    Setup and Connections ESERV-1xT Serial Servers SERIAL SERVER SETUP AND CONNECTIONS This section describes how to setup and connect ESERV-1xT 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.

  • Page 14: Connecting The Eserv-11T

    If you select RS-232 mode when you configure the serial server, you must connect the serial device to the serial server via a serial cable. The ESERV-11T is a DTE. If the serial device is a DTE, use a null modem (cross-over) cable.

  • Page 23: Description Of Serial Server Properties

    Server Properties ESERV-1xT Serial Servers 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.

  • Page 24: Delimiter 1, Delimiter 2 And Delimiter Removal

    Server Properties ESERV-1xT Serial Servers DELIMITER 1, DELIMIT ER 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. The serial server takes action when it recognizes the specified character(s) on its serial port.

  • Page 25: Dhcp

    Server Properties ESERV-1xT Serial Servers DHCP DHCP (Dynamic Host Configuration Protocol) is a protocol used on special servers that supply IP addresses to network nodes on request. 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.

  • Page 26: Ip Address

    Server Properties ESERV-1xT Serial Servers receive characters. Smaller values may increase the number of network packets, but decrease the amount of time to receive characters. The range is 1 through 65535. IP ADDRESS Software or hardware attempting to access the serial server via the network must know the IP Address of the server. In DHCP mode (factory default), the serial server requests and receives a dynamic IP address from a DHCP server when it first connects to the network.
  • Page 27 Server Properties ESERV-1xT Serial Servers Open Hyper Terminal or similar serial emulation software and connect to the COM port used in the step above. Ensure the port is configured to 115,200 baud, 8 data bits, and 1 stop bit. Enter Console Mode. Press and hold the serial server’s RESET SWITCH for 2 to 10 seconds.

  • Page 28: Link Status

    Server Properties ESERV-1xT Serial Servers LINK STATUS Link Status of the currently selected serial server is shown on the Login page of the Ethernet Serial Server Manager. Link status indicates the type of Ethernet connection between the computer and serial server. It will either display 10BaseT or 100BaseTX in full duplex or half duplex.

    It must not consist of all numeric values. SERVER SERIAL PORT NUMBER The Server Serial Port Number of the currently selected port is shown in this field. ESERV-11T serial servers feature one serial port. ESERV-12T serial servers feature two serial ports. Serial Watchdog Serial Watchdog controls the duration of serial inactivity when the serial port is determined idle and causes all connections for that serial port to be forced closed.
