2 Connect the three rinsing tubings that are connected to the tower 2
distributor to the rinsing nozzles.

2.1.15 Connecting the Polytron ®
The Polytron ® PT 1300 D is comprised of a control module and a dis-
persion drive with dispersion aggregate for mixing and shredding solid
samples. The control device is directed by a PC software, e.g. tiamo™,
via a serial RS-232 connector.
Please refer to the operating instructions of the Polytron for details regard-
ing connecting. The Polytron is connected as follows:
1 ￭ Connect the connecting cable of the dispersion device to the
front of the control module.
2 ￭ Check the set supply voltage on the connection socket on the rear
side of the control module.
￭ Switch off the instrument.
￭ Plug in the power supply cable and connect to a socket.
3 ￭ Connect the 6.2134.110 RS-232 connection cable to the 9-pin
connection socket on the rear side of the control module.
￭ Plug in the other end of the cable to the COM1 or COM2 port on
the PC. The port on the PC is usually marked with IOIOI.
If the PC has no serial interface, then a USB port on the PC can be
used with the aid of an RS-232/USB converter (e.g. the
2.145.0320 Edgeport).
Note
The Polytron must be registered manually in tiamo™ as an RS-232
device.
