General information on RS232 interface

Many different instruments may be connected via the serial RS232 in-

terface 32

32. In addition to all Metrohm instruments that support the

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

rial interface (or parallel interface and parallel/serial converter) or a per-

sonal computer (PC) may be connected. Any other measuring instru-

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

serial data transmission.

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

same RS232 interface parameters correctly for both instruments con-

nected (see section 2.5.2).
