“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: 169.254.102.100.

Note: Serial settings are grayed out when VCom
Mode is selected.
1. Change the description of the serial port if
needed.
2. Set the mode to RS-232, RS-422 (4-wire),
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. Set Data Bits. Options are from 5 to 8 Data Bits. 8
is most common and is the default.
5. Set Stop Bits. Stop Bits controls the number of
bits for end of character.
6. Parity controls the error checking mode, with
options of: No Parity, Odd, Even, Mark and Space.
7. “Flow Control” options are Hardware or Software or
None. Hardware is used for RS-232 only.

1. Port Settings: Four configurations are available:
TCP, UDP, VCOM Mode and Paired Mode.
TCP is the most common choice, and will be briefly
described below.
(Paired Mode uses the same settings as TCP.) Detailed
information about UDP and VCOM Mode may be found
in the user’s manual.
2. TCP Port Settings:
- Choose “TCP”.
- Choose either “server” or “client.”
- Enter the port number on which you want to “wait for
connections.”
- Enter the maximum number of desired connections.
- Specify who is permitted to connect.
Depending on the Mode selected, there may be
advanced functions available. Option is grayed out for
VCom Mode.
1. Connect RJ45 first. DHCP is enabled by default.
2. Power the device.
3. Connect the Serial Device.
RS-232 with DB9: straight-through for DCE device.
Null modem for DTE device.
RS-422/485 with terminal blocks.
1. Use included CD to install Vlinx Serial Server
Manager. If Autorun does not start, go to “My
