Enter binary data using hex numbers (e.g. 0D0A). Only characters that represent hex numbers are
allowed (0-9, A-F, a-f). It is okay to put spaces between data bytes for clarity. Except for spaces, if
you submit the form with anything entered except for these characters, the web editor will prevent it
from being saved to the eCNA. The “Error: Invalid character” message is displayed.
ASCII characters must be inside the curly braces “{ }”. All 95 of the printable ASCII characters,
numbered 32 through 126 (decimal) are supported. However there are some limitations to using the
curly braces inside the curly braces.
The maximum length of a command code is 40 characters.
Examples of valid command code formats:
User Text Data bytes actually sent Comment

Examples of invalid command code formats:
User Text Comment

outside of the curly braces. Only 0-9, A-F, a-f characters are allowed in hex (binary)
mode.
AB 12 {Hello} \r \n
Web editor prevents this message from being saved. The “\”, “r” and “n” characters are
not allowed outside of the curly braces. Only 0-9, A-F, a-f characters are allowed in hex
(binary) mode.
{Hello World}}
Web editor prevents this message from being saved. The first right curly brace “}”
following the first left curly brace “{“ terminates text mode. If you really wanted to send
the message “Hello Word}”, you would enter: {Hello World}7D
For unsupport devices, you must use the Raw device selection and the enter the entire command
including a checksum (if required) as described the manufacturer’s documentation.
For supported devices, select the appropriate device. For convenience, it is only necessary to enter
the command itself. Any start byte, Id, checksum, etc. are automatically inserted into the message
before it is sent to the device. See Appendix A for details about configuration and messages for
supported devices .
