5 RS-232-C interfaces, inputs and outputs
5.1 General
The TITRONIC
â
ââ
â
universal 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, & Fig. 7. RS-232-C
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).
PIN allocation of the RS-232-C interfaces:
PIN-
No.

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, & Fig. 26.

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.
