■ INTRODUCTION
The DVS-232-2 is a compact, rugged, industrial-grade RS-232 device server that supports one
channel bi-directional RS-232 to Ethernet conversion which can be used to transmit serial data
over Ethernet and TCP/IP network. The applications of the DVS-232-2 include acting as an RS-232
to Ethernet converter or a Modbus RTU to Modbus TCP protocol converter; controlling RS-232
serial devices from remote Modbus TCP software or Modbus RTU master via Ethernet network;
making a wide variety of M2M communication applications possible by enabling client access
independent of any operating system or proprietary protocol; extending RS-232 serial
communication distance over Ethernet network; and converting conventional serial data network
into TCP/IP network. The DVS-232-2 was designed for harsh industrial environments and
withstands a wide temperature range of -40ºF to 185ºF (-40ºC to 85ºC) and is equipped with
15kV ESD and 600W surge protection. The unit supports TCP and UDP for both server and client
modes, and it features static IP and DHCP for minimizing configuration errors caused by manual
entries. The DVS-232-2 features auto-negotiation for 10 or 100M data rates, and it also supports
MDI and MDI-X (auto-crossover); no DIP switch or jumper settings are required.

■ TROUBLESHOOTING
Make sure the power supply (5 to 36 VDC) is connected and turned on.
Check LEDs and make sure connections are correct.
Be sure that the DVS-232-2 and your PC are at the same sub network and the COM port settings
match with each other (see “Factory Settings” table).
Press the “reset” button for 5 to 15 seconds to restore factory settings, if necessary.
Test with CommFront’s Serial-TCP/IP software (the free version can be downloaded from:
https://www.commfront.com/pages/downloads):
1) Set Serial-TCP as a TCP client and connect to device server’s TCP port (act as a TCP server).
2) Send Hex commands to DVS-232-2’s TCP port from the Serial-TCP’s “Packet Sender” tool.
When the command reaches the device server’s TCP port, it will be forwarded to device server’s
COM port and come back to Serial-TCP software’s COM port, thus creating an infinite loop. Click
the “De-activate” button to stop the loop.
