Serial Device Server- Dual Port Quick Installation Guide Introducing the Serial Device Server The Serial Device Server-Dual Port allows to connect a serial device to a Local Area Network (LAN) or Wide Area Network (WAN). Features and Benefits • Convert serial device (RS-232, RS-422, RS-485) data/ signal into the TCP/IP package data/signal and send them out with the Ethernet DataStream;...

Overview Serial Device Server-Dual Port is designed to make your serial devices Internet ready instantly. ARM-7 Series of Serial Device Server-Dual Port makes them the ideal choice for connecting your RS-232 or RS-422/485 serial devices— such as PLCs, meters, and sensors to an IP-based Ethernet LAN, making it possible for your software to access serial devices anywhere and anytime over a local LAN or the Internet.
Low-cost devices usually are equipped with low speed processors and limited memories. In reality, they are neither having the capability nor practicality to manage complicated network TCP/IP protocols. ARM-7 Series is a low cost while providing high performance network solution by converting data stream between network TCP/IP and popular serial port signals.

Power Supply The Serial Device Server-Dual Port is powered by a single 9V DC, 500mA (inner positive/outer negative) power adapter. Connect the power line to the power outlet at the left side of Serial Device Server-Dual Port and plug the adapter into a reliable power outlet.

Reset Button Press the Reset button then turn on the power. Wait for 3 seconds. The converter will reset to factory default. Terminator There is terminator resistor built in. If the switch 1 & 2 are set in ON position , 120 Ohm resistor is connected between the signals.
RS-422/RS-485 Wiring Architecture When you finish the steps mentioned above and the LED indicators are as shown, the converter is installed correctly. You can use the setup tool ETM.exe to set the IP Address. To proceed with the advanced parameters setup, please use a web browser (IE or Netscape) to continue the detailed settings.

Figure 3 Menu View Click View , then Refresh or F5 key to refresh the status. ETM will send another query to get updated information, see Figure 4. Click View, then Exit or Alt+4 to exit the program, see Figure 4. Note: Always run Refresh after data change.

Menu Config Click Config, then IP Address, see Figure 5. Press ENTER or select IP Address in the Config menu, a dialog will be shown see Figure 6. Note : Because ETM uses broadcast UDP packets, for the sake of security, it allows configuration only when device setup password is empty.
Assign an IP Address with the same Subnet Mask of your computer, avoiding any IP conflict with other network devices. When you press Ok, the IP address will be refreshed in 2-3 seconds, see Figure 7. Figure 7 Web Console Configuration In addition to basic IP address and subnet mask, specific device settings can be set through HTTP protocol with popular browsers, e.g.

Controller Status The Login Page Setup of Serial Device Server-Dual Port is as easy as surfing on WWW, no special software is required. Popular Browsers can easily do the setup process. In the browser URL field, set the IP address of device directly, To enter the Controller Status page, please follow the steps below.

Field Description • System time elapsed The time elapsed since start of this device in [Day Hour : Minute : Second] format. This information can be useful in identifying the reliability of system. • Firmware version Converter firmware is identified by date code. This information will be required in looking for technical support.
Controller Setup • The Setup Page Type the correct password in the Password field and click the Login button in the Controller Status page, then the Controller Setup page will appear, see Figure 9. Note: If you forget the password or can’t login successfully, please contact the manufacturer directly.

Field Description • IP Address Don’t let it conflict with the other devices on the network. If DHCP client mode is enabled and there’s a DHCP server on the network, this field will be assigned by DHCP server automatically. • Subnet mask Subnet mask of the Serial Device Server-Dual Port converter has connected to.
Page 15
• Network link speed Ethernet physical link speed. Auto means the speed is automatically selected by the converter, or specify 10Mbps or 100Mbps to match the speed of the HUB. • DHCP client DHCP client mode could be enabled/disabled. If DHCP is enabled, there should be a DHCP server on the network.

• TCP socket inactive timeout input This feature - inactive timeout - identifies whether the socket is active or dead. If there is no any data transferred (send/receive) within the defined timeout period (1 to 99 minutes), then it is probably a dead socket, and the socket will be closed automatically, thus a new connection can be accepted again.
Page 17
• Setup password Administration password used to login the Controller Setup page. It may be empty or up to 15 characters long. • Serial Port 1 The first serial port is RS-232. Socket port • Port number A socket port assigned for the serial port. It’s a 16- bit number, ranging from 1 to 65535.
• Baud rate, parity, data bits, stop bits Baud Rate: 300 ~ 230400 bps Parity: None, Even, Odd Data Bits: 5, 6, 7, 8 Stop Bit: 1 or 2 • Serial Port 2 The second serial port is RS-422/485. • Port number A socket port assigned for the serial port.

Controller Updated Press Update button after you finish the detailed parameter setting. The converter will save all parameters into internal non-volatile memory and then reboot, see Figure 10. It takes about 5 seconds to complete the whole process, and a new login page will be presented, see Figure 3.
Factory Default Setting If by chance, you forget the setup password, or have incorrect settings making the converter inoperable, there are two ways to reset the setting and the following procedures can be used to reset all settings to factory default: Turn off the power of the converter.

The wiring architecture is similar to RS-232 Wiring in page 5, and the serial device is replaced by the PC’s COM 1. The same PC also plays the roll of the Remote Host. Hyper Terminal for TCP/IP WinSock Initiate Hyper Terminal from the Start Menu in Windows, see Figure 12, give a terminal name, choose an icon, and press OK button, see Figure 13.

After OK button is pressed, see Figure 15 appears. Enter the converter’s IP address e.g. 192.168.0.10 at the Host address: field, and the Socket port number set for the Serial Port 1 at the Port number: field (e.g 4660). (The Socket type of the Serial Port 1 should be TCP Server.) After OK button is pressed, see Figure 14 appears.

Hyper Terminal for COM Port Initiate another Hyper Terminal as a COM Port Terminal, (see Figure 14, select COM 1 or other COM port instead of TCP/IP Winsock. Set the COM port Properties to be the same as those set for the Serial Port of the converter (9600.N.8.1).
