VOLKTEK IRF-633 RS-232/422/485 TO 100BASE-TX DEVICE SERVER

RS-232/422/485 Transfer Configuration (Explanation follows below)
EXPLANATION: Server/Client Mode Configuration
Server/Client
Type
A read-only attribute. In Device Server mode, the device will have
a Server role as a TCP Server. In Media Converter mode, the
“Server” and “Client” roles of the two ends will be decided
automatically.
Remote IP In Media Converter mode, set the IP address of the other end
device. Ignore if in Device Server mode.
TCP Port Number The TCP port number that the TCP Server is “bound” to.
Connection Idle
Time
In seconds. This is valid for Media Converter mode only. The
Client will disconnect the TCP session if no packets are
transmitted in the set period.
DS/CR Mode DS: Device Server mode – the Device Server acts as TCP Server
and the Serial IP Redirector software acts as TCP Client.
CR: Media Converter mode – two Device Servers communicate
with each other through point-to-point architecture.
Packet mode of
serial input
This is valid for Device Server mode only.
Enabled – input data from the serial interface is treated as serial
packets.
Disabled – input data from the serial interface is treated as bit
streams.
Packet mode
inter-packet
timeout
In milliseconds. This is valid for Device Server mode only. It is
the delimiter value for recognizing the timeout gap between serial
packets if Packet Mode is enabled.
Serial Port Configuration
Operation Mode A read-only attribute. It shows the RS232/422/485 mode set by the
DIP switch.
Baud Rate The speed of the serial interface.
Parity Select or disable the parity checking method
Word Length The length of data in bits
Stop Bits The bit length of stop bits
Flow Control The flow control method for informing the correspondent
For 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 value to enable smooth
data communication.
To set the timeout value via console mode, first “Enable” the packet mode and “Save”
the settings. Once settings are applied, you will be able to change the timeout value.
In case you are using the product as a Managed Media Converter, keep “Packet Mode”
Disabled. In Managed Media Converter mode, the device must be paired with another
device.
Changes to the settings are saved to a system flash memory and do
NOT take effect until a system reset or reboot has occurred. This
action validates the new settings. Please note that you can’t change
the Device Server / Media Converter mode by using Telnet. Always
use Web Interface or Console access to change the Mode.
