If You Wish to Set Up TCP
1. Use included CD to install Vlinx Modbus Gateway
Manager. If Autorun does not start, go to “My
Computer” and select the CD drive. You will see
a Vlinx MESR icon. Double-click it to launch the
installation.
2. To open Vlinx Modbus Gateway Manager: click
Start\Programs\B&B Electronics\Vlinx\Vlinx Modbus
Gateway Manager.
If the device does not connect, cycle (unplug-replug)
the power, then try again.
3. To configure via the network, select “Network”.
4. If you know the IP address, select “The device is
at this address,” and type in the IP address. If not,
select “I don’t know the IP address of the device.” Click
Connect.
(Alternative Method: Open a web browser and type
the IP address of the Gateway in the Address Bar.
When the Gateway is found the Login window will
appear.)
2 Install/Setup
“I want DHCP” is preselected to set up the network
using dynamic IP addressing. The Gateway is set
up at the factory to receive an IP assignment from a
DHCP Server.
1. If a DHCP Server is not available on your network,
it will default to 169.254.102.39.
2. If a DHCP server is not available and the default
address does not work on your PC, change your PC
network settings to IP Address: 169.254.102.1, Subnet
Mask: 255.255.0.0, Default Gateway: 169.254.1.1.
If you are not able to use these settings in your
installation, refer to the User’s Manual for directions to
change the Gateway’s TCP/IP settings.
Note: The Vlinx Modbus Gateway Manager
software contains default parameter values that
are common to most Modbus networks.
TCP Settings:
“Connect to port” identifies TCP port used in TCP
client mode. Valid range is 1 to 65535. Default is
502.
Response timeout is the maximum response time.
Valid range is from 1 to 65535. Default is 100ms.
TCP Server Settings:
“Listen on port” identifies TCP port in TCP server
mode. Valid range is from 1 to 65535. Default is
502.
“Limit the number of connections” controls the number
of simultaneous TCP clients that can be connected.
Connection Filter Mode options like “allow everyone,”
“allow specific IP address” and “allow a range of IP
addresses” control which TCP clients can connect.
5. Click “Login”. Password is blank from factory.
