Data transmission via serial in-
terface
= starts Metrohm instrument in current mode
any character string with 14 characters
Data (=character strings) can be transmitted to connected devices via
the serial RS232 interface.
Make sure that the transmission parameters of the RS232 interface are
identical with those of the connected device (see configuration menu
>RS232 settings
Any letters, numbers and special characters can be selected from the
character set of the Advanced Sample Processor.
This function is primarily suitable for instruments that understand the
Metrohm Remote language. These can be controlled with so-called
triggers.
The most important of these are:
&M;$G
Go, starts instrument in current mode
&M;$S
Stop, stops device
&M;$H
Hold, interrupts determination
&M;$C
Continue, restarts determination
Switching on the AutoInfo status messages (e.g. in a start sequence)
can be carried out with the following Remote commands:
&Se.A.T.R"ON"
Status message at "Ready" condition
&Se.A.T.F"ON"
Status message at end of a determination
&Se.A.T.S"ON"
Status message at manual Stop
&Se.A.T.G"ON"
Status message at start of a method
&Se.A.T.E"ON"
Status message at error condition
Logically the corresponding AutoInfo messages should be switched
off again in a final sequence (
..."OFF"
).
Detailed information about the syntax of the Remote language can be
found in the Instructions for Use of your Metrohm instrument.
For communication with instruments from other manufacturers or a
computer please conform with their syntax and conventions.
