When DHCP is enabled on the serial server, on power up it sends a DHCP request to
the DHCP server, which assigns a dynamic IP address, subnet mask, and default
gateway to the serial server.
When DHCP is disabled (static IP addressing), the IP Address, Subnet Mask and
Default Gateway fields must be set manually by entering the appropriate addresses
in these fields. If you do not know what addresses to use in these fields, ask your
network administrator.
Notes:
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 .
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 IPaddress of the serial server,
and the IP address has been changed, the device will not be able to communicate with the
serial server.
FIRMWARE VERSION
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
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
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.
