Piston Burette is equipped with two serial RS-232-C interfaces for data com-
munication with other devices. You can use these two interfaces to connect several devices to one com-
puter (PC) interface.
The plug connectors of the two interfaces are located on the devices’ back panel,

socket “1” makes the connection to a connected computer, a printer with a serial interface, or to the up-
stream device within the “daisy chain”. RS-232-C socket “2” can be used to connect additional devices
(daisy chain concept).

5.2 Setting the data-transfer parameters
All devices communicating with each other require the same transfer parameters. The following transfer
parameters are set ex factory:
Baud rate:
4800 baud
Data bits:
7 Bit
Stop bits:
1
Parity:
No.
If you wish to change the data-transfer parameters, press the <MODE> key for approximately 3 seconds.
The switch-on image offers you to select the “System” parameters using the <F3> key,

Using the <F1> to <F4> keys, the burette offers you the possibility of changing the respective parameters
for RS-232-C communication. In this context, too, the new settings are to be stored using the <F1> key.
Subsequently, the <F5> or <MODE> keys will take you back to the function last selected.
