redirector software.
Applications for Operation Modes:
Device Server Mode:
In this mode the Device Server acts in the Server role of the
RFC-2217 COM Port Control Protocol.
Converter Mode:
In this mode the Device Server acts like an advanced media
converter.
Like a normal converter, the Device Server communicates with a remote
Device Server in a peer-to-peer way. Also, the Device Servers communicate with each
other through an IP network in the TCP communication model. The TCP Client and
Server roles of the two Device Server peers are negotiated automatically.
