Note 1:
This product is factory defaulted to the DHCP mode. It is intended that your network’s DHCP Server
provide the IP address assignment. If there is not a DHCP server on your network, the device will
default to IP address
169.254.102.39
.
Note 2:
A dynamic address assigned by the DHCP server may change if the server loses the Ethernet
connection or power is removed. If a device on the network that normally communicates with the
serial server is configured to communicate with a specific IP address of the serial server, and the IP
address has been changed, the device will not be able to communicate with the serial server.
The
Firmware Version
number (Vx.x.x) indicates the serial server's currently
loaded firmware release. From time to time new firmware is made available
and can be uploaded into the serial server using Vlinx Manager.
Flow Control
determines the type of handshaking that is used to control
sending and receiving of messages. Options include No Flow Control,
Hardware Flow Control (RTS/CTS) and Software Flow Control (XON/XOFF).
The Flow Control setting must match the requirements of the serial device
connected.
Note:
Select No Flow Control when setting the port as RS-422 or RS-485 4-wire.
Forced Transmit
controls the maximum amount of time that characters can
be buffered before sending the characters to the network. Larger values
decrease the number of network packets, but increase the amount of time to
receive characters. Smaller values increase the number of network packets,
but decrease the amount of time to receive characters. The range is 1 through
65535.
The
Hardware Version
number of the serial server hardware is displayed on
the Login page of Vlinx Manager.
Inter-character Timeout
controls the maximum duration between received
characters before sending the characters to the network. Larger values may
decrease the number of network packets, but increase the amount of time to
receive characters. Smaller values may increase the number of network
packets, but decrease the amount of time to receive characters. The range is 1
through 65535.
IP Address.
Software or hardware attempting to access the serial server via
the network must know the IP Address of the server. In DHCP mode (factory
default), the serial server requests and receives a dynamic IP address from a
DHCP server when it first connects to the network. If there is not a DHCP
Server on your network, this device will automatically default to IP Address
169.254.102.39
. If the serial server is unable to connect to your network
using this address, there are two methods to manually configure the IP
Address.
