RS-232 Sengs
All RS-232 sengs are binary values, they can be ON or OFF.
If ECHO is on, all received characters are echoed back. This can be handy when programs like hyperterminal are
used.
LF is Line Feed. Line feed is an ASCII character (0x0A) which is somemes used to let the cursor jump to the next
line. Concept 1 always omits the line feed character. However, when LF is on, there will be put <LF> character
behind each <CR> character. This is both the case for echoing as for messages send by Concept 1. Please take a
look to following example: in both cases, the user sends the following string: “get msclvl<CR>”.
With ECHO on and LF o, this will be returned by Concept1:
“get msclvl<CR>”
“MSCLVL -16<CR>”
In case both ECHO and LF are on, it will be like this:
“get msclvl<CR><LF>”
“MSCLVL -16<CR><LF>”
BS is Back Space. This is also an ASCII character. In case BS and ECHO is on, Concept 1 will reply <BS><SP><BS> each
me when a <BS> is received. <SP> is the space character. This seng is only intended to have a “nice” text when
used with programs like Hyperterminal.
With HEADER on, each string, both incoming as outgoing, has to start with “>” (ASCII character 0x3E) as header
of the string. This funcon works only when ECHO is OFF! Please note that for the rst replies aer start up, this
funcon will not work correctly. The reason for this is that the sengs are loaded later. Anyway, this shouldn’t be
a problem. If ECHO and LF are put o and HEADER is put on, each string will start with “>” (ASCII character 0x3E)
and each string will end with <CR> (ASCII character 0x0D). This can help in making the string handling easier. Please
don’t forget that also instrucons will have to begin with “> “ in this case! Example (with MULTIZONE and VALFB
ON):
Instrucon: >SET MICLVL ZONE1 -35<CR>
Reply: >MICLVL ZONE1 -35<CR>
