The unit can be controlled from an external PC (using the
dedicated software) via the RS232 C serial interface fitted to
the unit. Data communication from laboratory instrument to
computer is only possible on demand of the computer.
• The functions of the interface lines between laboratory
instrument and automation system are selected from
the specified signals of the EIA-standard RS232 C,
corresponding with DIN66020 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 RS232 C,
corresponding with DIN66259 Part 1 applies.
• Transmission method: Asynchronous signal transmission
in start-stop-operation.
• Mode of transmission: Fully Duplex.
• 1 start bit; 7 character bits; 1 parity bit [straight (even]);
1 stop bit.
• Transmission speed: 9600 bit/s
NOTE:
Forbid to plug in or plug out the RS 232C
communication line!
