Bridge device

Purpose: connect 2 generic data streams.

Data stream source can be TCP connection, serial port, named pipe etc.

Bridge implements inbound/outbound transformers which could be useful if you need to replace some content or wait for specific data before sending it to target data source (see Transformers).

Bridge does not support forwarding modem registers (RTS/DTR etc).

This device does not create virtual serial port. It uses existing one.
that can be either physical or virtual (for example, Connector).

Due to generic nature of the bridge device, serial port register forwarding is not supported in Bridge device.
If possible, it is highly recommended to use another VSPE device which supports modem registers forwarding.
For example, TcpServer, TcpClient, Serial Redirector etc. Those devices work more efficiently.

Below is example how bridge can be used with 2 connector devices:

Data flows

The arrows in Bridge properties page show how data is being processed for Bridge data sources.

Transformers

You can define transformers to customize inbound/outbound data flows (see Transformers).

Data sources

Bridge device supports different data sources.

TCP server data source

Listening to TCP port on local machine.

Bridge TcpServer data source

TCP client data source

Connecting to TCP address on local or remote machine.

Bridge TcpClient data source

File data source

Please note that Eterlogic service by default is running under LOCAL SERVICE account.
This account has minimum privileges on the local computer and presents anonymous credentials on the network.
It means that VSPE service will not be able to access files in your documents folder etc.
Make sure that file you are trying to read from/write has LOCAL SERVICE access permissions.

COM port data source

Named pipe server data source

Creates named pipe on local computer.

Bridge named pipe server data source

Named pipe client data source

Connectes to named pipe on local computer.
