Using the Redirector :: The Serial/IP Control Panel

Accept Connections

To change this setting

In the Serial/IP Control Panel:

1. Select a virtual COM port.

2. Select the Accept Connections check box.

3. In the associated Port Number, type a TCP port number that is available on the local computer.

4. The setting becomes effective without further action.

This setting will be used the next time this virtual COM port is opened.

A virtual COM port can be configured for outbound connections, inbound connections, or both.

Settings

Accept Connections set, Connect to Server blank

• The virtual COM port can only accept connections.

• User Credentials are disabled.

• The Configuration Wizard is unavailable.

• Extend Server Connection is disabled.

• While waiting for an inbound connection, data sent to the COM port by the application is discarded.

• If more than one Serial/IP COM port is configured to accept connections on the same TCP port number, arriving connections will go to the lowest numbered COM port that is available.

Accept Connections and Connect to Server both set

• The virtual COM port can both initiate and accept connections.

• User Credentials are enabled, but used only for outbound connections.

• The Configuration Wizard is available for testing outbound connections only.

• Deferred Port Open is disabled.

• While there is no active connection, data sent to the COM port by the application is discarded.

• CE_FRAME is not pulsed while the connection is down.

• If Restore Failed Connections is enabled, it functions for outbound connections only.  A failed inbound connection must be re-initiated by the other device/computer, and the Serial/IP Redirector will accept it.

• If Restore Failed Connections is disabled, the Serial/IP Redirector initiates a connection when the Serial/IP COM port is first opened. If that connection fails or is terminated by the server, the Serial/IP Redirector begins waiting for an inbound connection until the COM port is closed by the application.

Tips

Two copies of the Serial/IP Redirector can be configured for back-to-back operations. This provides a network equivalent of a serial crossover cable but with the speed and distance advantages of the network.

Some serial servers are able to run in "client mode" in which they initiate a TCP connection (to a preconfigured IP address and TCP port number) when a serial device becomes active. This allows a centralized application to passively collect data instead of actively polling.
