Rf2217 Mode - Planet Networking & Communication ICS-2100T User Manual

4.5.2.3 RF2217 mode

RS232 to Ethernet Connector allows to choose the transmission protocol, supporting connections using either the RAW data
transmission algorithm or the Telnet (RFC 2217) protocol.Therefore, Telnet can act as an interface to a network device server
connected to a remote serial device. The RF2217 mode screenshot in

Description
TCP keep alive interval shows how many seconds the unit waits during an inactive
connection before checking its status. If the unit does not receive a response, it will drop
that connection. The default is 0 minute.
This parameter describes the TCP port that communicates with the connected device.
The setting slave and master destination IP parameters must use the same value to
achieve communication. The range of value is from 1 to 65535. The default is 5004 for
port 1, 5005 for port 2, 5006 for port 3 and , 5007 for port 4
This parameter can be used to control the data packet. When the device port is in the
buffer until the specified data is accumulated, the data will be packed and transmitted by
the network. This parameter is 0 to indicate that the data will not be packed until the
buffer is full. The range of value is from 0 to 1024. The default is 0.
If the Separator is enabled, the serial receive character port will be discarded until the
start separator is detected on the serial port. When the end separator is received, the
buffered characters, including the start and end separators, are sent to the network.
The range of value is from 0 to FF. The default is disable.
Separators are ASCII characters specified by the user when configuring the serial serve.
This parameter describes how to control characters received on a serial port are sent
across the network. The default is Do nothing.
Do nothing: it will pack the accumulated data including Separators.

Strip Separator: it controls striping of Separator from the received characters

before the received characters are sent to the network.
Separator timeout controls the maximum amount of time that can be used to buffer
characters before the characters are sent to the network. A smaller values will increase
the number of network packets, but reduce the amount of time to receive characters, on
the contrary, Larger values reduce the number of network packets, but increase the
amount of time to receive characters. The range of value is from 0 to 65535. The default
is 0 ms.
