Server Properties Configuration

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 ESP901 is 4000. The default port numbers for the ESP902 are 4000 and 4001 for serial ports 1 and 2 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 ESP901 or Port 1 on ESP902), 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.

•Default – When this mode is selected and the server is updated, it will revert the server to its default configuration.

•RS-232– When this mode is selected and the server updated, the selected serial port will become an RS-232 serial port on the server.

•RS-422– When this mode is selected and the server updated, the selected serial port will become an RS-422 serial port on the server.

Server Properties Configuration

•RS-485– When this mode is selected and the server updated, the selected serial port will become an RS-485 serial port on the server.

Connection At

When the Connection Mode field is set to Client or Client (no heartbeat), this field becomes active, allowing the ESP901/902 (acting as a client) to connect to the server either on Power up or on Data Arrival (first character arriving).

Max Connection

This field allows the user to configure the Serial Server to have up to eight TCP connections.

Remote IP Address

This is a security feature activated by entering the IP address of the desired client. The Serial Server will only communicate with the listed IP address and all other requests for connection will be filtered out. The Serial Server must be set up as a TCP or UDP Server to use this feature. The default setting is 255.255.255.255.

If Paired Mode is not being used, do not change this setting until the application has been tested and is communicating properly. Then activate the address filtering feature.

Note:

Refer to Chapter 1 Paired Mode

Update/Save

Server properties must be updated separately for each serial port. Updating varies slightly depending on which of the four configuration user interfaces are used.

Updating the Server Properties in ESP Manager

From the Server Properties screen, click the Update button to store the configuration settings for the currently selected port. The vcomui dialogue box will appear indicating you must restart the device before the new settings will take effect. Click Yes.
