The user may change this. Default is 255.255.255.0 Gateway The Gateway IP address allows users to access the Serial Server from outside the LAN. MAC Address The MAC address is fixed and cannot be changed. It is assigned in the factory. Every Ethernet device manufactured has it own unique MAC address. Version & Date The currently loaded version of the firmware, and when it was released, is shown here. Link Status Link status automatically displays the type of Ethernet connection. It will either display 10BaseT or 100BaseTX in full duplex or half duplex. This will depend on the LAN, switches, hubs used in the LAN topology. Server Serial Port This field indicates the number of the port for with Serial Server properties are currently being displayed. Changing the number in this field will cause all the other fields to display the properties for the specified port. Note, however, that before changing ports, any changes to properties must be Updated (Saved) or the Serial Server will not retain them. Baud Rate The serial port baud rate on the Serial Server must match the serial baud rate of the connected device unless using Virtual COM Mode. In Virtual COM Mode the software program will establish serial settings. Data/Parity/ Stop Set this to match the data format used by the serial device connected when Virtual COM Mode is not being used. 34 Chapter 5 Manual Documentation Number: ESP901- 902- 3704 B&B Electronics Mfg Co Inc – 707 Dayton Rd - PO Box 1040 - Ottawa IL 61350 - Ph 815- 433- 5100 - Fax 815- 433- 5104 – B&B Electronics Ltd – Westlink Commercial Pk – Oranmore, Galway, Ireland – Ph +353 91- 792444 – Fax +353 91- 792445 – Server Properties Configuration Flow Control The Flow Control setting must match the requirements of the serial device connected. N NNo oot tte ee: :: Select None when setting the port as RS-485 or 4-wire RS-422. TCP/UDP Protocol Select TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) protocol. If the application does not require a UDP connection, select TCP. TCP guarantees reliable communication with error checking whereas UDP provides faster transmission. UDP Mode When UDP mode is chosen the Serial timeout, TCP alive timeout, Connection mode, Connection at, Max connection and Remote IP address fields are replaced with the following four fields: Destination IP address range, Port number and Source IP address range. In this mode the server can be configured to broadcast data to and receive data from multiple IP addresses. Four IP address range fields are provided. Figure 32. The Server UDP Configuration Screen Serial Timeout Default for the Timeout property is 0, or no timeout. Setting Timeout to any value between 1 and 65535 seconds activates it. If Timeout is set to 5 seconds and the Serial Server is configured as a Server, the Client makes a connection and communications starts. If Manual Documentation Number: ESP901- 902- 3704 Chapter 5 35 B&B Electronics Mfg Co Inc – 707 Dayton Rd - PO Box 1040 - Ottawa IL 61350 - Ph 815- 433- 5100 - Fax 815- 433- 5104 – B&B Electronics Ltd – Westlink Commercial Pk – Oranmore, Galway, Ireland – Ph +353 91- 792444 – Fax +353 91- 792445 – Server Properties Configuration communications are ideal for 5 seconds the Serial Server will reset and make itself available for another client connection. TCP Alive Timeout The Serial Server monitors TCP activity. If TCP activity stops for the length of time specified in this field the connection will be closed. This field can be set to any value between 0 and 255 minutes. If zero, or no value, is entered into this field the server will not disconnect. Connection Mode The Connection Mode field has three options: Server, Client and Client (no heartbeat). When Client or Client (no heartbeat) is selected the Connection at field automatically becomes active (allowing the user to select Power up or Data Arrival) . • When using the Virtual COM Port feature, select Server. • When using a TCP or UDP Socket program, select Server. • When using Paired Mode communication between two serial servers set up one as a Client and the other as a Server. • When connecting to a server that does not support Heartbeat, select Client (no Heartbeat). Delimiter HEX 1 and Delimiter HEX 2 These fields allow the user to enter two ASCII characters (in hex format) that delimit the beginning and end of a message. When a message with both these delimiters is received at the serial port, the data contained in the serial buffer is placed in an Ethernet packet and sent out the Ethernet port. If only Delimiter 1 is set (Delimiter 2 is zero or blank), upon receiving Delimiter 1 the ESP901/902 will put all the data in the serial buffer in an Ethernet packet and send it out the Ethernet port. If serial data greater than 1 kilobyte is received it will automatically be placed in an Ethernet packet and sent out the Ethernet port . Force Transmit This field allows the user...
