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: 169.254.102.100.
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.
1. 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 100 ms.
2. 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.

3. Connect the Serial Device.
1. Use included CD to install Vlinx Modbus Gateway
Manager. If Autorun does not start, go to “My
Computer” and select the CD drive.
-- To start the installation on a 32-bit version of Windows double-click
on: CDROM:\Windows\32-Bit\MESR32.exe.
-- To start the installation on a 64-bit version of Windows double-
click on: CDROM:\Windows\64-Bit\MESR64.exe.
2. To open Vlinx Modbus Gateway Manager: click Start/Programs/
B&B Electronics/Vlinx/Vlinx Modbus Gateway Manager/Modbus
Gateway Manager.
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. If the device does not connect, cycle (unplug-replug) the
power, then try again.
(Alternative Method: Open a web browser and type the IP address
of the Modbus Gateway in the Address Bar. When the Modbus
Gateway is found the Login window will appear.)
5. Click “Login”. Password is blank from factory.
No password is necessary.

“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.
5 Set Up Serial Port
Note: The Vlinx Modbus Gateway Manager
software contains default parameter values
that are common to most Modbus networks.
1. Change the Description of the serial port if
needed.
2. Set the Mode to RS-232, RS-422,
RS-485 (2 wire) or RS-485 (4 wire).
3. Set the Baud Rate to control the speed of the port. Valid
rates range between 75 and 230.4k bits per second.
4. Stop Bits controls the number of bits for end of
character.
5. Parity controls the error checking mode, with
options of No Parity, Odd, Even, Mark and Space.
6 Finish and Log Out
