Ready LED The Ready LED (green) blinks once per second if the system is operating correctly. If the LED is off, it indicates the system is not operating correctly. Serial Port LEDs VESR921-x serial servers feature one serial port. VESR922x, serial servers feature two serial ports.
Hardware ETHERNET CONNECTOR Serial server models using 10BaseT/100BaseTX network connections use an RJ45 receptacle. The serial server is connected to a standard Ethernet network drop using a straight-through RJ45 (male) Ethernet cable. VESR92x models feature a second RJ45 receptacle which acts an Ethernet pass-through connection. This connection functions similar to an Ethernet switch and allows the connection of other devices to the network. Figure 6.
Hardware VESRxx Serial Servers use three serial port connector configurations, depending on the model: VESR901-x serial servers feature one serial port and use a DB-9M connector for RS232 and a five-position removable terminal block for RS-422 and RS-485 connections. VESR902D-x serial servers feature two serial ports, both using DB-9M connectors for RS-232, RS-422 and RS-485 connections.

Setup and Connections SERIAL SERVER SETUP AND CONNECTIONS This section describes how to setup and connect VESRxx Serial Servers. Note: In this section devices to be connected to the serial server’s serial connection are simply referred to as the “serial device”. CONNECTING THE POWER SUPPLY Connect a DC power supply to the power terminals on the top of the serial server. Polarity of the wires is indicated on the label on the side of the serial server. Acceptable voltages are between 10 VDC and 48 VDC.
Setup and Connections data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference. When configured for 2-wire operation the connection supports one signal pair: Data A (-) and Data B (+) signal channels using half-duplex operation. The data lines are differential with the Data B line positive relative to Data A in the idle (mark) state. Ground provides a common mode reference.
Setup and Connections The VESR902T-x has two serial connections that support RS-232, RS-422 and RS-485 (2- and 4-wire). The unit has two connectors, both of which are 5-position terminal blocks. Make the appropriate connections to the terminal blocks to match the serial connection mode you select when configuring the serial server. Note: Refer to Appendix D for connector pinout information. Figure 13.

Serial Server Properties DESCRIPTION OF SERIAL SERVER PROPERTIES The following serial server properties are ordered alphabetically to assist you in finding the information you need. BAUD RATE Baud Rate is the communication speed of the link between the serial server and the device attached to its serial port. Both these devices must be configured to operate at the same baud rate. Baud rate values range from 75 to 230,400 Baud. (Refer to Appendix B for specific baud rates that are supported.
Serial Server Properties The Default Gateway address sets the default route to remote networks, enabling users to access the serial server from outside the local network. DELIMITER 1, DELIMITER 2 AND DELIMITER REMOVAL Delimiters and Delimiter Removal enable you to control how characters received on a serial port are sent across the network. Delimiters are ASCII characters specified by the user when configuring the serial server.
Serial Server Properties When DHCP is enabled on the serial server, on power up it sends a DHCP request to the DHCP server, which assigns a dynamic IP address, subnet mask, and default gateway to the serial server. When DHCP is disabled (static IP addressing), the IP Address, Subnet Mask and Default Gateway fields must be set manually by entering the appropriate addresses in these fields. If you do not know what addresses to use in these fields, ask your network administrator.
Serial Server Properties The Hardware Version number of the serial server hardware is displayed on the Login page of Vlinx Manager. INTER-CHARACTER TIMEOUT Inter-character Timeout controls the maximum duration between received characters before sending the characters to the network. Larger values may decrease the number of network packets, but increase the amount of time to receive characters. Smaller values may increase the number of network packets, but decrease the amount of time to receive characters.
Serial Server Properties c. Use the Vlinx™ Manager Software to search for, discover, and configure the unit. 2. Method Two: Change the serial server’s network setting to match your PC using Console Mode a. Connect a null modem serial cable (crossover cable) from Port 1 on the serial server to an available COM port on your PC. b. Open Hyper Terminal or similar serial emulation software and connect to the COM port used in the step above.
Serial Server Properties f. Open the Vlinx™ Manager Software and select “Serial Port” as the method to connect to the device. g. After logging in, click on . h. Un-check the box next to “I want DHCP to setup the Network.” i. Re-configure the serial server’s Network Settings to something within the range of your PC’s Network Setting. For example If your PC is configured to: IP Address = 192.168.0.1 Network Mask = 255.255.255.0 Default Gateway = 192.168.0.
Serial Server Properties The Model number of the currently selected serial server is displayed on the Login page of Vlinx Manager. NETWORK PROTOCOLS Network Protocols available for use on VESR9xx serial servers include TCP, UDP, VCOM and Paired Mode . NETWORK WATCHDOG Network Watchdog controls the duration of network inactivity when a network connection is determined idle and causes the connection to be forced closed. The range is 1 through 65535 milliseconds.
Serial Server Properties Four serial interface modes of operation are: RS-232 - Point-to-point serial communications connection used by PC COM ports and many other systems. Capable of baud rates up to 115.2 kbaud over short distances (typically 50 feet). Typically uses DB-9 connectors but terminals are also used on VESR9xx serial servers. RS-422 - Point-to-point communications using a transmit pair and a receive pair. RS422 can operate at higher speeds and longer distances than RS-232.
Serial Server Properties SUBNET MASK The Subnet Mask specifies the network mask the serial server uses when on a subnetted network. For a Class A network (IP addresses 0.0.0.0 through 127.255.255.255) the default subnet mask is 255.0.0.0. For a Class B network (IP addresses 128.0.0.0 through 191.255.255.255) the default subnet mask is 255.255.0.0 For a Class C network (IP addresses 192.0.0.0 through 233.255.255.255) the default subnet mask is 255.255.255.0 For a Class D network (IP addresses 224.0.0.
Serial Server Properties In UDP mode, if you want to control what network node receives data, you must specify the IP address and UDP port the data will be sent to. You can choose to send to: Nobody All nodes at a specific UDP port number. (This is called broadcast.) Specific IP addresses and UDP port numbers. (This is called unicast.) A range of IP addresses and UDP port numbers. (This is called unicast range.
