Operation via USB interface
• PC and CORIO CP are switched on.
• Connect the CORIO CP and PC with the USB cable
(JULABO accessory, Order no. 8 900 110).
• The CORIO CP reports to the PC after the installation of
the driver with the identifier "STMicroelectronics virtual
COM port" COM port in Device Manager
For comfortable operation, you can use the JULABO software
EasyTemp. There are also interface commands to the direct
query available.
232
Operation via RS232 interface
Use shielded cables only.
The shield should be continuous, and should be electrically
connected to the plug’s housing.
When working with the SERIAL interface, use a null
modem cable.
(JULABO accessory, RS232 Interface cable 9-pol./9-pol. , 2,5 m,
Order no. 9900110). Normal operation can be ensured only if
cables no longer than 3m (9.85 ft.) are used. The use of longer
cables does not itself affect proper performance of the device,
however external interference (e.g. cellular phones) may have
a negative impact on performance in this configuration.
Use this socket to connect a
PC via null modem cable to
the circulator in order to
remotely control the
temperature control system.
