1 Introduction The Quatech DSE-410D Dual-Port Ethernet Serial device server provides Ethernet to Serial connections for RS-232, RS-422, or RS-485 devices. The serial ports can be accessed over a LAN/WAN using “Direct IP Mode”, “Virtual COM Port”, or “Paired Mode” connection. The 10/100 Mbps Ethernet connection auto-selects 10 BaseT or 100 BaseTX and indicates the type of connection with a bi-color link light.
Communication Modes The DSE-410D enables communication with serial devices over a LAN or WAN. Serial devices are no longer limited to a physical connection to the PC COM port. They can be installed anywhere on the LAN using TCP/IP or UDP/IP communications. This will allow traditional Windows PC software access to serial devices anywhere on the LAN/WAN network.
Heart Beat Connection The Heart Beat Connection provides an extra measure of reliable communications assurance in Virtual COM Port Mode or Paired (Tunneling) Mode. This feature restores the TCP connection if communication is temporarily lost at either end due to loss of power or Ethernet connection. Without this feature, a device that loses a connection and stops communicating would not be able to reconnect without human attention to correct the problem.
Step 2: Attach the DSE-410D to your network’s switch or hub using a standard Cat 5 Ethernet cable, or directly to the LAN port on your computer using a crossover cable. You can connect your serial devices now if needed. If using Telnet for setup, refer to the Console mode section, Chapter 9, and Chapter 5, then power up the DSE-410D. Step 3: If using Windows, install the Quatech DSE-410D Manager software on the configuring Computer. Step 4: Power on the DSE-410D and check the status lights.

Top View Power Connection Connect the included power supply to the DC-IN jack, and then plug the supply into the local power outlet. When power is applied, the Red power light will illuminate. The tip of the power plug is positive, the sleeve is negative. The standard 12VDC/500mA power supply for North America shipment is 120VAC/60Hz; for Europe, Pacific, or UK it will be 230VAC or 240VAC/50Hz. Reset Button This button “soft” resets the DSE-410D, similar to removing/re-applying power.
RS-485 Mode The RS-485 mode supports the Transmit and Receive Channels using 2-wire halfduplex operation. The data lines are differential with the Data B line positive relative to Data A in the Mark state. Ground provides a common mode reference. Refer to the Pin-out table for connections. Selecting Internal RS-485 Bias Resistors You can select RS-485 Receiver Biasing from the DSE-410D if your network doesn’t supply any.
Upgrade Mode You can install newly revised firmware for the DSE-410D using RS-232 connections from a PC, through either the DSE-410D Manager or through the Virtual COM port. See Chapter 8 for details. Console Mode The Console mode provides access to the configuration menu using RS-232 connections. Connect a null modem crossover cable between the Multi-Interface port and one of the computer’s RS-232 serial ports.
The DSE-410D has two DB-9 male connectors. DSE-410D Port 1 - Multi-Interface, dip-switch selectable RS-232, RS-422, or RS-485 DSE-410D Port 2 - RS-232 only RS-232 Connections In the RS-232 mode, the ports are configured as DTE (Data Terminal Equipment), like a computer. DTE Device (Computer or DSE-410D) When connecting to a PC or another DTE device, use a null modem crossover cable. When connecting to a DCE device that can normally be plugged into a PC, use a straight through cable.
RS-422 Connections In the RS-422 mode, TXD lines are outputs and RXD lines are inputs. Connect the TXDB(+) line to the RXDB(+) line of your device, and the TXDA(-) line to the RXDA(-) line of your device. If Flow Control is set for RTS/CTS, connect the RTSB(+) line to the CTSB(+) line of your device and RTSA(-) to CTSA(-) of your device. Connect from CTSB(+) to RTSB(+) of your device and from CTSA(-) to RTSB(+) of your device.
RS-485 Connections Some RS-485 devices are marked opposite from the RS-485 standard that defines the Data B line as positive relative to Data A during a Mark state before enabling the transmitter, and after transmitting before tri-stating. If the RS-485 devices don’t respond, try swapping the Data B and Data A lines. If you want to connect 4-Wire RS-485 devices, you can use the RS-422 Mode provided that the DSE-410D will be connected as a Master in a single master system.
