This document describes the RS232 interface of the Modul1000 and the "ASCII" and
"Binary" communication protocol.
In case the leak detector shall be controlled via RS232 (for example START, STOP,
ZERO, etc.), select control location "RS232" or "local and RS232" at the leak detector
(see Technical Handbook).
Both interface protocols use these communication parameters:
19200 baud, 8 data bits, 1 stop bit, no parity
You can select between two RS232 protocols:
• The ASCII protocol is a human readable protocol, which can be used with a
simple terminal program. It is similar to SCPI (Standard Commands for
Programmable Instruments), a standard protocol widely used for measuring
equipment.
• The binary protocol is optimized for secure and fast communication between the
leak detector and a PC or PLC.
