Server Properties Configuration

Force Transmit

This field allows the user to set a maximum time limit between transmissions of data. The value set in this field multiplied by 100 ms determines the Force Transmit time. When the elapsed time reaches the time configured in this field, the TCP/IP protocol will pack the data currently in the serial buffer into a packet and send it out the Ethernet port.

Port Status

This field indicates whether a serial port is connected via the Serial Server to a virtual COM port of a device on the network.

TCP/UDP Port

This sets the port number for connection. The default port number for the ESR901 serial port is 4000. The default port numbers for serials ports 1, 2, 3 and 4 are 4000, 4001, 4002 and 4003 respectively.

In all modes of operation, Direct IP or Virtual COM, the port number set in the Server Properties menu must match the Virtual COM or socket software port settings.

Note:

Example: The Virtual COM default setting is TCP/UDP Port 4000. If the port # property is changed to 4001, the virtual COM port will have to be changed to 4001. The hardware settings can be changed from the ESP Manager or Console Configuration Menu. The Virtual COM port setting also can be changed within the Device Manager of the computer on which it is installed.

Serial Port Mode

Serial Port Mode allows configuration of the serial server for the following modes of operation:

•Console – When this mode is selected and the server is updated, a PC running a communications program such as HyperTerminal can communicate with the Serial Server via the Console Mode serial port (the serial Port on ESR901 or Port 1 on ESR902/904), displaying the Server Properties screen and allowing configuration of the server and its ports.

•Upgrade – When this mode is selected and the server is updated, firmware can be uploaded into the Serial Server via the Console Mode serial port or a virtual COM port mapped to the number of the Console Mode serial port.
