RS232 & RS485 Serial Applications
For RS-232
–
connect to the S2A-383S-20D1 PCB. Make sure the dip switch SW4 is set to RS-232. For
RS-485 communication, connect directly to the RS-485 port in the unit
–
positions A (D-) and B (D+).
Disconnect the serial converter wired to this port. Move the Red and Black wires labeled D+ and D- from
A and B positions to positions C and D. The converter is used to communicate to the S2A-383S-20D1

TCP/IP Applications
To configure the card for TCP/IP applications you need to configure the boards dipswitches on the S2A-
383S-20D1 PCB.
You will also likely want to change the IP, Subnet and Gateway. To accomplish this please refer to the
next section.
Changing the TCPIP Settings
The RTU to TCP/IP module is set at the factory as follows:
IP Address: 192.168.0.6
Netmask: 255.255.255.0
Gateway: 192.168.0.1
TCP Port Number: 502
To change the TCPIP settings it is necessary to load and install the DeviceInstaller Software provided by
Lantronix Inc. from the following URL:
http://www.lantronix.com/device-networking/utilities-tools/device-installer.html
Once this software is installed you should reconfigure your Network Adaptor to the same subnet (see
default settings above) as the Lantronix device. Connect the device to your laptop/PC using a null-modem
for a direct connection. Use a straight through if connecting through a switch or hub. If the device is
powered when you run the DeviceInstaller it will automatically begin a search and find the device. If
DeviceInstaller is running when the device is connected the Search command on the Toolbar Menu will
locate the device. Once the device is located, the screen should appear as pictured below.
