Metrohm remote control language (see section 5.2) any printer with

serial interface (or parallel interface and parallel/serial converter) or a

personal computer (PC) may be connected. Any other measuring

instrument may be controlled via RS232 interface, as long as it supports

serial data transmission.

Fig. 23: Connection possibilities for the RS232 interface

In order to guarantee safe data transmission, it is important to set the

same RS232 interface parameters correctly for both instruments

connected (see section 2.5.2).

Control commands (examples)

CTL:RS &M;$G

starts a Metrohm instrument

CTL:RS &M;$S

stops a Metrohm instrument

PRINT: config

prints a configuration report to

a printer or PC

Scanning input data (example):

SCN:RS : *R"

waiting for readiness of a Metrohm

instrument
