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 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.
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
When in VCOM mode this parameter is grayed out, because its value is controlled by the VCOM
driver on the computer.
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
65535ms.
Hardware Version
The Hardware Version number of the serial server hardware is displayed on the Login page of
Vlinx Manager.
Inter-character Timeout
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 65535ms.
