5.10 Connections to peripheral devices
The following devices and accessories can be connected to the K-375:
∙ up to 6 level sensors for monitoring the liquid level in storage or waste tanks
∙ a printer (via USB port) for printing e.g. results or methods
∙ a network cable (LAN) for storing data on a network or for communication with the optional
available PC software KjelLink
∙ a sampler K-376 / K-377 for automatic determinations of sample sequences
∙ a balance for the automatic acquisition of the sample weight
∙ a bar code reader for capturing sample data like IDs or batch numbers
∙ an additional external dosing unit for back titration

Connecting a printer
The K-375 supports printers with USB port and language PCL 3 or higher (PCL 5e, PCL 6, PCL 7 etc.
e.g. from Hewlett Packard).
The printer is connected to the USB port marked with “Printer” (position
5
in Fig. 5.1).
If the K-375 is connected to the network, it is also possible to use a network printer.
NOTE
For using the printer make sure to switch on the printer first, followed by the K-375.
5 10 2 Connecting a network cable
Instead of storing data locally on the instrument, it can also be stored on a network place. A network
cable can be connected to the device on the LAN port on the rear side. For adapting the network
settings refer to chapter “6.9.1 Settings
Network”.
More details regarding the network connection can be found in the document KjelMaster K-375 -
Manual - Network Connection, which can be obtained from any authorized BUCHI representative.
5 10 3 Connecting a KjelSampler K-376 or K-377
Connect the KjelSampler K-376 or K-377 to the KjelMaster K-375 by means of the supplied RS232
cable.
5 10 4 Connecting a balance
The connected balance must fulfill the following criteria:
∙ The balance must be equipped with an RS232 interface and a „print“-button. Otherwise it is not
possible to send sample weights to the K-375.
∙ The RS232 settings of the balance and the K-375 software must correspond.
∙ The sent command from the balance must have the following string: floating point_unit.
The weight is transferred to and stored in the K-375. Negative values are automatically converted into
positive sample weights.
For the configuration of the balance refer to
Settings
Peripherals screen (See chapter “6.9.1
Settings“).
