Question about Digi One SP's data reliability and supported OS

Hi All,

I have some questions regarding Digi One SP:

  1. Does Digi One SP support Linux (Red hat ES 5) or Unix (AIX)?

  2. Does Digi One SP support reliable communication (no data lost)?

  3. Our Equipment previously communicated with PC dirrectly via COM ports, now if we use Digi One SP to bridge between PC and Equipment, do we have to change Equipment to comform to any special communication protocol of Digi One SP?

Many thanks for your answer.

Regards,
Tuan

  1. Does Digi One SP support Linux (Red hat ES 5) or Unix (AIX)?

A: The Digi One SP is a device server, i.e. hardware, and does not have an onboard OS like RH or AIX. We do however have a comm-port redirection software called Realport which is available for either of these operating systems.

  1. Does Digi One SP support reliable communication (no data lost)?

A: If flow control is enabled this would be true.

  1. Our Equipment previously communicated with PC dirrectly via COM ports, now if we use Digi One SP to bridge between PC and Equipment, do we have to change Equipment to comform to any special communication protocol of Digi One SP?

You likely wouldn’t need to change any protocol, just install the Realport driver on the server where your application runs, and the serial devices (/dev/ttyxxx in Unix/Linux, comm ports in Windows) will be created for your application to use.

Please select your OS from the drop-down at this link for OS compatability:

Thanks for your answers.

About #1: How many COM ports does Realport support on Linux and Unix?

About #2 & #3: Sorry if my question is repeated, but if flow control is enabled, do we have to modify our legacy applications?

The maximum supported devices/ports is outlined here:

Flow control is implemented on the serial port and the attached serial device. If your legacy application works on a standard serial port, it should also work with RealPort.
