8. Command reference
796 Titroprocessor, Instructions for use 205 205
message. In this case it is advisable to pick up such a message with the
SCAN_RSx command (see below).
Command Parameters Parameters
ДДДДДДДДДДДДД ДДДДДДДДДДДДДДДДДДДДДДДД ДДДДДДДДДДДДДДДДДДДДДДДД
CTRL_RS1
For longer data or command sequences several CTRL commands can be
programmed one after another; these are always transmitted as data lines
with max. 50 characters.
Parameter
Character string / data
up to 50 characters
Any letters, numbers and special characters can be used.
Make sure that these can also be interpreted by the re-
ceiving instrument.
SCAN_RS1, SCAN_RS2
Interpret incoming data
In a sequence the SCN_RSx command has the effect of stopping the
method run until the predefined character string (up to 50 characters) has
been received via the serial RS 232 interface. Incoming data are checked
character by character.
Command Parameters Parameters
ДДДДДДДДДДДДД ДДДДДДДДДДДДДДДДДДДДДДДД ДДДДДДДДДДДДДДДДДДДДДДДД
SCAN_RS1
Parameter
Character string
up to 50 characters
Any combination of letters, numbers and special charac-
ters can be selected.
'*' can be used as place holder for
any character sequence. (If '*' is to be interpreted as an
ASCII character then '**' must always be used.) A place
holder can be set within a character string. When the first
part of the character string has been correctly recognized
a search is made for the first appearance of the character
which follows the
'*'. The comparison of the second part
of the character string is carried out here.
If a SCAN_RS command is used in a series of samples it is recommended
that the RS 232 interface used is first re-initialized. This has the effect of
clearing the input buffer of the interface and is carried out by pressing
[Config.] [Interfaces] [Reset RS232 X] on the Titroprocessor main
page.
