TruePort I/O
284 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
API Over TruePort Only
If you have a custom application that talks to a serial port, you can use TruePort as a virtual serial
port to communicate with the IOLAN over the network to access I/O data using the Perle API. You
also have the option of enabling SSL as a security option to encrypt the data that is communicated
between the IOLAN and the host machine (SSL/TLS must be configured in the Server settings and
on the TruePort host). See
Accessing I/O Data Via TruePort on page 285 for more information on
the API.)
