15.1 Serial RS 232 C interface
15.1.1

Configuration

The unit can be controlled from an external PC (using the dedica-
ted software labworldsoft) via the RS 232 C serial interface fitted
to the unit.
To increase safety when controlling the RET control / t from a
PC, enable the watchdog function for monitoring the conti-
nuous serial data flow (see section 15.1.4).
• The functions of the interface lines between laboratory instru-
ment and automation system are selected from the specified
signals of the EIA-standard RS 232 C, corresponding with DIN
66 020 Part 1. The allotment of the bushing can be taken from
illustration.
• For the electrical properties of the interface lines and for the
allotment of the signal status, standard RS 232 C, corresponding
with DIN 66 259 Part 1 applies.
• Transmission method: Asynchronous signal transmission in start
-stop-operation.
• Mode of transmission: Fully Duplex.
