Message Text Content
Up to 300 data characters in each command string may be sent. The Command characters
(information between and including the “>” and “<” signs) are included in this maximum.
Printable and Non- Printing ASCII codes can be used in the message string. Refer to the ASCII
Code appendix of this manual for more information on ASCII codes and the Hexadecimal
value.
Non-printing characters are supported by use of a two-character command and can send a
Binary Code in the Range from 0-255. Double byte character to support combinations will
affect the maximum length count with each pair reducing the maximum data characters by 1.
Refer to the Non-printing Character information later in this section for information on these
values.
50B
Non – Printing Characters
Non Printing Characters are supported through use of a pair of two printing codes to equal the
non-printing code. This pair of characters is retained in the program code but sent as single 8-
bit code when transmitted.
There are three types of character pairs and each performs a different operation based on the
first character of the pair. This produces a single modified character for transmission.

Character Options
1.
The “&” two-character pair clears the 0x40 bit from the 2
nd
character code value.
2. The “!” two-character pair clears the 0x40 bit and sets the 0x80 bit set in the 2
nd
character
code.
3. The “$” two-character pair clears the 0xC0 bit in the 2
nd
character.
To transmit the single character with a value 0x01, use the two character sequence ”&A”. This
converts the “A” value of 0x41 to 0x01 by clearing the 0x40 bit. To transmit 0x81, use “!A” or
to transmit)xC1 use “$A”.

Exceptions / Additions
As the “&”, “!” and “$” are used as key indicators for the Non-print characters, there is a
special format used when these characters are used as a print character in the message text.
Simply use the character twice. “&&” = “&”
The ESSI style part program uses several unique characters which requires special two
character codes to be used. For example, the message code “&K” in the part program will
transmit the code value of 0x2B which is the ASCII code for the plus sign (+). In order to send
the + character the code “&K” must be used.
