Building Custom CRCs for Non-Standard Protocols

Posted by Kevin Rutherford on May 17, 2018 2:00:00 PM

If you’ve been following our blog series on custom error detection, you’ll remember that OmniServer provides a large number of pre-defined Error Detection Codes (EDC) for use in different protocols for non-standard device communication.  And, again, it’s not uncommon to find an EDC from a vendor that is not pre-defined due to some specialized handling by the device manufacturer.

As we covered in our previous posts on creating a custom checksum and LRC, OmniServer gives you the ability to build custom EDCs in an OmniServer protocol to handle these situations.  This post, the final of three on custom Error Detection Codes, covers the basics steps to creating a custom CRC (Cyclic Redundancy Check) in an OmniServer protocol.

Building Custom LRCs for Non-Standard Protocols

You may be aware that OmniServer provides a wide variety of pre-defined Error Detection Codes (EDC, also known as CRC, LRC and Checksums) for use in protocols for non-standard device communication.  However, it’s not uncommon to find an EDC that isn’t pre-defined due to some specialized handling by the device manufacturer.

To handle such situations, OmniServer provides the ability to build your own custom EDCs in an OmniServer protocol.  This post, the second of three on custom Error Detection Codes, will cover the basics of creating a custom LRC (Longitudinal Redundancy Check) in OmniServer.

Building Error Detection Codes for Custom Protocols

Posted by Kevin Rutherford on Mar 15, 2018 2:00:00 PM

If you’ve worked with OmniServer to connect your non-standard devices in the past, you may be aware of the large number of pre-defined Error Detection Codes (EDC, also known as CRC, LRC and Checksums) available.  However, as is the nature of custom protocols out there, it’s not uncommon to find an EDC that isn’t pre-defined due to some specialized handling by the device manufacturer.

To that end, OmniServer provides the flexibility to define your own custom EDCs in an OmniServer protocol.  This post, the first of three on custom Error Detection Codes, will cover the basics of creating a simple custom checksum in OmniServer.
